Title: Improvements in or relating to telegraph apparatus
IPC: G08B9/08
Filed: 1943-08-21
Abstract: 569,057. Ships' telegraphs. CHADBURNS (LIVERPOOL), Ltd., [formerly CHADBURN'S (SHIP) TELEGRAPH CO., Ltd.], and PIGOTT, S. T. Aug. 21, 1943, No. 13659. [Class 118 (ii)] The indicator of a remote control telegraph transmitter or receiver is arranged to move with linear motion over the dial. As shown in Fig. 2, for a ship's telegraph transmitter, the spiral gear 16 which is keyed to a shaft 14 carrying a handle 13, rotates the vertical secondary spiral gear 17 driving the output shaft 18. A helix 20, mounted on an extension of the shaft 18, co-operates with a peg wheel 22, thereby giving a step-by-step motion to an indicator 28 mounted on a chain 25 and driven over sprocket wheels 26 and 27 by a sprocket wheel 24 which is mounted on the same shaft as the peg wheel 22. In the receiver, Fig. 6, the peg wheel 34 mounted on a shaft 33 which is connected by shafting to the output shaft 18 of the transmitter, transmits a step-by-step motion to an indicator mounted on a chain 40, through a star wheel (not shown) and a peg wheel 36 keyed on a shaft 38 axially with the shaft 33. In a modification, Fig. 4 (not shown), the position of the indicator may be definitely located in both the transmitter and the receiver by means of a crown wheel keyed on the shaft' 14 and axially spring pressed so that its teeth engage those of a coaxial fixed wheel and ride over them tooth-by-tooth at each adjustment. In another modification, Fig. 13 (not shown), the extension to the shaft 18 drives, through a skew-gearing, a screw threaded through a block carrying the index so that the block traverses the length of the screw. The dial of the transmitter may be inclined upwardly and backwardly and that of the receiver downwardly and backwardly. Specification 569,058 is referred to.

Title: An Improved Solid Fuel.
Inventor: BOWEN RICHARD
IPC: C10L5/38
Filed: 1916-09-30
Abstract: 109,995. Bowen, R. Sept. 30, 1916. Composition fuel.-Artificial fuel is produced in the form of stratified blocks, the layers of each block being treated to prevent them from adhering together perfectly when hot. This may be done by cooling the tace of each layer by a fan, compressed air, or water spray before applying a second layer, or by treating each layer with lime, coke dust, or other powder which may be applied as a spray. The fuel is made from waste coal, coke, wood dust, &c., to which volatile substances, hydrocarbons, &c., are added, an analysis of the material forming the basis of the fuel first being made to determine the amount of volatile matter necessary. The waste materials are then mixed and heated in a covered pan, the volatile substances being melted by superheated steam &c. in an adjoining closed chamber. These substances when melted are injected under pressure with the steam into the vessel containing the waste materials; they are then withdrawn and rolled into sheets which are treated as described above and superposed to form a block. When cold, the block may be broken into lumps. In an example, the first-mentioned vessel contains 8 parts coal, 10 parts of partly calcined ashes or coke, and 5 parts oolitic dust or other lime-producing dust, the second or steam-vessel containing 2 parts tar or pitch, ¢ part naphthalene, “ to ¢ part creosote. In a modified process, the materials are moulded into blocks, the materials being inserted into the mould in layers treated as described above. In another modification, all the waste products and the volatile substances are heated together in a closed chamber, the mixed materials being inserted in layers which are separately compressed and treated with lime, coke dust, or other powder to prevent complete adhesion. The materials may be heated only sufficiently to cause them to combine partially, further combination being produced when the fuel is burnt.

Material; e.g. quarried rock, loaded into the open top of a hopper 10, is discharged through an open end 12 by a reciprocable box-like pusher member 19 whose rear edge 19a, when the pusher 19 makes its feeding stroke, does not pass beyond the edge 14a of an end wall 14. The pusher 19 is reciprocated cyclically by a double-acting hydraulic ram 20 under the control of a unit 23, 24. The provision of two inclined sides 13, 14 and a vertical side 15 avoids " bridging " of material. A portion of the base is in the form of a screen 17 for " fines." The ram 20 may be controlled manually or by automatic valve means. A member over the opening 12 may limit the size of discharged material. The apparatus is also suitable for the processing of materials used in the food industry.

