Title: Plastic materials
IPC: B65D1/26
Filed: 1964-04-10
Abstract: Thermoplastic resin articles having a foamed structure only on a surface thereof may be prepared by steeping a shaped product of the thermoplastic resin in a medium absorbable by the resin, removing the shaped product from the medium when the medium has been absorbed in depth in a surface thereof, and thereafter heating the shaped product to convert that part of the product which has absorbed said medium to a foamed condition.  Suitable thermoplastic resins are polystyrene, styrene-butadiene-acrylonitrile graft and/or mechanical polyblends, other rubber modified graft and mechanically blended styrene polymers, vinyl-chloride-vinylacetate copolymers, polyethylene which may be chlorosulphonated or chlorinated, ethylenevinyl acetate copolymers which are graft and/or mechanically blended with polyvinyl chloride homopolymers and copolymers, polyvinyl halide homopolymers and copolymers. The medium absorbable by the resin may be a solvent or a mixture of solvents and nonsolvents for the resin.  Suitable solvents are trichlorofluoromethane, methylene chloride, acetone, dichloroethylene, xylenes, carbon tetrachloride methyl ethyl ketone, benzene, toluene and chloroform and suitable non-solvents are methanol, ethanol, n-pentane, isopentane, hexane and diethylethylene. The steeping process may also be carried out by subjecting an article to solvent vapours in a vessel which may be pressurized.  If desired, the article first formed may be reshaped during the process.

Title: Improvements in or relating to electronic control circuits
Inventor: NUTTALL THOMAS CAYTON
IPC: H03K3/04
Filed: 1954-05-24
Abstract: 779,881. Multi-stable state circuits CINEMA-TELEVISION, Ltd. May 24,1955 [May 24, 1954], No. 15211/54. Class 40(6) A signal control circuit comprises an electric discharge tube in which the control grid is connected to a constant potential through a circuit of which the impedance is not negligible, signals to be controlled being applied to said grid and in which the operating conditions of the tube are changed by signals applied to the cathode and in which the grid is connected through a capacitance to a point of which the potential varies oppositely to the variation in potential of the cathode so that the change in the grid potential resulting from a change in cathode potentials is reduced. The Figure (Complete) shows a gating circuit in which signals applied at input terminals 23, 24 are obtained sequentially at the common output 26 by means of control signals applied to the cathodes at 27, 28. When for example a negative pulse is applied to terminal 27 to render tube 21 conducting a positive pulse is simultaneously applied at the terminal 28 to cut off tube 22. Any change in grid potential which would be occasioned by the cathode gating voltage is off-set by applying simultaneously to the screen grid from the opposite cathode a voltage opposite to that at the tubes cathode so that the current flowing in the inter electrode capacities is reduced substantially to zero. The capacity between the screen grid and control grid of each valve is augmented by the external capacitors 29, 30 to such a value that the total change in potential at the control grid due to a change in potential at the cathode is eliminated. The Figure (Provisional) shows the application to a high speed counter circuit of the type described in Specification 779,882 in which tubes 1 and 2 are normally conducting and tubes 3 and 4 cut off and in which positive pulses applied at terminal 5 and negative pulses applied at terminal 6 cause the pattern of conductivity to be changed. When for example a positive pulse is applied to the cathode of tube 1 from terminal 5 it is also simultaneously applied to the screen grid of tube 3 and a negative pulse is applied at terminal 6 to the cathode of tube 3 in this wav anv change in the control grid notential which would be occasioned by a change in potential at its respective cathode is off-set by the voltage applied from the other tube to the screen grid. The capacitors 17-20 augment the inter-electrode capacities so that the total effect at the control grid of a change of cathode potential is negligible.

