Title: Method of substantially reducing the consumption of arc electrodes
Inventor: HANNAPPEL GUNTHER
IPC: H05B7/02
Filed: 1961-04-24
Abstract: 996, 259. Automatic control systems. KNAPSACK GRIESHEIM A.G. April 24, 1961, No. 14796/61. Heading G3R. A method for at least substantially reducing the consumption of carbon or cooled metal are electrodes, used for example in furnaces, comprises introducing into the neighbourhood of the electrodes an automatically controlled amount of carbon and/or an organic compound, whereby carbon is deposited on the electrodes in an amount and location corresponding to the amount of electrode material consumed in operation. Fig. 1 shows an arc furnace for three phase current in which the amount of a hydrocarbon supplied automatically regulated in dependency on the electrode consumption via the arc voltage. The voltage between the electrode 1 and the star-point 2, which voltage is proportional to the arc voltage, is conducted via a voltage dependent switch 3 to the coil 4 of a magnet valve 5 which opens when the coil 4 is excited and thus, above a limit voltage, allows a hydrocarbon gas to flow through conduit 6 and through annular space 7 along the electrode 1 on which carbon is deposited in the arc zone 8. Fig. 2 shows a three phase current furnace in which the organic compound and/or carbon is supplied through bores 12,13 arranged coaxially and eccentrically in electrodes 14. Optical devices are used for controlling the distance a between the electrodes which can be kept constant. Electro-optical scanning devices are referred to for controlling the carbon deposition.

Title: Reduction of antigen hypersensitivity
IPC: A61K39/36
Filed: 1962-04-17
Abstract: An injectable pollen antigen composition capable of being administered to sensitive humans without inducing hypersensitivity p of the type caused by a pollen antigen-antibody complex in humans, comprises an injectable pollen antigen composition of an aqueous suspension of pollen antigen particles comprising antigens contained in a non-irritating and non-toxic spongy mass, said spongy mass being formed by the reaction of (a) a protein containing material which is a cytoplasmic protein, gelatin, casein or globulin; and (b) an acidic component which is deoxyribonucleic acid, ribonucleic acid, thymine, thymidylic acid, sialic acid, glycoprotein, glycoside, heparin or gum ghatti; said spongy mass providing protective means for the pollen antigens whereby the formation of toxic complexes with antibody in the circulating blood serum is prevented, said protected pollen antigens being capable of being picked up from the blood serum by the cells of the reticulo endothelial system, the protected pollen antigens picked up by said cells being capable of inducing high levels of antibody which are released into the circulating blood serum.  In one example, a ragweed pollen extract, haemoglobin, deoxyribon nucleic acid and sodium chloride solution of pH 4.8 is incubated at 37 DEG  C. for 18 hours.  In a similar example, the D.N.A. solution is replaced by heparin solution.  Pollens from timothy, rye, May and June grass may also be used.

Title: Improvements in valves and valve gear for fluid pressure engines
IPC: F01B17/00
Filed: 1960-04-28
Abstract: 899,869. Engines valve-gear. GENDREAU, J. C. April 28, 1960 [May 27, 1959], No. 14890/60. Class 122 (2). Means for distributing pressure fluid for the control of a reciprocating engine comprises a primary slide valve 13, Fig. 5, having outlet ports 17, 18 connected respectively with the opposite ends of a cylinder 26, Fig. 3, containing the operating piston 25 of a secondary slide valve in the form of a four-valve system consisting of two chambers 54, 55, each of which is in communication at its middle parts with one chamber of the engine cylinder and carries at its ends two seats 38, 39 and 41, 42 communicating respectively with the source of fluid under pressure and exhaust. The primary valve 13 consists of a piston sliding in a cylinder 12 and moved alternately to opposite end positions when the engine piston reaches opposite ends of its stroke by the action of a rod 4 moving with the engine piston. The piston 13 has through channels 16 so that pressure fluid admitted through an inlet 15 can pass, according to the position of the piston, through either of the ports 17, 18 to ports 21, 22 in the cylinder 26. The valves 36, 37 are carried on rods 43, 44 which are screwed into a common sleeve 45 and arranged to slide jointly with the pistonrod 31 of the piston 25 by reason of connectors 48. The chambers 54, 55 are respectively connectable by the passages 56, 57 with the lower and upper ends of the main engine cylinder, and, depending upon the position of the valves 36, 37, pressure fluid from the main inlet 51 can pass to either of the chambers 54, 55 through gaps formed between the sleeve 45 and the rods 43, 44. With the valves in the position shown in Figs. 3 and 5, the main engine piston is assumed to be moving downwardly. When this piston reaches the lower end of the stroke the operating rod 4, Fig. 5, moves the piston 13 downwards in the cylinder 12 and so pressure fluid from the inlet 15 passes through the ports 18, 22 instead of through the ports 17, 21. As a result, the piston 25 moves leftwards and so the valves 36, 37 seat on their seats 38, 42 to cause a reversal of the fluid flow to and from the engine cylinder. Adjustment of the valves 36, 37 may be effected by arranging for the seats 38, 41 to be carried by screw-threaded parts.