Title: Apparatus for pulling back ordnance or for use as a lifting jack or the like
IPC: B66F3/24
Filed: 1942-10-07
Abstract: 561,270. Jacks. COOK, C. Oct. 7, 1942, No. 14075. [Class 78 (iii)] A hydraulic jack, which can be employed also for testing springs, e.g. the recoil springs of ordnance, comprises a cylinder head A having an internally and externally threaded flange B on which are screwed the cylinder C<2> and its jacket casing C<1>. In the head A is located a pump bore F in which slides a ram F<1> pressed upward by a spring F<4>. The ram is actuated by a handle F<2> carrying a cam F<3> which bears on the head of the ram, or alternatively by a cam rotated by an electric motor. The lower end of the bore F is connected to the base of a parallel valve bore containing a spring - pressed one - way ball valve, and, optionally, fitted at the top with a pressure gauge. From above the ball a duct leads to a rotary valve H<2> from which leads a duct H<7> to the top of the piston D and a duct H<6> to the underside of the piston, by way of an outside tube G<2>. The lower end of the bore F is connected also by way of a duct H<3> to the liquid reservoir C<x> located between the two cylinders C<1>, C<2>, a suction valve being disposed in the duct at H<1> or other suitable place. A hand-adjustable valve V connects the reservoir C<x> and the interior of the cylinder C<2>. When used as a jack, the valve H<2> is turned to allow of passage through from the valve bore to the duct H7, the valve V being opened to allow of displacement of liquid beneath the piston D into the reservoir C<x>. To retract the piston, as for spring testing, the valve H<2> is turned to connect the valve bore with duct H<6> and pipe G<2>. The fluid in top end of cylinder escapes to the reservoir C<x> during this operation by way of a passage from duct H<1> to the cylinder top. A snifter valve may be provided on the filling plug W to release any accumulation of air in the. reservoir C<x>. A suitable adaptor can be fitted in the head for topping-up purposes.

In a mass spectrometer with an electron beam bombardment ion source operated in the socalled "space charge working condition" wherein i e /bE z0 >10<SP>-4</SP>A/V, i e  being the ionizing electron current, b the breadth of the sheet-like electron beam and E z0  the potential gradient due to the ion extraction voltage, the electron beam is pulsed to reduce the time of retention of the ions in the potential wall due to the electron space charge. The conditions may be such that the ion retention time is only dependent on the gas pressure which may be, e.g. below 10<SP>-9</SP> Torr. Rectangular blocking voltage pulses of pulse ratio 1 : 1 are applied to a control electrode provided between the thermionic cathode of the electron beam and the box-type ionization chamber.

Abstract: 101,721. Pel, J. Oct. 6, 1915, [Convention date]. Film evaporators.-The paste or batter for making wafer papers for medicinal use is pumped up to an open - bottomed trough 6, arranged above two steam - heated cylinders 1, 2 and provided with a rapidly rotating bar 7 having a flat brush 8 along one edge. The paste is distributed by the brush to the surfaces of the two cylinders, a little paste also resting in the angle between the cylinders. Steam inlet and outlet pipes 4 pass through the trunnions. The cylinders are rotated in opposite directions and carry the two sheets downwards whilst they are being dried by the heat. Below the line of contact of the two cylinders, a roller 12, carried by adjustable pivoted rods 15, presses the two sheets against one another and against one of the cylinders, for example against the cylinder 1, while an air blast is directed against the entire sheet by a pipe 20 having a conical nozzle. By this means, the steam is driven off and the two sheets are united by the pressure. In a modification, a thin endless band 21, Fig. 4, passes around one of the cylinders and over a guide-roller 22 to cause the two layers to adhere. In each arrangement, sheets up to one metre in width may be obtained.
