Abstract: 928,622. Reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. June 13, 1961 [June 13, 1960], No. 21300/61. Class 39 (4). In a swimming-pool type of reactor, the water is contained in a metal tank which is supported inside a concrete tank. The annular space between the metal and concrete is filled with sand. As shown, the metal tank 1 is carried on girders 3 set across the base of concrete tank 5 and supported on concrete shoulders 7, 8 and pillars 9. Bulkheads 11 extend between 5 and 1 and spaced between them may be emptied to facilitate experimental work near the reactor, additional protection being then provided by the lead blocks 15. Pipe lines 16 are led to the reactor through openings 10.

Filed: 1956-07-12
Abstract: 813,131. Nuclear fuel elements. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. July 3, 1957 [July 12, 1956], No. 21543/56. Drawings to Specification. Class 39(4). In a fast nuclear fuel element, of the type described in Specification 778,881, the outer protective tubular sheath carries a series of bands each of which consists of a set of helical fins. The fins of adjacent elements contact each other and bowing of the elements and the formation of hot-spots, due to heating, is reduced as the helical fins permit the flow of coolant past the bands.

Title: Improvements in and relating to dough-cutting and like machines
IPC: A21C5/00
Filed: 1928-07-26
Abstract: 314,246. Paterson, J. C., and Baker Perkins, Ltd. July 26, 1928. Directing and adjustably supporting endless-belt conveyers. - An endless-belt conveyer, used in connection with a dough-cutting and rolling machine, runs over rollers 24, 26 carried by a table 23 and can be raised or lowered about the pivots 27, by means of the screw jack 37. The blocks carrying the pivots can be locked in various positions in the slots in which they are fitted, thus enabling the belt to be moved bodily so that the receiving end is adjusted nearer to or further from the dough rollers. Tensioning screws 33 take up the slack of the belt after adjustments. The fixed driving-pulley 25 is driven by belt toothed and chain gear 39, 136, 138 enclosed in a flat-topped gear-case 43, Modifications mentioned include the provision of a separate pivoted flap at the receiving end of the conveyer, the pivoting of the whole conveyer about the axis of the driving pulley 25, and the effecting of horizontal adjustment by moving the conveyer and frame 29 bodily instead of the belt-carrying frame.

Filed: 1972-05-10
Abstract: 1395816 Treating metals against corrosion M B PERLMAN 10 May 1972 [10 May 1971] 21876/72 Heading B2E A process of treating ferrous metal e.g. rolled mild steel, Zn, Al, Cu or Ag to improve their resistance to chemical attack, comprises bringing the surfaces into contact with an acidic composition consisting of a colloidal dispersion of silica and a water soluble sugar and removing the metal surface from contact with the composition before any visible SiO 2  deposit is formed. The composition may include 0.0004% SiO 2  and a surfactant e.g. saponin. The treated surface may be painted with oil-modified alkyd, or electrodeposited with brass, Cd or Cr, and the treatment may be carried out after painting or plating to treat remaining exposed metal surface. The sugar may be glucose or fructose derived from beet sugar or blackstrap molasses. The composition may also include, in solution, gallic, succinic, aspartic, salicylic, malic or citric acids, succinamide, glycine or E.D.T.A. The preferred method of treatment is by dipping.