Filed: 1973-03-28
Abstract: 1397866 Measuring rotary unbalance electrically CARL SCHENCK AG 28 March 1973 [28 March 1972] 14931/73 Heading G1N The rotary unbalance of a wheel 4 Fig. 1 is determined from the sinusoidal motion of the wheel 4 and mounting 3, which also carries the drive motor 5 and is supported between springs 2. The oscillatory displacements are fed by a rigid coupling 6 to two displacement transducers 7, 8. The transducer 7 is coupled to the member 6 at such a point 12 as defined, that its output signal is stated to be due to the static unbalance of the wheel only, whereas the signal from the other transducer 8 is due to both static and dynamic unbalance. These signals are combined in known manner to determine the unbalance compensation required at the wheel rim on either side El, E2 of the tyre. The angular position of the unbalance is determined using a stroboscope.

Filed: 1957-05-13
Abstract: 848,961. Electroluminescence. GENERAL ELECTRIC CO. May 13, 1957 [May 15, 1956(3)], No. 15106/57. Class 39(1). [Also in Groups XXXVI and XL(c)] An amplifying device, Fig. 1a, comprises the combination of an electro-luminescent cell 5 and a photo-conductor 3. A light-transmitting electrode of titanium or tin oxide, or thin aluminium or silver 2 is applied to a glass, quartz or mica transparent insulator 1. The photo-conducting light permeable layer 3 is sprayed, sputtered or evaporated on to the electrode 2 and may comprise the sulphides, selenides, or tellurides of cadmium, lead or zinc. A further electrode 4 similar to electrode 2 is applied to the layer 3 followed by an electroluminescent phosphor such as zinc sulphide activated by copper and dispersed in a transparent dielectric where the device is A.C. operated. If operation is required at either D.C. or A.C. a layer of zinc sulphide and copper in a continuous crystalline layer or a single crystal phosphor may be used. The material may be deposited by spraying a light-transmitting dielectric such as nitrocellulose or alkyd resin in which the powdered phosphor is dispersed, or a vapour reaction technique may be employed. A further electrode 6 which may be a point or line contact and is similar to electrodes 2 or 4 is applied to the upper surface of layer 5. In a modification, Fig. 2, a slab 100 of glass or mica is arranged with the photo-conducting layer 3 mounted above it with two sets of interleaved electrodes 2, 2a. On the lower side of the slab 100 a light transmitting electrode 4 is mounted with the electro-luminescent layer 5 below and a further conducting layer 6, which may be similar to layer 4 or made reflecting to increase the efficiency of the device. An outer insulating case 14 may be employed and if transparent the electrode 6 is also made light permeable. Windows may be provided, Figs. 25 and 27 (not shown) to allow a light output from either a light or electrical input. Circuits employing the device are described, (see Group XL(c)).

