Title: Improvements in meat steaks such as fish and method of producing same
IPC: A23L13/00
Filed: 1930-02-15
Abstract: Meat steaks are produced by placing together a plurality of separate pieces of meat, preferably in the form of strips arranged in substantially parallel relation, binding them together by a surrounding wrapper to produce a unitary mass with the separate portions held against relative movement, and then cutting the mass into steaks by cuts transversely to the length of the mass.  The wrapper may be of vegetable parchment paper which, as it is wound from a roll, is formed into a trough by raising the edges.  The meat pieces are laid in the trough and the edges are then overlapped and stapled, stitched or otherwise fastened.  The paper is wetted at some stage of the wrapping to prevent the paper from subsequently becoming loose by stretching.  The wrapped product is preferably of oval section.  The wrapped meat may be frozen prior to cutting, in which case it is only necessary to overlap the edges of the wet paper to secure them together.  Freezing may, however, be effected after the cutting.  Alternative wrapping materials are sheets of regenerated cellulose, twine and fabrics. When fish steaks are being prepared, the adherence of the pieces to one another may be increased by treating them with a mild alkaline brine, or by allowing the pieces to dry slightly. Specification 311,317, [Class 49, Food &c.], is referred to.

Title: Colour television receiving apparatus
IPC: H04N9/22
Filed: 1946-02-21
Abstract: 620,137. Colour filters. SCOPHONY, Ltd. Feb. 21, 1946, No. 5508. Convention date, March 1, 1945. [Class 97 (i.)] [Also in Group XL (b)] In apparatus for producing colour images which includes means for producing successive black and white partial images representative of different colour values (e.g. television or motion picture apparatus), a device is provided for transmitting light the colour of which varies in correspondence with said partial images, said device comprising a pair of light polarising elements having between them a birefringent element and means for applying mechanical strain to said birefringent element to produce the required colour variation. As applied to a colour television receiver, successive black and white colour selection images produced on the fluorescent screen 11 of a cathode-ray tube 10 are viewed through an arrangement comprising two crossed polarizing sheets 12, 13 between which is supported a birefringent sheet 14 in such a manner that currents of different intensities applied to the electromagnet 23 and synchronized with the frame synchronizing signals in the device 26 produce different tensions in the sheet 14 thus producing variation in the colour transmission characteristic of the system 12, 14, 13. The sheet 14 and the tensioning currents may be selected such that the system operates as a three-colour (e.g. red, green, blue) filter, the same colour sequence being used at the transmitter. Instead of applying currents of different intensities to one magnet 23 a number -of magnets, Fig. 4 (not shown), may be employed each being supplied with a current of appropriate strength and suitably switched by electronic means. Alternatively a number of birefringent sheets each associated with a separate magnet may be used, Fig. 5 (not shown). When the birefringent sheet is made from a stiff but elastic material, such as glass, the deformation may be perpendicular to the sheet. This maybe achieved by clamping one edge of the sheet and successively deflecting the opposite edge to different degrees by means of a small cam, having a number of successive rises, and rotated synchronously with the colour frame signals applied to the cathode-ray tube, Fig. 7, (not shown). Alternatively, the perpendicular deflection may be applied by electromagnetic means. It is stated that the invention may be used for motion picture projectors.

