Filed: 1945-06-07
Abstract: 620,477. Amusement apparatus. AMAC, R. W. June 7, 1945, No. 14326. [Class 132 (ii)] [Also in Group XVIII]  An amusement machine comprises a plurality of inclined tracks 16 visible through a window 2 and having apertures 20 through which a coin or disc projected up the tracks by strikers 47 on a bar 53 operated by a handle 5 may run into the next lower track and in the case of the lowest track into a delivery chute 9. Each track comprises a base 14, a shallow outer rim 26, a back plate 18 and a top lip formed by the bottom of the back. plate of the next higher track. Channels 37 are formed behind the tracks 16 by the back plate 18 and an extension of the back plate of the next lower track. The apertures 20 feed into these channels and apertures 36 feed from these channels into the next lower tracks. A coin or disc fed into a slot 6 runs down a shoot 50 into a short channel 34 whence it drops into the topmost track coming to rest against a finger 52. The handle 5 is operated causing a pin 47 to project the coin &c., up the track to the opening 20 and, if the blow is of suitable strength, the coin passes therethrough into the channel 37 whence it is fed to the second track to be struck by another pin 47 and thus delivered ultimately to the shoot 9. If the coin is struck too hard, it runs over the end of the track and falls on to a deflector plate 58 and then to the bottom of the machine. The striking lever 53 is influenced by a spring 55 and the track assembly is mounted on battens 48 on a plate 49 hinged to the machine frame. The tracks may be adjusted in position. The coin mechanism may reject coins of unsuitable size or may be arranged so that insertion of a coin frees playing discs. A counter may be provided to record the number of operations of the strikers 47.

Filed: 1920-05-27
Abstract: 159,786. Igranic Electric Co., Ltd., (Cutler-Hammer Manufacturing Co.). May 27, 1920. Master control systems; systems for continuous current motors only.-Progressive accelerations of the motors is effected by successively acting lockout switches, each of which has a lock-out winding operative, while the motor current is fluctuating and inoperative when the current attains a steady value. In the arrangement shown in Fig. 1, a direct-current shunt-wound motor A is accelerated by three contactors 2, 3, 4 adapted to shortcircuit resistances R<2>, R<3>, R<4>. The contactors are closed by corresponding shunt windings 6, 7, 8 and held open by corresponding lock-out windings 10, 11, 12 respectively connected to the secondaries of three series transformers 15, 16, 17. The primaries of the transformers are so connected that only one at a time is in circuit, namely the one which is associated with the contactor next in order to be closed. The induced current that traverses the lock-out winding while the motor current is fluctuating retards the closure of the contactor. The degree of retardation can 'be varied by adjustment of windings and air-gaps. In a modification a single transformer, the secondary of which is connected to the lock-out coil in series,. replaces the three transformers shown in Fig. 1.

Title: Improvements in and relating to the treatment of liquors with solid adsorbents
IPC: B01D15/02
Filed: 1943-09-06
Abstract: 578,520. Purifying water and other liquids. TATE & LYLE, Ltd., and SIMMONS, C. E. G. Sept. 6 1943, No. 14555. [Class 46] [Also in Group VI] . For the treatment of liquors with solid adsorbents such as the treatment of sugar solution with bone char or with anion or cationremoval synthetic resins, the liquor is caused to flow in counter current to the adsorbent and to recover retained portions of the liquor the spent adsorbent is treated with washing liquid, also in counter current, which passes to and mixes with the liquor to be treated. Thus adsorbent fed by a pipe 11 passes downwardly in a limb 3 of a U-tube 1 in which limb is rising a sugar solution supplied to the base of the U-tube by a pipe 6. An impeller 12 feeds the adsorbent forward to rise in the other limb 7 of the U-tube where it is washed free of remaining sugar solution by water supplied from a pipe 8, the washings passing downwardly to join the main stream of sugar solution; the spent and washed adsorbent is drawn off by a pipe 13 for regeneration while the clarified sugar solution passes through a flaring enlargement 2 to a collector 4 with outlet 5. The regeneration and the rinsing of the adsorbent free from excess regenerant may be effected in a similar apparatus. Sulphonated coal or metaphenylene diamine resins may be used as the adsorbent resin. The Provisional Specification describes a form of U-tube comprising an inner tapering 'tubular member located within an outer chamber so that the concentric passageways form, in effect, the limbs of the U.

