Title: Improvements in railway vehicle brake riggings
Inventor: PERSSON GERT ARTUR
IPC: F16D65/28
Filed: 1967-04-18
Abstract: 1,136,670. Brake rigging. SVENSKA A.B. BROMSREGULATOR. 18 April, 1967, No. 17630/67. Heading F2E. A railway vehicle brake rigging comprises a first lever 5, Fig. 1, pivotally connected to a piston/cylinder 3 secured to a housing 1, a two-part axiallydisplaceable push transmitter having its first part engaged axially by the first lever and its second part engaged by a second lever 17 with the relative axial positions of the parts determined by adjustable means which are moved after a predetermined axial travel of the transmitter. With a low braking force and normal brake rigging slack the braking force is transmitted from the piston-rod 4 through first lever 5, the surfaces 7, 9, sleeve 11, pivot 19, third lever 17, sleeve 37, spring 35, sleeve 36, second lever 15 and pivot 13 to brake shoe 14 and brake block 33. Increasing braking force causes further compression of spring 35 so that clutch surfaces 24, 25 are separated and clutch surfaces 21, 22 engage allowing the braking force to be additionally transmitted through clutch surfaces 21, 22, nut 20, spindle 12 and pivot 13 to brake shoe 14. When the slack is excessive a ball bearing 27 engages a spring-loaded ring 29 before the clutch surfaces 24, 25 separate to cause the nut 20, which has a non-self-locking thread, to be moved to the right along spindle 12, thus causing the latter to be extended to take up slack. The adjuster functions similarly to increase the slack when necessary. In another embodiment a pair of brake riggings are mounted one on each side of a bolster 40, Fig. 4, each engaging a brake beam 41. The arrangement differs from Fig. 1 by the inclination of each first lever 5 to permit the mounting of both brake cylinders.

Title: Gaming machine
IPC: G07F17/34
Filed: 1974-06-27
Abstract: 1471866 Gaming machines A SHAW 27 June 1974 [12 April 1973] 17750/73 Heading G4V [Also in Division H2] A gaming machine has a rotating chance reel mechanism and a drive means, incorporating a stepping motor 1 operable to move the rotatable chance reel 4 through a series of incrementally spaced positions and automatically to hold the reel securely in any one of said positions when the drive is rendered inoperative. Play of the machine is instigated by pressing switch 22. Timer 24 operates pulse generator 5, either or both of which may have a random operation. Pulses are fed to phasing unit 6 which drives the stepping motor and hence reel 4 via gear-box 2. Frequency divider 10 divides the pulses by the reduction factor of gear-box 4. The output pulses are counted; up to 10 by a first stage 13 and in 10's by second stage 14. A semi-conductor switch device 19 is operated each revolution of the reel by shield 18 interrupting the field from magnet 17. The device zero's the counters and frequency divider 10. To ensure that the reel can only be stopped so that a symbol is showing at a viewing window there is a feed back circuit which is closed by switch 27 when the timer stops. Thus if the factor of division is 10 and less than 10 pulses have been generated then the pulse generator is kept operative until the 10 pulses have been reached. Output lines 16 are used to trigger a payout arrangement if appropriate. There may be three reels each with a separate stepping motor. The output lines 16 would then be connected to a comparator circuit for payout operation. The reel rotates at least one revolution at each operation. Switches 27, 28 may be of the mechanical, electromechanical or electronic gate type and are operated by timer 24. Switch 28 opens before switch 27 closes to prevent zeroing of divider 10 as a player may be deprived of a win. There is a reverse switch 31. A push-button switch 21 allows the reels to be moved independently and incrementally through a predetermined number of positions in either direction. This extra movement could be held over for several games. Further, one or more of the reels may be arranged to perform a rocking motion by moving alternatively in the forward and reverse directions by a predetermined amount, e.g. by six reel symbols, upon operation of a switch (not shown); the rocking motion occurring for a random time. If an aperture for viewing shows 3 lines of symbols a winning combination could be by a diagonal, horizontal and/or vertical line of symbols.

