Title: Electric system for operating a gas discharge lamp
IPC: H05B41/392
Filed: 1970-02-24
Abstract: 1299523 Discharge lamp circuits BERKEY PHOTO Inc 24 Feb 1970 [21 April 1969] 8697/70 Heading H2H A circuit for operating a gas discharge lamp V1 comprises a triac SR1 connected in series with the lamp across an A.C. source the impedance of which forms the sole ballast, a control circuit for switching on the triac at a variable phase angle and a circuit for initially igniting the lamp at a variable phase angle corresponding to the variable phase angle at which the triac is switched. To initially ignite the lamp, a switch S1 is temporarily closed thereby charging a capacitor C2 via a resistance R7 and the source. After a time determined by the setting of a ganged resistor R8 a triac SR2 is triggered so that the capacitor C2 discharges and supplies a high voltage pulse to a transformer T1 to start the lamp. The triac SR1 is simultanously triggered and maintains the lamp on as it is switched on in each half cycle of the source voltage. The triac SR1 may be replaced by a pair of controlled rectifiers.

Title: Apparatus for preparing and dispensing beverages from prefabricated cartridges and a liquid
Inventor: STASSE ROLAND
IPC: H01J29/41
Filed: 1964-03-02
Abstract: 1,051,012. Coffee and like brewing apparatus. R. STASSE. March 2, 1964 [March 4, 1963], No. 8784/64. Heading A4D. Apparatus for brewing tea, coffee or the like comprises an upper body 1 with a nozzle communicating through a cock 2 with at least one pipe line for supplying liquid to the apparatus and a perforator 5, and a lower body constituting a cartridge holder 3 with an orifice in its lower end larger than a coaxial orifice formed in the cartridge 4. As shown in Fig. 1, a cartridge 4, of thin pressed metal sheet or plastic, is placed in the holder 3 with an inner perforated disc 7 upon which the tea leaves, coffee grounds or the like, are placed and covered by a lid 6. The upper body 1 is then lowered by links 12 until the perforator 5 perforates the lid 6, and a spring- loaded device 18 locks the two bodies together. The liquid is allowed to pass through holes 5a in the hollow perforator 5 into the cartridge 4 and the beverage flows out through the disc 7 into a receptacle. Alternatively, the upper body is fixed (Fig. 3, not shown) and the cartridge holder 103 is raised by a pivoting arm 106 which carries a knife 108 to sever the end of the cartridge 4 to form an orifice. An ejector 109 is provided to force the used cartridges 4 out of the cartridge holder 103. In an electrically operated apparatus (Fig. 4, not shown), a loaded cartridge holder 303 is pushed to the left thereby cutting a nipple 4f from the cartridge by a fixed cutter 308 and depressing a switch 315. This closes the energizing circuit of an electro-magnet 304 and a solenoid-operated valve 302 which thrusts plunger 305b downwardly and operates the lock mechanism 318 and the liquid supply. On breaking the circuit, by pulling the cartridge holder to the right, the used cartridge 4 is lifted out of the holder as plunger 305b is retracted, and released from the lock mechanism 318 to be dropped on to a deflector 301e and into a disposal bin. Alternatively, an independent cartridge holder 3 with a handle may be secured to a fixed upper body 1 by a bayonet coupling, Fig. 5, (not shown). The disc 7 may be provided with perforations of varying shapes and sizes depending on the beverage being made.

Title: Improvements in motor or tractor ploughs
IPC: A01B61/04
Filed: 1929-03-19
Abstract: 309,579. Aktiebolaget Ofverums Bruk. April 13, 1928, [Convention date]. Tools, mounting yieldingly.-In a motor plough in which a pivoted plough body is held in operative position by a spring controlled lever which allows it to swing backwards upon encountering an obstacle sufficient to overcome the action of the spring, the spring actuates a headed rod which acts directly on the lever without being mechanically connected with it, and the contact surface between the rod and lever is adapted to relieve the lever from the action of the spring after a very slight compression of the spring, so as to permit of the use of a powerful spring capable of securing a steady motion of the plough body irrespective of varying resistance of the ground, The arm or short beam 2 carrying the plough body 3 is pivoted at 4 on a bracket 6 on the plough frame 1. The free end of the arm 2 is held between an adjustable stop 21 on the frame 1 and a roller 17 carried by a bell-crank lever 16 pivoted at 15. A rod 7 is slidably mounted in the bracket 6 and a second bracket 14, movement being limited by a bolt 8 passing through a slot 9. A strong spring 10 surrounds the rod 7 and bears against the bracket 6 and a forked head 11 on the rod. A roller 13 mounted in the head 11 normally bears against the rear edge of the lever 16, the upper end of which lever forms a cam 19 having a part forming a cylindrical surface, concentric with the pivot 15. Backward movement of the plough body 3 about the pivot 4 depresses the roller 17 and turns the lever 16 about its pivot 15 against the action of the spring 10 until the roller 13 runs on to the cylindrical part of the. cam 19 and thus releases the lever 16 and plough body 3 from the control of the spring 10 and allows them to swing freely. The plough body may be returned to its operative position by driving the implement backwards, engagement with the ground causing it to swing about its pivot 4. The end of the arm 2 strikes a projecting pin 20 on the lever 16 and thus turns it into locking position.