Title: Brushless synchronous dynamo-electric machines
IPC: H02P25/02
Filed: 1972-05-10
Abstract: 1396784 A.C. machines with D.C. excitation; control of A.C. motors LAURENCE SCOTT & ELECTROMOTORS Ltd D M PAYNE I SWAN and K W G BURCHAM 10 May 1972 21901/72 Headings H2A and H2J  In a brushless synchronous dynamo-electric machine, e.g. a motor, as shown, or a generator, wherein in operation the field winding 14 is energized by a field supply circuit comprising rectifying means, e.g. a bridge 12 and an A.C. exciter winding 11 across which the bridge is connected the field winding, bridge, and exciter winding being mounted for rotation with the rotor of the machine and power being supplied to the exciter winding by rotation in a stationary exciter field, the field supply circuit comprises a field control circuit 18 mounted for rotation with the rotor and semi-conductor switching means, e.g. a thyristor 13 in the path between the exciter winding and the field winding, and the control circuit is responsive to a voltage generated on the rotor independently of the field winding and having a frequency which is proportional to the rotor speed to render the thyristor conducting in dependence on the frequency of the voltage thereby to connect the exciter winding to the field winding when the rotor speed exceeds a predetermined value. This voltage is derived, via a transformer 31 and a bridge rectifier 32, from a part of the exciter winding 11, and is created by a pulse shaping circuit formed by resistors 33, 35 and a Zener diode 34 whose rectangular output pulses are proportional in length to the period of the exciter voltage which as the motor speeds up become shorter until at a predetermined speed, depending on the setting of a variable resistor 53, will fail to charge a capacitor 38 to a level sufficient to initiate a discharge through a PUT 37; above this predetermined speed pulses are developed across a resistor 42 which renders conducting a transistor 55 which in turn renders conducting a transistor 57 whereby a charge on a capacitor 47 develops a series of pulses across a resistor 59 to render conducting the thyristor 13; the motor will now pull into synchronism. Field winding shunting resistors 22, 23 progressively limit the field slip voltage during initial starting, and in Fig. 2 a further stage of shunting resistor (60) is added, whilst in Fig. 3 the resistor 23 is replaced by a resistor (71) shunting the thyristor 13, and an oppositely poled field shunting thyristor (72). In Fig. 4 the supply to the motor stator winding is monitored by a current transformer (81) whose rectified output is added to an independent supply to a stator exciter winding (15). The pulse shaping circuit may be replaced by a transistor switch/Zener diode combination.

Abstract: 922,271. Dehairing hides and skins. ROHM & HAAS G.m.b.H. June 23, 1960, No. 22002/60. Class 76. Hides and skins are dehaired by successive treatment with water and pulverulent or pasty proteolytic enzyme products and then with sulphur-containing compounds having a reducing action. The enzyme may be proteases formed by micro-organisms and bacteria, or pancreatic tryptase, and #-glucosidase may also be added. The sulphur compounds may be sulphites, bisulphites, thiosulphates, dithionites, and thioglycollates, of which the sodium salts are preferred; or sodium sulphide or sodium hydrosulphide. They are preferably used in the presence of 30-50% of water. When a painting process is used a thickening agent such as kaolin may also be added. Cationic or non-ionic wetting agents such as ethylene oxide condensation products having 6-16 oxide units may be added to the enzymes, and non-ionic or anionic wetting agents may be added to the sulphur compounds. In examples, goat, kid and calf skins and cow hides are dehaired and in some of the solutions ammonium sulphate is also added. Specification 776,323 is referred to.

Abstract: 617,434. Fuel-injection pumps. GENERAL MOTORS CORPORATION. July 25, 1946, No. 22146. Convention date, Aug. 17, 1945. [Class 102 (i)] A fuel-injection pump comprises a cylinder 1 provided with a plunger 5 reciprocable in a bore 3, a pumping space 14, an annular filter element 15, and a check valve 21 held on its seat 11 by a spring 23 located between the valve and a spray nozzle 7. The plunger 5 is formed with a pressure relief groove 51 communicating with a slot 55, such that on its working stroke the plunger first closes the fuel inlet port 27 by the edge 53, then closes the drain port 29 by the inclined edge 56 of the slot 55 and at the end of the injection simultaneously opens both ports by the circumferential edge 57 of the groove 51, which causes a relief of pressure in the pumping space 14 through the ports 27 and 29, thereby allowing the quick re-seating of the check valve 21 to prevent any dribbling of fuel through the spray opening 25 in the nozzle 7. A spring 31 which returns the plunger 5 on its filling stroke, is retained and supported on a flange 37 of a plunger control sleeve 39 slidably mounted on the plunger. A control arm 47 integral with the flange 37 is adapted to rotate the plunger by manual control means or a governor to vary the amount of fuel injected by the pump.
