IPC: F42B22/10
Filed: 1967-05-23
Abstract: 1,140,170. Time control of electric circuits. E.G. & G. INTERNATIONAL Inc. May 23,1967 [May 23, 1966], No. 24015/67. Heading G3T. Movable apparatus such as buoyant under water equipment is released from movement preventing securing mechanism by means actuated electrically by a signal released by a time delay means after the latter has received a predetermined number of electrical impulses. Closure of switch S by a rotary cam 7 applies a series of pulses to the base of a transistor Q1 to render it intermittently conducting thereby causing a further transistor Q2 to apply a series of pulses to a relay coil RL. After receiving a predetermined number of such pulses the relay coil RL actuates a switch S1 to energize an electrically operable squib cartridge 8. The latter then releases a linkage Fig. 1 (not shown) connecting a floatable underwater equipment, such a monitoring or sensing apparatus to an anchor or mooring. A tether line may be stored in a container adjacent the floatable apparatus for tethering the latter when released to the anchor or mooring to prevent drifting.

Filed: 1975-05-02
Abstract: 1504280 Reducing inclusions in castings GR-STEIN REFRACTORIES Ltd 2 May 1975 [30 May 1974] 24032/74 Heading C7D [Also in Division F4] In order to reduce the inclusions present in vacuum induction cast metals containing aluminium, at least the surface of the melting crucible is formed of a refractory material which, in use, has a viscous surface layer to which the inclusions adhere when the melt is subjected to centrifugal forces. The refractory material has MgO, CaO and SiO 2  as its major constituents, with a CaO/SiO 2  ratio of at least 1À5/1 and a CaO content of 1À5- 5À5%. Alternatively the refractory may comprise MgO, CaO and ZrO 2 , the CaO/ZrO 2  ratio being 0À455 with a ZrO 2  content of 15%, possibly as preformed calcium zirconate. In both cases, the increase in CaO over the normal content provides the viscous layer by reaction with the Al in the melt and the MgO of the crucible.

Title: Improved treatment of hydrated cellulose
IPC: D06M15/41
Filed: 1927-09-13
Abstract: 278,684. I. G. Farbenindustrie Akt.- Ges. Oct. 5, 1926, [Convention date]. Plastic compositions containing amorphous cellulose.-The tendency to swell shown by regenerated cellulose, is diminished by treating the freshly-precipitated or already-dried hydrated products with an aqueous neutral or feebly alkaline solution of a condensation product which is capable of undergoing further condensation, either by itself or on treatment with a further substance such as formaldehyde, to produce a product insoluble in water or dilute alkali solution. Instead of a formed condensation product, materials giving rise thereto may be employed. The saturated material is then subjected under neutral or alkaline conditions to the treatment necessary to convert the soluble condensaion produet into an insoluble product. Suitable condensation products are artificial resins such as sulphur-phenol resins and the sulphur-phenolformaldehyde resins which are soluble in water or alkali: the condensation products or urea and formaldehyde may also be used. Neutral or feebly alkaline catalysts may be added to facilitate the condensation and a softening agent may be introduced to modify the brittleness and elasticity of the final product. In examples, hydrated cellulose is treated with a solution of a sulphur-phenol-formaldehyde resin, then immersed in formaldehyde solution, and finally dried at about 145‹ C. ; hydrated cellulose is soaked in a solution containing formaldehyde, hexamethylenetetramine, urea and lactic acid, and then dried at 50-150‹ C.; hydrated cellulose is immersed in a solution of sulphur-o-cresol resin as described in Specification 186,107, [Class 2 (iii), Dyes &c.], containing a small proportion of ammonia as catalyst, then treated with formaldehyde solution, and finally driel at 130-150‹ C. Drying at higher temperatures generally yields a harder and more brittle product; at lower temperatures the products are more plastic and soft. The colour of the product can be varied according to the colour of the selected condensation product.

Title: Dispensing equipment
IPC: B65G47/14
Filed: 1963-06-18
Abstract: 1,041,715. Hoppers; rotary conveyers. F. K. NABIULLIN, R. G. ADAMJAN, Z. M. BUZOVA, S. A. GANTMAN, E. M. GERTSIK, I. I. ZHURAVLEV, B. V. MARFIN, H. V. SLADKOVA, S. S. SHLIONSKAYA, and L. N. KOSHKIN. June 18, 1963, No. 24187/63. Headings B8A and B8S. Apparatus for dispensing articles singly from a bulk supply consists of a hopper 1, a feed wheel 2 in the form of a horizontal rotary disc with radial passageways 3 (Fig. 2, not shown) for receiving the articles, and an associated rotary conveyer 9 having peripheral grippers 10, this conveyer being rotated at the same speed as the wheel 2 and its grippers being operable to take articles one at a time from the outer ends of the passageways. Hopper discharging.-The hopper outlet opens into a chamber within which a conical deflector 5 is rotated in the opposite direction from the feed wheel 2. At the end of each radial passageway 3 is a pair of retractible stops 12 and 13 which are operated to allow the release of the outer article as it enters the path of the grippers 10. Rotary conveyers.-The conveyer 9 consists of a plurality of rods projecting radially from a rotary disc, each rod carrying at its outer end grippers 10 for taking hold of articles released from the feed wheel 2. These rods are independently rotatable about their respective longitudinal axes, to allow for an article carried by their grippers to be inverted. Orientating articles.-Each article released by the stops 12 and 13 encounters a feeler stop 11 incorporating a plunger 7, and a dished article such as a battery top (Figs. 3 and 4, not shown) having its convex face downward will depress this plunger to make a switch contact 7a. This switch effects movement of a cam arm 16 (Fig. 5a, not shown) into the path of a rotary disc 8 to depress one of a plurality of studs mounted therein. Any stud so depressed subsequently makes a switch 17 (Fig. 5a, not shown) before being reset to its upper position by a further cam (22). Each operation of this switch 17 effects downward movement of a cam 24 (Fig. 6, not shown) which raises a peg 28, hitherto moving along a horizontal guide passage, into an upwardly inclined passage. These passages run round the periphery of conveyer 9 and cause a rod 26, to which the peg 28 is attached, to be raised. These rods are in mesh with the rods 15 of the rotary conveyer, which are thus rotated to invert the article carried by the associated grippers 10. Thus the plunger 7 detects improperly oriented articles on the feed wheel 2 and the disc 8 temporarily records the misorientation and subsequently causes re-orientation of the relevant article whilst on the conveyer.

