Abstract: 529,862. Wireless receiving circuits. GENERAL ELECTRIC CO., Ltd., BLIGH, N. R., and BLOCH, A. June 9, 1939, No. 16956. [Class 40 (v)] In a radio receiver particularly for short wave television reception on a single wavelength, intermediate frequency drift is reduced by making the local frequency proportional to the intermediate frequency. The natural frequency of the local oscillator is adjusted to be close to the intermediate frequency and is then made equal to the intermediate frequency by the local oscillator being forced by the intermediate oscillations. The desired local frequency is then obtained from the oscillator by means of a frequency multiplier. Specification 415,051 is referred to.

Title: Warning indicator light device for motor vehicles
IPC: H05B39/09
Filed: 1964-04-29
Abstract: 1,058,268. Road traffic signals on vehicles. W. SCHILLING. April 29, 1964 [April 30, 1963], No. 17773/64. Heading G4Q. A flare signalling arrangement for indicating that a vehicle is stationary comprises means for flashing the turn indicating lamps either simultaneously or alternately on each side of the vehicle. When the ignition switch 13 is closed, relay 15 is energized and the circuit shown acts as a turn indicator. When switch 12 is moved to contact 17 energy is supplied to terminal 18 of a transistor flasher unit which alternately energizes and de-energizes relay 16. Energy is also supplied to the contact opposite contact 19 of relay 16 so that the relay causes periodical excitation of lamps 1a and 1c via terminal 21. Similarly when switch 12 is moved to contact 22, the transistor flasher is energized through terminal 24, and another contact of relay 16 is energized so that lamps 1b and 1d are periodically energized via contact 23. For flare operation the ignition switch 13 is opened so that relay 15 is de-energized and its contact 20 is connected to the opposed contact as shown. Both opposed contacts of relay 16 are now energized if switch 12 is in either of its " on " positions so the lights on each side of the vehicle flash alternately. In an alternative method of operation, contacts 19 and 23 are connected together through contact 25 of relay 15 and the connections shown by dotted lines, and all four lamps flash together. The current supplied to the four lamps is sufficient to operate relay 10 and thereby light an indicating lamp 2.

Title: Improvements in or relating to plasticized high acetyl cellulose acetate compositions
IPC: C08L1/12
Filed: 1955-06-21
Abstract: Plastic compositions comprising cellulose acetate of acetyl value (as combined acetic acid) at least 57 per cent and an intrinsic viscosity of at least 1.6, and a plasticizer of low solvent power for the cellulose acetate in intimate fusion therewith, are prepared by heating an intimate mixture of the cellulose acetate and the plasticizer in particulate form with mastication to a temperature sufficiently high to cause the mixture to fuse and form a homogeneous melt, which is then cooled to room temperature.  The term /aintrinsic viscosity/e is defined.  A plasticizer of low solvent power is defined as one which forms a homogeneous melt when heated with the cellulose acetate flake in the proportion 7/3 at 450 DEG  F., but separates from the cellulose acetate on cooling the melt to room temperature.  The plasticizer may be dibutyl, di-isobutyl or butyl benzyl phthalate, butyl phthalyl butyl glycolate, diethylene glycol dibenzoate, the adduct of equimolar proportions of ethylene oxide and nonyl phenol, or diethyl phthalate used with triphenyl phosphate in 1 : 1 ratio, di-isobutyl phthalate being preferred.  The acetyl value of the cellulose acetate is preferably 58-60 and its intrinsic viscosity is preferably 1.7-1.9.  The composition may contain a stabilizer, such as an epoxy-type compound obtained by condensation of an epihalohydrin with a polyhydric phenol or an organic polyglycidyl compound prepared by the polymerization or condensation of glycidol.  In an example, 100 parts of cellulose acetate of acetyl value 58.4-59.6 and intrinsic viscosity 1.7 to 1.8 are mixed with 30 parts of di-isobutyl phthalate and 0.2 part of a polymeric condensation product of epichlorhydrin and bisphenol as stabilizer, dried at 160 DEG  F., extrusion compounded at 430-600 DEG  F., and reduced to moulding powder in known manner.  Shaped articles moulded from compositions of the invention have improved toughness and dimensional stability.

Title: Spring operated power unit
IPC: F16H33/06
Filed: 1936-06-29
Abstract: 477,580. Spring mechanism. TRELOAR, T. June 29, 1936, No. 17936. [Class 10] Mechanism for imparting rotary motion to a shaft 2 comprises a continuously-operated electric motor 8 serving repeatedly to stress springs 7 which are suddenly released in succession to impart, through rods 5, a series of high-pressure impulses to cranks 3 on the shaft 2. Each spring 7 is disposed between lower and upper plates 11, 21 slidable in a cylinder 6, the lower plate 11 carrying arms 12 which project through slots in the cylinder wall and are formed with hooks to engage over projections 14 on pivoted plates 15. The latter are shaped to provide inclined surfaces 18 for engagement by vertically slidable wedges 19 and are held by springs 16a in the position shown in Fig. 1 to maintain the lower plate 11 stationary during compression of the spring. This operation is effected by the motor 8 acting, through a speed-reduction gear 37, a system of links 36, 35, 34, 32, 29, and a plunger 24, to produce a step-by-step depression of the upper plate 21, pawl-and-ratchet devices 27, 28 being provided to maintain each step of compression. When the spring is fully compressed, a rod 51 carried by arms 50 pivoted in slots in the upper plate 21, projects below the lower plate 11 as shown in Fig. 4, so that, on the next upward movement of the crosshead 4 carrying the rod 5, it is forced upwardly, the arms 50 being in consequence actuated to depress the wedges 19 and thus move the plates 15 to release the lower plate 11. The spring is now free to expand and the plate 11 is projected downwardly to impart an impulse to the cross-head 4 and thus to the crank 3, the upper plate 21 being retained in position during this expansion by the pawl-and-ratchet devices 27, 28. The latter are disengaged, so as to permit the next upward stroke of the crosshead 4 to return the spring and all its associated parts to their initial position, by the engagement, when the plate 11 reaches its lowest position, of arms 13 carried thereby with nuts 82 on the lower ends of vertically movable rods 80. The pawls are reset by upward movement of the rods 80 effected by the engagement of the arms 13 with nuts 81. Reference has been directed by the Comptroller to Specifications 101,421, 167,790, 270,896, [all in Class 124], 348,518, and 356,588, [both in Group XXIII].
