Title: The mulling of shoe uppers
Inventor: JUSTICE JOHN JAMES
IPC: A43D11/14
Filed: 1962-04-26
Abstract: 995,756. Boots &c. LOTUS Ltd. June 25, 1963 [April 26, 1962; Dec. 20, 1962 (2); April 3, 1963], No. 15873/62. Heading A3B. Shoe uppers are mulled by placing the uppers in an hermetically sealable chamber, sealing the chamber, evacuating the atmosphere from the sealed chamber, introducing a humidifying atmosphere into the evacuated chamber for a predetermined time and finally removing the mulled uppers, the processes of sealing, evacuating and mumidifying being effected automatically according to a predetermined timed cycle. As described the machine has two sealable chambers 201, 202 which are closed by lids 201a, 202a. Each lid 201a has a sealing ring (not shown) and is movable along rods 25 by piston and cylinders 23. Each lid 201a also carries a rail 201b having hooks 201c upon which the uppers are placed. Each of the chambers is connected to a source of vacuum 35 by conduits 36 having valves 37 and each is connected to a boiler 26 by a pipe 28 having two branches 28a, 28b which each have a valve 29a, 29b for controlling the admission of steam and a pressure release valve 29c, 29d. The water in the boiler 26 is maintained at a constant level by a float controled feed line (not shown) and is maintained at a temperature slightly below the boiling point of water at normal atmospheric pressure by a thermostatically controlled heater (not shown) so that when the pressure in the boiler is reduced the water will boil. The chambers 201, 202 are mounted in a housing 22 which has an inlet duct 30 having a radiator 31 through which water is circulated at a constant temperature and an extraction fan 33 so that air is circulated through the housing 22 to maintain the temperature of the chambers above the maximum dew point temperature. In operation the operator places the uppers on the hooks 201c and presses the buttons 40 to start the cycle of the machine in which the lid closes to seal the chamber, valve 37 opens to evacuate the chamber, valve 29a opens, thus reducing the pressure in the boiler 26 and causing the water to boil and drawing the steam into the chamber. After a predetermined time valve 29a closes, pressure release valve 29c opens and the lid 201a opens. The two chambers may be operated alternately or together. In a modification the temperature of the chambers may be maintained above the maximum dew point temperature by water jackets (not shown). In both embodiments the rail 201b carrying the uppers may be removable from the lid so that the uppers may be loaded on the hooks 201c prior to the rail being placed in the chamber and the humidifying atmosphere may be an atomised spray of water.

Title: Improvements in semi-conductor devices
IPC: H01L23/473
Filed: 1961-05-03
Abstract: 940,787. Semi-conductor devices. SIEMENS & HALSKE A.G. May 3, 1961 [May 5, 1960], No. 16018/61. Heading H1K. In a device comprising a PN tunnel junction in a semi-conductor material having a forbidden band energy gap less than that of germanium, the sum of the energy gap # n  between the Fermi level and the lower limit of the conduction band of the N zone and # p  between the Fermi level and the upper limit of the valence band of the P zone is less than the sum of the forbidden band energy gap and either # n  or # p . The valley current of the junction is reduced by this means and by operating at a low temperature. The voltage range over which the negative resistance region extends may be increased by making # n  and # p  equal and their sum as large as possible, and the maximum tunnel current increased by a reduction of the forbidden band gap. If the effective masses of holes and electrons differ in the semi-conductor material the device should be designed so that at the minimum current the hole and electron currents are balanced. This is done by making # n  greater than # p , when m n  is less than mp, and approximately equal to kT log. m p /m n . In an example, Fig. 3, in which large and small area degenerate N zones 4, 2 are formed by alloying to a P-type body 1, the large area is soldered to a liquid cooled plate 6. The device is used with the smaller PN junction forward biased.

