Title: Improvements in water softening apparatus
IPC: C02F1/42
Filed: 1927-07-19
Abstract: 298,997. Baron, H., (Neumann, W.). July 19, 1927. Purifying liquids.-In apparatus for softening water by base exchange, in which the treating- material is circulated through a regenerating chamber during the softening operation, independent driving means are provided for operating valves which control the circulation. The water, under treatment, supplied through pipes 12, 13 and a distributing device 15, passes upward through zeolite 39 and is discharged through a pipe 17. A rinsing-chamber 5 in the upper part of the softening-chamber communicates with the latter through a plate valve 23 and with the atmosphere through holes 32, Fig. 3, in a sleeve 33, a valve 43, and a pipe 24. The head 42 of the rod 48 of the valves 23 is engaged, above and below, by springs 50, 51 in a chamber 46 fixed to the end of a rod 10. The rod 10 passes through a sleeve 45 on the valve 43, which is engaged by a spring 49. The rod 10 is moved vertically by a crank on a shaft 8, which is driven by a motor 6 and which also operates a device 21 measuring and delivering brine from a tank 3 to a pipe 19. When the valve 43 is open, the device 21 is operating, and under the pressure in the softening-chamber, zeolite is forced through a pipe 18 and mixes with brine from the pipe 19, regeneration being completed in a vessel 2, from which the material passes through a pipe 22 into the rinsing chamber 5. Rinsing-water rises through apertures 47 in the plate 23, and, with the usual brine, escapes through the valve 43 and pipe 24 to a launder 26. The circulation is regulated by valve 27 on the pipe 24. Some softened water is admitted to the vessel 2 from a pipe 29, which also supplies water to the tank 3 for the brine solution. When the operating gear closes the valve 43 and opens the valve 23, zeolite passes from the rinsing-chamber into the softening- chamber. A shield 16 is provided below the valve 23 to prevent contamination of the softened water by brine. Modified apparatus is described having a larger regenerating chamber with an upper compartment with similar fittings to the chamber 5, the zeolite from the bottom of the softening chamber being passed into the main compartment of the regenerating chamber through this upper compartment.

Title: Improvements in or relating to barometric instruments
IPC: G01L7/00
Filed: 1958-06-17
Abstract: 884,555. Barometers; indicating-apparatus. WALZ, K. B., and HUGER, W. June 17, 1958 [June 18, 1957], No. 19295/58. Classes 106 (2) and 106 (4). In a barometer the measuring element 7 displaceable in response to change of pressure acting on a pressure-sensitive device such as aneroids 11, 12, 13, engages in a re-entrant bulge 4 in a generally circular closed spring loop 3 whose unstressed diameter is greater than that of a rigid ring 2 in which the loop 3 is compressed. The spring loop 3 is held by a bracket 6 with a threaded shaft 7 screwed on to a pin 9 secured to the aneroids 11, 12, 13. Alteration of atmospheric pressure causes compression or extension of the aneroids so that the shaft 7 is shifted. A pin 18 is carried on a slide member 17 on the shaft 7. Movement of the pin 18 due to movement of the shaft 7 is transmitted at an increased ratio to a pointer 31 through a lever 19, a pin 24, a lever 25, a bar 30, Fig. 2 (not shown), of a shaft 26 and at a still greater transmission ratio to a pointer 35 through the lever 19, the pin 24, the lever 25, a rack 32, a pin 33, Fig. 3 (not shown), and a bearing plate 34. The pointer 35 is rotatable for several revolutions over a dial 36 and the pointer 31 indicates, on a separate transparent dial 37 superimposed on the dial 36, the particular range of the dial 36 on which the indication of the pointer 35 is to be read. An adjustable setting pointer 48 is also provided.

