Abstract: 1,144,426. Moulding meat or fish patties. HOLLYMATIC CORP. 12 Sept., 1967 [30 June, 1967], No. 41596/67. Heading B5A. [Also in Division F2] In apparatus for moulding patties of meat and fish wherein an apertured mould plate is attached to an element 22 for reciprocation between positions for receiving material from a hopper and for ejecting the pattie downwardly therefrom by a knockout member actuated by a cam 18, to form a stack on a support 48, an intermittently actuated pusher plate 47 is provided whereby stacks of adjustably predetermined size are successively displaced along support 48 from beneath the knockout member. The plate 47 is mounted on a bar 25 and is provided with a hinged lower end 49 whereby displacement of the initial pattie 12 of a succeeding stack is avoided upon retraction of the plate 47. The element 22 is reciprocated by a crank on cam 18 via a link 20 and lever 21, and the pusher bar 25 is intermittently forwardly displaced by a bar 24 on element 22 which engages beneath a pin 46 of a pivotal latch 31 which is normally biased downwardly out of the path of bar 24 by a spring 69 and is moved into the engaging position by an arm 42 mounted on a sprocket wheel 41 of an adjustable timing device mounted on the machine frame, whereby the number of patties in each stack to be engaged by the plate 47 may be set. The bar 25 is retracted by the engagement of a catch 67 thereon by bar 24. The sprocket 41 is mounted for rotation on a shaft 38 and is rotated in an anticlockwise direction, against a return spring 60, by the amount of one tooth for each reciprocation of the mould plate, by means of a dog 43 mounted on the link 20, and with reverse movement of the sprocket being prevented by the engagement between the sprockets of a lever 55, pivoted at 54 and biased by a spring 56. The lever 55 is pivoted out of engagement with sprocket 41 on forward movement of pusher bar 25 by the hooked end 62 of a release arm 61 attached to bar 25 whereupon the sprocket 41 is returned by the spring 60 to a position determined by the abutment of a stop-pin 59, fixed to the sprocket-wheel 41, with a stop-pin 58 on the shaft 38. The position of pin 58 is adjustably located by a knob 39 fixed to the shaft 38 and which may be located at increments, corresponding to the pitch of the sprocket teeth, by means of a spring latch engageable within apertures in a plate 37 of the machine frame whereby the number of patties in a stack to be engaged by the pusher plate 47 may be determined. The timing mechanism may be disengaged upon rotation of knob 39 to a position whereby a radially extending pin of shaft 38 displaces a lever 64, a projection 66 whereof displaces lever 55 out of engagement with the teeth of sprocket 41.

IPC: H04N9/455
Filed: 1970-09-01
Abstract: 1291906 Colour television FERNSEH GmbH 1 Sept 1970 [2 Sept 1969] 41881/70 Heading H4F The amplitude of a colour television signal derived by demodulation of a frequency modulated signal from a magnetic tape or disc is subject to long and short term deviations from the desired amplitude, the latter being periodic and due to variations in the force between the tape and head, and to variations between the heads, for example. Thus with a transverse track recorder having heads 1-4 wherein each head provides fifteen television lines before being switched at 13 to the next head; there will be a recurrent deviation with a period of 60 lines. In the apparatus described for reducing such deviations, the signals from heads 1-4 are demodulated 15, the colour sync. signal is gated 16, rectified 17 and its amplitude compared with a nominal value U in differential amplifiers 18, 24 to provide control signals. The control signal from 18 is switched at 19 (synchronously with switch 13) to low pass filters 20-23 with a time constant of 0.1 seconds which control respective amplitude and frequency response correcting circuits 9-12 in the paths of the four heads to reduce long term deviations. Signals from 24 corresponding to successive lines in each recurring set of 60 lines are passed via a resistor 25 to be distributed 26 to individual ones of 60 capacitors 27-86. A second switch 87 operates synchronously with switch 26 to sample the capacitors and provide a signal changing at line frequency, which controls a further amplitude and frequency response correcting circuit 14 for reducing the short term deviations. In the example given, the time constant of resistor 25 and each capacitor 27-86 was also 0.1 seconds, so that while the stored values on filters 20-23 each represent an average over 400 lines per head, those on capacitors 27-86 each represent 27 lines out of the 400 (i.e. 400/15) having the same track position and being scanned by the same head. The amplification given by amplifiers 18 and 24 was 100 and 20 respectively.

Title: Improvements in or relating to microwave devices
IPC: H03F7/04
Filed: 1961-11-29
Abstract: 1,006,325. Parametric amplifiers. WESTERN ELECTRIC CO. Inc. Nov. 29, 1961 [Dec. 12, 1960], No. 42789/61. Headings H3B and H3T. An amplifier or switch comprises a rectangular waveguide having a region of restricted cross-section which resonates with either a biased semi-conductor diode used as a non- linear capacitance or with a tunnel diode. As shown in Figs. 1 and 2, the restricted crosssection region is formed by a conductive wall 11 of depth l which extends across the waveguide 10 and provides an opening of height h. A point contact diode 24 contained in a quartz sleeve 23 terminated by end members 21, 22 is positioned in the restricted region, and is supported by spring fingers 28, 34 of chucks 26, 27. Lock caps 29, 23 retain the chucks in respective holes in the wall 11 and a sleeve 32, the upper chuck 27 being insulated from the waveguide by insulating bushings 31, 36 and conductively connected to a biasing source by a wire 35. As the end members 21, 22 of the diode assembly are positioned within the conductive boundaries of the waveguide, the fixed capacitance between these members is elimi nated. Apertures of length l and height h are provided in the waveguide walls at the region of restricted cross-section for branch waveguides 12, 14, both branches having tapered matching sections. The signal and pump frequencies are applied to waveguides 10 and 12 respectively, and the idler frequency branch 14 is adjustably short-circuited by a piston 16. Adjustment of the amplifier gain-bandwidth characteristic for optimum performance is achieved by rotating tuning screws 8 and 9. The waveguide sections are proportioned for dominant mode operation and the length l is chosen so as to resonate the region of reduced cross-section at the signal frequency and may be less than one quarter wavelength at the resonant frequency. In a modification, Fig. 6, tapering of the branch waveguides may be avoided by the use of a ramp 86. In a further modification, Fig. 5, the position of the region of restricted cross-section is adjustable. As shown, the diode 72 is supported by an apertured plate 70, and by loosening screws 64-68 the position of the aperture with respect to the waveguide 60 may be altered. Mention is made of the use of a tunnel diode as a negative resistance element, in which case the pump frequency is not required. When used as a switch, the transmission properties are changing by altering the diode bias so as to detune the region of reduced cross-section. Specification 899,253 is referred to.
