Title: Improvements in or relating to meat tendering apparatus
IPC: A22C9/00
Filed: 1936-08-31
Abstract: 480,763. Tendering meat. DIETZ, J. P. M., and BAKER, D. T. Aug. 31, 1936, No. 23840. [Class 28 (ii)] In a meat-tenderer, the cutting- unit is carried by an arm 6 which is pivotally mounted between collars 3, 4 on a standard 1 so that it may be swung to bring the cutters over different parts of the meat. The cutting- unit is carried by a plunger 8 slidable in a guide 7 in the arm 6 and raised and lowered by a hand-lever 12 connected to the arm 6 by a link 13. A plate 15 is arranged around an extension 14 of the guide 7 and is retained by a collar 16 secured to the extension, and a pair of springs 17 are housed in telescopic casings 18 with their opposite ends anchored to the knife holder 9 and to the tops of upper members 18 which are carried by the plate 15. The knives 10 pass through a guiding and stripping grid comprising two comb-like members arranged in interdigitated manner, each member having a plate 20 whereby it is secured to the grid holder 19. The holder 19 is carried by a pair of arms 23 pivoted thereto at 24, the arms being urged inwardly into grooves in the knife holder 9 and the plate 15 by springs 25 secured to the plate 15, or by springs arranged around the pivots 24. The arms 23 are formed with ratchet teeth 26 which engage the bottoms 27 of the grooves in the plate 15 to lock the grid relatively to the plate. The arms 23 are maintained out of contact with the groove bottoms by rollers 28, carried by the knife holder 9, engaging cam surfaces 29 on the arms. When the meat is placed on the slidable base board 38, the cutter unit is raised and the arms 23 are held disengaged by the rollers 28. When the lever 12 is depressed, the knives and grid descend together until the grid rests upon the meat. The grid is then stopped whilst the descent of the knives, through the grid and into the meat, continues, the rollers 28 travelling over the cams 29 so that the arms 23 swing inwards into locking engagement with the groove bottoms 27. The handle is then released to allow the springs 17 to raise the knives, the grid remaining locked until the rollers 28, once more, disengage the arms 23, the grid being then raised by the knife holder 9 contacting with stops 30 on the arms 23. To ensure that the grid holder always remains horizontal, the two ends of the holder are connected by links 33, 34 to a common shaft 31, vertical movement of one end of the grid thus effecting corresponding movement of the other end. The grid is further guided by rods 36 which work in guides in the knife holder. The knife holder may be mounted for rotational adjustment on the plunger 8, the plate 15 likewise being rotatable. Specification 480,764 is referred to.

Title: Improvements in or relating to ammonia masers
Inventor: BOUD WILLIAM EDWARD
IPC: H01S1/06
Filed: 1959-07-14
Abstract: 921,780. Masers. GLASS DEVELOPMENTS Ltd. Feb. 24, 1960 [July 14, 1959], No. 24195/59. Class 40 (9). In an ammonia maser, liquid nitrogen or liquid oxygen is used to cool a reservoir to condense solid ammonia from the gaseous phase. The reservoir is electrically heated to supply ammonia to the main envelope of the maser at a vapour pressure dependent upon the temperature. The reservoir comprises a cylinder 45, Fig. 3, brazed to the top plate 32 of the main envelope 30 of the maser. The top of the cylinder is closed by a bulb-shaped cap 50 which serves as a receptacle for liquid nitrogen. The reservoir may be heated by a heater coil 49 on a metallic former 47. Ammonia molecules find their way into the main envelope through a collimator 56 comprising a single tube or a plurality of tubes in an aperture 57 in the top plate 32. The reservoir is thermally insulated by a cover 58. When ammonia molecules in the higher energy state leave the collimator they are focused into a resonant cavity 42 by parallel rods 35 arranged in a cylindrical array and maintained alternately at ground potential and at 20 kv. Ammonia molecules in the lower energy state drift away from the axes of the cylinder. The electrical output from the resonant cavity is collected by a waveguide 44. The rods 35 are spaced by two rings 36 each having a quatrefoil aperture therein so as to interconnect only alternate rods. The highvoltage rods are carried by insulation 38 on the top plate 32 and on a support plate 39. The low-voltage rods are fixed directly on the plates 32, 39. The maser envelope stands in liquid nitrogen in a Dewar flask 59. A modified ammonia reservoir 60, Fig. 4, of copper is mounted on a mild steel rod 64 integral with a disc 65 forming the base of a container with a cylindrical wall 67 of brass. The container stands in liquid nitrogen 69 in a Dewar flask 68. The reservoir 60 is connected to a source of ammonia and to the collimator by tubes 62, 70 and 62, 71. The reservoir 60 may be heated by coil 63 to vaporize the ammonia. Collimator.-The collimator may comprise a single tube or may be formed by winding alternate smooth and crinkled metal foils upon a mandrel. In the collimator shown in Fig. 5, a mild steel member 78 with grooves 79 is press fitted into a mild steel tube 75 of circular section. Prior art.-The Specification acknowledges an arrangement comprising a cylinder and liquid ammonia connected to the collimator through a number of pressure-reducing valves and reservoirs in series. Charging the maser with ammonia.-The maser is connected to a source of ammonia and the reservoir is cooled to collect solid ammonia. The maser envelope is then sealed. The reservoir is warmed to operate the maser. When the reservoir is exhausted the envelope is warmed and the reservoir is cooled to recharge it.

Abstract: 1,006,090. Frequency and phase modulation. WAR DEPARTMENT SECRETARY OF STATE. June 26, 1963 [June 27, 1962], No. 24762/62. Drawings to Specification. Heading H3R. [Also in Division H2] Transistors or diodes are series or cascade connected and shunted each by a capacitor to form a phase-shift network which, when a modulation input is applied to the transistors or diodes to vary all their resistances in unison, correspondingly varies the phase of a carrier also supplied to the network input. Alternatively the phase shift network may be in the feed-back circuit of an oscillator generating the carrier, so that frequency modulation is produced. A variable D.C. bias in series with the modulation varies the mean frequency. The oscillator amplifier, e.g. a transistor, may be replaced by a current amplifying transformer feeding back to the network input, if the phase shifting series transistors produce sufficient power gain.