Title: Radio direction finder
IPC: G01S1/02
Filed: 1935-07-05
Abstract: 449,982. Directive wireless signalling. SANDFORT, M., 2240, Grove Street, Berkeley, California, U.S.A. July 5, 1935, No. 19297. [Class 40 (v)] The directional effect of a frame aerial when receiving maximum signal - strength is made more clear-cut by applying the pickup voltage from a second aerial to regulate the amplification of the incoming signals quantitatively and over a wide range of deflection. As shown in Fig. 1, a frame aerial 1 feeds a screen-grid amplifier 5 which is coupled to a rectifier 20 biassed at 21 to cut-off, so that the signals increase the current through a visual indicator 25. The same signals picked up on a second frame 30, at right-angles to the first, serve to increase the plate current from a rectifier 46, which, since it passes through a resistance 18 in the screen-grid circuit of the amplifier 5, varies the bias on that grid, and therefore the effective amplification of the valve. When the aerial 1 is in the maximum position of pick-up, the aerial 30 is receiving no signal voltage, and the amplifier 5 gives a clear-cut response at maximum gain on the indicator 25, as shown by the curve 102 in Fig. 4. In Fig. 3 the two aerials 104, 105 are coupled to a radiogoniometer 110, 111, the latter being grounded through a resistance 109. Both aerials then combine to produce a " vertical " component which removes the 180‹ ambiguity, in the " sense " of the direction.

Title: Method of degreasing sheep and goat skins or similar skins
IPC: C14C1/08
Filed: 1948-07-19
Abstract: 645,040. Degreasing skins. FRIESTEDT, S. July 19, 1948, No. 19301. [Class 76] Pickled sheep and goat skins, after liming and puering, are degreased by placing them in an ammonia bath of such strength that, after the pickle acid has been neutralized, the bath remains alkaline and the excess ammonia reacts with that part of the fat which has been saponified during the liming to form soluble ammonia soaps. Preferably the skins remain in this soap solution for a sufficient time to emulsify any unsaponified fat. Skins are pickled by drumming for 1 hour in hydrochloric or sulphuric acid containing common salt and drained. The pickled skins are drummed with a solution of 3 per cent concentrated ammonia in 400 per cent water (based on pickled skin weight) for ¢-3 hours at 92-100‹ F. and then dried. If necessary, the dried skins are treated with ammonia again or drummed with varnoline at 125-135‹ F. for 20-30 minutes with subsequent removing of varnoline by putting out or centrifuging and washing with running water. The skins may be repickled after treatment. Other fat-dissolving agents such as trichlorethylene or kerosene may be used in place of varnoline, and emulsifying agents may be added.

Title: Improvements in and relating to couplings and coupling systems for railway vehicles
IPC: B61G5/04
Filed: 1919-08-07
Abstract: 153,656. Spencer, A., and Craven, A. Aug. 7, 1919. Couplings, automatic.-In an automatic coupling of the Norwegian hook type, the hook a, Fig. 2, is mounted on a pin b movable in slots c so that the coupling can be tightened by means of a right and left handed screw s and a link u pivoted on a fixed pin w, the coupling-head d being connected to draw-gear comprising a T- headed draw-bar e so that the head is flexible during traction but is prevented from moving angularly during buffing. The draw-bar e is combined with buffing and draw springs m, h' respectively, located on opposite sides of a fixed plate k, so that normally the rear portion f of the coupling-head is held by the spring h' in contact with a non-rotatable guide-block h, Fig. 3. and the coupling-head is fixed, but, during traction, the coupling-head is pulled forward from the guide-block and can flex freely. Transition to a coupling system using couplings as above described from a system using the rotary disk-hook couplings may be made in the following stages. The couplings of each existing vehicle are modified as described in Specification 152,458 and as shown in Fig. 5, so as to have at one end a rotary disk-hook 3 and at the other end a jointed link 12 capable of coupling either with a rotary disk-hook or with a Norwegian hook as shown in Fig. 2. Each new vehicle is provided with couplings by utilizing the couplings of an existing vehicle and two spare T- headed draw-bars, giving in the result the existing vehicle with a coupling having a double link 12 at one end and a coupling with a Norwegian hook as in Fig. 2, fitted on a spare draw-bar at the other end, and a new vehicle having at one end one of the coupling-heads of the existing vehicle fitted on with jointed link 12 and attached by the other spare draw-bar and at the other end a Norwegian coupling-hook as shown in Fig. 2. When all the rotary disk-hooks have been abolished, the jointed links 12 can be gradually replaced by pins q as shown in Fig. 2. During these stages the couplings of the locomotives have to be capable of coupling either with the hook or the link type of coupling. The coupling of a locomotive is therefore first modified as in Fig. 9 by being fitted with a jointed link 12 and a removable rotary disk-hook 3; then, at the stage when the rotary disk hooks of the locomotives are replaced by Norwegian hooks and the jointed links 12, by fixed pins.

