Title: Moulding apparatus and method
Inventor: STEVENS DONALD EARL
IPC: B29C31/04
Filed: 1965-06-19
Abstract: 1,115,366. Injection moulding. KOHLERJOA CORPORATION. 19 June, 1965, No. 26034/65. Heading B5A. Partly cured polystyrene &c. beads are injected into a mould 10, 20 by means of an aspirating device 56 through which air is forced so as to draw the beads from a reservoir 64 through a pipe 62. Air under pressure is also supplied to the reservoir 64 through a pipe 80 and valve 83 to assist the delivery of beads therefrom. When the mould cavity is filled, excess beads are returned by the air jet to the reservoir. The mould cavity is then closed by an hydraulic plunger 40. The moulded article may be cured and then cooled by steam and water respectively admitted to chambers 8, 22 through supply pipes 12, 14. If the mould parts are porous, removal of the article may be assisted by air pressure. The valve 83 and a valve 84 in the supply to the aspirator nozzle (54), Fig. 2 (not shown), may be operated by electric, mechanical or manual means. Closing of the mould part 10 is by a ram 4.

Title: Improvements in or relating to Battery-Powered Muscle Stimulators
IPC: A61N1/36
Filed: 1968-05-31
Abstract: 1,187,314. Muscle stimulators. DYNATONE ELECTRONICS CORP. 31 May, 1968 [9 June, 1967], No. 26162/68. Heading A5R. [Also in Division H3] In a battery powered muscle stimulator control means 20 provides control signals to an electrical switch means 25 coupled to a blocking oscillator 44 so as alternatively to render the switch means in one state in which the switch means inhibits pulse generation by the blocking oscillator and another state in which the switch means causes repetitive pulse generation by the blocking oscillator and an output circuit 60 is provided for amplifying and steepening the leading edges of the output pulses from the blocking oscillator 44, and the output circuit 60 includes a self biassing amplifier 64 which is only rendered capable of amplifying on receipt of a pulse signal from the blocking oscillator. The control signals are obtained from a transistor multivibrator 21 operating at 30 c/s. This turns gating transistor 26 ON and OFF cyclically. When the transistor 26 is ON this allows the blocking oscillator transistor 46 to become conductive and start to oscillate at 60 c/s. The transistor 46 normally being non-conductive due to the biassing network 52, 63 and 56 and OFF state of transistor 26. The output from the blocking oscillator is passed by voltage stepdown transformer 62 to turn ON normally non- conductive transistors 64, 68. The output from these transistors is passed via a voltage step up transformer 72 to output electrodes 73a, 73b which may be of brass. The output circuit amplifies and shapes the output pulses, the derivative action of the transformer inductances providing steep wavefronts. The output voltage may be varied from 60 volts down to allow for individual differences in the sensitivity of facial muscles by a variable resistor associated with the ON-OFF switch 74. A resistor 75 acts as a safety measure when the resistance associated with switch 74 is shorted.

Abstract: 1,164,748. Detecting passage of sheets electrically. NORFIN, Inc. June 4, 1968 [June 5, 1967], No.26533/68. Heading G1N. [Also in Division G4] The presence, thickness or grade of sheets of non-conductive material, e.g. paper, is detected by feeding the sheets between the plates of a capacitor 42 forming part of a series resonant circuit 40 connected to the output of an H.F. oscillator 10. The circuit is arranged to be in resonance in the absence of a sheet so that under these conditions the signal at its input is zero. In the presence of a sheet, causing an increase in the reactance of the circuit, the input to the resonant circuit increases in dependence on the thickness and/or grade of the sheet. The signal at the input to the circuit 40 is fed to circuit 60 where it is rectified and doubled and hence fed to the gate of an SCR91 whose trigger voltage is regulated by adjusting the tapping point of resistor 72. The system may be used for counting the number of sheets passing through the capcitor, to detect two or more sheets passing simultaneously, e.g. in a sheet collator, or to monitor the thickenss or grades of individual sheets, the device 100, operated by the triggering of the SCR being a counter, reject machanism or sorting mechanism respectively.

[Class 80 (ii).] Variable-speed gearing comprises discs 7, 8 mounted side by side which rotate with cyclically varying speeds in alternating phase so that the faster-moving one drives through one-way balls 14 a hollow drum 12. This cyclic variation is caused by the relative eccentricity of a driving-shaft 6 which carries slotted arms 2, 3 engaged by pins 4, 5 extending from the discs 7, 8. The pin 5 from the farther disc 8 passes freely through a slot 9 in the nearer disc 7. To vary the speed of the driven drum 12, this eccentricity is varied. In the form shown, the shaft 6 is fixed in position and the drum 12 is loose upon a stub shaft 11 supported in a bracket arm 16 which is pivoted about an ultimately-driven shaft 19 and adjustable by thumb nuts 23 so as to carry the drum 12 across the end of the shaft 6.

Filed: 1950-11-03
Abstract: The invention comprises m-allyloxy-phenyl isothiocyanate and its production from m-allyloxy-aniline by conversion of the amino group into an isothiocyanate group.  Methods exemplified are (1) conversion into m-allyloxyphenyl dithiocarbamate with caustic alkali, ammonia or tertiary base and carbon disulphide; treatment of the dithiocarbamate with phosgene or ethyl chloroformate gives the isothiocyanate, in the latter case via an intermediate; (2) reaction with thiophosgene in water or inert solvent.  Other methods are (3) as in (1), decomposing the dithiocarbamate with a heavy metal salt; (4) reaction with carbon disulphide to give di-(m-allyloxyphenyl)-thiourea, followed by treatment with a mineral acid, acetic anhydride or acetyl chloride; (5) conversion to thiourea as in (4), splitting off hydrogen sulphide (e.g. with mercury oxide) to give carbo-di-(m-allyloxyphenyl)-imide and heating the latter with carbon disulphide; (6) reaction with phosgene yielding m-allyloxyphenyl isocyanate which is treated with phosphorus pentasulphide or else heated to produce the di-imide of (5); (7) treatment with chloroform and alkali, giving m-allyloxyphenyl isocyanide and addition of sulphur; (8) diazotization and reaction with copper potassium thiocyanate to form m-allyloxyphenyl thiocyanate which rearranges on heating. m-Allyloxy-aniline is made by allylation of m-nitrophenol or m-acetaminophenol and reduction or hydrolysis.
