Title: Bowling alleys
IPC: A63B69/00
Filed: 1962-08-01
Abstract: 1,011,524. Bowling alleys. AMERICAN MACHINE & FOUNDRY CO. Aug 1, 1962 [Aug 3, 1961], No. 29580/62. Heading A6D A bowling alley is provided, intermediate its approach zone 14 and pin deck 18, with an array of lamps either embedded in the floor of the alley as at 28, or mounted on a frame above the alley, the lamps being adapted to automatically furnish on the floor of the alley an array of illuminated spots corresponding to the array of pins left standing on the pin deck at any point of the game, in order to assist the aim of the player. Means are also provided to enable the player to control the illumination of the lamps for practice purposes. Each lamp 30 of the array 28 is wired in circuit with a relay 66 and micro-switch 74, the latter being automatically closed to energize the relays and illuminate the lamps if and when the pinsetting table grips the corresponding pin on the deck 18, as happens during the process of re-setting standing pins between throws by the player. A time switch 82 connected across each of the microswitches 74 controls the time interval during which the lamps remain illuminated. The apparatus also comprises an array of switches 72 for selective operation by the player, the switches.bypassing the relays and micro-switches. An indicator panel 26 may be provided, the lamps 76 thereof being adapted to operate simultaneously with the corresponding lamps 30 of the array 28.

Title: Sootblower
IPC: F28G3/16
Filed: 1960-08-29
Abstract: 894,548. Soot blowers. THOMPSON (AUSTRALIA) PROPRIETARY Ltd., JOHN. Aug. 29, 1960 [Sept. 8, 1959], No. 29732/60. Class 99(2). A soot-blower com prises a bearing tube 26 extending through a fire box wall 29 and into the fire-box and forming a part of a stator assembly adapted for mounting on the wall, an assembly which is axially movably inside the stator assembly, and a nozzle tube 31 housed inside the tube 26 and forming part of the movable assembly and which is provided with a cleaning fluid outlet. There are actuating devices incorporated in the assemblies which in response to the application of fluid pressure thereto axially advance the nozzle tube so that the outlet end thereof projects into the fire-box beyond the adjacent end of the tube 26, and means for retracting the nozzle tube from the axially advanced position in response to cleaning fluid pressure. As shown the nozzle tube 31 has a keyway 33 slidable longitudinally of a key 34 fixed in a bearing sleeve 35 mounted in antifriction bearings 36 in a easing 27, and includes an impeller head 37 formed with helical vanes 38 and rotatable within the skirt 39 of a non- rotatable piston 40 having fluid ducts 50 communicating with holes 49 in the head 37 and ducts 52, 53 leading to the clearance space 54 between the nozzle tube and bearing tube 26. Cleaning fluid is admitted via a main valve 56 to the chamber 28 to project the nozzle tube against the action of a buffer spring 45, and via a valve 61 to the ducts 51 to cause the tube to rotate. On completion of a soot-blowing operation, the valves 56, 61 are closed and the twoway valve 57 operated to admit cleaning fluid to the ducts 52 via the pipe 60 to thereby retract the nozzle tube. The nozzle tube oultets 16 may be formed tangentially of the tube so that the tube is rotated by the reaction of the cleaning fluid jets. The nozzle tube may be non-rotatable in which case the fluid spaces defined by the element 38 are straight instead of helical. The tube 26 passes through at least one of the water tubes 30 of the boiler and is thereby kept relatively cool; alternatively, the tube is coated with refractory material and projects between adjacent water tubes. The plug 15 of the nozzle tube may be omitted and the outlet end of the tube be fashioned to form a restricted nozzle outlet.

The latch plate is urged into its engaged position by a spring biased T-shaped lever 69 pivoted to the cradle at 68 and having an upstanding arm 79 with a hook portion 82. When the cradle is retained in its horizontal, working, position by the engagement of the hook portion 82 with a stop plate 31 secured to the pivoted cabinet flap 24 a cam surface on the stop plate deflects the lever to withdraw the latch plate and free the machine from the cradle.