Inventor: DYER BERNARD STEPHEN
IPC: C08F2/22
Filed: 1950-06-15
Abstract: Vinyl chloride polymer dispersions are made by polymerizing vinyl chloride alone or admixed with another copolymerizable monomer, in aqueous media, in the presence of a dissolved polymerization catalyst, and an emulsifying agent which is introduced only after the polymerization has commenced but before any coagulation occurs, e.g. after a decrease in the vapour pressure of the system.  The ingredients of the polymerizable mixture may be added stepwise or continuously.  The polymer may be separated from the dispersion by coagulation or spray-drying. Specified emulsifying agents are sodium lauryl sulphate, sodium oleyl sulphate, sodium cetyl sulphate, the sodium salt of sulphonated castor oil, the sodium and ammonium salts of sulphonated or sulphated methyl oleate, sodium oleate, sodium palmitate, sodium stearate, ammonium palmitate, ammonium stearate and ammonium oleate.  The copolymerizable monomer may be vinyl acetate, vinyl propionate, vinyl butyrate, vinylidene chloride, acrylonitrile, ethyl acrylate, methyl methacrylate, methyl alpha-chloroacrylate, maleic acid, fumaric acid, diethyl maleate, and diethyl fumarate. Catalysts mentioned are hydrogen peroxide and the alkali metal and ammonium persulphates.  The catalysts may be used in conjunction with copper salts or with oxygen, as described in Specifications 589,264 and 598,777.  The dispersions may be used for treating textiles, paper, felt and yarns, and may contain pigments, fillers and heat-stabilizers.  The polymers may be used for the production of pastes in admixture with plasticizers, as described in Specification 589,715. Plasticizers mentioned are tricresyl phosphate, dibutyl sebacate, dibutyl phthalate, branched chain octyl and nonyl phthalates and linear polyesters such as those described in Specification 624,393.

Abstract: 1305507 Piston-cylinder dampers FICHTEL & SACHS AG 14 May 1971 [14 May 1970] 14979/71 Heading F2S [Also in Division B3] In a damper having a piston 6 with throughflow apertures 5, a partition 3 having a circumferentially closed rounded-in rim 7 is secured across the cylinder by axial deformation of the rim 7. The damper is partly filled with liquid and the partition 3 is located below the liquid level. The partition is valved such that there is a greater restriction to flow from the working chamber than into it. The space above the liquid compensates for the piston-rod volume. Alternatively (Fig. 2, not shown) the damper has pressurized gas in direct contact with the liquid. The partition is located in the liquid chamber and acts as a baffle to deflect the jets of liquid discharged from the piston apertures and prevent them disturbing the liquid-gas interface. The partition has a central opening. In both cases the partition is initially smaller than the cylinder diameter. The rim is axially deformed by press tools 17, 18, to cause an enlargement in diameter of the partition and secure it across the cylinder.

Title: Improvements in and relating to the production of regenerated cellulose filaments
Inventor: SMITH JOHN OLIVER
IPC: D01F2/06
Filed: 1955-05-25
Abstract: Regenerated cellulose filaments capable of developing a crimp upon subsequent relaxation in an aqueous liquid are produced by extruding viscose into an aqueous acid coagulating and regenerating bath containing sulphuric acid and at least 16% of sodium and zinc sulphates, and conducting the filaments through the bath for a length of time approximately equal to that throughout which the liquid absorbed by the filaments remains alkaline or neutral, after which excess liquid is stripped from the filaments emerging from the bath and the filaments then pass through an aqueous acid regenerating bath in which or after which they are highly stretched.  The neutral point is determined by carrying out a preliminary experiment in which bromcresol purple indicator is added to the viscose, the point at which the filaments change in colour from purple to yellow is observed, and the path length corresponding to this neutral point is measured. No indicator is used in the commercial production of filaments according to the invention.  The first bath preferably contains at least 20% of sodium sulphate while the regenerating bath preferably contains less than 12% of acid and less than 16% of total salts.  The bath in which the filaments are subsequently relaxed to impart to them a permanent crimp may be water or aqueous dilute acid or alkali.  The degree of stretching is preferably at least 35%.  The filaments may be cut into staple before or after the relaxing step. In an example, in which the path length corresponding to the neutral point is determined in a preliminary experiment as described above, and in which this path length is not exceeded, viscose is spun into an aqueous coagulating and regenerating bath at a temperature of 50 DEG  C. containing 9.5% of sulphuric acid, 24% of sodium sulphate and 0.8% of zinc sulphate.  The filaments are then conducted from the bath over a guide to strip off excess liquid and through an aqueous regenerating bath containing 5% of sulphuric acid, 6% of sodium sulphate and a very small percentage of zinc sulphate.  The filaments are stretched 50% after removal from the regenerating bath and allowed to relax in a water bath.
