Title: Improvements in and relating to route-indicators for vehicles
IPC: G09B29/06
Filed: 1965-10-05
Abstract: 1,076,348. Route-indicators. H.V. McMORRAN. April 21, 1966 [Oct. 5, 1965], No.42222/65. Heading G1K. A route indicator on a vehicle comprises a drawer 4, Fig. 4, which can be withdrawn from a frame 1 secured to the vehicle dash board and in the drawer 4 a strip 10, showing a pre-selected route, extending between spaced rollers 8, 9 and driven in accordance with the vehicle's progress. The strip 10, Fig,. 3, is driven from the speedometer drive by a pinion 21 meshing with another 17 which through a hollow shaft 18 and spring urged spindle 19 drives a friction disc 23 which drives a disc 22 on the shaft of the spool 9 through discs 25 carried by a sleeve 24. As the diameter of the roll of the strip 10 on the spool 9 increases a roller 29 on a bracket lifts a slide 27 carrying the sleeve 24 and by moving the discs 25 nearer the centres of the discs 22, 23 reduces the angular speed of the spool to keep the linear speed of the strip 10 constant. The reduction ratio in the drive from the speedometer is selected to suit the scale of the route map. The drawer 4 has a side door to facilitate changing the strips and a front door 5 fitted with a viewing lens. Illumination is provided from the rear. An index mark or scale is provided on a strip 34 adjustable across the strip 10 by a knobbed spindle 37. The strip may have perforations for actuating spring strip contacts to give warnings and/or to switch on a tape recorder reproducer to provide a commentary on the route.

Title: Improvements in or relating to electric power supply apparatus for deriving a relatively high d.c. voltage from a source of relatively low d.c. voltage
IPC: H02M3/338
Filed: 1964-10-16
Abstract: 1,021,169. Automatic voltage control. HONEYWELL Inc. Oct. 16, 1964 [Oct.18, 1963], No. 42244/64. Heading G3R. [Also in Divisions H2 and H3] In a D.C. to D.C. converter for charging an electronic-flash capacitor 13, the operation of the transistor oscillator circuit is changed from a relaxation mode of oscillation to a class A mode when the voltage on the capacitor rises above a predetermined level by the inclusion in the oscillator regenerative feedback path of a network 38 whose impedance is changed from a low to a high impedance state in response to the said voltage rise. As shown, the network 38 includes a silicon controlled switch 50 which is normally maintained conducting by a positive voltage on its gate 53. The circuit oscillations generate the gate voltage across a Zener diode 57 and capacitor 60, and generate the switch drive voltage across a capacitor 56. With switch 50 conducting, the network 38 is in its low impedance state and results in the relaxation mode of oscillation in which the core of the oscillator transformer 27 saturates. When the voltage on capacitor 13 reaches a predetermined level, a neon 66 strikes and causes a negative voltage to be applied to the gate 53 of switch 50 to turn the switch off. The network 38 then presents a high impedance to the oscillator regenerative feedback current and results in a low power output class A operation of the oscillator until the voltage on capacitor 13 falls sufficiently for neon 66 to extinguish. The silicon controlled switch 50 may be replaced by a selected silicon controlled rectifier or other known switching element.

