Title: Improvements in or relating to the charging of multi-cylinder two-stroke cycle internal combustion engines
IPC: F02B25/00
Filed: 1944-06-14
Abstract: 581,216. Two-stroke engines. CROSSLEY BROS., Ltd., and CARTER, H. D. June 14, 1944, No. 11375. [Class 7 (ii)] In a multi-cylinder two-stroke engine the fundamental exhaust pressure pulse from one cylinder is controlled so that it reaches its peak a little before the closing of the exhaust port of a cylinder which has previously exhausted, the charging pressure being thus increased. The control may be effected by varying the control timing, or the length or bore of the exhaust conduits or by combination of these variables. In the Fig. the lines O, C indicate the opening and closing of the exhaust ports of a two-stroke engine cylinder with loop scavenging. The curve E shows the pressure drop in the cylinder and the curve F shows at P the exhaust pressure pulse in a succeeding cylinder connected to the same manifold. It will be seen that the exhaust manifold has been so designed that the pressure pulse has been utilised to increase the pressure in the cylinder at the time of the closing of the exhaust ports. This may be done by splitting the manifold into two or more parts to serve separate banks of cylinders or by lengthening the branches of the manifold which may be arranged by placing it over the engine. When the manifold is split, the cylinder utilised to increase the pressure may be a later cylinder in sequence than that firing immediately after the one in question. The invention is particularly applicable to an engine having loop scavenging as it will in that case stop the flow of air through the cylinder into the exhaust manifold, but it is also applicable to uniflow, poppet valve, opposed piston and sleeve valve engines. Specification 571,525 is referred to.

Title: Improved Manufacture of Tapestry' Pile Fabrics.
IPC: D03D39/00
Filed: 1919-05-07
Abstract: 126,643. Alva Carpet & Rug Co., (Assignees of Fromuth, A. G.). May 8, 1918, [Convention date]. Pile fabrics.-In tapestry pile fabrics, such as rugs and carpets, woven with parti-coloured pile warps and with patterns involving straight transverse lines of demarcation between different shades or colours, these transverse lines of demarcation are accurately formed by inserting a take-up rod 14 in the pile-forming shed along a line of change of shade or colour and alongside of a usual pile-wire 13, the rod 14 being of a diameter to contain in the loops formed thereon by the pile warps P the points of change between the shades 11, 12; the weaving is continued for some time, and then the pile warps P are cut in front of the rod 14 at the level of the pile loops, thus freeing the rod, which is removed. The wires 13 are then withdrawn by the usual automatic wire motion, their knives cutting the pile loops, and the projecting ends of the loops formed over the rod 14 are trimmed off by shears. The invention is shown applied to the weaving of a two-shot pile fabric, with wefts w, binder warps b, and stuffer warps S, but may be applied to three-shot or other fabrics.

Title: Improvements in photographic apparatus
IPC: G03B17/53
Filed: 1928-04-20
Abstract: 320,844. Bramwell, J. E. April 20, 1928. Automatic and coin-freed apparatus.-In a camera for taking a series of photographs, and having posing mirrors arranged round the lens, the exposures are controlled by the sitter by means of a remote control. The cabinet 1, Fig. 1, has mirrors 7, 8, - - each associated with indicators 10, 11 - - around the lens 9, and lamps 5 with a white opal glass screen 6 for illuminating the sitter. By means of a control 12, operated by the sitter, or a button 13, either an indicator within the closed part 2 of the cabinet is operated whereupon the exposure is effected by an operator within the part 2, or the exposure is effected directly. The insertion of a coin in the slot 14 may operate a master control of the shutter. The sensitized surface is carried by a slide adapted to move in its own plane in two directions at right angles. A spring contact on the slide closes in each exposure position circuits which either operate the shutter electromagnetically through a time-lag device and preferably also the appropriate indicator, or lights a small non-actinic lamp within the chamber 2 indicating that the slide is in position for a fresh exposure, which may be made through the remote controls 12 or 13. The slide is also provided with means for closing the shutter circuit manually in any position of the slide. In a modification, Fig. 5, wherein the presence of an operator within the cabinet is not essential, the insertion of a coin 30 in the slot 14 closes the circuit of a lamp 31 indicating that the mechanism is ready. The closing of the switch 32 by an operator or the switch 33 by the sitter then energizes an electromagnet 34, causing a lever 35 to move the commutator disc 37 one step. Thereupon an electric motor 38 is brought into circuit and drives a commutator disc 39 for a third of a revolution, so that firstly one of the indicator lamps 40 is illuminated, secondly the segment 43 shorts a pair of contacts 44 operating an electromagnet 45 for the shutter, thirdly a stop 46 on the disc 39 closes the circuit of an electromagnet 48 releasing a catch 49 and allowing the slide 50 to be moved forward one step by the weight 51, and fourthly the disc 39 engages one of the pegs 52 of the disc 37, breaking the circuit of the motor 38. The closing of the switches 32 or 33 a second time causes a repetition of the above operations. this time using the indicator lamp 41.

Abstract: 667,450. High frequency current and voltage measurements; current measurements with current transformers. STANDARD TELEPHONES & CABLES, Ltd. May 18, 1950, No. 12452/50. Class 37. A high frequency measuring arrangement comprises means for obtaining two D.C. voltages proportional respectively to the electric and magnetic fields set up at any given point by an energized conductor and means for measuring the sum of the said two D.C. voltages to obtain a measure of the energization of the conductor. In the embodiment shown a current transformer secondary encircles an energized aerial feeder 1 which forms the current transformer primary and the output voltage of the secondary is fed over a half-wave rectifier 5 and through a series resistor 10 to a D.C. meter 11 to produce on the latter a component of deflection proportional to the aerial current at the point of coupling of the secondary to the aerial feeder 1. The transformer secondary with the straight through primary or energized feeder 1 is surrounded by a metal electrostatic shield 13 which is connected to earth over a large capacitor 15 so that in effect a capacitative voltage divider is thus formed. The voltage developed across the capacitor 15 is.fed over a half-wave rectifier 16 and through a series resistance 17 to the meter 11 to produce in the latter a component of deflection proportional to the aerial voltage at the point of coupling of the secondary to the aerial feeder 1. The meter 11 may be calibrated to produce indications of aerial current and aerial voltage separately, with switches provided to cut-out separately the rectifiers 5 and 16. The rectifier 5 is connected across the secondary through a D.C. blocking capacitor 6 and a leakage path to earth for the latter is provided through a resistor 7. A de-coupling capacitor 12 is shunted across the meter 11 to short circuit interference A.C. components.
