Title: Improvements in or relating to change speed toothed gearing
Filed: 1928-06-20
Abstract: 315,967. Carling, W. T. June 20, 1928 Facilitating changing speed. - Relates to variable-speed toothed gearing in which speed changes are effected by changing engagement of sliding gears or clutches and in which locking means are provided for preventing inopportune engagement as described in Specifications 282,121, 294,301 and 307,631. The fuel supply to the engine is automatically reduced a suitable amount so as to cause the velocity of the driving engaging gear or clutch member to be reduced more rapidly than the driven corresponding member. This reduction is effected by exciting an electromagnet 8, Fig. 3, the armature 11 of which is supported so as to have parallel motion on two cranks 4<a>, 10a. A spindle 10, Fig. 4, is part of the parallel motion, but 4 is the spindle of the valve of carburetter 1, Fig. 1. The magnet turns the spindle 4 so as to move a lever 6 away from manual control lever 2 against the pull of a spring 5. The magnet is controlled by a switch lever 15, Figs. 5 and 6, which makes contact at 16 when rocked to the right by movement of change-speed lever 12. Upon a bracket 21, the lever 12 carries two plates or ribs 22 which coact with a finger 15<c> on lever 15 to tilt the lever 15 when lever 12 is operated. In gear changing, by the time the engaging clutch or gear members meet, the engine has been slowed down sufficiently for the whole force of the explosions to be absorbed by the fly-wheel so that engagement takes place smoothly. Instead of the electromagnetic means for operating the lever 6 of Fig. 1 from the gear lever 12 of Fig. 6, mechanical means may be used. An arrangement of spring push rods is described released by ribs similar to the ribs 22 of Fig. 6.

Title: Improvements in calorimeters for central heating installations
IPC: G01K17/12
Filed: 1954-06-17
Abstract: 752,856. Measuring heat quantities. VDO. TACHOMETER WERKE A. SCHINDLING GES. June 17, 1954 [June 17, 1953], No. 17829/54. Class 97 (3). In a heat meter which measures the product of the quantity of heat carrier flowing through a heating installation and the temperature difference between its supply and discharge by means of a bladed wheel in a supply duct or a flow meter driving a counting mechanism through a liquid coupling, the bladed wheel drives an inner cylinder the rotation of which is transmitted by the coupling liquid to an outer cylinder driving the counting mechanism, and the level of liquid between the two cylinders depends on the temperature difference. As shown, hollow cylinders 2, 3 are mounted in a closed vessel 1. The inner cylinder 3 rotates in bearings 5, 6 and is fast with a magnet 8 driven by a magnet 15 outside vessel 1 which is driven by the bladed wheel. The outer cylinder 2 is free to rotate coaxially with cylinder 3 and is geared to counting mechanism 13. Vessel 1 communicates with a vessel 17 so that a liquid 16 may flow from one to the other. The vessels 17, 1 are respectively connected by pipes 18, 19 to closed air chambers in contact with the supply and discharge ducts of the installation. When there is no temperature difference, the liquid in the two vessels has a common level 0 at the lower end of cylinder 3. When heat is drawn off, liquid is forced into vessel 1 and enters the space between cylinders 2, 3 through apertures 20 in cylinder 2. The degree of coupling between the cylinders depends on the height of liquid h above the bottom of cylinder 3, and the speed of rotation of cylinder 2 is thus dependent on the speed of cylinder 3, which in turn depends on the rate of flow of heat carrier, and on the height h, which depends on the temperature difference between supply and discharge. To render the degree of coupling between the cylinders strictly proportional to the temperature difference, the cross-sectionof one of the vessels 1, 17 is varied axially, the spacing between the cylinders is varied axially, or the spacing between cylinder 2 and a braking sleeve 21 introduced into vessel 1 is varied axially.

Title: Improvements in or relating to edge-illuminated display devices
IPC: F21V8/00
Filed: 1947-07-08
Abstract: 639,667. Changing signs. PARKER, R., and BOODSON, N. July 8, 1947, Nos. 17950, 25119 and 28074. [Classes 3(i) and 3(ii)] A number of edge-illuminated superposed sheets 13-17 each having a different display on a face are illuminated by a light beam of less width than the overall width of the superposed sheets, the beam being variable in position to illuminate a number of sheets in turn at the same time leaving one or more sheets unilluminated so as to display a succession of different images. The sheets 13-17 are mounted on a base 10 by means of a frame 12. Sheets 13-16 are transparent and sheet 17 may be either transparent or translucent. Behind sheet 17 is an opaque backing sheet 18. Each of the sheets 13-17 is recessed on the back with part of a design so that an animated effect is obtained by selective illumination of the sheets. Sheet 13 is continuously edgeilluminated by a plurality of lamps 20 which are contained in an opaque chamber in the base 10; a partition 21 preventing light reaching the other sheets. Mounted below the other sheets is a tubular lamp 22 which is surmounted by a collimator 23, the light from which is directed onto the edge of each of the sheets 14-17 in turn by a square section prism 25 continuously rotated by an electric motor 31. The collimator beam is sufficiently narrow to ensure that only one sheet is illuminated at a time. The prism may have any even number of sides and be oscillated instead of rotated. The edges of the sheets, the light source or the recesses in the sheets may be variously coloured. The sheets may be illuminated by daylight by means of mirrors if desired. In a modification, two sheets only are used one of which is continuously lit and the other intermittently by means of a motor-driven switch.

