Title: Improvements in and relating to a device for energizing a time piece, including at least one photoelectric cell
IPC: G04C10/02
Filed: 1960-12-12
Abstract: 952,885. Clocks. BAUMGARTNER FRERES S. A. Dec. 12, 1960 [Dec. 18, 1959; May 17, 1960], No. 42610/60. Heading G3T. [Also in Division H4] A photo-electric cell which, in response to incident light supplies an energizing voltage for a time-piece (e.g. by charging a battery or driving a motor for winding a spring), is rotatably supported in an assembly comprising at least two further photo-electric cells termed "orientating cells", which provide energizing voltages in opposition for an electric motor coupled to the assembly the arrangement being such that light incident on either of the further cells causes the motor to rotate the assembly until the light incident on the cell which energizes the time piece is a maximum. Fig. 1 shows the general arrangement in which the "orientating cells" each comprise two separate photo-electric cells 33, 34 and 35, 36, the smaller cells 33, 35 (which have an area of one half or one quarter that of the larger cells 34, 36) serving to operate an electromagnetic switch 40 to either one of two positions depending on which of the cells receives the greater amount of light and so connect to the motor 39 either one of two condensers 41, 42 the charges in which are produced by the larger cells 34, 36 and which cause the motor to rotate the assembly in such direction that the photo-electric cell 32, which supplies driving energy to the time-piece 31, receives maximum light. To prevent the assembly from taking up a position in which the light is incident on the reverse side of cell 32 a stationary stop (not shown) is provided. Alternatively, the assembly may be formed as an isosceles triangle having the " orientating cells" as the two equal sides and the cell 32 as the base. Other constructional forms referred to are: forming the "orientating cells" as cylinder portions interconnected at one end; arranging all of the cells in the same plans so that, contrary to the arrangement of Fig. 1, the "orientating cells" would " seek" the light and; mounting the time-piece energizing cell so that it has two degrees of freedom. A practical realization of a table clock operating in accordance with the scheme of Fig. 1 is shown in Figs. 2 and 3. As shown, the clock 31 is supported on a frusto-conical casing 49 rotatably mounted on a base 48 the casing being provided with a plurality (18) of photo-electric cells comprising groups 32 to 36 equivalent to cells 32 to 36 of Fig. 1. The cells 32 are connected to the clock motor by electrical leads via one or more of the clock feet 50. The hand of the clock may be set by means of a wheel 51.

Abstract: 1357530 Feeding filaments or films COAL INDUSTRY (PATENTS) Ltd 13 Aug 1971 [8 Sept 1970] 42993/70 Heading D1F A method for the treatment of a continuous filament or film 2 in the presence of a fluid comprises passing the continuous filament or film through a tube 1, at least 1 metre long and having a bend in it, while passing a fluid through the tube in the direction of motion of and past the filament or film whereby the fluid imparts a tension to the filament or film, the filament or film contacting the wall of the tube at the bend and creating frictional forces in the filament or film. The internal configuration of the bend is smooth. The cross-sectional shape of the tube may be circular, elliptical, square or rectangular. The fluid is preferably a gas which may be inert to the material of the filaments or film or react therewith. The gas is preferably at superatmospheric pressure, and excess gas may be bled off at points intermediate the ends of the tube. The flow can be continuous or pulsating, and can be heated prior to entry into the tube. The tube itself may be positioned within a furnace or oven. The method finds particular application during any stage of the process of forming carbon fibres, filaments or films as described and claimed in Specification 1315940.

Abstract: 1,006,249. Measuring temperature electrically. ELECTRIC & MUSICAL INDUSTRIES Ltd. Dec. 14, 1961 [Dec.14, 1960], No. 43120/60. Heading G1N. [Also in Divisions G3 and H3]. In an arrangement for offsetting the change in frequency of a magnetron oscillator circuit (see Division H3), due to temperature change of its anode, by a compensating frequency change produced by a variation in its cathode current, the temperature change is determined by a thermistor in thermal contact with the anode. An astable multivibrator circuit 20 produces a square wave output signal which is limited in amplitude by a zener diode clipping circuit 21 and applied via blocking condenser 22 to the thermistor 23. The thermistor current develops a voltage across the base circuit of an emitter follower 25 and this supplies an output signal which is converted to D.C.by a synchronous clamp 26 and a filter circuit 27 and applied via emitter followers 28, 29 and a variable gain D.C. amplifier, comprising transistors 30, 31 and 32, to control that part of the magnetron cathode current passing through transistor 34.

