Patent GB-198490-A (GB)
Title: Improvements in or relating to lappet mechanism for looms
IPC: D03D31/00
Filed: 1922-03-24
Abstract: 198,490. Whitehead, H. P. March 24, 1922. Lappet looms.-The lappet wheel A, Figs. 1 and 4, has two or more operating grooves A<1>, A<2>, Figs. 1, 3 and 4, for the peck or pin B on the dummy bar D supporting the needle-bar, and automatic or other means are used to shift the peck &c. from one operating-groove to another whilst the loom is running, so as to change the pattern. The operating-grooves are connected by means of one or more communicating grooves A<3>, provided with a pivoted pawl C controlled by a spring C', which pawl, however, is normally depressed by the peck &c. when it passes along, owing to the stronger spring E and the peck continues in or enters the groove A<2>. A ratchetwheel H<1> provided with teeth is secured to the lappet wheel and is rotated by a pawl J as the lappet wheel rotates, and a cam H on the ratchetwheel controls a spring G furnished with a pin F, which is thus caused at times to project behind the pawl C and prevent it from being depressed, so that the peck is caused to move into the outer groove A<1>. The pawl J may be thrown into and out of operation by trip mechanism. The ratchetwheel or cam may carry stops &c. H<2> to engage and actuate a part K of a pull-off lever K<1> so that breaks in the pattern may be caused to occur after one or more revolutions of the lappet wheel. The lever K<1> is connected by a wire M<3> to a member M. which normally supports one end of a lever N, N<1> carried by a lever Q. When this lever is moved it normally causes the lever N, N<1> to raise a member O and the needle bar L; but when the lever K<1> is operated, the member M is rocked against the action of a spring M<2>, so that it no longer supports the lever N, N<1> and movement of the lever Q then causes the lever N, N<1> to swing idly without moving the needle bar, whereby a gap or break in the pattern is produced. Two pivoted members, or where there are more than two grooves, a series of pivoted members, or a single member movable into several positions, may be used.

Abstract: 830,259. Turbine plant. SIEMENS-SCHUCKERTWERKE A.G. March 20, 1956, No. 8744/56. Class 110 (3). [Also in Group XXXV] In an electric power plant of the kind in which a single boiler and an associated turbine form a driving unit for a generator, an output signal related to the frequency is produced by manually or automatically-operated apparatus for regulating the output frequency of the generator to control simultaneously the speed of the turbine and the output of the boiler, and the boiler output is additionally controlled to keep the steam pressure substantially constant by a control signal produced in dependence on the steam pressure. A signal Xf proportional to the measured generator frequency Mf is applied with a reference signal Wf to a frequency retulator Rf and the resulting signal Yf produced is applied simultaneously to a turbine speed adjusting device MT and a motor ML driving a boiler output controlling means STLa which regulates the supply of fuel air and feedwater to the boiler. Pressure regulation in response to signal XD from a piston manometer KO is effected via a regulator RD a motor MD and a differential gear G. Manual regulators H1-H3 to obtain the desired working conditions are also provided. The system may be adapted for sliding pressure working by the introduction of a cam K which imparts a reference value WD to the pressure regulator.

Abstract: 855,771. Knitting-machines. MONK (SUTTON IN ASHFIELD) Ltd., S. A., MONK, S. A., and MONK, B. A. June 3, 1959 [March 25, 1958], No. 9455/58. Drawings to Specification. Class 74 (2). A control drum having studs or cam lifts is provided in a straight-bar machine and is racked a single complete revolution on the completion of a garment or part thereof so as to actuate in sequence switches controlling the electric motors and solenoids for the various components of the machine whereby the components are actuated or returned to their initial position preparatory to the commencement of normal knitting of the next garment or part thereof. For this purpose the presser arm truck may be so actuated to enable a slack course to be produced followed by actuation of marking points. The machine is then operated by an auxiliary slow-speed motor and the carriage bar is disengaged from its drive. The fashioning screws are then returned to their initial setting as described in Specification 855,772, and simultaneously a yarn deflector is operated to position the yarn for engagement by the sinkers on commencement of knitting. Welt transfer mechanism for example as described in Specification 852,478 is then operated whereafter the machine commences normal knitting, the drum having completed a single revolution. Pawl and ratchet mechanism is employed to rotate the drum and is itself controlled by stop mechanism which ensures that the carrier is at its correct end of the machine prior to the commencement of racking of the drum.

Title: Hot-gas engine
IPC: F02G1/047
Filed: 1972-03-01
Abstract: 1383815 Hot gas engines; controlling airfuel ratio PHILIPS' GLOEILAMPENFABRIEKEN NV 1 March 1972 [4 March 1971] 9485/72 Headings F1C and F1S [Also in Division F2] A hot gas engine comprises a heater 10 heated by a burner 14 having an inlet 16 for combustion air supplied by blower 21 and a fuel inlet 15 to which fuel is supplied by pump 20 via fuel supply duct 24, the blower 21 whose output is directly proportional to its speed and the pump 20, whose output is proportional to its speed above a given speed being coupled and having their speeds controlled by a heater temperature responsive device 18. A pressure control valve 27 maintains in operation a substantially constant pressure at the pump outlet and fuel is only permitted to flow from the pump to the burner when this pressure has been reached. A fuel return duct 25 with a restriction 29, is provided. Fuel may be supplied by a viscosity metering pump, Fig. 3, in which fuel passes through inlets 60, 61 to ducts 48', 49', which communicate with pumping grooves 43, 44 along which fuel passes, due to rotation of the pump rotor, to grooves 50, 51 and thence to duct 45 and outlet 53. The grooves may be formed instead in the cylinder 52. The pump may be used for liquid or gaseous fuel. The presence of valve 27 ensures that a higher pressure is imposed on the outlet of the pump than in the absence of the valve causing a "virtual leakage" of fuel reducing the pump's output. The valve shown in Fig. 4 has a relatively large area of diaphragm 74 subject to pressure in inlet chamber 71 and a relatively small area subject to pressure in the outlet chamber 72 so that variation of pressure in the latter has little influence on the pressure in the inlet chamber.

Title: Improvements in or relating to the Cooking of Meat.
Inventor: VERDON HENRY WALTER
IPC: A23L13/00
Filed: 1916-07-08
Abstract: 107,800. Verdon, H. W. July 8, 1916. Grilling-sloves.-Grilling is performed by holding the meat, such as a chop, in a flame produced by burning fat. In the arrangement shown, a tray C having a central raised slightly-hollowed " table " D, supports a gas ring A, the jets of which heat a plate B in which holes are punched from beneath so as to produce burrs on its upper surface to retain a film of grease thereon. The chop &c. is held vertically, by means of a toasting fork above the plate B, and the fat end is brought down so as to touch the plate, whereby some fat drips off and is ignited by air passing upwards through the perforations. The flame thus envelopes the meat, and is maintained by more of the fat melting and igniting. If the amount of fat is insufficient, additional fat may be skewered to the meat, or liquid fat of any kind may be sprayed on the plate B. Any fat which passes through the perforations without igniting is caught by the table D and spreading as a thin layer is ignited thereon. The plate B may be heated by any other means such as by electricity or by coal.
