Title: Idler rollers for conveyors
IPC: B65G39/09
Filed: 1971-07-07
Abstract: 1392809 Conveyer rollers BROCKWAY ENG CO Ltd 4 July 1972 [7 July 1971] 31786/71 Heading B8A A bearing assembly for a conveyer idler roller comprises a housing 16 non-rotatably mounted in a support 18 and carrying a ball-bearing 22, 23, 27. Inner race 27 is secured on a member 29 drivingly connected to a spindle 13 formed from hexagonal bar stock. A circular portion 33 of the spindle is a sliding fit in a bore 32 of the member 29 and a compression spring 35 provides end thrust between the spindle and a closure member 30. With a similar assembly at the opposite end of the roller, the springs tend to centralize the roller and load the bearings axially thus minimizing "chatter". Labyrinth seals 25 are provided. Roller bearings are also specified.

Title: Uhf preamplifier
IPC: H04B1/18
Filed: 1964-08-05
Abstract: 1,021,930. Preamplifier power supply. STANDARD TELEPHONES & CABLES Ltd. Aug. 5, 1964 [Aug. 7, 1963], No. 31798/64. Headings H3Q and H3T. A transistor UHF preamplifier for television and like receivers is powered by a supply unit which is connected in series with the power supply to the receiver. In Fig. 2 the preamplifier and its supply unit are in a casing 2 which is designed to be plugged into the mains at 8. Signals from the aerial enter at 9 and after amplification are passed on to the receiver at 5. The power current for the receiver along lead 6 flows through a current transformer in the unit 2 and the secondary winding feeds a full-wave rectifier and smoothing unit (Fig. 4, not shown) to supply the preamplifier. The casing 2 can be attached to the back of the receiver (Fig. 1, not shown). Alternatively (Fig. 3, not shown), the casing 2 contains the power unit only and the preamplifier is mounted next to the aerial. The arrangement of the invention avoids the necessity for a separate on/off switch for the preamplifier. The latter can be used with different types of receiver; a voltage stabilizer may be required in extreme cases. The plug 7 in Fig. 2 should have some blocking device to ensure that the casing 2 can only be inserted or remain in the mains socket while the plug 7 is in place.

Title: Dyeing polyethylene terephthalate film
Inventor: DAY MICHAEL CURTIS
IPC: D06P3/54
Filed: 1965-07-26
Abstract: A process for continuous dyeing of polyethylene terephthalate film (as defined) comprises applying to a travelling web of the film a pre-treatment liquid containing dye-carrier at a temperature of 15-80 DEG C and thereafter applying to the travelling web of the film a hot aqueous dye-bath containing a disposed dye suitable for dyeing polyethylene terephthalate.  Best results are obtained using polyester film which has been biasically orientated and heat-set. The pre-treatment bath is preferably at 20-40 DEG C and carriers include phenol, ortho- and para-phenylphenol, diphenyl, chlorinated benzenes, diphenyls, methyl salicylate, benzoic acid and benzylalcohol and mixtures of any of these compounds.  Various methods of improving penetration of dye include (1) increasing the time of immersion of film in the pre-treatment bath, (II) giving the film treatment with solvents or solvent vapour before treatment with dye-carrier or immersing the dyed film in vapours of solvents having swelling action, (III) giving the dyed film heat-treatment at 80-200 DEG C.

Abstract: 715,378. Vehicle tyres. WESTLAND GUMMIWERKE GES. Dec. 19, 1952 (Dec. 27, 1951], No. 32235/52. Class 144(2) To prevent flattening under heavy loads a solid rubber tyre 1 for commercial vehicles is compressed between the two portions 2 of a divided rigid rim to leave only the tread region of the tyre projecting beyond the rim, such projection being insufficient to allow lateral spreading of the tread under load. As shown the tyre is compressed between two halves of a wheel disc by transverse bolts 3, axially inwardly directed flanges 4 on the periphery of the rim portions 2 of the disc-halves engaging in grooves in the tyre to exert radial compression of the tyre. In an alternative arrangement radial precompression is obtained by a rim of frusto-conical section having radially outwardly converging sides.

Abstract: The individual particles of free-flowing, crosslinkable, thermoplastic or elastomeric base material are brought into high-energy motion. During or before this motion, graftable antioxidants and other additives are added to the base material and then diffuse into the surface of the particles by diffusion and are homogeneously distributed. This makes it possible, during later crosslinking, to graft the antioxidants onto the base material so that they can no longer volatilise.

[Classes 35 and 38 (iv)] Running generators in parallel or in series. - Alternators driven independently are maintained in synchronism when their excitation is reduced or removed, by auxiliary windings of a coil pitch which is an even multiple of that of the main windings, the auxiliary windings of all machines being in parallel. Fig. 1 shows an auxiliary winding 2 of twice the pole pitch of the main winding 1. The voltages induced by the normal field system in the conductors of the auxiliary winding neutralize each other, but by reversing adjacent poles of every other pair the voltage conditions in main and auxiliary windings are reversed so that synchronizing currents are them operative in the latter, while the circuits of the former may be opened, to permit, for example, changes in the circuits of a ship propulsion system. Such a system may comprise a motor constructed with similar auxiliary windings for braking purposes as described in Specification 521,151, and the field control of this may be co-ordinated with that of the alternators. The invention is applicable to series-connected alternators. Any desired ratio between the voltages induced in the main and auxiliary windings may be obtained by suitable excitation of the respective pole groups.

[Also in Group XXXI] A vehicle hydraulic transmission system has control apparatus located in the return line 10 from motor H to a reservoir comprising a pressure limiter G 1 , regulated by a dial control 8, and a brake valve F 1 , controlled through pilot line 3 by the pressure in the supply line 1 to the motor H. The system further comprises a rotary pump B, change speed and reversing devices D and E, non-return valves 21, 22 in the supply lines 1 and 2 and for use when the motor is reversed, a further brake valve F 2 , pilot line 4 and pressure limiter G 2 . The brake valve F 1  (Fig. 2) comprises an opening 12 connected to line 3, an inlet part 14 connected to the motor, an outlet part 13 and a piston 15, shown in its closed position, which is moved upward against spring 16 by increasing pilot line pressure to progressively increase the passage area between parts 13 and 14. A modified valve (Fig. 3, not shown) has an additional radial passage so that passages 13 and 14 are always in communication and a non-return valve in piston 15 permitting fluid flow into the pilot line. Vehicle speed may be controlled when travelling downhill since the motor reduces the pressure in supply line 9 and hence pilot line 3 closing brake valve E 1 , the pressure in line 10 being determined by limiter G 1 , which is suitably adjusted. When the fluid flow from device E is reversed the pressure in lines 2, 10 and 4 increases opening brake valve F 2  and progressively stopping motor H before it rotates in the opposite direction.
