Title: Improvements in the iron heads of golf clubs
IPC: A63B53/02
Filed: 1928-11-06
Abstract: 320,258. Watson, A. Nov. 6, 1928. Golf clubs.-An " iron " golfclub head 1 for use with a metal shaft 3 has a socket comprising a tapered portion 2 terminating in an integral bulged extension 6 to simulate the usual joint between an " iron " head and a wooden shaft. The outer diameter of the outer end of the socket extension 6 is approximately the same as that of a sheath 5 of enamel or other material protecting the shaft. The junction between the socket and the extension is marked by a groove 9 or a shoulder, and a series of indentations are formed on the socket so as to merge into the groove. The shaft is coloured and varnished to simulate wood.

Title: Water heating boiler
IPC: F22B13/00
Filed: 1970-07-03
Abstract: 1,263,845. Water boiler. GUSTAV OSPELT HOVALWERK A.G. 3 July, 1970 [4 July, 1969; 7 Nov., 1969], No. 32471/70. Heading F4A. In a liquid fuel or gas-fired water boiler the burner 3 projects into combustion chamber 2 which is surrounded by water-jacket 1. The combustion gases flow down to an outlet flue 5 via annular passage 4 formed between inner wall 7 of an extension 8 of the water jacket 1 and the outer corrugated wall 6 of an inner water chamber 11 connected to water jacket 1, 8. The corrugations which may be annular or helical form alternate narrower and wider portions along the path of the flue gases causing change of speed and direction, thus increasing the heat transfer to the walls 6, 7. The hollow space 9 within water chamber 11, which is sealed at the top by wall 10 and is open to flue 5, damps pressure variations in the flue gases and reduces emission of unwanted noises. A further annular flue passage may be provided within the inner water chamber 11. In a modification (Fig. 1, not shown), the inner water chamber 11 is omitted and in a further modification (Fig. 3) the corrugated wall 6 is replaced by a stack of cast iron rings (70) having annular flanges forming the alternate narrow and wide portions of the annular passage 12. The rings are bolted together and closed at the top by a transverse wall (120).

Title: Improvements in and relating to systems for detecting wheel-slip of electrically-driven vehicles
IPC: B60T8/17
Filed: 1953-11-26
Abstract: 739,147. Control of several motors. GENERAL ELECTRIC CO. Nov. 26, 1953 [Nov. 28, 1952], No. 32879/53. Class 38 (3). A system for detecting wheel-slip in a vehicle unit 150 comprises four similar tachometer generators 101-104 which are driven respectively by axles 105-108 and shunted by resistors 109-112. The negative terminals of the generators are connected to a common bus-bar 122 and the positive terminals are each joined to points 119 between pairs of rectifiers 117, 118. The coil of a control or signal relay 120 is connected across the parallel pairs of rectifiers. The arrangement is such that if the speed of one of the axles changes in relation to that of the others by a predetermined amount, the relay 120 is actuated to illuminate a signal lamp 123, indicating a locked wheel or that wheel slipping is taking place. In addition, the relay 120 may operate contacts for reducing the excitation of a supply generator for the traction motors. The unit 150 may be operated in combination with a similar vehicle unit 250, so that, if all the axles on unit 150 should slip simultaneously, the voltage of generators 101-104 is increased and current passes through rectifiers 118, the coil of relay 120, conductor 26, rectifiers 217, resistors 209-212, bus-bar 222, and through returnconductor 28. When this current reaches a predetermined value, the relay 120 is actuated to give an appropriate indication. Simultane. ous or individual slipping of the wheels of the locomotive unit 250 causes the relay 220 to respond. If the tachometer generators are of the alternating-current type, their output is rectified and capacitors 113-116 connected across resistors 109-112 to prevent false operation of the wheel-slip protective system. Each of the vehicle units carries a main battery 130, 230, and a common negative lead 27 is provided. Resistors 129, 229, are inserted between the bus-bars 122, 222, and the lead 27.

Title: Improvements in or relating to infra-red radiation detection devices
IPC: G02B23/12
Filed: 1960-09-27
Abstract: 888,556. Polarisation apparatus; detecting infra-red radiation. PHIILIPS ELECTRICAL INDUSTRIES Ltd. Sept. 27, 1960 [Sept. 30, 1959], No. 33155/60. Classes 97(1) and 97(3). An infra-red detection device, Fig. 1, comprises an element 1 of a ferro magnetic material (e.g. gadolinium) arranged in a chamber 2 of which the temperature is maintained so that the element 1 has a temperature slightly lower than the Curie point of the material of the element. The element is magnetised in a direction at right angles to its polished surface by a torroidal coil 5, and this surface is exposed substantially at right angles to polarised visible light from a source 6, and is observed by means of a device 7 including an analyser 8. In use, the analyser 8 is first rotated to suppress the visible light reflected by the element 1 so that a measure of the infra-red radiation incident on the element 1 through the window 4 can be obtained by rotation of the analyser 8 to again suppress the light reflected by the element 1, such rotation being necessary since the infra-red radiation raises the temperature of element 1 nearer to the Curie point and so gradually diminishes the ferro magnetic properties of the element. In an alternative, Fig. 2, a mosaic 11 of ferro magnetic particles of a material exhibiting the magneto-optical Kerr effect is arranged on a support 10 of a material (e.g. collodion) which is transparent to visible light and has a low thermoconductivity. The chamber 12 containing the mosaic is maintained at a temperature slightly below the Curie point of the mosaic 11 which is magnetised substantially uniformly in a direction at right angles to its surface by a toroidal magnetising coil 15. Source 6 illuminates the rear surface of the mosaic 11  with polarised visible light and the reflected light is observed through an analyser 18, which is initially adjusted so that no light is visible therethrough in the absence of infra-red radiation incident on the mosaic 11 through the window 14. When infra-red radiation is incident on the mosaic 11, there is local heating and a consequent reduction of the ferro magnetism of the mosaic and the rotation of the polarisation plane of the visible light rays diminishes so that an image appears via the analyser 18.

Title: Improvements in or relating to the steering system of a vehicle

IPC: B62D11/10
Filed: 1957-10-25
Abstract: 818,446. Steering vehicles by braking. MARSHALL SONS & CO. Ltd. Oct. 25, 1957, No. 33344/57. Classes 79(2) and 79(5)  In a vehicle in which the steering is effected by the application of independent brakes on differential half-shafts, the overall ratio of the change speed transmission is automatically lowered when one of the brakes is applied in order to meet the increased requirement of output torque. In one example of a vehicle having a hydraulic transmission with a variable displacement pump 1 connected through pipes 2, 3 to a hydraulic motor 2 driving a differential 23, the tilt angle of the pump 1 is automatically reduced when either of the brakes 10 is applied. The tilt angle is normally varied to alter the overall ratio by a lever 5 located by a releasable spring loaded pawl 13 and connected to an arm 8 of the pump through a push rod 6 which is pivotally connected to a block 10 slidably mounted in a slot 11 of the lever 5 and yieldably located by a spring 12. Steering is effected by levers 16 on each side of the vehicle which operate brake bands 17 through the rods 18. Each lever 16 has a cranked arm 27 engageable with the underside of a pad 26 on the push rod 6 so that movement of either lever 16 causes the rod 6 to move upwardly with the block 10 in the slot 11 and reduce the tilt angle of the pump 1. In a modification the arrangement may be applied to an epicyclic gearbox with overlapping friction bands the application of a brake causing the selection of a lower gear ratio.
