Title: Improvements relating to remote controls for marine power plants
IPC: B63H21/22
Filed: 1934-03-02
Abstract: 429,213. Controlling reversing-gearing. HARRISON, H. G., Onwards, Sycamore Road, Farnborough, Hampshire. March 2, 1934, No. 6679. [Class 80 (ii)] [See also Group XXXIII] A single-lever remote control apparatus for the reversing gear of a marine craft has included therein an interlocking mechanism coupled to the servomotor piston and positive stops on the engine control which prevent the engine from being speeded up until forward or reverse gear engagement is effected. Mounted on the servomotor 2 is a trunnion member 1 carrying a rod 4 upon which are adjustably disposed sleeves 8, the rod 4 is coupled by a link 7 to the servomotor links, and the sleeves 8 have chamfered inner edges. In a casing above the rod are disposed two plungers 10 also with bevelled edges under spring restraint 11 and having rods 14 coupled to a shaft 15. Upon the shaft are fingers 13 which project into the control drum 17 adjacent to a pin 20 on the cover 18. In the control casing 17 is a drum around which passes the chain 19 to the control station, and on the cover is the rod 21 which passes to the engine throttle. When a change of drive is to be effected, the rod 4 is moved by the servomotor, one or other of the plungers 10 is raised, and one or other of the fingers 13 is moved so as to obstruct movement of the pin 20 more than a distance necessary for idle running of the engine. As soon as the change has been effected, the rod 4 returns to neutral and the projections 13 are removed from the pin 20 so that further movement of the control chain 19 is possible for speeding up the engine.

Title: Improvements in or relating to forced-circulation central heating systems
Inventor: BURKE SHULDHAM ARCHIBALD
IPC: F24D19/10
Filed: 1955-03-07
Abstract: 809,781. Heating buildings by circulation of water; temperature-responsive actuating - elements. C.U.R.A. PATENTS Ltd. March 7, 1956 [March 7, 1955], No. 6690/55. Class 64(2) [Also in Group XXIX] For circulating to radiators, water from a boiler B and water from a by-pass C are passed into a flow pipe F in proportions determined by a valve D operated by a servomotor E. K. J. controlled by a bellows H subject to the mixed flow temperature and communicating with a bulb G subject to the temperature outside the house. If the temperature outside rises sufficiently, a nozzle J is closed by the action of the cates solely with the low pressure side of E (because the bellows E then communia main circulating pump A through a pipe K) so that the valve D is raised to permit less hot water to flow from the boiler B. The resulting cooler mixed flow in the pipe F causes the bellows H to open the nozzle J and thus counteract the effect of the warming of the bulb G. Adjustment of the system is by an additional bellows in the thermal system G, H, or by a screw for moving the position of the nozzle J or of its closure plate. Instead of being located in the return pipe R from the radiators, the pump A may be in the mixed flow pipe F, Fig. 2 (not shown) and in this embodiment there is a pipe, with a manuallyoperated valve, by-passing the nozzle J so that the full boiler outflow may be passed to the radiators on starting.

Title: Improvements relating to electric pick-up supports for gramophones and means for indicating the position of the needle in the record groove and to facilitate synchronousreproduction with picture projection
IPC: G11B27/13
Filed: 1928-10-22
Abstract: 324,411. Verity, C. H. Oct. 22, 1928. Divided on 318,847. Gramophones associated with kinematographs; indicating parts of records; disc records. - A pointer and scale are provided to indicate the record groove engaged at any time by a gramophone pick-up traversing the record radially, and a revolution counter driven from the turntable spindle, which may be driven from a picture projector, may be used in association with the groove indicator, the readings showing when the apparatuses are in synchronism. The pick-up 2 with a counterbalance weight 5 is mounted on a rod 4 guided on rollers 6 to traverse the record radially. A rack 10 on the travelling rod engages a pinion 16 to rotate a double-ended pointer 12 or a semicircular scale which is graduated to represent grooves in the record. The outer ring of markings represents the grooves from the outside towards the middle of the record and the inner ring of markings represents the grooves from the middle to the inner end, so that all grooves are indicated, the first portion by the longer end of the pointer and the latter portion. by the other and shorter end of the pointer. A weighted cord 20 on the pinion facilitates tracking. By using records with the starting groove always at the same distance from the centre, the indicator registers the actual groove engaged. If the revolution counter 19 is set so that its zero corresponds with the zero of the scale, observation of the two readings would disclose inaccurate positioning of the pick-up or jumping of a groove and thus facilitate setting the apparatus for synchronous working. According to the Provisional Specification, a visible or audible signal may indicate when a needle jumps a groove in the record.

