Title: Synchronous Alternating Liquid Current Motors.
Inventor: CONSTANTINESCO GOGU
IPC: F16H43/02
Filed: 1916-10-03
Abstract: 110,005. Constantinesco, G., and Haddon, W. Oct. 3, 1916 Hydraulic transmission of power; liquid-pressure engines.-Relates to hydraulic motors for use with an hydraulic transmission system of the type described in Specification 9029/13, and consists of a motor that may be driven at a different speed from that of the generator. In one form, the motor consists of a number of radial cylinders 1, 2, 3, Fig. 2, provided with ball pistons c arranged round a cam a mounted on the shaft b. The cam is formed with five projections of such a form that each piston receives an harmonic displacement having a frequency five times as great as the number of revolutions of the shaft b. Five cams such as a are mounted on the shaft band co-operate with five sets of radial pistons, the whole being contained in a casing. The three groups of cylinders 1, 2, and 3 are connected to three supply pipes, in which the phase differs by 120 degrees, and a reversing-valve, such as that described in Specification 1511/14, may be provided. In Fig. 3, the manner of connecting the motor a to a generator o is shown. A reversing- valve is shown at g, and cut-off valves at k. Rise of pressure on closing the valves k is prevented by the insertion of condensers h: or alternatively, capacities such as described in Specification 4349/15 may be used. The three transmission pipes may be connected by three small-bore pipes l to a common point m, which is at constant pressure. Liquid may be forced into the system at this point to compensate for leakage. In the modification shown in Fig. 4, the cylinders are arranged axially, and their pistons c co-operate with a plate a having a rim of undulating section. In another modification, the plate a may be provided with a thrust bearing. and the cylinders arranged on one side only. Motors such as described above are equally applicable as generators, so that, by combining a suitable generator and receiver, any desired speed ratio may be obtained. The invention is applicable to the gearing down of high-speed turbines to low-speed propellers. Specifications 12438/14 and 106,309 are also referred to,

Title: Adjustable engine brake
IPC: F01L13/00
Filed: 1963-04-09
Abstract: 1,002,475. Regulating I.C. engines; I.C. engine braking. F. FINGER. April 9, 1963 [April 19, 1962], No. 14078/63. Headings FIB and F1K. [Also in Division B7] An I.C. engine brake valve which allows the charge to escape from each cylinder during the compression stroke is adapted to be inserted into an opening for a spark or glow plug provided in the cylinder head 3, Fig. 1, and to receive a spark or glow plug 1. The brake valve is brought into operation by rotating a cable pulley 32 connected to tubular member 29 against the action of spring 23 to rotate control ring 19 until it engages in corresponding recesses in stationary control ring 20. Pressure rise in the cylinder causes bushing 7 to rise off the valve seat 4 and then annular piston 10 to rise against the action of spring 11 allowing the charge to exhaust through the gaps between bars 12, ports 14 and into an exhaust receiver and silencer 36, acted on by spring 38 and thence to atmosphere. Pulley 32 carries a Bowden cable 39 and housings 22 and 49 are locked together by spring-loaded pin 25. The spark plug electrodes 2 are removable. Figure 6. When the vehicle accelerator pedal 66 is pivoted in direction of arrow 86 beyond a neutral position arm 51b is pivoted to cause valve 50 to connect an air intake pipe 55 with a pipe 56 leading to a vacuum servo means which actuates the engine brake. When clutch pedal 60 is depressed projection 61 pivots arm 51a to connect pipe 56 with pipe 54 leading to the outside thus causing the vacuum servo means to return to its neutral position. Simultaneously with actuation of the bell crank a Bowden cable 58 actuates a switch to break the connection to the primary circuit of the ignition or in a modification the Bowden cable may control the brake valve directly. In another embodiment the oil pressure line for the normal vehicle brakes is tapped off to operate the engine brake through a hydraulic cylinder. Figure 9. When knob 110 draws the Bowden cable in the direction of arrow 111, valve 94 closes opening 93. Outlet 98 is connected to the engine air intake duct through a valve (not shown) so that a vacuum is produced in chamber 92 whereby diaphragm 91 and part 95 connected by cable 96 to the pulley 32 are moved in the direction of arrow 97, the braking effect thus being variable in dependence on the setting of knob 110. In a modification the knob is replaced by a hand lever provided with a ratchet means. The servo means may consist of an electric motor or may be vacuum-controlled or controlled by oil or pneumatic pressure or adjusted directly by electrical controls. In a further modification, a by-pass valve, controlled conjointly with the engine brake, is inserted in the air intake duct of a carburetter engine and operates to by-pass air round the carburetter during engine braking, thus cutting off the fuel supply.

Title: Improvements in or relating to automatic grinding wheel adjustment for rotary table flat-grinding machines
IPC: B24B49/04
Filed: 1952-06-04
Abstract: 732,056. Grinding. KRUG, C. June 4, 1952 [Sept. 28, 1951], No. 14158/52. Class 60. An automatic grinding-wheel adjusting means for rotary table flat grinding machines is characterized in that the rotary table is provided with means to make and break an electric circuit between a grinding-wheel adjusting mechanism and a feeler-gauge actuated by oversize workpieces, so that displacement of said feeler-gauge can only effect operation of the grinding wheel adjusting mechanism when said rotary table is in a position to close said circuit. A rotatable work-table AT carries workpieces W beneath a grinding-wheel S. Spaced contacts K on the table AT co-operate with a brush 8 joined to line 101, the contacts being interconnected and joined to line 102. The circuit from line Q to line R of the mains is thus closed, when brush 8 registers with a contact K, to energize the coil of relay RW. If the feelergauge T is lifted by a workpiece W which is oversize, due to wear of the grinding-wheel, an electric current is transmitted from a current source la by way of line 1, contacts in relay RW and line 2 (thus energizing coil of relay RT2) to contacts in closed relay RT1. Current is then transmitted through line 3 to contacts in closed relay RT2 and via line 4 to operate feeding relay FR thereby energizing through lines 5, 6 an electromagnet M actuating the grinding-wheel adjusting mechanism. When brush 8 leaves contact K, relay RW returns to its non-energized position so that current will flow through line 10 to energize coil of relay RT1 and thereby open contacts of relay RT1. Coil of relay RT2 is de-energized and contacts of relay RT2 opened whereby electromagnet M is cut out of circuit and the grinding-wheel adjusting mechanism rendered inoperative. The distance between contacts K is somewhat greater than that between the gauge T and the grinding wheel S. The grinding-wheel adjusting mechanism B comprises a rotary-vane type hydraulic motor controlled by a valve operated by the electromagnet M; the rotational displacement of the vane is converted into linear motion, e.g. by worm and screw spindle drive. A switching mechanism may be provided to break the circuit between the gauge and electromagnet M despite the position of the brush 8 and contacts K.