Abstract: 1324306 Detecting underwater magnetic bodies; frequency analysis COMMISSARIAT A L'ENERGIE ATOMIQUE 17 Sept 1971 [18 Sept 1970] 43524/71 Headings G1N and G1U Apparatus for detecting submarines or underwater wrecks (which are regarded as magnetic dipoles) comprises a magnetometer on board an aircraft for detecting anomalies in the Earth's magnetic field, and an electronic circuit for analysing the output of the magnetometer including a plurality of band-pass filters connected in parallel and covering contiguous ranges dependent on the speed and height of the aircraft, means for analysing the outputs of the filters to determine which one has the largest output, and means for giving an indication when the largest output is within a frequency range consistent with an anomaly caused by a submarine or wreck. Theory is explained showing that for an aircraft flying at a speed of 100 metres/sec at a height between 100 and 400 metres, the significant frequency range is from 0À037Hz to 0À47Hz. As described the output S(t) of a nuclear magnetic resonance magnetometer is amplified and fed to eight band-pass filters PB1-PBN of equal Q, six of which cover the range from 0À037Hz to 0À47Hz, the other two having pass-bands immediately above and below this range respectively. Circuits DEI-DEN each form a histogrammic signal approximating the envelope of the output of the respective filter by full-wave rectification followed by gating successive peaks of the rectified waveform into a storage capacitor. Stages DMI-DMN then detect the maximum amplitudes of the respective envelope signals and circuit EC compares the outputs thus derived from neighbouring pairs of filters to see where the largest maximum is. If it is within the significant range covered by the inner six filters, an appropriate output is generated.

[Also in Divisions F3 and F4] Containers for substances developing gases under pressure e.g. the combustion chambers of liquid fuel rockets, have a casing wall 1 of laminated synthetic resin-bonded fibrous material of which one layer 3, whose fibres run longitudinally, is clamped to the head 6 of base 5 by ring-shaped members, 8 and 9 respectively, located within the container. The ring-shaped member 9 at the base end is of cap form and is connected to the base 5 by screws 13 such that the ends 3b of the fibres 3 which pass over and through the central aperture in the member 9, are clamped against the base 5. Similarly, the ring shaped member 8 at the head over which pass the ends 3a is form locked against the head 6 by means of nuts 11 on the screw threaded pins 10 spaced round the ring 8. Packings 14 and 15 prevent escape of high pressure gases. The outer and inner laminae have fibres running laterally. In a modification, Fig. 2 (not shown) the outer lamina is of plastic and is part of the outer casing of the container: the inner lamina is as in Fig. 1, but a further inner layer insulates the wall from the combustion heat. The ring 8 is replaced by a sleeve with a conical section recess taking the ends 3a of the fibres 3 which are secured there by a clamp ring, a nut holding the ring in the recess. A further nut screwing into the inner threaded surface of a cylindrical lug of the sleeve secures the head 6 to said sleeve.

Abstract: 1501228 Fluid-pressure servomotor systems GARDNER-DENVER CO 27 Oct 1975 [24 April 1975] 44118/75 Heading G3P A positive displacement rotary gas compressor 10 has an inlet valve 38 and a valve 48 to interrupt the flow of fluid from a discharge port 50 to a line 54 and to place said discharge port in communication with a chamber 42 when the compressor is unloaded in response to a rise in pressure in the line 54. A valve 86 communicates the rise in pressure to the valve 38 which progressively closes. At a predetermined pressure, a switch 88 closes to operate (a) a valve 82 allowing pressure from a line 77 to close the valve 38 fully and (b) a valve 74 to close paths 68, 76 through which liquid separated from the compressor output is cooled, filtered and returned. Pressure in chamber 42 now falls until a vacuum responsive switch 44 is operated to energize a pilot valve 78 controlling the valve 48 which connects the compressor output to the chamber 42. If an undue temperature rise occurs a thermally-responsive switch 94 operates valves 58, 74 and 82 so that the inlet valve 38 is again controlled by the valve 86 and the paths 68, 76 are re-opened. The valve 58 relieves pressure in the line 54 through a silencer 60 so that the valve 38 begins to open and the compressor resumes loaded operation, but with a lower pressure in the line 54. A second thermally responsive switch 96, operative at a higher temperature than the first, controls the supply to an electric motor 12 driving the compressor. In a modified system, closure of the liquid return path is adjustably delayed by a pneumatic device (112), Fig. 2, (not shown) to provide improved sealing and cooling of the compressor after the valve 38 has closed.
