Title: Improvements in or relating to apparatus for playing a game
IPC: A63H18/14
Filed: 1936-07-02
Abstract: 462,513. Game apparatus. GUILLAUME, R. July 2, 1936, Nos. 18407 and 18408. Convention dates, July 31, 1935 and May 16, 1936. [Class 132 (ii)] In apparatus for simulating a race game, a fixed board, on which the course with starting, finishing &c. points are marked, is provided with a sinuous slot or slots along which objects such as model cycles, are moved by the rotation of a member or members beneath the fixed board, the connection between the models and the rotatable member(s) readily permitting the models to follow the sinuous course. In one embodiment, the movable objects, cyclists, motor cyclists, horses, boats, aeroplanes or cars 7 are carried on pins 5, Figs. 1, 2, slidably mounted in slots 6 in a rotatable plate 4, and, as the latter is rotated, the pins 5 move along a sinuous slot 10 in the fixed board 9. The plate 4 is rigid with a flywheel 3 and is driven through gearing 12, 13, 14 and a rack 16 by a spring 15 energized by pulling out the rack bar at 17, ratchet or freewheel mechanism being provided in the drive to disengage the flywheel during energization of the spring. Owing to the shape of the slot 10 the models 7 appear to approach and recede from each other, simulating a race, the winning model being that which comes to rest nearest a point P. The plate 4 may be replaced by suitable rotatable link mechanisms permitting the radial movements of the models as they move along the sinuous slot 10, and, in the case where the upper surface of the board 10 constitutes a relief map, the pins 5 are articulated so that the models may also move vertically, according to the altitude on the map. For example, each of the pins 5 may be mounted at the apex 29, Fig. 7, of a link triangle 26, the link 28 of which is slidable in a guide 32 rigid with the rod 33 rotated about the axis 2, Fig. 2. In another embodiment, Figs. 9, 11, a plurality of models 43 move round individual sinuous slots 39 in a board 9, the pieces of the board, such as 52 between the slots, being supported by bridges 53 or other similar elements. Each model 43 has a depending hook 40 engaging the slot 39 and is connected by a flexible cord 42 to a corresponding endless band 50a, 50b passing round pulleys 44a, 45a and 44b, 45b respectively, the spindle 46 being driven, for example by a mechanical motor 47 wound at 48. The device may comprise a larger number of slots 39 arranged substantially parallel, with one or more models for each slot, and the driving motor may be electrical or pneumatic. The apparatus may be coin-controlled.

Title: Apparatus for the determination and/or regulation of the fat content in milk
IPC: G01N9/10
Filed: 1936-07-03
Abstract: 460,006. Fluid-pressure servomotorcontrol systems. BERGEDORFER EISENWERK AKT.-GES. ASTRA-WERKE. July 3, 1936, No. 18486. Convention date, July 5, 1935. [Class 135] [Also in Group XX] The invention relates to apparatus for determining or regulating the fat content of milk from a centrifugal cream separator by a comparison between the specific gravities of the skim milk and the milk the fat content of which is to be standardized. Displacement bodies c, d are suspended from the ends of a graduated beam e pivoted at the centre f and are immersed respectively in the skim milk and in the milk to be standardized. The chambers a, b, containing the bodies c, d, have upper walls l closely conforming to the shape of the bodies to provide damping and having apertures m for the passage of the milk. In a modification the bodies, c, d may be replaced by containers filled with skim milk and milk to be tested respectively. A weight movable over the left hand half of the beam and a weight one tenth of the first weight and movable over the right-hand half of the beam are adjusted on the graduations in accordance with the desired percentage fat content, the balance then being in equilibrium only when the milk in the chamber b is correctly standardized. This is effected by a valve which allows a part of the skim milk to pass into the pipe delivering the creamy milk or vice versa according as to whether the standardized milk is to contain a higher or lower percentage of fat than the milk fed into the separator. The valve may be controlled manually or may be an automatically controlled diaphragm valve which is held closed by a spring and drawn open by reduced air pressure provided by a vacuum pump. A nozzle, the opening of which is controlled by an arm (not shown) on the beam e is connected to the pressure chamber of the valve so that the latter is controlled and the fat content of the milk consequently varied in accordance with the position of the beam e.

Title: Improvements in signal translating apparatus correction systems
IPC: H04N5/202
Filed: 1952-07-23
Abstract: 722,146. Copying telegraphy. RADIO CORPORATION OF AMERICA. July 23, 1952 [July 31, 1951], No. 18671/52. Class 40 (3). In apparatus for controlling an image reproducing cathode-ray tube so as to obtain a linear or predetermined shape of transfer characteristic, the beam current is switched on and off by a source of pulses of sufficiently high frequency to prevent resolution of the dot structure on the screen and the image signals are applied to control the duration of the pulses. By employing linear saw-tooth pulses which are clipped to obtain square waves at a level determined by the image signals a linear transfer characteristic is obtained. By employing a wave shape others than saw-tooth, other arbitrary transfer characteristics may be obtained. In the Figure sawtooth waves are generated across condenser 38 by valve circuit 10, 20 and applied to the grid of triode 40. The peak position level of the saw-tooth is set to the stabilized potential at the junction of resistors 70, 72 by the righthand diode 60. Triode 40 functions as a cathode follower to apply the saw-tooth wave to the triode 50 by virtue of the common cathode resistor 48. Image signals obtained from a source of signals 80, such as a flying spot scanner, are applied through amplifier 84 to the grid of triode 50. The signals control the level at which the valve cuts off under the action of the cathode saw-tooth wave and are applied in such sense as to increase the level of the sawtooth at which cut off takes place with increase of signal. By this means there is obtained from across anode load 56 a substantially rectangular wave, the width of which is controlled by the image signals. Potentiometer 86 permits the bias to be set such that no output of rectangular wave is obtained with zero image signal. The output from load 56 is applied to the grid of cathode-ray tube 90 and the upper level of the wave is set to the potential at the junction of resistors 75, 76 by the left-hand diode 60. The bias 96 for the cathode-ray tube is set so that the rectangular pulses switch the beam on and off. A photographic film or plate is placed in front of the screen of the tube to develop the image thereon.

