Title: Amusement apparatus
IPC: G07F17/32
Filed: 1937-02-04
Abstract: 489,862. Coin - freed amusement and delivery apparatus. DEHN, F. B. (Exhibit Supply Co.) Feb. 4, 1937, No. 3352. [Class 27] [Also in Group XV] An amusement device of the type in which upon insertion of a coin, articles of merchandise positioned on a platform may be selectively removed from the platform by a crane or derrick-like arrangement provided with an arm equipped with a grab, includes, as power actuated means for positively moving the boom arm of the crane through a predetermined cycle for gripping and releasing an - article of merchandise, a motor, a shaft driven thereby, levers under control of the shaft and flexible tension elements interposed between the levers and the grab and the boom arm to determine the position of the boom arm and of the grab in accordance with the movement of the shaft. A boom 25 carrying an arm 24 and rotatable by a cord 47 is secured near one side of a table 10 on which the merchandise is supported. The table is rotated by a motor 30. A grab 26, raised and lowered by cords 49, 51 is carried from the free end of the arm. The cords are actuated by a motor 40, cam shaft 42, and levers 46, 48, 50 in predetermined sequence to swing the boom arm 24 across the table, lower and raise the grab and release same over the delivery opening 14. At the end of a revolution the cam shaft opens a mercury switch in the mains and the apparatus is ready for replay. The rotary movement of the boom 25 may also be influenced either prior to, or after the insertion of a coin, by a hand wheel 60 and cord 65. When a coin slide 78 is pushed in a pin 100 thereon rocks a spring-returned arm 106 to close temporarily switch 73 in series with a relay. A switch 116 is also opened. The coin drops on to a lever 74 and tilts the mercury switch into closed position thereby setting the motor 40 and merchandise table into rotation. During the return of the coin slide the arm 106 returns under the restraint of a dashpot 110, the switches 73 and 116 are closed, and the relay is energized to stop the table-driving motor 30 and start the grab-actuating motor 30. A control switch may be manipulated by the operator to energize the grab-actuating motor 40, independently of the condition of the switch 73 and at the same time stop the rotation of the table in a favourable position. In a modification, the merchandise table is stationary and the boom projects through the central opening 14, the arm 24 being replaced by a gib pivoted to the boom. The rotation of the boom to set the grab over the desired article is effected by manual adjustment of a hand wheel, the swinging movements of the gib and the actuation of the grab being effected by cords and a cam shaft driven by the motor 40. Additional manual adjustment for swing- ing the gib towards and away from the table is also provided.

Abstract: 327,791. Guy, S. S. Feb. 1, 1929. Heating and cooling lubricant.-In a lubricating system for internal-combustion engines provided with both heating and cooling devices, the arrangement being such that for starting purposes the heating device is made active and the cooling device short-circuited, while for normal running the heating device is rendered inactive and the cooling device brought into operation, the cooling device comprises an oil radiator incorporated in the construction of the engine water radiator. Oil drawn from the bearings and sump by a pump d is forced by a pump d<1> to a tank c, whence it passes to the bearings through a coiled pipe e enclosed in a heating chamber f. The supply of heat to the chamber f, which is derived from the engine exhaust gases or circulating water, is controlled by a valve g. A valve h controls alternative paths for the oil from the pump d<1> to the tank c, one path c<1> leading direct to the tank while the other j leads through the oil radiator i. The two valves are interconnected in such a way that when the valve g is closed the oil is caused to pass through the radiator, and are operated either by hand or by a thermostat.

Abstract: 1,212,512. Gas turbine plant and combustion chambers. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. April 22, 1968 [Jan.23, 1967], No.3410/67. Headings F1G and F1L. [Also in Division F4] In a gas turbine plant having a compressor, combustion chamber and turbine, fuel and air are supplied to the combustion chamber in substantially stoichiometric proportions and water preheated in a compressor inter-cooler is also injected into the chamber to such extent that any corrosive products contained in the combustion gases are cooled below their fusion points. The plant, Fig.1 (not shown), is substantially the same as that described in Specification 1, 212, 511 and includes a main combustion chamber (1) and an optional reheat combustion chamber (17). The main combustion chamber has a vertically mounted outer casing 20 containing a lining 22 defining a combustion zone A and a quenching zone B. An injection assembly 21 supplies residual fuel oil to the combustion zone through an inlet 2 and air from the plant compressors through coaxial inlets 3a, 3b, the proportion of air only slightly exceeding the stoichiometric value. An igniter 23 effects ignition. Water preheated in compressor inter-coolers is injected into the combustion products in zone B through holes 24a in curved pipes 24 to cool the products below the solidification temperature of corrosive impurities (e.g. V 2 O 5 , NaSi) contained therein. In so doing the water evaporates into super-heated steam. Water also enters the combustion zone through tangential nozzles 28 from a space 27a surrounding the lining 22, this water swirling in a helical path along the inner surface of the lining 22 to pick up the solidified impurities and carry them into a region 40 at the bottom of the casing 20. From the region 40 the water and impurities can be drawn off through an outlet 41 or returned via outlets 42 and toroidal header 43 to the space 27a. The gas/steam mixture flows through the outlet 26 of the combustion chamber to the high-pressure turbine (5) of the plant and thence through the reheat chamber (17) to a lower pressure turbine (9). Further water may be injected into the reheat chamber. The pressure ratio of the plant is such that the inlet temperature of the turbine (5) is around 600‹ C. and the temperature of the working fluid does not fall below the dewpoint of sulphur compounds (e.g. sulphur trioxide) in passing through the turbine and its immediate exhaust system.

