Abstract: 1,196,755. Fluid pulse generators. HENRIKSEN & HENRIKSEN I/S. Oct. 26, 1967 [Oct.27, 1966], No.48684/67. Heading G3H. A fluid pulse generator comprises a cylinder 1 and a free piston 2 having a reduced portion 5 which permits a pulse of fluid to be communicated via inlet 3 and outlet 4 each time the piston moves from one end of the cylinder to the other under the control of fluid admitted to the cylinder ends alternatively by electromagnet valves 6, 7. The speed of the piston and hence the pulse duration, is controlled by the pressure of the fluid and the degree of throttling effected by the de-energized valve 6 or 7 which is opened to exhaust the air compressed in the associated end of the cylinder by the piston. In a modification Fig. 2 (not shown) the piston has three reduced portions each adapted to coact, simultaneously, with inlets and outlets in three parallel paths. The Specification also describes an arrangement Fig.3 (not shown) in which three separate parallel connected pulse generators are in circuit with a variable timing control circuit which enables pulses to be emitted a predetermined time after the initiating signal has been produced.

Abstract: 1461277 Depth measuring devices for divers E T SKINNER & CO Ltd 14 Jan 1975 [19 Oct 1973 15 Nov 1973] 48888/73 and 53101/73 Heading G1A In an electronic device for use by a diver for measuring the depth, or variations in depth of a dive, a pressure sensitive diaphragm 2 is connected to a pair of crossed diffraction gratings 4 so that relative movement causes a magnified movement in the MoirÚ fringes formed by the gratings 4. The gratings are illuminated by a lamp 5 and the relative movement of the MoirÚ fringes is sensed by two photo-cells 6 and 7. The output of one or the other of the photo-cells is fed to an "up-down" counter 8 in dependence on a condition sensing device (not shown) which examines the MoirÚ fringes to determine the relative movement and to tell if the depth is being increased or decreased. Thus the counter 8 is caused to count up or down in dependence upon the depth variations. The accumulated count is converted into a binary coded decimal by a readout device 9 which supplies an accumulating register 10 that supplies a display logic circuit 11 feeding a light emitting diode display 12. The components 8-11 are part of a greater integrated circuit powered by batteries 14 and supplied with pulses from an oscillator 15 to represent the passage of time. A key board 16 can be used to actuate an algorithm built into the circuit to cause the display to indicate the depth, or time underwater, or a function of the depth and the time. In a further embodiment Fig. 2 (not shown) a shift register is used instead of the accumulating register 10, thereby storing the data indicative of the variations in depth with the time. After the dive, the apparatus may then be plugged into a readout device which can operate a pen recorder to produce a graph of the depth of dive plotted against time.

Abstract: 1,075,488. Microphones. SIEMENS A.G. Dec. 8, 1964 [Dec. 9, 1963], No. 49836/64. Heading H4J. [Also in Divisions G1 and H1] An electromechanical transducer comprises a needle mounted to exert a varying pressure upon a surface of a semi-conductor body at a point on a first region of a first conductivity type close to a rectifying junction between said first region and a second region of the opposite conductivity type that together form a semiconductor diode and in which said second region extends to form the collector region of a transistor having a base region of said first conductivity type and an emitter region of said opposite conductivity type, said base region being ohmically connected to said first region. A carrier plate 1 having an electrode 2, has two P-type regions 4 and 5 embedded in an N-type region 3 which form a rectifying diode and part of a NPN transistor respectively. The P-type base 5 has an, N-type emitter 6 embedded therein with an electrode 7 thereon. A layer 9 of SiO 2 , covers the device except for two small portions where an ohmic contact is made between transistor base 5 and region 4 by strip 8 formed by vapour deposition. A sapphire stylus 10 acts upon the rectifying diode. In another embodiment (Fig. 4, not shown) the stylus 10 rests in a hollow in the insulating layer 9, immediately above or near to a point where the PN junction is perpendicular to the surface of the device, whilst the ohmic eonnection is provided by a wire. In an alternative embodiment (Fig. 5, not shown) the base and P-type regions are ohmically connected by continuous semi-conductor material which provides both the base and the P-type regions whilst the stylus rests in a hollow in the P-type region through a perforated insulating region. The transducer may be used in a pressuremeasuring device or detector or in microphones. A PNP transistor may be used in place of the NPN transistor with a corresponding change to the diode.