Abstract: 1,097,322. Internal shoe drum brakes; fluid-pressure brakes. EATON YALE & TOWNE Inc. April 12, 1966 [April 21, 1965], No. 16075/66. Headings F2E and F2F. An internal shoe drum brake for heavy road vehicles, of the doubleacting two-leading shoetype, having a pair of roller-type wedges 29 arranged between respective pairs of plungers (32, 33, Fig. 3 not shown), engaging the respective pairs of adjacent ends of the shoes, is actuable by both service and emergency pistons of annular form arranged one behind the other so that on failure of the service piston the emergency piston can act through the service piston to apply the brake. In the embodiment of Fig. 2, each of the annular pistons 55, 55<SP>1</SP> slides within an annular cylinder 56 and is provided with outer and inner ring seals 62, 63. A pin 64 connects the service piston 55 to each wedge 29 whereby the wedges are operated when either hydraulic fluid or air is supplied to chamber 60 between the pistons. When, on failure of service pressure, fluid is instead supplied to chamber 62<SP>1</SP> both pistons move together to operate the wedges. In a modification (Fig. 4, not shown), the service piston consists of two parts (100), (102) secured together to clamp a diaphragm (84) between them, the diaphragm being in turn clamped between portions (66) and (94) of a cylinder assembly which is welded to an annular spider (72) fixed to an axle flange (27), the assembly being disposed almost entirely in the space bounded by the shoes so as to minimize space requirements and permit installation within a double wheel. A series of return springs (112) are spaced circumferentially around the spider (72), each being mounted on a pin (106) and engaging within a recess in the service piston. Guide members (114) including pads (118) of anti-friction material (Fig. 5, not shown), are attached to the service piston at points around its inner periphery to guide it and maintain its alignment whereby, on failure of service pressure, a rib (122) on the service piston can enter a corresponding recess (124) on the emergency piston (120) which is otherwise similar to that shown in Fig. 2. A further embodiment, together with a compressed-air system for service and emergency operation of such brakes both on a tractor and an associated trailer or semi-trailer, is shown in Fig. 7 wherein the service piston is a single annular member 172 to which a diaphragm 174 is bonded, the edges of the diaphragm being clamped between cylinder and cylinder head members 178, 182 formed from sheet metal. The emergency piston 190 includes a cushioning element 192 of resilient material. Air is supplied to service and emergency inlets 170, 195 via treadle valve 152 and dashboard-mounted emergency valve 206, respectively, the service air being supplied direct from a main reservoir 148 while emergency air is obtained from a separate reservoir 200 fed from the main reservoir via a non-return valve 202. The service supply system extends, as shown, direct to front and rear brakes on the tractor and also direct to the trailer brakes.

Title: Improvements in or relating to coin-freed mechanism
Filed: 1927-06-17
Abstract: 294,348. Mee, J., and Mycock, A. June 17, 1927. Diverting improper coins. - In coin-freed apparatus the coins are inserted in a coin channel 4, sloping down to the junction of an. operative branch 8 and a rejection branch 9. Proper coins either rebound from a magnet 11, Fig. 1, into the branch 8 or pass freely over the magnet, Fig. 3, which forms part of the base of the coin channel and one wall of the rejection branch. According to the invention, the magnet surface, which is closed to the interior of the coin channel and its branches, is continued in the direction of the rejection branch by non-magnetic material 13 which operates to detach iron discs from the magnet, when they are in a position to enter the rejection branch. The end of the magnet, Fig. 3, is sloped upwardly from the base of the channel 4 so that a proper coin can jump across the rejection branch 9 to the operative branch 8.

Filed: 1952-06-26
Abstract: 727,677. Stuffing-box substitutes. BRITISH INSULATED CALLENDER'S CABLES, Ltd. June 25, 1953 [June 26, 1952], No. 16147/52. Class 122 (5). Means for limiting the escape of fluid under super - atmospheric pressure from a vessel whilst a cable is being hauled towards and then through an outlet in the vessel by a lead wire 10, Fig. 2, of smaller cross-section than the cable, comprises a main sealing gland 3 designed to suit the size of the cable and an auxiliary gland 9 designed to fit the lead wire and to be automatically removable on the approach of the leading end of the cable. The gland 3 may be of the form described in Specification 651,634 while the gland 9 is in two or more parts which make joints in diametrical planes and is fitted with rubber sealing rings 13, 14. A projection 16 holds the auxiliary gland in its housing 4 until a cam 24, driven from a hauloff capstan for the lead wire 10, rocks a bell-crank lever 17 against the resistance of a spring 21 to release the gland 9 which is expelled by the pressure in the vessel. A guard member (not shown) prevents the parts of the gland from fouling the capstan. The cam is mounted on a slide to allow for thermal expansion and contraction of the vessel and is connected to its drive by a locking clutch which enables it to be set to lift the projection 16 at the appropriate moment on the approach of the cable. Fig. 3 shows an alternative arrangement in which the gland is made in two halves each mounted on a spring-loaded pivoted arm 41 which is released at the appropriate time by a cam-operated trigger 42. A sealing-ring 40 effects the seal with the housing 4. Fig. 5 shows a further alternative arrangement in which the auxiliary gland is made in two halves 52, 52<SP>1</SP> and provided with a circumferential groove 53 engaged by a bolt 54 connected to a spring-loaded piston 58. The latter is connected to a fluid-pressure supply through a spring-loaded piston 63, Fig. 6, which is released by a cam 71 as the leading end of the cable approaches to lift the bolt 54 and cause the gland to be expelled, the parts 52, 521 being arrested by a rubber-faced buffer (not shown). The cam 71 is driven by a pawl and ratchet from a cam 76 on a return pulley for the cable. The invention may form part of a machine for the vulcanization of rubber-covered cables.

