Title: Apparatus for and method of stitching tires
IPC: B29D30/28
Filed: 1951-05-23
Abstract: 698,973. Tyre-building apparatus. WING- FOOT CORPORATION. May 23, 1951 [Nov. 13, 1950], No. 12038/51. Class 144 (i). In a tyre-building apparatus component plies are stitched together on a rotatable tyre-building drum 4 by a tacking wheel 44 which tacks the material together at spaced points in advance of a smooth-faced stitcher wheel 20 to prevent stretching and wrinkling of the material, the tacking wheel 44 being mounted appreciably in advance of the stitcher wheel 20 on a common support 16 arranged for movement axially of the drum as the latter rotates. As shown, a pair of smooth-faced stitcher wheels 20 are mounted respectively on right- and left-hand screw-threaded portions of a shaft 22 fixed between two brackets 7 which are slidably mounted on support pillars 5 and are operable by fluid pressure piston and cylinder elements 25, 26. The brackets 7 support a squaresection shaft 15 which slidably guides the ends 17 of stitcher support arms 16, in bosses 18 of which the stitcher wheels 20 are mounted. The tacking wheels 44, which have peripherally spaced radial projections 48, are mounted on spring-actuated plungers 34 having limited sliding movement in forked extensions 33, of the bosses 18, which are positioned so that the tacking wheels 44 engage the tyre plies axially and peripherally in advance of the respective stitcher wheels 20. In operation, the stitcher assembly is advanced towards the drum to allow the tacking wheels 44 to engage the plies and be depressed against their springs 36 until the plain faced stitchers 20 engage the plies. Rotation of the drum rotates the wheels 20, 44 and causes axial translation of the arms 16 toward the drum ends, return movement being effected by engagement of the wheels 20 in their retracted position with a rotating rubber roller 27.

Title: Clock utilising a magnetic stepping mechanism
IPC: G04C3/10
Filed: 1973-03-13
Abstract: 1422994 Electric clocks JECO KK 13 March 1973 12127/73 Heading G3T [Also in Division F2]  In an electric clock having a stepping wheel 25 which is fixed to a vertical shaft 27 and is advanced by magnetic co-operation with an oscillator 32 vibrating in a horizontal plane, an inertia wheel 23 is loosely mounted on the shaft 27 so as to be rotatable with respect to the shaft but able frictionally to engage it when subjected to a side thrust. Bearings for the shaft 27 are located on projecting portions of a metal frame plate 24, the lower bearing (29), Fig. 5 (not shown) using a single jewel and the upper bearing (28) being of beryllium bronze. The other frame plate 31 is of synthetic resin. The shaft 27 is of hardened steel and has a portion of reduced diameter d carrying a stainless steel worm coil 45 which drives a synthetic resin wheel 43 and thus the clock train. The oscillator 32 is a tuning fork one tine of which carries a magnet 34 embracing the wheel 25. The other tine carries a magnetic part 37 which co-operates with a driving coil 39 energized by an electronic block (40), Fig. 1 (not shown) from a battery carried in a compartment (13) of the clock framework. Regulation is performed by adjusting a screw 30 carrying a magnet 61. The oscillator base 51 is attached to one end 50 of a plate 41, another end 52 of the plate being fixed by a screw 53 to a mounting block 42 and the frame plate 24. The block 42 is made of a sintered, porous alloy of brass and lead to reduce leakage of vibration energy to the framework. Leakage is also reduced by a slit 49 in the mounting plate 41. To start rotation of the wheel 25, a lever (16) is deflected and allowed to spring back, kicking the inertia wheel 23 as it does so. Friction between the wheel 23 and shaft 27 is then such that the shaft and the wheel 25 are brought progressively up to synchronous speed. To set the clock, a knob 57 is turned to rotate a shaft 56 and thus a wheel 55 and the clock hands (not shown). Alternatively, a further shaft which projects beneath the clock may be axially displaced to bring a pinion (59), Fig. 9 (not shown) thereon into mesh with crown teeth 58 on the wheel 55.

