Title: Improvements in or relating to spring mountings for vehicle wheels
IPC: B62K25/16
Filed: 1950-11-08
Abstract: 691,551. Resilient mountings. INVACAR, Ltd., and GREEVES, O. B. April 24, 1951 [Nov. 8, 1950], No. 27342/50. Class 108 (iii). [Also in Group XXXI] In spring mounting means for a vehicle wheel 36 which is located between two limbs 10, 10 of a fork, the wheel axle 33 being mounted between two lever arms 32 pivotally connected to the mounting, the pivotal connection comprises a rubber bush 23 bonded between two concentric elements 21, 22, the inner element 22 being fixed to a limb of the fork, while the outer element 21 is fixed to the lever arm 32. Spaced lugs 20 are provided on the ends of each fork limb. A self-gripping washer 24 is arranged between each end of the inner element 22 and an inner face of one of the lugs 20. A bolt 26 extends through holes in the lugs 20 and through a hollow plug 25 within the element 22 and clamps the lugs 22 against the washer 24 and the end of the element 22. Each lever arm 32 extends rearwardly from a cylindrical socket member 31 which is welded to the outer element 21. Each lever arm may either be directly attached to the socket 31 or may have a hub portion which embraces the socket. A U-shaped element 35 straddles the wheel and is welded to one of the lever arms 32 and/or the socket member 31. A plate 38 is pivotally mounted at one end of the wheel spindle 33 and carries a brake mechanism (not shown). The torque reaction of the brake forces on the lever arm 32 are counteracted by a lever arm 42 fixed to the plate 38 and pivotally connected by a link 43 to a lug 44 on the fork member 10.

Title: Production of rubber and synthetic resin materials in expanded form
Inventor: REED RONALD ARTHUR
IPC: C08J9/10
Filed: 1953-10-06
Abstract: Synthetic resins are expanded by heating, preferably in the form of a moulding powder, with terephthalazide which is decomposed into nitrogen and p-phenylene di-isocyanate.  After expansion by the nitrogen thus released the synthetic resin may be further expanded by heat treatment, preferably in the presence of hot water or steam, which reacts with the p-phenylene di-isocyanate to produce carbon dioxide.  The synthetic resin may be polyvinyl chloride or a copolymer thereof, polyethylene, polymethacrylate, urea-formaldehyde or phenolformaldehyde.  In an Example 5 parts of powdered terephthalazide, 3 parts calcium stearate, and 100 parts polyvinyl chloride are mixed dry and stirred into 250 parts dibutyl phthalate. The dispersion is changed into a mould, heated for 15 minutes at 165 DEG  C. and 600 lb. per square inch pressure, and then cooled under pressure for 25 minutes.  Thereafter the moulded material is expanded by heating in a water bath at 80 DEG  C. for 35 minutes.  In a further example, water is added to the initial mixture of polyvinyl chloride and other ingredients.  A third example is described in which 50 parts epoxy are part terephthalazide, and a dispersing agent one mixed and 3-4 parts of diethylene triamine are added.  After standing 30 seconds the mass rises and is then hardened by heating at 60 DEG  C. for 2 hours.  Reference has been directed by the Comptroller to Specification 719,102.ALSO:Expanded rubber or synthetic resin material is prepared by heating the rubber or other material (which is preferably in the form of a moulding powder) with terephthalazide.

Abstract: 821,783. Ventilation. CARRIER ENGINEERING CO. Ltd. Aug. 30, 1957 [Oct. 18, 1956], No. 27460/57. Class 137 A room air-conditioning unit comprises a plenum chamber 12 which is supplied from a central source with primary air through inlet 20, and a heat-exchanger 25 connected by pipes 28, 29 to a central source to permit a heating or cooling medium to be passed therethrough. Primary air is discharged from the plenum chamber through nozzles 31 and thus induces secondary air from the room to enter chamber 23 through intake louvres 34, pass through the fins 37 of the heat exchanger and mix with the primary air in chamber 24, the mixture being discharged through exhaust louvres 34. Slats 38, 39 and slat 40 and wall 43 act as second and third nozzles respectively to ensure maximum contact between the heat exchanger and the secondary air. Shortcircuiting of the air between chambers 23 and 24 is prevented by louvres 35, 36, wall 26 and wall 27 (not shown). Any condensate which forms in the unit is collected on plate 30 and flows out through fitting 46; if the unit is used on its side, wall 48 and fitting 49 collect and dispose of the condensate. To reduce noise, the plenum chamber is made of sound absorbing material and is provided with a baffle 15 made of such material. Specification 764,108 is referred to.

Title: Dynamic focusing signal generator

Filed: 1973-06-13
Abstract: 1372678 Cathode-ray tube circuits HUGHES AIRCRAFT CO 13 June 1973 [19 July 1972] 28127/73 Heading H4T  A dynamic focusing signal generator for a cathode-ray tube supplied with X and Y deflection signals utilizes the square-law relationship between the drain current (output signal) and the gate-to-source voltage (input signal) of a field effect transistor. The Specification considers the mathematical relationship between the input and output signals and shows that the latter consists of the square of the input signal together with a component which is a linear function of the input signal so that the desired square function may be derived by algebraic addition of an appropriate portion of the input signal to the output signal. Fig. 1, shows the described embodiment and Fig. 2 shows waveforms which occur at various points in Fig. 1 in respect of the operation of the left-hand portion concerned with X-deflection inputs, the right hand side, which is concerned with Y-deflection inputs being identical although the magnitude and frequencies of the X and Y-deflection inputs may be different. As shown, an X-deflection input 70 is amplified by transistor amplifier 32 and a portion 71 of the output at terminal 25 is employed as input signal to the gate electrode 52 of field effect transistor 50 the signal developed at the drain 54 of which is as shown by waveform 73. This includes the unrequired linear component and the latter is then eliminated by adding thereto the signal 72 at terminal 27 to produce, at terminal 68 the required focusing signal 80 in respect of X-deflection focus correction. Adjustable resistor 63 sets the D.C. level, adjustable resistors 66 allow symmetrical adjustment of the X and Y components and diode 61 prevents negative excursions of the output signal for circuit protection.