Title: Improvements in wet spinning frames for flax and like fibres
IPC: D01H13/30
Filed: 1944-03-27
Abstract: 579,793. Ring spinning machines for flax &c. MACKIE & SONS, Ltd., J., and MACKIE, J. P. March 27, 1944, No. 5626. [Classes 120 (ii) and 120 (iii)] Flax &c. is wet spun on a machine comprising a stationary ring rail, the spindle rail having both pirning and builder motions applied to it, the spindles being driven, the rings being fixed and of the vertical type and furnished with ear-shaped travellers which move thereon. Flax from roving spools 10, mounted in a suitable creel, is led through a trough of hot water 15 to rollers 18, 19, where drawing is effected, and thence through a guide 20 to the traveller 21. The ring 22, carried by a bracket 27 provided with a drip-channel 28, is fixed, while the spindles 24 are driven by bands 25 from the tin roller. The line of the yarn from the nip of the draw rollers to the ring 21 is such as to reduce drag to a minimum. The pirning motion is produced by a heart-cam 45 rotated by a shaft 48 and gears 47, the cam effecting the oscillation of a lever 50 which, through a chain 54 oscillates a shaft 44 which, in turn, through a further chain 42 reciprocates the spindle rail 31, in a vertical direction, through carrier rods 32. A worm wheel 60 attached to the shaft 44 meshes with a worm 57 on a shaft 58 which carries a ratchet wheel 62, intermittently rotated by a pawl 63 as the pawl contacts a stop 65 during its oscillations, so to lower gradually the spindle rail 31 to produce building. A hand wheel fitted on the shaft 58 enables the builder mechanism to be raised, after the completion of a wind, to allow of doffing. The spindles are driven in groups of four, two on each side of the machine, the common driving band 25 passing around a tension pulley 71 supported by a slide 72 on a rail 73 and weighted at 74. It is stated that when spinning 80s line, the machine may operate at 7,000 r.p.m. and that a bobbin containing 50-100 per cent. more yarn than is usual may be obtained. It is further stated that the rovings 10 may be boiled, preliminarily, to improve the operation of the machine. Specifications 11,280/92, [Class 120], and 579,797 are referred to.

Title: Improvements in or relating to earth drilling equipment
Inventor: KNIGHTS RICHARD NORTHAM
IPC: E21B19/20
Filed: 1959-02-18
Abstract: 903,063. Boring earth. DOWTY ROTOL Ltd. Feb. 1, 1960 [Feb. 18, 1959], No. 5640/59. Class 85. Apparatus for pulling drill pipe strings comprises at least two endless-conveyer lift mechanisms each carrying means for engaging the pipe string and lifting it whilst a break-out mechanism operates, the drive to each of the conveyers being such that the speed of the conveyer during its laden upward movement is less than its speed during the necessarily longer unladen return movement. The platforms 10, 11 on the conveyers 3, 4 engage under the joints of the string and are used, in alternation, to lift the string, a break-out mechanism 12 moving up with the string and returning to engage the next joint, whilst the top pipe is spun off by a means 13. The platform 10 or 11 which has reached the top of its laden movement, must return around the pulleys 5, 7 or 6, 8 to take up the load by engaging the next but one joint. This return is speeded up by incorporating a ratchet connection between each of the pulleys 5, 6 and their shafts, which ratchet connection is over-run by motors 25, 26, of higher speed than the motor 22, which drive the conveyers during the unladen return movements. Means are provided whereby, when the load is taken by the platform 10 or 11, the corresponding motor 25, 26 is switched off, the drive of the conveyer during the laden lift being effected by the main motor 22. When the load is relieved from the platform 10 or 11, at the top of its laden lift, the motor 25 or 26 is switched on, and the high speed return is effected. The motors 25, 26 could be replaced by a single motor, the drive being applied alternately to the conveyers 3, 4 through a gearbox. The freewheel mechanism may be replaced by a gear-box, and one gear-box may serve for allowing the over-run and the alternate high-speed drive to the conveyers. The gearbox may be controlled by clutches, e.g. electromagnetic clutches. The apparatus may be operated in reverse to run a drill pipe string back into a borehole. Specification 875,127 is referred to.
Patent GB-564821-A (GB)
Title: Improvements in or relating to line amplifiers for high-frequency electric signals such as television signals
IPC: H03F3/44
Filed: 1943-04-09
Abstract: 564,821. Valve amplifying circuits; television. WHITE, E. L. C. April 9, 1943, No. 5690. [Classes 40 (iii) and 40 (v)] A line amplifier for television, adapted for feeding a plurality of loads (e.g. television receivers fed in parallel from a single input) comprises two valves with a common cathode impedance having the signals to be amplified applied to the control electrode of the first valve and to beat signals at the cathode of the second valve, the third valve being driven from the second valve and having a load in its cathode circuit. In such an amplifier, feed-back potentials are applied to the control electrode of the second valve in phase with the cathode potential, so that the third valve has a low output impedance. Fig. 1 shows a valve 1 to which the signal is applied having a cathode resistance 11 in common with a second valve 2 which amplifies a signal and feeds the main amplifier 3. The main amplifier may consist of an appropriate number of valves in parallel depending on the number of loads fed. The loads may consist of concentric lines 5 which may have series resistances inserted in them equal to the characteristic impedance of the section of line and matched at the-other end to the input of the device so that when the load is short-circuited the amplifier cannot consume more than twice the normal load. The negative feedback is taken from the output line 4 and may include a potentiometer 32, Fig. 3, which may be so adjusted that the output level in the cable 5 is the same as the input level. In addition, the feedback connection may include a network to correct for distortion in the input signals. To ensure that the potential of the output shall be positive for vision signals and negative to earth for synchronising signals, a resistance may be inserted between the output 4 and the high-tension supply; preferably, however, as shown in Fig. 3, further valves 20 are provided to furnish the negative signal. Such valves may be fed as shown from the anode of the main amplifier 3 or from the anode of the first valve, Fig. 2 (not shown). A diode 29 may be provided in shunt to the input to the valves 29 to reinsert the D.C. component. Fig. 4 shows a further arrangement in which the auxiliary valves 20 are energized from resistance 31 in the output circuit of the main amplifier 3. If the input capacities of the valves 3 and 20 are excessive due to the use of many valves in parallel, a cathode follower stage may be inserted in the inputs to these valves. The amplifiers may be duplicated if a balanced system is required in the output circuit.