Title: Improvements in resinous compositions
IPC: C08K3/00
Filed: 1944-06-26
Abstract: Polymers and/or copolymers of vinyl chloride are stabilized by p adding to thermoplastic compositions of these resins a non-reducing alkali or alkaline earth metal, ammonium or substituted ammonium salt or salts of an inorganic acid, said salt or salts being soluble in water to give a solution having a pH greater than 7, in an amount at least sufficient to combine with substantially all the free hydrogen chloride liberated from the said polymer and/or copolymer at the temperatures reached during subsequent manipulation.  Salts preferred are meta phosphates, borates, silicates and carbonates.  A dilute solution, particularly an aqueous solution, may be used to incorporate such salts into the resin, the composition then being dried to deposit the salts.  In an example, vinyl chloride is polymerized in aqueous emulsion, coagulated with aluminium sulphate and washed with hot water, a sodium silicate solution then being added.  Methyl glycol phthalate and ethyl oleate are then mixed in with the stabilized resin.  Dibutyl phthalate and stearic acid may also be used.  Tubes are made from a vinyl-vinylidene chloride copolymer which is mixed with sodium borate, this salt being used to coagulate the copolymer emulsion, dioctyl phthalate being added to the dried stabilized resin. Specifications 450,856, 518,189, 526,345, 572,875 and 583,290 are referred to.

Title: Improvements in telephone or like systems
IPC: H04Q1/446
Filed: 1943-07-27
Abstract: 567,164. Exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., GILLINGS, C., and RHODES, C. July 27, 1943, No. 12179. [Class 40 (iv)] The talking circuit at the incoming end of a junction over which voice frequency signalling is employed includes a variable attenuator of the biassed rectifier type which, on the receipt of signals, is biassed to produce maximum attenuation and thus to block the circuit beyond the signal receiver. As shown, the attenuator is connected between transformers T1, T2 and is normally biassed so that the series rectifiers MRC, MRD are conductive while the shunt rectifiers MRA, MRB are non-conductive. On the operation of relay CA (not shown) in response to a signal, this condition is reversed and in effect a low resistance shunt is placed across the line. The transformer T2 has a centre-tapped tertiary winding which is shunted by resistances YE, YF and rectifiers MRE, MRF in order to provide a suitable line termination in both directions, this termination being eliminated on the reply of the called party by the operation of relay IR (not shown) which alters the bias to render the rectifiers MRE, MRF non-conducting. The loss introduced by the line termination is such that conversation is not seriously impaired on non-metered calls when relay IR is inoperative. A condenser QA provides a low impedance path for voicefrequency currents which might affect the distribution of the bias potentials.. Specification 560,794 is referred to.

Filed: 1920-05-03
Abstract: 168,938. Watson, W., Jones, D. W. Kent-, and Woodlands, Ltd. May 3, 1920. Food preparations.-A flour-improver is produced by treating flour with a halogen or a compound containing available halogen. Instead of wheat flour, flour of other grain, such as barley, rye, or rice, or pea, bean or soya bean flour, or constituents of flour or substances containing them such as starch, maltose, dextrine, albumen, semolina or tapioca, may be employed. According to one example, a quantity of flour is stirred in a closed vessel into which commercially pure chlorine is led, and the treatment continued until the flour contains 2 to 3 per cent of its weight of combined chlorine. It is used as an improver by adding one-half to one pound to 280 lb. of flour or dough before baking. Hydrochloric acid, preferably in the gaseous state, may be substituted for the halogen. Specifications 1661/01, 16938/13, and 165,149, [all in Class 58, Grain &c.], are referred to.

