In a cutter unit for shearing sheep or other animals comprising a casing housing drive transmission mechanism, and a stationary shear plate co-operating with a rotatable cutter disc, the shear plate is mounted adjacent to the casing and the cutter disc is located externally of the shear plate so that the face of the cutter disc comes into contact with the body of an animal during a cutting operation, and the body-contacting face of the cutter disc being adapted while in operation to smooth out the folds or puckers in the skin of the animal. The shear plate is a circular disc formed with edge teeth and the cutter disc has edge teeth projecting towards the shear plate. The cutter disc is driven through worm and gear teeth means housed in the casing. The shear plate is urged by springs against the cutter disc the face of which adapted to be in contact with the skin of an animal being sheared having a series of equi-spaced tangentially disposed ribs so arranged that as the cutter disc rotates they smooth the skin. The cutter unit may be secured to one end of the handle of a hand tool, the other end of the handle being connected to a motor either directly or through a flexible drive connection.

Title: Improvements in and relating to the recording of sound on films
IPC: G11B7/00
Filed: 1931-12-01
Abstract: 393,610. Recording sound optically. PETERSEN, A. C. G., 183, Norrebrogade, Copenhagen, POULSEN, A., 7, Hoyrups Alle, Hellerup, near Copenhagen, and BRITISH ACOUSTIC FILMS, Ltd., Film House, Wardour Street, London. Dec. 1, 1931, Nos. 33297 and 33298. [Class 40 (ii).] A variable width constant density record of sound is made in the form of two or more traces which are symmetrical about a longitudinal axis and have their zero or middle lines displaced from that axis, or an axis parallel thereto, proportionately to the volume of the sound recorded. Errors in reproduction due to background noise from excess of transparent portion of film and lack of accurate lateral adjustment of the film in relation to the slit are thereby reduced. Fig. 1 shows a recording apparatus for producing the record shown in Fig. 4. Light from source S is directed through triangular aperture b on to an oscillograph mirror m which reflects an image of the aperture on to a screen D having a slit d through which the beam passes to the film F. The beam is modulated by the sound to produce two wavy traces and is further modulated by a rectified component of the sound current so that the zero or mid lines of the traces are displaced from a longitudinal axis between the traces proportionately to the intensity of the sound as shown in Fig. 4. One of the modulating effects may be applied to movement of the mirror and the other to movement of the diaphragm B with the triangular aperture b or of the slit plate D or of a second mirror in the path of the beam. Alternatively, the whole modulation may be applied to movement of the oscillograph mirror. The apex of the triangular aperture may be replaced by a narrow parallel slit to avoid errors in the record when the apex is aligned with the slit. In a modification, the plate B is provided with two sideby-side triangular apertures and the record shown in Fig. 7 is then produced. Fig. 9 shows the record produced when the aperture is formed by three side-by-side triangular apertures. In this case, the outer apertures produce parallel records of the outer ends of the traces at their greatest amplitude. Specifications 377,675 and 380,850 are referred to.

Abstract: 1,177,424. Knitting-machines. BENTLEY MACHINE DEVELOPMENT CO. Ltd. 15 July, 1968 [22 July, 1967], No. 33820/67. Heading D1C. Following the raising of those selector instruments 4 by cams P1 . . . P6, one at each station, due to their remaining in a position projecting from their tricks after selection by selector cams SC, the selectors which have been depressed within their tricks by the selector cams SC are immediately reprojected prior to the raised selectors being returned to their original low level. Consequently the raised selectors on return to their original low level as well as the other selectors are in a projected position ready for immediate reselection by a further bank of selector cams at the next station. Selection between stations can be achieved over a shorter distance whereby more space, is available around the machine. The invention is described in connection with a six feeder machine in which pivotal selectors 4 having frangible butts are selectivelyactuated by selector cams SC. To enable the lower ends of those selectors which have been depressed to miss the raising cam to be projected outwardly the following portion of each cam P1 . . . P6 is recessed or relieved as at 8.