Filed: 1926-03-13
Abstract: 275,683. Beaver, C. J., and Glover & Co., Ltd., W. T. March 13, 1926. Cables, machines and processes for making.- In the manufacture of multicore cables, the insulated conductors and strips of filling material are laid up in a bath of liquid insulating material, and an overlay of insulation may also be wrapped over the multicore cable within the bath. Apparatus for the manufacture of multicore cables comprises an elongated trough c, Fig. 5, containing liquid insulating material, and having a hole at each end, a laying out machine A at one end of the trough, and a receiving machine B at the other end of the trough, both being rotated on an axis in alignment with the trough but at different speeds. In the receiving machine B the haul-off drums d<2>, d<3> and the receiving drum d<4> are mounted within the rotating frame d, the drums d<2>, d<3> being gear driven, and the receiving drum being frictionally driven. The driving gear for the machines A and B is such that the axes of the supply drums b<4> for the insulated conductors, notwithstanding their composite movement are always in planes having the same relationship to a plane containing the axis of the haul.off drum. The supply drums b' and spools b<15> for the strips of filling material are mounted on end frames b<2>, b<1>, of the machine A. These trames rotate with a hollow shaft b which extends within the trough. The framework b<2>, b<1> is mounted on standards a<4>, a<5>. The supply drums b<4> are carried on frames b<3> rotating on the framework b<2>, bland driven to maintain the correct relationship with the haul-off drum by gearing b<14>, b<13>, the hollow shaft b<6>, and gearing b<12>, b<11>, b<9>, b<8>, b<7>, the latter being a fixed gear on the support a<5>. The conductors and strips of filling material pass through holes in a guide member b<5> outside the trough, then through a disc c<3>, Fig. 9, also on the shaft b and just fitting the hole c<2> at the end of the trough, and then converge to and through a laying-up die c<6>. Alternatively the laying-up die may be outside the trough. In the apparatus shown two filling- material spools b<15> serve each conductor and filling-material for the centre is fed through the hollow shaft b. An overlay insulation is applied within the trough from reels c'. Hot insulating liquid is pumped to the trough from a tank, the trough having an overflow outlet, and means are provided to keep the temperature constant. The trough is partitioned by baffles to enable the insulating material to be maintained at different temperatures in the different parts, and reference in this connection is made to Specification 182,510.

Title: Process for catalytically reforming and desulphurising hydrocarbon oils
IPC: C10G69/08
Filed: 1942-05-28
Abstract: 559,521. Purifying oils. MOND, A. L. (Universal Oil Products Co.). May 28, 1942, No. 7227. [Class 91] [Also in Group IV] In a process for the production of purified gasoline fractions of high octane rating by subjecting unrefined cracked gasolines to catalytic reforming at temperatures within the range 425-650‹C. followed by desulphurization in presence of catalysts at temperatures from 260- 425‹C., the oil leaving the reforming stage is reduced to the temperature required for the purification stage by direct admixture with a cooler oil which may be (a) an extraneous hydrocarbon fraction (2) a fraction produced in the process. The reforming and desulphurizing stages may be performed within the same reaction vessel and gases obtained in the process are preferably recycled to pass with the oils through the reaction zones. In the drawing, the crude stock is mixed with gases recycled through line 38 either before or after passage through a preheating coil 6 and is then passed downwardly through a reactor 10 packed with catalysts in layers. A second stock which requires purification only is preheated in coil 18 to the required temperature so that on the admixture of the two stocks in the reactor 10 the required desulphurization temperature is obtained. The treated mixture passes to a fractionating tower 24, gases and gazoline passing overhead to a condenser 29 and collector 32 where their separation is effected, the gases being recycled in part as described. In a modification, part of the gasoline collected in 32 is recycled through line 42 to provide the cooling oil injected into the reactor 10. Alumina, silica or magnesia composited with oxides of elements of the left hand columns of Groups IV, V, and VI are used for the reforming, and similar catalysts, bauxite or clays may be used for the desulphurization. The reforming of a straight run gasoline at a temperature of 500‹C. in presence of aluminachromia reforming catalyst, followed by purification at 400‹C. in presence of bauxite as desulphurizing catalyst is described, the necessary cooling being obtained by admixture of another gasoline heated to 315‹C.
