Title: Improved illuminated bollard for street traffic
IPC: E01F9/615
Filed: 1933-04-27
Abstract: 411,656. Road-traffic warning lamps. MACFARLANE, W., Saracen Foundry, Possilpark, Glasgow. April 27, 1933, No. 12247. [Class 75 (iv).] In a road-traffic warning lamp adapted to produce a light-and-dark effect both by daylight and at night, a lantern adapted to project light downwardly overhangs a post or support having on one or more sides a vertical column of outwardly and downwardly inclined light reflecting surfaces alternating with inwardly receding surfaces.

Patent GB-928342-A (GB)
Title: Relating to a universal fluid pressure balance or deadweight pressure gauge tester
IPC: G01L27/00
Filed: 1960-04-06
Abstract: 928,342. Testing pressure gauges. W. C. 'T. HART & ZN. INSTRUMENTEN-EN APPARATEN-FABRIEK N.V. April 6, 1960 [Nov. 27, 1959], No. 12301/60. Class 106 (2). A universal pressure balance or dead weight pressure gauge tester comprises a set of weights carried by a support borne by a plunger that is movable in a cylinder connected to a source of high-pressure fluid, means for imparting relative movement of the cylinder and plunger about the axis of the latter and means for raising the weights individually from the support, at least three of the weights forming a geometric series. Fluid under pressure is supplied from the system 23 through a conduit 22 into a cylinder 4 in which slides a plunger 5 carrying a weight support 7. The weight support has a number of flanges 9 on which the weights may be supported, e.g. as illustrated by the weight 13, and is rotated by an electric motor 20 to reduce errors due to friction. Three vertical supports 30 are mounted on the base-plate 2 of the machine and carry rollers 29 which co-operate with wedge shaped surfaces 28, Fig. 2, on a number of rings 27 (one for each weight). Upon the rings are mounted rollers 27A and handles 31. To raise any particular weight, the corresponding ring is turned about the vertical axis and the rollers 29 engaging the wedge-shaped surfaces 28 raise the ring and this in turn causes the rollers 27A to raise the required weight. The weight 11 is shown raised and out of action in the drawing. The heaviest weights 15, 16, 17 which are all of the same size can only be raised in that order, since the weights 15, 16 rest directly on the bottom weight 17. This results in a reduction in the height of the apparatus. The fluidpressure supply system consists of a gear pump 42 pumping fluid from a reservoir 41 through a non-return valve 56 into a cylinder 52. The pump also supplies fluid through a pressure regulator 55 to the low-pressure side 47 of a differential piston 46. When the pressure on this surface is sufficiently high the piston 46 is driven to the right, thus forcing fluid from the cylinder 52 through a non-return valve 53 and into the conduit 22 leading to the weight chamber, and also into a conduit 61 leading to the pressure gauges being tested. After this operation, the low-pressure side 47 is exhausted by manual operation of a three-way valve 49 and a spring 46A returns the piston 46 to the left. The valve 49 is then turned clockwise and the cycle repeated. To prevent the pressure gauges from being subjected to a change in pressure every cycle and so suffering from hysteresis, a needle valve 65 operated by a piston 66 can be closed by connecting the righthand side of the piston 66 to the pump and the other side to the reservoir 41. Manual operation of a further valve 60 makes this possible. To ensure firm closing of the needle valve 65, the pressure supplied by the pump 42 to the piston 66 is considerably higher than the pressure acting through the regulator 55 on the differential piston 46.

Title: Improvements in or relating to the supply of air to the cylinders of two-stroke internal combustion engines
IPC: F02B25/00
Filed: 1934-04-24
Abstract: 436,969. Two-stroke-cycle engines; starting. PETTERS, Ltd., and PETTER, P. W., Westland Works, Yeovil, Somerset. April 24, 1934, Nos. 12369 and 34525. [Classes 7 (ii) and 7 (v)] In engines in which the suction effect created by the exhaust gases is relied on to induce scavenging and charging air into the cylinder, the absence or weakness of such suction at starting or low speeds is compensated for by air or mixture compressed in the crank case. The transfer from the crank case may be controlled by a screw-plug valve D<2> operated manually, or by a rotatable sleeve-valve H operated manually, or automatically by an engine-driven governor. The sleeve-valve has two sets of ports. One set affords a through passage from the crank case to the cylinder for air drawn into the crank case past a flap-valve. The other set opens a passage from the crank case to atmosphere when the first set is closed against the cylinder. In a modification, the crank case may be provided with a breather-valve N which during normal running is kept open by an engine-driven centrifugal governor o<1> At starting or during slow running, the governor is inoperative, and the valve N acts as a non- return valve admitting air which is compressed in the crank case and afterwards transferred to the cylinder.