Title: Improvements in solid state image scanners
IPC: H04N5/369
Filed: 1970-07-13
Abstract: 1287205 Image scanner NIPPON ELECTRIC CO Ltd 13 July 1970 [29 July 1969 10 Sept 1969] 33849/70 Heading H4F [Also in Divisions G1 and G4] A random access solid state image scanner device comprises a linear array of field effect transistors Q 1 -Q 5  with their source electrodes connected via photodiodes P 1 -P 5  to a sawtooth source 12 and with different fixed voltages applied to their gate electrodes by means of equi-spaced tappings on resistor 15, these voltages being controllable by a signal source 17. The outputs from the drain electrodes of the transistors are coupled to differentiating circuit 14. The voltages at the tappings on resistor 15 are shown in Fig. 2 and the sawtooth waveform is shown in Fig. 3a. With V being the gate threshold voltage of each FET and with the control voltage from source 17 being such that the voltage at tapping 15c is zero, line 21, the transistors are sequentially turned-on and an output photocurrent as shown in Fig. 3(b) is obtained corresponding to the incident radiation on photodiodes P 1 -P 5 . Fig. 3(c) shows the time-differentiation of the photocurrent curve. If the control voltage is adjusted so that the voltages at the tappings of resistor 15 are as shown by line 22 in Fig. 2 then the effective scanning starts with transistor Q 2  since both Q 1  and Q 2  are in ON states at the start of the sawtooth wave. Thus by changing the control voltage, the scanning-starting point on the diode array can be controlled. The control voltage is synchronized 18 with the sawtooth wave. This is particularly useful in optical character recognition where the message may be printed on the left or right side of a document. The video output of the scanner may be fed back to control the signal source 17, Fig. 5 (not shown), so that the start of the scanning is controlled on the basis of the video signal. A plurality of such scanners each comprising an integrated circuit may be arranged side by side Fig. 6 (not shown).

Abstract: 977,689. Variable delay systems. WESTERN ELECTRIC CO. Inc. Aug. 29, 1963 [Sept. 11, 1962], No. 34168/63. Heading H4R. In a variable delay apparatus in which the delay is obtained by varying the frequency band of the signal applied to a dispersive delay line, i.e. a line in which the time delay is a function of frequency, the required delay is obtained in two similar ultrasonic delay lines 13 and 14, Fig. 1, the frequency band of the signal applied to the second line 14 being inverted with respect to the band applied to the first line 13 so that the phase distortion occasioned by the different delay applied to different components of the frequency band in the line 13 is cancelled by the complementary delay applied to the components in the second line 14. The inversion of the signal applied to the line 14 is conveniently provided by a modulator 17 fed with a carrier frequency twice that fed to the modulator 15 to bring the signal from source 11 to the frequency band appropriate to the delay required. The lower sideband of the output from modulator 17 is selected by a filter or by the characteristic of the delay line which may have a cut-off frequency in the required region.

Abstract: 1,100,011. Grinding glass. PILKINGTON BROS. Ltd., G. A. DICKINSON and T. S. COOK. 19 Aug., 1964 [29 Aug., 1963], No. 34259/63. Heading B3D. A method of imparting a substantially uniform surface to flat glass comprises advancing the glass in a predetermined path, subjecting one face of the glass to a surfacing operation and applying a pressure to the opposite face of the glass, which pressure can be varied at any section of a line transverse to the direction of advance of the glass so that it is more or less than the pressure applied at another section of the line to obtain a substantially uniform surface across the glass. As described, the glass 1 is advanced by drive rollers (not shown) over polishing blocks 2 consisting of felt pads, the blocks being arranged in two groups of three, each group being mounted on a rotatable spider. The glass, which is shown as thicker at its edges than at its centre, is pressed against the polishing blocks by a plurality of transverse lines of rollers 3. The ends of each roller are mounted in brackets 8 connected by struts 9 to hollow ribs 7 secured to the side members 5, 6 of a frame 4. Each strut 9 is vertically adjustable in its rib to vary the pressure of its roller relative to the pressure of other rollers in its line so that a substantially uniform surfacing action is effected across the width of the glass. The frame 4 is suspended by rods 10 from axles 13 having nose 14 for rotating the axles to lift the frame and rollers from the surface of the glass. The weight of the frame is counterbalanced by weights 17 and the lower position of the frame is determined by flanges 15 engaging stops 16. The frame is constrained to move in a vertical direction by guide members 21 associated with the corners 22 of the frame. The corresponding rollers in different lines may be of different lengths so that no part of the glass is unsupported during its entire travel past the surfacing blocks.

Title: Improvements in or relating to back-coupled, low-frequency tube oscillators
IPC: H03B5/10
Filed: 1946-11-21
Abstract: 619,111. Valve generating circuits. PHILIPS LAMPS, Ltd. Nov. 21, 1946, No. 34544. Convention date, June 18, 1943. [Class 40 (vi)] A low-frequency oscillator ir which the feedback voltage is connected by means of a capacitor to the grid-cathode circuit of the oscillator valve, is prevented from "squegging" by including in series with the capacitor, a resistor whose value is high compared with the grid-cathode impedance of the valve. The Figure shows a tunable Hartley oscillator circuit in which if the amplitude of oscillations produced in the circuit 3, 5 tends to increase, resistor 11 prevents grid current flowing. The grid-bias of the circuit thus remains constant, and over-oscillation is prevented by the decrease in the effective mutualconductance of the valve. The invention is of particular application in wide-range lowfrequency oscillators for testing purposes or in musical instruments.