Title: Improvements in or relating to hay making machines
IPC: A01D78/16
Filed: 1964-03-25
Abstract: 1,049,172. Haymaking machines. C. VAN DER LELY N.V. March 25, 1964 [April 20, 1963], No. 12748/64. Heading A1F. A rake-wheel type of haymaking machine employs a plurality of co-axial rake-wheels some of which are rotated by ground-contact whilst the others are mechanicallydriven. In Figs. 1 and 2 a machine frame comprises two beams 1, 2 secured together in T-shape. The ends of the limbs carry swivel-wheels 3, 4, 5 supported by parallel linkwork, such as 6, 7, the working height of the frame being adjustable by means such as the lever 6a operable by a cable 6b. The swivel-axis of the rear swivelwheel 5 is lockable by a detent 9a, 9b. A tube 13 is rotatable on the beam 1 in ballbearings 12 and is driven by bevel-gearing 23, 24 from the power take-off 26 of the towing tractor (not shown). Discs 14, 17 are integral with the tube, the discs 14 carrying the driven rake-wheels 16 through spokes 15, and the discs 17 carrying freelyrotatable rake-wheels 21 through ball-races 18 and rings 19. The ground-driven rakewheels are of larger diameter so that the tines of the mechanically-driven wheels 16 do not touch the ground. In a modification (Fig. 3) both sets of rake-wheels can be angled to the axis of the tube 13, for swath-production, and, when so angled, all the wheels are driven by ground contact, but in the rectilinear position (shown dotted) half the wheels are anchored to the driven tube 13. The ground-driven rakewheels 21 simply have their inner discs 27 pivoted to the tube 13 by lugs 32 and vertical pins 33. As shown in Fig. 5, the mechanically-driven rake-wheels 16<SP>1</SP> are similarly constructed, the outer ring 29 being secured to the inner disc 27 by a pin 31 entering lugs 38, 39. When the discs are angled, the wheel drops relatively to the shaft 1 and tube 13 so that the pin 31 no longer engages lug 39, thereby freeing the outer ring and tines 15<SP>1</SP> for groundinduced rotation; the tines 15<SP>1</SP> then contact the ground.

Abstract: 529,904. Journal bearings. BRISTOL AEROPLANE CO., Ltd., and FEDDEN, A. H. R. April 28, 1939, No. 12800. [Class 12 (i)] [Also in Group XXVI] The crank pin 14 encircled by a master bigend in a radial cylinder I.C. engine or a similar journal having a pressure sector A-A in which the load tends to be concentrated is fitted with a unitary bush 19 of which at least the outer layer 44 is of bearing metal the surface of the bush being formed outside the pressure sector with an approximately rectangular network of -grooves 50, 51, 52 to. which oil is supplied. The crankshaft comprises split crank-webs 12, 13 having their ends bolted together to clamp the crank pin 14 to which the bush 19 has previously been secured by an " interference fit." The bush 19 may consist of a steel shell having an outer layer of bearing metal secured by welding, rolling, electro deposition, chemical deposition &c. and is slid over the pin whilst heated, the crank-pin being cold or cooled. Fretting between the engaging surfaces may be prevented by electroplating the inner surface of the bush with silver. Oil is supplied to the grooved network' in the bearing surface through bores 40, 41, 42, 141, 140 in the crank webs and pin, and a tubular bolt or bolts 43 passing through radial holes in the crank pin. The bolt 43 screws into a nut 45 in the bore 42 and is formed with an enlargement 48 which prevents creeping of the bush 19 on the crank pin. The bolt 43 is initially formed with a grooved non-circular head which is sheared off by the screwing operation. The master connecting rod 21 is formed with flanges 22, 23 to support the wrist pins 24 of the auxiliary connecting rods 26. The wrist pins 24 are fitted with bushes 27 of bearing metal and are held in place by bolts 28 engaging nuts 29 fitting in recesses in a locking plate 30 surrounding the crank pin. A ring 36, plate 37 and the plate 30 . control the escape of oil from the left side of bearing.