Abstract: 457,780. Electrodeposition of tin and other metals. THOMAS & CO., Ltd., R., Shell Mex House, Strand, and KIEFT, A. W., Kendale, Hampstead Lane, Hampstead, both in London, MEHL, E., 6, Claremont Villas, Mumbles, and SMETANA, 0., 12, Eaton . Crescent, both in Swansea. June 4, 1935, No. 16159. [Class 41] Metal articles are electroplated with one or more layers of nickel, cobalt or copper, before electrodeposition of tin ; the tinned article is heated above the melting point of tin. For bright coatings the amount of the intermediate metal should be about 0À5 per cent of the tin. A matt surface may be obtained by depositing the intermediate metal in amount exceeding 20 per cent of the tin and extending the duration of the heat treatment. A thin layer of tin may be applied directly to the basis metal then the intermediate metal or metals and then the bulk of the tin deposit. One of the specified metals may also be applied both before and after the first thin coating of tin. The heat-treatment may be applied in the presence of cleaning or fluxing agents such as oils, resins, high-boiling alcohols or halides of sodium, potassium or ammonium, zinc or tin. Gaseous fluxing agents such as hydrogen, halogen hydracids, halides of ammonium or organic or inorganic acids may be employed. The tin coating should be allowed to remain molten for not more than 5 seconds. After heating the coating is quenched in paraffin, oil, alcohol or a soap solution or by a current of gas. Heating may be effected by direct application of gas flames. In the case of wire strip or tubing, heating may be effected electrically by passage of the material between a pair of contact members. The material is quenched before reaching the second contact. The finished article may be provided with a further electrolytic coating of tin which is also melted, as described in Specification 448,288. Specification 297,161, [Class 41], also is referred to.

Patent GB-459648-A (GB)
Title: Improvements in and relating to valves for compressors or the like
IPC: F04B49/24
Filed: 1936-06-10
Abstract: 459,648. Non-return valves. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. June 10, 1936, No. 16222. Convention date, June 11, 1935. [Class 135] A non-return valve for compressors or the like comprises a resilient valve disc 28 positioned on a valve plate 15 having a series of openings 17 unsymmetrically distributed about the centre of the disc, the disc restricting the flow through the openings by co-operation with an annular valve seat surrounding the openings. As shown in Fig. 2, the openings 17 extend over approximately two thirds of the periphery of the valve disc 28. The latter in its unstressed condition, Fig. 6, has a large central flat portion 37, bounded by a shallow conical edge portion 37<a> which faces the plate 15 on which the valve seat is formed. A disc-shaped valve-retainer 29 having its convex side towards the valve disc is clamped with the valve disc to the plate 15 by a rivet 31. The valve seat surrounds a groove 33 into which the openings 17 merge. Within the groove 33 are supporting seats 34 lying below the valve seat, the grooves 35 formed between these seats communicating with the groove 33 by a pressure equalizing slot 36. When the pressure on the outside of the valve disc exceeds that on the inner side, as for instance during the suction stroke of the compressor, the valve disc lies substantially flat on the inner seats 34 besides on the outer seat, but as the pressure on the inner side increases, it is progressively peeled from the seats until, when the pressures are equal, the edge only contacts the plate 15. On further increase of the pressure on the inner side of the disc, the latter is forced back against the retainer 29, and its edge raised clear of the plate 15. This construction of valve avoids sticking of the disc to its seat. In another form, the grooves 33, 35 are dispensed with and the openings 17 extend to the surface of the plate 15. In a further form having the grooves 33, 35, the disc is entirely flat in the unstressed condition. The valve according to the invention is shown embodied as the discharge valve in the valve assembly described in Specification 459,649, which has clamped to the plate 15, a muffle box 21 having inlet and outlet chambers 24, 26 and passages 25, 27 and an apertured plate 18 of springy steel or the like, a circular ended tongue 20 on which forms the inlet valve. The latter is provided with the unloading mechanism described in Specification 459,616, [Group XXVIII].

Filed: 1956-05-28
Abstract: 797,165. Endless-belt conveyers. NOE, O. May 28, 1956 [May 31, 1955], No. 16392/56. Class 78 (1). In a belt conveyer the belt 1 is carried on a series of cross-bars 2 each formed of two parts connected by a horizontal pivot 9 and is driven through a pair of cable chains 5 each located in the same plane as the adjacent edge of the belt, each chain and the adjacent edge of the belt being secured to each cross-bar by a two-armed releasable clamp 6, 7. The portion 6 of each clamp engages within a horizontal link of the chain while the end of the portion 7 of the clamp is shaped to conform to the U-shaped crosssection of the cross-bar 2, Fig. 2. A bolt 8 is passed through the clamp and bar 2 to tighten the clamp. The two parts of each bar 2 are formed with co-operating abutments 10 to limit the troughing of the belt in the upper run and hold the parts aligned in the lower run. Some of the bars carry rollers 3 engaging tracks 4, the roller stub-axles being directed at such an angle that they are equally inclined on the two runs. The bars 2 which are not equipped with rollers 3 may be replaced by transverse chains 17 and 18, Fig. 6, the former extending below the belt for supporting the upper run and the latter above the belt for supporting the lower run. In use, the conveyer can be assembled from a number of random lengths of belting which are overlapped, the overlapping portions being held by several successive clamps so that when it is desired to extend the belt it is merely necessary to slacken the clamps, insert extra lengths of chain and cross-bars, slide the belt portions so that they overlap by a smaller number of clamps, and re-tighten the clamps.