Title: Improvements in or relating to the manufacture of carbonaceous briquettes or agglomerates
Inventor: GREGORY DOUGLAS HAIG
IPC: C10L5/04
Filed: 1958-06-04
Abstract: Smoky coal is heated in finely divided form and converted into agglomerates either alone or in combination with smoky carbonaceous materials, e.g. semi-cokes or pitch.  The term "smoky carbonaceous material" is intended to exclude lean or semi bituminous coals which are naturally smokeless.  Subsequently the agglomerates are cooled at a controlled rate in an atmosphere containing oxygen, the smoke-producing constituents in the agglomerates being changed to such an extent that the agglomerates do not give off dark smoke when burned.  The finely divided coal may be heated in a fluidized bed with the aid of inert gases or gases containing oxygen.  The upper limit of the temperature to which the finely divided coal is heated is preferably such that there is no appreciable decomposition and the initial weight of the coal is substantially retained, the lower limit preferably being such that when the coal is briquetted the smoky agglomerates may be treated in the subsequent controlled stage without further heating.  Specified temperatures at which the finely divided coal may be heated are 250 DEG -500 DEG C. The operation of forming the smoky agglomerates is preferably effected without cooling the hot finely divided coal except by the cooling imposed by the addition of a binder in the cold state when a binder is used.  The agglomerates may be cooled in a stream of gas containing controlled amounts of oxygen.  The initial rate of cooling of the agglomerates is preferably less than 30 DEG C./minute. The agglomerates may be finally quenched with water by immersion or spraying.  Specification 897,755 is referred to.

Abstract: 246,532. Anode Rubber Co., Ltd., (Klein, P., and Szegvßri, A.). July 28, 1924. Addition to 223,189. Moulding indiarubber.-A modification of the process of depositing rubber from emulsions, such as latex, by electcrophoresis described in the parent Specification consists in using substances which prevent the emission of gas at the anode, with the result that homogeneous deposit of rubber can be obtained on the anode itself. The substances may be such as to absorb the gas produced at the anode, and may in this case be present in the latex, in the anode itself, or in the backing on which the rubber is deposited. Alternatively, substances may be added to the electrolyte, which are decomposed instead of the water and which yields at the anode solid or liquid products or gases such as chlorine which are readily absorbed. For example, if a carbon anode is used and a soluble thiosulphate is added to the latex, an intimate mixture of rubber and finely divided sulphur is deposited. A second modification of the parent process consists in using moulds of which portions consists of different substances, so that articles of varying thickness may be produced. For example, in the case of a mould composed partly of gypsum and partly of unglazed earthenware the deposit will be thicker on the former substance. A third modification of the invention consists in producing fabric-lined hollow articles by stretching a hollow fabric article, preferably knitted, over a mould of corresponding shape and electrophoretically depositing rubber thereon.

Abstract: 342,990. Substation circuits. TELEFONAKTIEBOLAGET L. M. ERICSSON, 33, Kungsgatan, Stockholm. June 12, 1930, No. 18105. Convention date, June 13, 1929. [Class 40 (iv).] In a system employing loud-speakers and amplifiers coupled to the line by differential transformers, the loud-speaker, as well as the line, is balanced to prevent back-coupling disturbances. The balance may be obtained by providing two loud-speakers which act both as receivers and transmitters. The amplifiers may be units separate from the transmitter and receiver. Two stations A and B may be connected over the lines L, which may pass through an exchange. At station A the received currents pass from the line to the secondary of transformer IT, through amplifier IF to loudspeaker A, the balance AB preventing the currents passing to the output circuit US. Outgoing currents pass to the secondary of UT via amplifier UF to the line, the balancing network ALB preventing disturbances in the incoming circuit IS. Similar apparatus may be provided at the station B. The balance AB may be a loud-speaker similar to A. The two loud-speakers may be mounted together and act together as both receiver and transmitter, the connections being such that the effect of the two instruments when used as transmitters is additive in UT. If the amplifying unit AF is mounted remote from the subscriber's instrument only three wires are needed to connect the set with the amplifier, whilst two only need be fitted if the balancing network AB is not a second loud-speaker. Echo blocking devices or backcoupling blocking devices may be added if required. The amplifiers UF may be omitted, the whole cf the amplification then taking place in the amplifiers IF. The Specification as open to inspection under Sect. 91 (3) (a) states that the balancing network AB may comprise the subscriber's microphone. This subject-matter does not appear in the Specification as accepted.