Filed: 1965-10-12
Abstract: 1,068,209. Rotary-piston L C. engines. ROLLS-ROYCE Ltd. Oct. 12, 1965, No. 43201/65. Heading F1F. A rotary-piston I. C. engine comprises in a common casing 10, Fig. 1, a first unit having a three-sided planetary rotatable piston 11 sealingly engaging an inner peripheral wall 14 of doublelobed epitrochoidal profile, a second unit having a two-sided planetary rotatable piston 12 sealingly engaging an inner peripheral wall 22 of singlelobed epitrochoidal profile and a third unit also having a two-sided planetary rotatable piston 13 sealingly engaging an inner peripheral wall 23 of single-lobed epitrochoidal profile. The units are arranged co-planar in the casing with parallel shafts 16, 27, 28 on which the pistons 11, 12, 13 are eccentrically mounted with the pistons interconnected by gearing 17, 32, 33, 34 to drive a common output shaft 35. Air is admitted to the second unit through a port 53 and on rotation of the piston 12 is compressed between the pistons 11, 12 and their respective walls. It is then transferred through a duct 36 which is kept as short as possible to the first unit wherein it is further compressed by rotation of the piston 11. On completion of compression, where a side of the piston 11 is opposite to fuel-injectors 20 and spark-plugs 21, fuel is injected into the first unit and the gaseous mixture is ignited and expanded until the leading edge of the said side of the piston uncovers an exhaust port 50. The gaseous mixture is then transferred through a duct 37 which also is kept as short as possible to the third unit wherein further expansion takes place between the pistons 11, 13 and their respective walls until the opening of a port 54 through which the spent gases are finally expelled. The volumetric compression and expansion ratios are preferably substantially the same in which case the second and third units are identical. Alternatively the expansion ratio may be greater, e.g., 25 to 1, than the compression ratio, e.g., 18 to 1, so that the gases are expanded substantially to atmospheric pressure. The eccentrics on which the pistons are mounted are preferably positioned with respect to each other so that the piston 12 leads the piston 11 by 30‹ and the piston 13 lags the piston 11 by 30‹ with the ports 49.... 54 positioned accordingly. The engine achieves high compression and expansion ratios whilst still maintaining a compact and efficient combustion chamber which in part is formed in turn by recesses 17 on the sides of the threesided piston 11.

Abstract: 1,108,020. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 15 Oct., 1965 [30 Oct., 1964], No. 44461/64. Heading G6C. [Also in Division F2] A fuel element assembly includes two subassemblies attached together in end-to-end relationship by a releasable coupling comprising two interengaging members, the engagement of which is disengageably secured by a locking member, and differentially thermally expanding securing means for resisting disengagement of the locking member from the interengaging members under operational conditions in a nuclear reactor. One such assembly comprises a non-fissile sub-assembly and a fuel-bearing sub-assembly. The non-fissile sub-assembly includes a seal plug for closing an upper access opening of a reactor fuel channel and a neutron shield plug which is carried below the seal plug by a tubular member. The fuel-bearing subassembly includes a cluster of spaced parallel, end-supported fuel rods. The releasable coupling 8 connecting the two sub-assemblies comprises, as shown in Fig. 2, a shaft 9 and a sleeve 11 having interengaging splines arranged so that the shaft 9 can be engaged by the sleeve 11 by relative longitudinally axial movement and secured against longitudinally axial disengagement by limited angular movement. The looking member comprises a splined locking collar 13 longitudinally slidable on the shaft 9 and having longitudinally axial projections 34 for engagement with complementary recesses in the sleeve 11 so as to prevent further relative angular movement of the sleeve 11 and the shaft 9 when these are longitudinally axially and angularly engaged. A spring 35 interposed between the end of the shield plug 4 and a flange 36 on the collar 13 urges the projections 34 into engagement with the recesses in the sleeve 11. The shaft 9 is of a material, e.g. 18/8 stainless steel, having a higher coefficient of linear thermal expansion than the material, e.g. stainless iron, of the collar 13 to provide the differentially thermally expanding securing means. the diametral dimension over the splines of the shaft 9 and the complementary dimension of the collar 13 are such that there is a clearance fit at atmospheric temperature and an interference fit at the operating temperature of the fuel element channel. The sleeve 11 is also of stainless iron and has proportions relative to the shaft 9 such that at atmospheric temperature the shaft 9 and the sleeve 11 are relatively freely sliding to effect engagement of the coupling while at the operating temperature the sleeve 11 makes an interference fit with the shaft 9. These interference fits of the collar 13 and sleeve 11 with the shaft 9 provide additional locking means whereby disconnection of the coupling by coolant and vibration is resisted.