Abstract: 1524356 Television RCA CORPORATION 24 Oct 1975 [18 Nov 1974] 49925/74 Heading H4F In a disc record playback e.g. of the capacitive type, the recovered FM composite colour video signal encoded in a "buried subcarrier" format is demodulated 30, 40, 50, comb filtered 160, 240, 260, 250 and de-emphasized 300 before the deflection sync component of the composite colour video signal is separate 340 therefrom. A defect detector 60 controls switch 80 to pass the demodulated composite signal of the one line period delayed 160 composite signal to amplitude modulator 90 which modulates the amplitude of carrier waves from VCO 100 with the signals delivered from the switch 80. The frequency of the carrier waves developed by VCO 100 vary in accordance with the signal jitter produced during playback and thus the output at modulator 90 is jitter compensated. A burst gate 120 is enabled by pulses derived 360 from the separated sync 340 to pass bursts from notch filter 110 to a phase detector 130 which also receives the subcarrier reference frequency from an oscillator 140. Delay line 160 and subtractive combiner 170 effects chrominance comb filtering and the resulting filtered 180 chrominance component is fed to adder 320 for output use. The luminance component fed to adder 320 is derived from delay line 160 via amplitude detector 190 and filter 200 to a phase splitter 230 poled such that its additive combination with the output of delay 250 (compensating delay for filter 200) provides a comb filtering action. The output from adder 280 comprises the luminance components (and sync components) free of the buried subcarrier chrominance component. The output of the de-emphasis circuit 300 is D.C. restored in keyed clamp circuit 310 before being fed to adder 320. A squelch control signal is also fed to adder 320 from generator 330. A detailed circuit of sync separator 340, clamp keying pulse generator 350 and burst gating pulse generator 360 is described with reference to Fig. 2 (not shown).

In a spinning-frame, all the spindles are driven by a continuous shaft, while the drafting-rollers are driven by a shaft which is discontinuous. By thus subdividing the drafting- roller shaft, each segment can be made short enough not to be twisted when the frame is started, thereby avoiding back-rotation of the rollers when the frame is stopped, and the consequent occurrence of thick and thin places in the yarn. Accordingly no limitation is imposed on the number of spindles comprised in the frame. As shown, the spindles of a ring- frame are driven from a continuous shaft 19. The shafts for the driven rollers of the front and back pairs of drafting rollers are each divided into two segments: thus there are two segments at the left hand end of the frame which are driven together by a chain 21<SP>1</SP>, while the two at the right hand end are driven by a chain 21. When more than two segments are provided, the intermediate segments are also driven from the shaft 19.

Abstract: The device contains a rotor (5) which rotates in a housing (1) about a horizontal axis (2) and is fitted with tearing tools (4). At the distance (a) away from the impact circle (14) of the tearing tools there is a first anvil edge (26) which is part of a pressing wall (20). The pressing wall (20) lies in a plane which runs through the axis of the rotor and is inclined with respect to the vertical plane by 0 to 25 DEG . When comminuting cardboard boxes and large areas of cardboard difficulties often arise because these materials have the tendency to build up above the rotor in a vault-like shape at the side walls of the housing chamber and to form a bridge of material as a result of which the supply to the rotor is blocked. In order to destroy these material bridges, the pressing wall (20) can be pivoted between the position shown and a horizontal position, a second anvil edge (27) protruding, in the horizontal position of the pressing wall, as far as the aforesaid distance (a) towards the impact circle (14) of the tearing tools (4). <IMAGE>