Title: Improvements in or relating to the pressing of food material
IPC: A22C7/00
Filed: 1966-03-01
Abstract: 1,106,300. Pressing bacon &c. into slabs. SWIFT & CO. 1 March, 1966 [2 March, 1965], No. 8858/66, Heading A2U. In a method and an apparatus for pressing a roughly rectangular slab of food, particularly bacon, to produce a more precisely rectangular slab suitable for slicing, the rough slab is fed into a pressing chamber the size of which is reduced, to compress the slab, in three directions disposed at right angles to each other. The compressed slab is then allowed partially to expand within the chamber accompanied by corresponding expansion of the chamber in at least one of said directions. The slab is again compressed in one of said directions, and compression is then stopped, and the more precisely formed rectangular slab is ejected from the chamber in one of said directions. In the apparatus Shown in Fig 5, the pressing chamber is defined by: a fixed, horizontal base 11, a vertical side 12, i.e. a gate 32, movable only vertically, up and down, by a hydraulic device (not shown); a<SP> </SP>vertical side 14 movable laterally, towards or away from the side 12, by a hydraulic device 80, and also movable longitudinally with end 13 mentioned below, an end 15, i.e. a gate 48, movable vertically up and down by a hydraulic device (not shown) and also movable laterally, to and fro, with the side 14, an end 13 movable longitudinally, to and fro, by a hydraulic device 70, and a top 16, 108 movable vertically, up and down, by an upper yoke 109, which is actuated by a hydraulic device, and is connected to the top by devices 120-130, so that the top 16 can move laterally with the side 14, and longitudinally with the end 13. The end 15 is raised and the side 12 is lowered, and a rough slab of food is inserted into the pressing chamber. The side 12 is then raised and the abovementioned pressing and expanding operations are effected by hydraulic rams and devices operating in a hydraulic system described and illustrated with reference to Figs. 6A and 6B (not shown) and controlled by an electric circuit described and illustrated with reference to Fig. 7 (not shown). The end or gate 15 is then lowered, and the more precisely formed rectangular slab is ejected from the chamber, by an ejector (78) actuated by a hydraulic device (77), Fig. 6B (not shown).
Patent GB-811688-A (GB)
Title: Method for purification of glutamic acid
IPC: B01J47/00
Filed: 1957-03-19
Abstract: Glutamic acid is separated and concentrated from an aqueous liquid also containing other amino acids by passing the liquid through a column packed with a strongly acidic cation exchange resin and through a column packed with an anion exchange resin, treating the glutamic acid-rich fraction so obtained with a weakly basic anion exchange resin, and eluting the glutamic acid adsorbed on the resin with an acid solution.  The first two resins may be used in any order, or together as a mixture; when the liquid contains a high proportion of glutamic acid as compared with other amino acids, it is preferable to pass it through a mixture of the first two resins. Suitable starting solutions are Steffen's waste and a fermented broth.  Suitable strongly acidic cation exchange resins are "Amberlite" IR-120, Dowex 50, Chempro C-20, "Permutit" Q and Diaion SK 1; suitable anion exchange resins are "Amberlite" IRA-400, "Amberlite" IR-4B, "Amberlite" IR-45, Dowex 1, Duolite A-42 and Diaion SK 100; suitable weakly basic anion exchange resins are "Amberlite" IR-4B and "Amberlite" IR-45 ("Amberlite" and "Permutit" are Registered Trade Marks).  The liquid is passed through the first resin to obtain a glutamic acid-rich fraction of the effluent, which is passed through the second resin to obtain a more concentrated glutamic acid-rich fraction (or the liquid is passed through the mixture of the first two resins to obtain a single concentrated fraction), and the latter passed through the third resin.  The adsorbed glutamic acid may then be eluted with 1-5 n NCl, and crystallized out by adjusting the pH to 3.2.  The overall concentration is about 10 : 1.  Examples of the process are given.
