Title: Improvements in addressing and the like printing machines
IPC: B41L47/18
Filed: 1923-11-28
Abstract: 224,100. Marks, E. C. R., (Adrema Maschinenbau-Ges.). Nov. 28, 1923. Addressing and like machines. -An addressing or like printing machine of the kind in which the address plates e are fed along a slideway d one behind the other and in contact with each other by means of a reciprocating member c, is provided with a device for completing the feeding of the plates along the slide after the last plate has left the magazine f and the member c can no longer feed the plates, this device being inoperative until the last plate has left the magazine. The auxiliary feeding device consists of a bar l attached to the member c and adapted to slide in a groove m along one side of the slideway d, this bar carrying spring-pressed pawls o, p, q, r, the forward ends of which tend to spring upward but are normally prevented from so doing by the guide portions n of the address plates e and the cover plate s of the slideway. The pawls o, p, q are mounted on leaf springs. but the pawl r consists of a pivoted lever u, t<1> pressed downwardly at the end t<1> by a spring t. A plate w attached to the machine bed v prevents downward movement of the part t<1>, and therefore upward movement of the pawl part u, until the pawl is outside the magazine f, when movement is usually prevented by the guide portions n as described above. When, however, the last address plate has left the magazine, the pawl u can tilt upwardly behind it, and feed it and the plates in front of it, forward one step on the next reciprocation of the member c, the foremost plate falling into a receiver g. The next pawl q can now come into action and so on for all the pawls until the whole of the plates are in the receiver g. The last pawl o may be omitted, the last stencil being pushed by hand into the receiver. Spring-pressed levers y are situated in a groove in the side of the groove m, and press laterally against the plates e to keep them in correct position in the slideway.

Abstract: 781,306. Frequency-changing circuits; radio signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. July 13, 1955 [Oct. 20, 1954], No. 30177/54. Classes 40 (5) and 40 (6). A radio transmitter of the kind in which a transmitted carrier is derived by combining two locally generated oscillations comprises means for controlling the combiner in dependence upon the amplitude of one of the oscillations so as automatically to maintain the operating point on the substantially linear part of the characteristic. The Figure shows a combined radio receiver-transmitter in which the transmitted carrier is produced by mixing in the circuit 13, 14 the output of the receiver local oscillator 9 and an oscillator 11 operating at the intermediate frequency. The local oscillator 9 is of variable frequency and may comprise a number of crystals with frequency multipliers and accordingly the output voltage of the oscillator is variable. To maintain the mixer operating in its linear region a voltage developed across resistor 18 in the grid circuit of the receiver frequency changer valve 7 and derived from the local oscillator input is applied through rectifier 23 to the grids of the mixer. A fixed bias is also applied to the mixer through terminal 16 so that if the bias derived from the valve 7 falls below the fixed bias voltage the rectifier becomes non-conductive and the mixer bias is maintained at the fixed voltage level.

Abstract: 699,953. Lap-forming apparatus; stop motions. SACO-LOWELL SHOPS. Dec. 15, 1950 [April 13, 1950], No. 30612/50. Classes 120(i) and 120(ii) A machine for winding a lap of textile fibres into a compressed roll on a rotatable arbor comprises a pair of adjacent parallel rollers for frictionally rotating a lap on the arbor, fluid pressure means and connections capable of urging the arbor towards the rollers whereby to compress the lap, bearings, arranged to maintain pressure on each end of the arbor, and a mechanical connection between the two bearings arranged to maintain them at equal distances from the roller axes and consisting of a rack and pinion co-operating with each bearing and a shaft interconnecting the pinions.' As shown, the lap 16 is wound into a package 17 on a lap arbor 18 by means of rollers 12, 14 driven by gearing from a shaft 70 carrying a belt pulley. The ends of arbor 18 are loaded by bearings 28 on racks 30 engaging pinions fixed to a common shaft 36 so that as arbor 18 rises its axis remains parallel to those of rollers 12, 14. A further pinion 68 fixed to shaft 36 meshes with a rack 66 formed on the piston shaft 64 of a. compressed air cylinder 42, the ends of which are connected by pipes 50, 52 to a pressure pipe 58 via a four-way valve 54. During their upward movement, racks 30 are urged towards rollers 12, 14 by air pressure at the forward end 48 of cylinder 42. When package 17 has reached a desired size, meshing gears 78, 80, driven from shaft 70 through gears 74, 76, have moved 'to a position where hunting teeth 84, 86 engage to cause a pivoted arm 82 carrying gear 80 to swing so as to disengage a latch 90 and allow an arm 72, which is pivoted at 73 and which carries the bearing for one end of a shaft 70, to fall; this movement of arm 72 disengages gear 74 from gear 76, which drives the calender rolls delivering lap 16, and thus stops the calender rolls and breaks the lap, the broken end of lap being wound on package 17. Downward movement of arm 72 also acts through a link 92, foot lever 94, and bar 96 to operate the treadle 56 of valve 54 to connect the rear end 46 of cylinder 42 to air pressure and so positively elevate racks 30 and release the ends of arbor 18; the wound package can then be removed. To start a new lap package, foot lever 94 is depressed to raise arm 72 and re-engage gears 74, 76, arm 82 then swinging back to re-engage latch 90; lap 16 is then wrapped around arbor 18 on rollers 12, 14, and treadle 56 is operated to connect cylinder end 48 to air pressure and lower bearings 28 into pressure engagement with the arbor ends. Instead of operating through rack 66 and pinion 68, the air cylinder could be arranged to act directly on either the arbor bearings or the lap racks.

Abstract: Shelf-stable pulverulent foods are made from meats such as beef, pork, lamb, veal, fish and poultry are made in the manner of the parent Specification, the lean and fat portions of the meat being comminuted and rendered, and an antioxidant to prevent rancidification of the fat being incorporated while the fat is liquid.  The antioxidant is exemplified by nordihydroguairetic acid, butylated ethoxyphenol, butylated hydroxyanisole, butylated hydroxytoluene, propyl gallate and propyl gallate with citric acid; 0.001-0.1% may be added.  After the rendering, the fat portion may be converted to particulate form by atomizing the molten fat in cooled air, by spray drying an aqueous dispersion of the fat, by hydrogenating and then flaking the cooled, hydrogenated fat, or by the addition of particles of edible, fat-absorbing material, e.g. skim milk powder, cornflour, bran, puffed wheat, biscuit or breadcrumbs, of less than 2.5% moisture content, such an addition being made while the lean and fat are still together or after separation of the fat from the lean. Additional fat may be incorporated.  The flavour of the products may be enhanced by adding a commercial smoke flavour concentrate or smoked yeast.  Examples are concerned with making products from minced smoked bacon, comminuted cured and smoked beef mixed with tallow, communited cured and smoked lean pork trimmings and minced ham and bacon.  The products may be consumed as they are, or may be added to salads, salad dressings, eggs, sandwich spreads, cooked green beans, macaroni, spaghetti, soups or casserole or baked dishes.