Title: Electron imaging tubes
IPC: H01J29/44
Filed: 1971-04-19
Abstract: 1337650 Image pick-up tubes WESTING- HOUSE ELECTRIC CORP 19 April 1971 [20 March 1970] 24195/71 Heading HID In an image pick-up tube wherein electrons from a photocathode impinge on a secondary electron conduction (SEC) target which is scanned by an electron beam to produce the output signal, the SEC layer is supported on a grid which has sufficient thermal capacity and thermal conductivity to prevent the SEC layer from being destroyed by the heat generated by the photo-electrons when the photocathode is strongly illuminated. In Fig. 2 the grid comprises a copper mesh 58, 13 microns thick having 1000 meshes per inch and is brazed with a gold braze to a support ring 50. A gold coating 1000Š thick may be evaporated on to the right side of the mesh and fused in an atmosphere of forming gas at 650‹ C. for one hour, which also tightens the mesh. A coating of aluminium 500-2000Š thick may be evaporated on both sides of the mesh to further strengthen and tighten it and also to protect the copper from oxidation. An organic lacquer film is deposited on the right side of the mesh and dried, and a 2 micron layer 60 of aluminium is evaporated on to it, after which the lacquer is removed by baking in hydrogen. This layer 60 forms the signal layer and is connected to an output lead (not shown). Finally a 20 micron layer 62 of potassium chloride is evaporated on to the layer 60 to provide the SEC layer. The structure shown includes a nickel suppressor mesh 64 supported by rings 54 and 56 and spaced 0À010 inch from the target by a ceramic spacer 52. Under high illumination the target may receive a photo-electron current of 5 milliamps/ cm<SP>2</SP>., and the consequent temperature rise of the layer 62 may be limited to 100‹ C. The thermal capacity and conductivity of the target may be 750 x 10<SP>-6</SP> Joules/cm<SP>2</SP>./‹ C. and 630 x 10<SP>-6</SP> watts/ ‹C. compared with 65 Î 10<SP>-6</SP> Joules/cm<SP>2</SP>./‹C and 10 x 10<SP>-6</SP> watts/‹C. in a known target. The grid 58 also prevents microphony. The photocathode may be provided on an inner concave surface of a fibre-optics faceplate (Fig. 1, not shown).

Title: Improvements in apparatus for automatic playing of the violin or other stringed musical instrument played with a bow
IPC: G10F1/18
Filed: 1926-10-02
Abstract: 259,566. Aubry, E., and Boreau, G. Oct. 7, 1925, [Convention date]. Addition to 200,505. Stringed instruments.-The construction described in the parent Specification is modified in respect of (a) the bow mounting, and (b) the mounting of the instrument. (a) The pressure of the bow on the string is maintained constant during the stroke by increasing the pressure applied to the bow-holder during the passage of the bow from heel to point, thus counteracting the increased resiliency. The bow a is held between upper and lower rubber blocks b<2>, b<3> in a holder b pivoted at b<1> on a carriage c moved along rails e, e<1> by wires c<6>, c<7> as in the parent Specification. Hinged to the carriage c at f<2> is a smaller carriage f, running on a rail d<1> passing through it, and connected by links g, g<5>, g<7> to the holder b at g<8>. The link g<5> extends beyond the fulcrum g<6> and carries rollers h<2> running on a rail a pivoted at d<2>. Collapse of bellows d<5> under the control of the perforated record-sheet raises the end d<3> of the rail d, and as the carriage c moves to the left bringing the bow from heel to point over the string i, the rollers h<2>, fulcrum g<6> and pivot g<8> are raised, increasing the bow-pressure. Further control of the bow-pressure may be obtained by a similar collapse of bellows d<6>, tilting the rail d<1> and lifting the link g. The bow a may be adjusted in the holder b about the stick as axis. (b) The instrument is rocked under the bow to bring the required string into playing position, with an added straight-line transverse movement, so that the arc in which the strings lie has a rolling motion under the bow. The cradle m is pivoted at m<1> on the carriage k, and is connected by two pairs of links n<1>, n<2> to pulleys n loosely mounted on the carriage and connected by links n<4> to fixed points n<5>, so that on drawing the carriage transversely between guides as l<2>, by the operation of bell-cranks p<1> by means as described in the parent Specification, the cradle is simultaneously tilted, producing a rolling motion under the bow.