Title: Improvements in telephone or like systems
IPC: H04Q3/00
Filed: 1942-10-30
Abstract: 561,155. Automatic and semi-automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., GILLINGS, C., and BEALE, C. E. Oct. 30, 1942, No. 15236. Drawings to Specification. [Class 40 (iv)] In a system employing voice-frequency signalling over junctions, each numerical digit is represented by a code of two impulses each comprising not more than two frequencies out of a possible four. This arrangement is advantageous when the available power to be divided between the receiving circuits for the individual frequencies is limited. The system is in other respects similar to that described in Specification 560,794, in which a seizing signal of frequency X is employed and each numerical code signal comprising not more than three out of four frequencies W ... Z is preceded by a preliminary signal or prefix of all four frequencies which serves to check their correct reception. In order to retain this advantage, the digits 1-5 are represented by a prefix of frequencies W, Y followed by an impulse of one or two of those frequencies and of frequency X which has already been used for the seizing signal, while the digits 6-0<1> are represented by a prefix of frequencies W, Z followed by an impulse of one or two of those frequencies and of frequency X. The relay that controls the transmission of the prefix in the latter case also serves to increase the interdigital pause in the manner described in Specifications 559,016, and 560,794. In the incoming relay set, the two relays that respond to the different prefixes connect up alternative marking wipers of the sending switch. An alternative code which does not possess the advantage mentioned above employs two frequencies for each digit with different two-frequency prefixes for the groups 1-5 and 6-0 as before.

Filed: 1920-06-08
Abstract: 144,660. Siemens - Schuckertwerke. Dec. 14, 1917, [Convention date]. Dynamos, regulating; motors, controlling. - To obtain a regularly repeated peripheral current and field distribution for both pole-numbers in a variable-pole polyphase machine having a twolayer drum winding, the winding is formed of coils of equal width s which has a value lying between the greater pole pitch T and the smaller pole-pitch i. The sum of the ratios of coil width to pole pitch for the two pole numbers is equal to 2. For example, for a ratio of pole-numbers of 1:2, the coil-width s may be made equal to twothirds of the greater pole-pitch, and for a ratio of pole-numbers of 2: 3, a coil-width of four-fifths of the greater pole-pitch mav be chosen. Fig. 5 shows a two-phase winding of 24 coils adapted to be connected for four and six poles respectively; the winding zone of each phase for one pole-number consists of a number of coils A &c. or a &c. equal numerically to the number of pairs of poles of the other pole-number. In switching over from one pole-number to the other, groups of three coils each are combined in one circuit, making only eight circuits to be changed over; one such coil-group is shown in thick lines. Diagrams showing three-phase windings for other ratios of pole-members are given in the Specification. The different circuits of the windings may be connected in series, parallel, star, or mesh.

Abstract: 448,297. Toys. WHITEHOUSE, F. R. B., Fairdays, Barlows Road, Edgbaston, and CHAD VALLEY CO., Ltd., Chad Valley Works, Harborne, both in Birmingham. May 29, 1935, No. 15588. [Class 132 (iii)] A walking toy horse comprises a part 10 pivoted on a pin 13 disposed between two metal plates 12 secured to the part 11. The legs 15 on the part 10 are fixed to a base 16 and the legs 19 on the part 11 are fixed to a base 20 convex on its underside. Forward motion of the toy is effected by pulling and releasing the cord or chain 21 secured to the part 10 to pivot the part 10 with respect to the part 11, rearward motion of the toy being prevented by roughening the base 20 or by covering it wholly or partly with non-slipping material 22 such as sandpaper or plain or pimpled rubber sheet. The weight of the part 10 is arranged well forward as by loading the front or disposing the legs well forward. A stop 24 to the hinge is provided to prevent too great relative movement of the parts. In a modified form, the rear part of the horse does not touch the ground but is attached to a cart 26, Fig. 7, which may be built up in plywood of side pieces, cross pieces and floor, or may be moulded in one piece of synthetic resin or other material. The side members 32 extend down as shown and have holes with ample clearance for the axle carrying the wheels 35 which are outside the side members. As the front part rises on being pulled by the string 21, the cart moves back to bring brakes 36 on the side members against the wheels, which are preferably shod with rubber or non- slip material. Thus there is no movement of the cart as a whole backwards. Alternatively, the cart may have a spring to engage the ground when it is tilted, or a ratchet wheel secured to the axle might be engaged by a pawl on the cart. Instead of being made of flat form as shown, the horse might be made of natural form and the legs disposed to keep it upright, the hind feet being rounded and provided with friction material. A realistic animal such as a dog may be constructed of two pivoted parts covered with a fabric or skin and stuffed ; and metal in wire, strip or pressed sheet form may be employed for the frame instead of wood.