Title: Fermentation Processes Utilizing Gaseous Hydrocarbons
IPC: C12N1/30
Filed: 1968-04-24
Abstract: 1,185,123. Organic compounds from hydrocarbons by fermentation; riboflavin. KYOWA HAKKO KOGYO CO. Ltd. 24 April, 1968 [15 May, 1967], No. 19486/68. Headings C2C and C2V. [Also in Division C6] A process for producing organic compounds (other than proteins) involves culturing a gaseous hydrocarbon assimilating micro-organism capable of producing the organic compounds, in an aqueous nutrient medium under aerobic conditions and in the presence of gaseous hydrocarbons as the main carbon source. Methane, ethane, propane, n-butane, iso-butane, propylene and butylene are the specified gaseous hydrocarbons. According to an example, the micro-organism Brevibacterium ketoglutamicum ATCC 15587 was cultivated in an aqueous medium containing a substantial supply of nitrogen (as ammonium nitrate and corn steep liquor) in the presence of n-butane gas and air, and on the third day of cultivation there was added to the culture medium cetyl trimethyl ammonium bromide. The product included L-glutamic acid, alanine, valine and lysine. When penicillin G instead was added at the 24th hour of cultivation, the product included L-glutamic acid, trehalose, glucose and riboflavin. Cultivation in a medium containing only a small supply of nitrogen gave α-ketoglutaric acid and citric acid. Adenosine-5<SP>1</SP>- phosphate, adenosine diphosphate and adenosine triphosphate can also be obtained by the process.

Title: Improvements in or relating to apparatus for playing table games
IPC: A63D13/00
Filed: 1940-08-02
Abstract: 536,571. Table game apparatus. MEYER, K. E., and FAUPEL, A. P., Aug. 2, 1940, No. 19661/39. [Class 132 (ii)] [Also in Group XVIII] In an apparatus for playing a game of the bagatelle type wherein the player may influence the movements of the ball by magnetic means, movable or fixed' magnetic means are provided and, when movable, the magnetic means are arranged to have a short range of movement only, and when fixed, are capable of energization through switches each of which is so arranged with respect to the others that, when one of these switches is operated, any one of them which has been previously operated will open automatically. As shown in Fig. 2 in connection with a coin-freed apparatus the balls resting in holes 5 in the table are liberated by pushing-in a coin slide connected to an apertured slide 4. The liberated balls run down an inclined board 8 and are raised to the spring- pressed projecting plunger by a grooved strip 9 actuated by the return movement of the coin slide. Near the top of the table slightly beyond each of the three uppermost holes 5 is an electromagnet 12. The electromagnets are connected through a spring-actuated time switch to three pairs of corresponding spring contacts 15, 16 adapted to be closed by the depression of three plungers 18. The circuits can, however, only be closed provided the time switch has previously been thrown into action by pressing- in a coin slide after insertion of a coin therein. Each of the plungers 18 is provided with two teeth. On depression of a plunger its upper tooth latches beneath a locking bar. If a further plunger is then depressed its lower tooth temporarily displaces the locking bar and liberates the latched plunger. A master switch accessible only by an authorised person may be provided to interchange the circuits between the plungers 18 and the magnets 12. In a modification, instead of using fixed electromagnets, permanent magnets movable by cables and plungers are used, the plungers being unlocked for use by a mechanical connection with a time-switch coinslide. Strips of iron are let into the table above the magnets so that by pulling the magnets from beneath the strips they no longer influence the balls. Non-magnetic shrouds prevent the balls lodging upon and sticking to the magnets. Instead of, or in addition to, the magnets described above one or more permanent magnets mounted on a pivoted arm may be employed. The magnet is situated over a plate of iron arranged slightly higher than the tops of the balls so that the magnet will influence the ball until the magnet is raised by depressing a handle.