Ammonia, catalytic production of from nitrogen and hydrogen; catalytic apparatus; catalytic agents, treatment of.-To facilitate the renewal of the catalytic material employed for the synthesis of ammonia under hyper-pressure conditions, the inner tube containing the catalyst is rigidly secured to the removable head of the permanently-fixed outer pressure tube. The inner tube T containing the catalytic material G is mounted on the exit tube L, which passes centrally through the screwed head D of the procure tube H. By unscrewing the head D, the inner tube T is withdrawn and can be refilled after removal of the gauze plug R; or the whole combination T, D may be immediately replaced by another in which the catalytic material has already been " formed," preferably by means of the pressure hydrogen issuing from the last catalyzing tube of the plant. To ensure a firm screw connection between the head D and the pressure tube H, the head D is kept cool by passing the cold entering gases directly through it by orifice A and aimular conduit O at the same time keeping the hot exit gases out of contact therewith by employing an asbestos lining M for the exit tube. The screw-thread on the head D may be continuous but is preferably interrupted, like that of a gun breech-block. The connection N between the catalyzing tube and the ammonia liquifier is immersed in cold water. The pressure tube H is made of a metal adapted to resist the action of the gases present, such as the alloys ATC and BTG, the composition of which is described in Specifications 140,508 and 159,857, [both in Class 82 (i), Metals, Extracting &c.].

Other materials such as pitch, particularly animal pitch, gums, ester gums, waxes, rosin, cumarone, copal, may also be added in like manner. Accelerated drying properties may be obtained by the like incorporation of driers such as litharge, manganese dioxide and hydrochloric acid, manganese resinate, copper oleate or carbonate, copper ammonium hydroxide or other copper compounds. Varnishes are obtained by the similar addition of a solvent such as gasoline, kerosine, or the material sold under the Registered Trade Mark " Varnoline." The heating may if desired be effected under pressure or with the simultaneous injection of air into the liquid. Specifications 259,959, 262,134, 272,509. 272,510 and 275,574 are referred to The Specification as open to inspection under Sect. 91 (3) (a) describes also heating the liquid (1) alone, in general (2) in the presence of metals or metal compounds such as copper, lead, manganese, lead oxide, copper ammonium carbonate, copper carbonate or oleate &c., or treating the liquid with aldehydes such as formaldehyde or furfurol.

Title: Improvements in or relating to semi-conductor devices
IPC: H01L29/06
Filed: 1959-09-04
Abstract: 906,036. Semi-conductor devices. SIEMENS & HALSKE A.G. Sept. 4, 1959 [Sept. 5, 1958], No. 30278/59. Class 37. A semi-conductor device having a forward biased PN junction between an emitter and base zone is so designed that the minority carrier concentration is effectively constant in a region extending into the emitter zone from the junction. A surface portion of the emitter zone is treated to reduce the recombination velocity and provided with one or more ohmic contacts covering only a small portion of the emitter zone surface. In one embodiment, in which the emitter zone is much thinner than the minority carrier diffusion length, the effectively constant concentration is produced by treating the entire surface of the emitter zone and using a small area central ohmic contact 9 (Fig. 2), several such contacts, or an annular contact. Another way of obtaining constancy of the minority carrier concentration in the emitter and hence of increasing its efficiency is to form the zone in two parts as shown in Fig. 3. The P-type part 2, which has a lower net impurity concentration than base zone 3 or P+ emitter part 6, is less than a diffusion length thick. Contact 4a to the emitter zone may be made in any of the ways mentioned above. An additional ohmic contact or contacts may also be provided to part 2 of the emitter zone. In operation, contact 4a or the additional contact(s) may be left floating or both connected in circuit.

The magnesium chloride and alkali metal or ammonium chloride may have a molar ratio of 1 : 1 and be present either as a mixture, or as a double salt. The rock phosphate may be introduced into a bath of the molten chlorides or it may be admixed with the solid chlorides and the mixture heated to sintering or complete fusion.