Feb. 26, 1932, No. 5826. [Classes 38 (ii) and 38 (iv).] Multiphase current from a supply 1 is converted into single phase current of lower frequency in a load circuit 7 by means comprising grid-controlled valves 3 associated with a transformer 2 producing secondary phase voltages of such relative values that the pulsating unidirectional current appearing in the circuit 4, 5 has a wave form as indicated in Fig. 2. By means of grid-controlled valves 8, the half-waves of the pulsating current are alternately directed through opposite halves of the primary winding of an output transformer 6, thus producing A.C. of substantially sinusoidal form in the load circuit 7. The output transformer 6 may be dispensed with by using four valves 8 connected as indicated in Fig. 4 and controlled so as to cause half waves of the pulsating current to pass alternately in opposite directions through the load 7. In this case the use of a commutating condenser 9 is considered desirable. When the system is applied to traction, the valves 8 may be carried on a locomotive whilst the valves 3 are arranged at a fixed point on the supply system. Reference has been directed by the Comptroller to Specifications 165,985, 165,986, [both in Class 38 (ii), Electric currents, Converting &c.], and 388,771.

Abstract: 372,852. Multiplex signalling. COVENTRY AUTOMATIC TELEPHONES, Ltd. and LEY, D. A., of General Electric Co., Stoke, Coventry. Feb. 25, 1931, No. 5879. [Class 40 (v).] In a multiplex system employing a thermionic distributer, the number of valves required is reduced by division of the distributer into two parts. One of these scans the transmitters or receivers, arranged in groups each comprising K instruments, at the rate of N groups per second, while the other scans the same instruments, in a different grouping, at KN groups per second. Each distributer comprises, a set of valves D1 .. D4 or E1 .. E4, controlled by a source B or C of grid bias. The source B, for instance, emits waves of multiple frequencies, and these are superposed in groups, as described in Specification 302,180, [Class 40 (v), Wireless signalling &c.], so that four composite waves, each having a short peak at the appropriate instant and being individual to one of the valves, are so applied as to open each of the valves D1 .. D4 in turn at a rate of N complete cycles of operation per second. Similarly, a set of four composite waves from the oscillator C opens the valves E1 .. E4 in succession at the rate of KN operative cycles per second where K = 4 = N. The transmitter contacts W .. Z are so grouped that only one complete channel is open at a time from source G to line L. A similar arrangement may be used at the receiving station. Alternatively the connections may be rearranged so that valves D operate at KN and valve E at N groups per second.