Abstract: 393,363. Starting Diesel engines. HUMBOLDT - DEUTZMOTOREN AKT.- GES., 149, Deutz Mulheimerstrasse, Deutz, Cologne, Germany. Feb. 6, 1932, No. 3588. Convention date, Feb. 17, 1931. Drawings to Specification. [Classes 7 (iii) and 7 (v).] In a method of starting Diesel locomotive engines having a direct drive on to the axles, combustion of fuel and compressed air is initiated by means of an ignition device in the cylinder, the compression and combustion pressures being considerably reduced compared with normal working and the injection and combustion period being considerably prolonged. Preferably the starting compression is not more than two-thirds of normal and the injection period is at least doubled. The ignition device may be an incandescent spiral of metal such as nichrotherm or a ceramic semiconductor such as carborundum or silit. The reduction of compression may be effected by the periodical opening of an air escape valve, by a throttle valve opened during the advance of the piston, or by increasing the compression space. The controls for the fuel inlet valve and the compressed-air inlet valve may be coupled to a hand-operated control and to the compression-reducing valve in such a manner that as the compressed air and fuel supplies are reduced to normal the compression is increased to the full normal value.

Abstract: 1450626 Integrated circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 29 Jan 1974 [2 Feb 1973] 03988/74 Heading H1K [Also in Division H3] An integrated structure comprises a substrate or one conductivity type forming the collector zone of a first transistor Tl (Fig. 4) an epitaxial layer of opposite type forming the base of T1, the collector zone of a second transistor T2, and a connection between them, a second epitaxial layer of the one type forming the base of trasistor T2 and zones 6, 7 formed in the epitaxial layers by diffusion constituting the emitters of the respective transistors. As described the substrate 1 has a surface layer of higher resistivity to reduce out-diffusion of impurity and the collector junction capacity of T1, and both the epitaxial layers have more highly doped surface zones to prevent formation of inversion layers and, where the emitter lies wholly within the highly doped zone, to reduce the emitter efficiency, hence preventing thyristor action in the combination of T2 and substrate. Details of the manufacture of the Fig. 4 structure are given. The second epitaxial layer may be pattern etched from a layer deposited overall or be formed by deposition through a mask. In the latter case either no deposition occurs on the masking material or the deposit is polycrystalline and removable by preferential etching. To provide the alternative planar surfaced structure of Fig. 5 a well is etched in the first epitaxial layer 23 before the diffusion to provide the highly doped surface layer 24 and deposition of the second epitaxial layer in the well. In the same semiconductor body a further transistor may be formed equivalent to T1 but of larger area and isolated therefrom by a groove extending down to the interconnected collector zones. In yet a further embodiment a separate wafer containing a pair of such transistors of differing areas and a wafer having the structure of Fig. 5 are mounted on a common substrate. Transistors T1 and T2 are in each case connected to form a Darlington amplifier which in this further embodiment forms one half of a push-pull amplifier the other half of which is formed by the pair of transistors in the separate wafer, the combined surface area of the two transistors in each wafer being the same.

Class 38(5) A device for sending impulses at predetermined intervals comprises a constant speed motor driving a pair of discs, a ball clamped between the discs and mounted in a carrier normally rotating with the discs, one disc having a recess forming a seating for the ball, a switch actuating member arranged in the path of an abutment on the carrier so as to stop the carrier and close an impulsing switch. continued rotation of the discs causing the ball to ride out of its seating and so force one disc axially to operate a reversing switch for the motor. The discs 5, 6 are carried by a tube 4 driven from the motor 2 over gearing 3. The disc 5 is fast on the tube, but disc 6 is urged to the left, Fig. 2, by a rod 10 which is acted on by a spring of a snap action reversing switch 15 over a lever 12. Three balls 16 are clamped between the discs and normally rest in recesses 18 in disc 5. The ball carrier 17 has an abutment which co-operates with the impulsing switch 20 and arrests rotation of the carrier 17, so that the disc 6 is forced to the right by balls 16 and the reversing switch 15 is actuated by the rod 10 and lever 12. When the motor reverses, the carrier 17 is carried round with the discs in the reverse direction, the balls 16 remaining out of the recesses 18 until the abutment 19 engages an adjustable stop 24 and stops the carrier 17. Further movement of the discs allows balls 16 to reenter recesses 18 and disc 6 to move to the left, with consequent reversal of switch 15. The stop 24 is an arcuate piece carried by an adjusting knob 25 which has to be depressed to disengage a clutch 28 before it can be rotated. Such depression causes a pin 31 to open contacts in the motor circuit during the adjustment. Rotation of the knob to an "off" position causes a finger 33 to engage a ramp 34 and hold the knob inwardly to retain the plunger 31 depressed and hold open said contacts. Specification 642,878 is referred to.