Title: Improvements in flash-light apparatus
IPC: B61L5/18
Filed: 1937-06-28
Abstract: 479,266. Railway signals. BORMANN, O. June 28, 1937, Nos. 17981, 17982, 17983, and 17984. Convention dates, June 26, 1936, Oct. 3, 1936, Oct. 28, 1936, and Dec. 31, 1936. [Class 105] [Also in Group XI] In a flash-light signal lamp the shutter 4 is operated by the pressure of gas in a pipe 7 in shunt with the main pipe 8 leading to the burner 3. The gas employed may be propane, butane, or like liquefiable gas, or it may be a gas which can be compressed under high pressure. The operating means may comprise a motor 6, the diaphragm 19 of which is connected by a rod 11 to a parallelogram device 5 attached to the shutter 4. Gas issuing from the outlet 9 of the motor 6 is led by a pipe 12 either out into the air or back to the main pipe 8, and the ratio between lighting time and dark time is controlled by regulating screws 13 on the pipes 7 and 12. A spring, or a weight 14, may be provided to free' the shutter from the light source when the gas supply is cut off from the motor so as to change from a flashing light to a steady light. In addition, a three-way cock 15 may be operated by an arm 17, connected, for example, to a signal arm or to railway points, whereby gas inside the motor can escape through a pipe 16. In the three-position signal shown in Fig. 3, the spectacle 20, which is coupled to the signal arm 27, is formed with a slide, consisting of an arcshaped part 30 and a rectilinear part 31, adapted to control a fork 29 connected to the stopping device. By this means the fork is not moved when changing between green steady light (disc 23) and red steady light (disc 22), but only when changing between red steady light and yellow flashing light (disc 21). To ensure that the stopping device is operated in the middle of such movement, the fork 29 may operate a rod 32, Fig. 4, against the action of a spring 35, the rod having a bevelled end which engages the head 33 of a stop valve. To avoid waste of gas, the reversal of the valve may be effected instantaneously by providing the rod 32 with a slide 36 of the form shown in Fig. 5, this slide engaging one end of a double lever 37, the other end of which engages a two-position blade spring 38 which operates the valve rod 39. A diaphragm 40 provides a gas-tight joint. The use of a cock or valve can be entirely avoided if the bevelled end of the rod 32 is arranged to engage an abutment on the rod 11 of the motor. Fig. 7 shows modified means for changing from steady light to flash light. In this form the piston rod 11 bears against a two-armed lever 44 pivoted at 43 and controlled at one end by a spring 46. The other end 47 is connected by a lever 48 to the parallelogram device 5 and carries a ramp tappet 49 adapted to be operated by the rod 32.

Convention date, June 27, 1931. Addition to 384,793. [Class 2 (ii).] The process described in the parent Specification, for extruding a highly concentrated solution of a cellulose ester and/or ether through an annular orifice into an evaporative medium whilst simultaneously air or other gas and a thread-like inlay are introduced through a bore or bores within the annular orifice, is modified by using a solution containing sufficient softening agent to leave at least about 28 per cent in the finished bodies. Hollow strips, bands, &c. may be made by using an elongated annular discharge orifice. The products are particularly useful for working up on the usual braiding machines into braids or laces. In an example there is used a solution containing 39 per cent of cellulose acetate and 31 per cent of a softener comprising one-third each of triacetin, triphenylphosphate, and tricresylphosphate.

Abstract: 439,672. Control of motors. FORREST, P. W., 1783, Shettleston Road, Shettleston, Glasgow. June 24, 1935, No. 18026. [Class 38 (iii)] Travelling to predetermined limits.-An automatic control system for a motor 15 operating through successive predetermined distances, includes a series of thermostatic switch elements 1, 1<1>, 1<2>, each of which is co-operative with a pair of spaced contacts so as to control automatically the successive restarting of the motor, the contacts 4, 5, against which the first two elements 1, 1<1> of the series normally rest being electrically interconnected. Upon closure of a switch 8 the circuit of the motor 15 is completed over contacts 22, and the heating coil 2 of element 1 is energized. The element 1 moves into engagement with a contact 4<1> and out of engagement with the contact 4, the motor circuit being maintained by the interconnection of contacts 4, 5. After a predetermined operation contacts 22 are opened by the motor, and the motor stops. The heating coil 2<1> of the element 1<1> is energized by the closure of contacts 4<1>, and when the element 1<1> contacts with the contact 5<1>, the motor circuit is again completed over contacts 22<1>. The disengagement of the contact 5 causes the deenergization of the heating coil of element 1 which moves to its original position. Similarly, when the motor stops after operating a further predetermined distance and opening contacts 22<1>, it is restarted by the element 1<2>, the cycle of operation being continually repeated while the switch 8 is closed. In a modification, Fig. 2, not shown, two thermostatic switch elements only are provided. Specification 428,809, [Group XVIII], is referred to.