Title: Improvements in and relating to electric fans
IPC: F04D25/10
Filed: 1950-06-20
Abstract: 693,920. Screw fans. GENERAL ELECTRIC CO., Ltd., and CURTIS, T. J. June 13, 1951 [June 20, 1950], No. 15411/50. Class 110(i) In an oscillating electric fan in which the oscillating mechanism includes a frictional engagement which slips when the fan meets an obstruction, the frictional engagement is applied between a member secured to the fan base and a member which forms an abutment for the oscillating mechanism, whereby the slippage between the members displaces the arc of oscillation so as to avoid the obstruction. The fan housing 10 is oscillated about a spigot 44 by a mechanism comprising a crank wheel 28 driven through gearing 23 by the fan motor 12 and coupled by a connecting rod 31 to an abutment disc 62. Disc 62 is held stationary relative to the spigot 44 by a sleeve 51 which acts through a thrust bearing 60 and a spring washer 61 to press it against a disc 65 fixed to the spigot. If the fan meets an obstruction, slippage can occur between the discs 62, 65 to prevent damage to the fan. To stop the oscillation, sleeve 51 is moved downwards by turning a pin 52 having an eccentric portion 53 which engages a recess in the sleeve. This frees the disc 62, and the sleeve 51 now bears against a friction member 57, which may be of cork, rubber or spring metal, so as to lock the fan housing 10 relative to the spigot 44. Spigot 44 is carried by a member 43 which is pivoted at 42 to a base 40 and can be secured in several alternative angular positions by a ball-detent and a locking screw. According to the Provisional Specification, the fan blades may be as described in Specification 682,094.

Title: Automatic electronic apparatus for measuring the bronchial resistance and the elastance of the pulmona tissue
IPC: A61B5/087
Filed: 1975-04-16
Abstract: 1504596 Measuring bronchial resistance and elastance of the pulmona tissue SORAM SA 16 April 1975 [8 May 1974] 15646/75 Heading G1N Part (E) In a device for automatically measuring and displaying the resistance of air-flow (R) through the bronchial tracks, and, the elastance (E) of the pulmonary tissue, an endovenous catheter in the central venous system is used to determine the endothoracic pressure together with a pneumotachygraph device to determine the air-flow through the patients mouth. Alternatively, the air-flow or volume signal may be produced directly by measurement of deep thoracic impedance. The device  comprises two channels, one receiving a pressure signal the other receiving an air-flow signal. Each channel has a preamplifier 4 or 9, a device for correcting for slow drift 5 or 28 and a differential amplifier 7 or 25. Each differential amplifier receives the signals from its own channel and a signal from the "other" channel which is first multiplied by a feedback signal (X or B proportional to the instantaneous values of R or E). The difference between the inputs to each differential amplifier 7 or 25 is compared in phase by a phase detector 13 or 100 whose output feeds a memorizing interpreting device 14 or 200 and a display control device 51. The value of R or E is usually passed through the display control device 51 unless the phase relationship between the two channels changes radically. In this case, the signal is prevented from passing through and the signal retained in the memory is fed to the corresponding display device. A warning light 57 is also triggered, indicating that only memorized valves are being displayed.

Abstract: 559,930. Embossing machines ; ink-ribbon mechanism. RIPLEY, G. H. Nov. 6, 1942, No. 15710. [Classes 100 (ii) and 100 (iv)] An embossing-machine which is adapted to reproduce the effects obtained by hand-tooling on leather is constructed with an embossing roller 8a which can be readily secured to a holder 8 on a rod 7 which is depressed into printing position by a cam operated by a lever 13 to bring the roller 8a into operative position with the work which is secured by means of adjustable gauges 43b, 44, Fig. 6, to a worktray 25 which can slide on guides 24a, 24b on a table 22. A counter-roller 16 is driven either by hand or by means of a motor 20, which is adapted to be de-energized by the action of a projection 30 on the tray upon a contact 32. The roller 8a is driven frictionally from the roller 16, which is covered with rubber and is arranged below an aperture 26 in the table so that it engages the work-tray. The pressure of the roller is controlled by a screw 15 which effects relative adjustment between the rod 7 and a tube 6 which slides in a head 5 carried by an arm 3 adjustably secured to an upright rod 2 on a base 1. The roller 8a is normally raised out of action by a spring 10 acting on a collar 11 on the rod 7. The roller 16 is mounted in a bearing 17 on the base 1, and the roller 8a may be heated by a burner supplied by a gas tube 41, or by an electric heater. The embossing foil is fed from a roller 37a and wound upon a roller 37b of slightly greater diameter so as to keep the foil taut, and guide rollers 38a, 386 carried by supports 39a, 39b cause the foil to move substantially tangential to the roller 8a. The rollers 37a, 37b are geared together by means of pulleys 36a, Fig. 1, and 36b Fig. 3 (not shown), which are connected by a slack belt to permit of slip.