Patent GB-956598-A (GB)
Title: Chlorine manufacture
Inventor: HUNTER EDWARD
Filed: 1961-05-25
Abstract: Chlorine is made by a four stage process, the first stage being the production of ammonium chloride from ammonia by known methods; the second stage being the reaction of the said ammonium chloride, a chloride of a metal in a lower valency state, and ammonia in an aqueous system with oxygen or air, whereby a chloride with the metal in a higher valency state is formed and is combined with ammonia in solution to give an ammine; the third stage involves the separation and drying of the ammine and heating it to drive off ammonia without decomposing the higher chloride, ammonia being returned to the first and second stages; and the fourth stage comprises heating the higher chloride to give chlorine, the lower chloride also formed being returned to the second stage. Metals whose chlorides may be used include copper, cobalt, and chromium. The second stage reaction is carried out at a temperature of 20 DEG  to 70 DEG  C., the initial concentrations of both ammonium chloride and metal chloride, e.g. cuprous chloride, ranging from 4 to 6 molar and that of ammonia from 12 to 18 molar.  Using copper as the metal, the cupric chloride ammine formed may be decomposed into its components either at a temperature of 200 DEG  to 250 DEG  C. under atmospheric pressure or at a temperature of 180 DEG  to 230 DEG  C. under less than atmospheric pressure.  Chlorine is then liberated from the cupric chloride by heating at a temperature above 450 DEG  C. Ammonium chloride for the first stage may be obtained either by direct combination of ammonia and hydrogen chloride or as a product of the ammonia-soda process.  It may be introduced to the second stage in solid form or as an aqueous solution, which may contain dissolved electrolytes e.g. sodium chloride provided that they do not interfere with the formation and separation of the ammine.  Aeration with air or oxygen is effected at a gradually diminishing rate in order to prevent loss of ammonia. Carrier gas e.g. nitrogen may be used to recover ammonia liberated on heating ammine by rapidly passing the carrier gas through a fixed bed of solid ammine and silica wool at a preferred temperature of between 220 DEG  and 230 DEG  C. at atmospheric pressure.

Abstract: 1364921 Estrogen conjugates S J GROSS 4 June 1971 [11 June 1970 16 Nov 1970] 18944/71 Heading C2U [Also in Divisions A5 C3 and C4] The invention comprises an antigen having a purity of at least 98% and being of formula wherein "carrier" is an immunogenic carrier (e.g. a protein, polysaccharide, polypeptide or glycoprotein); Ar is an optionally substituted arylene or divalent aromatic heterocyclic radical to which the carrier is linked through a connective group (e.g. -NH-CO-); and "estrogen" is a steroid grouping attached to the azo group at position 2 or 4 and having a "nucleus" of formula wherein R is H or C 1-4  alkyl; R<SP>1</SP> is H, alkyl or acyl; R<SP>2</SP> is hydroxy or acyloxy; R<SP>3</SP> is H; or R<SP>2</SP> and R<SP>3</SP> together are oxo; R<SP>4</SP> is H, hydroxy or acyloxy; R<SP>5</SP> is H; or R<SP>4</SP> and R<SP>5</SP> together are oxo; with the proviso that R<SP>2</SP> and R<SP>4</SP> are not both hydroxy. Specified protein carriers are bovine serum albumin, keyhole limpet hemocyanin and human gamma globulin. The antigen generally comprises a plurality (e.g. 5-29) of Ar-N= N-estrogen moities coupled to a single carrier molecule. The above antigens are prepared from the parent estrogens (e.g. estrone, estradiol, 17α- estradiol) by reaction with diazotized HO 2 CAr-NH 2  to give which is chromatographed to separate the 2- and 4-azo isomers from each other and from the 1-azo by-product. The 2- or 4-isomer is then coupled to the carrier in known manner, e.g. by reaction with a carbodiimide or thionyl halide to give (wherein R<SP>6</SP> and R<SP>7</SP> are each alkyl, cycloalkyl, aryl, alkenyl, cycloalkenyl or heterocyclic) which is then reacted with the carrier to give the desired antigen which is purified, e.g. by dialysis. Reduction of the above HO 2 C-Ar-N= N-estrogen intermediates, e.g. with NaBH 4 , yields a mixture of fluorescent compounds of formula which may be separated by chromatography and extraction techniques. The above antigens may be made up with diluents into injection solutions.
