Title: Improvements relating to pressure registering apparatus
IPC: G01L19/00
Filed: 1935-05-16
Abstract: 454,978. Regulating flow of fluids; gauges. ARCUS, C. R., 152, Browning Road, East Ham, London. May 16, 1935, No. 14354. [Class 135] [See also Group XIX] An apparatus for protecting a pressure gauge subject to excessive fluctuations of pressure as when used with oil-fuel pumps of Diesel engines, comprises a non-return trap-valve F admitting the oil from the pump at B to the gauge at C, the valve having a piston portion with fine throttling groove f. An air-cushion D, with sump K for sediment, is provided, and a fine groove h on a valve H permits gradual release of the oil from the gauge to a drain pipe L. If the chamber D becomes depleted of air, the valve H is withdrawn from the passage J by a handle N, allowing the chamber D to discharge oil, and to recharge with air through a hole M. If desired, a spring may be fitted above the valve F.

Title: Improvements in weights for use in fishing
IPC: A01K95/00
Filed: 1950-06-08
Abstract: 683,430. Sounding-apparatus. WILLIS, A. B., May 7, 1951 [June 8, 1950], No. 14355/50. Class 97 (ii). [Also in Group VI] A fishing sinker 1 which can be used to find the depth of water is formed with a bore in which a stem 3 carrying an open eye 2 for the fishing line is slidably mounted and a spring 7 acting between a shoulder 6 in the bore and a push knob 5 on the end of the stem draws the eye towards the sinker, thereby closing the opening in the eye. The top of the sinker may be cup-shaped, as shown, to correspond to the shape of the eye, or it may have a slot into which the open part of the eye is drawn, the slot being of such depth that when the eye is drawn thereinto the line is either free to run through the eye or is clipped between the eye and the surface of the sinker. The sinker may be shaped as a frustum of a cone, ovoid or plummet-shaped, or as a thick flat disc with the bore transverse to the axis. In use the weight is attached to the line above a split shot or is clipped to the fishing hook and the length of line run out when the weight touches the bottom determines the depth.

Title: Improvements in electric primary cells
IPC: H01M12/06
Filed: 1934-05-12
Abstract: 437,821. Batteries. GORDON, C. J., 77, Tufnell Park Road, London. May 12, 1934, No. 14407. [Class 53] A primary cell or battery contains a supply of water which is out of contact with the electrolyte which consists of a deliquescent material held in a fibrous substance between the electrodes. Under normal atmospheric conditions the vapour from the water provides sufficient moisture for the electrolyte. Fig. 2 shows a cell provided with a chamber 37 in the form of a hollow plug containing a pad 26 in which water is absorbed. Water vapour passes to the electrolyte which may consist of powdered calcium chloride held in a layer of wood wool between a magnesium electrode 28 and an outer electrode 32 consisting of copper gauze to which carbon powder is applied. A certain amount of the dry electrolyte may be mixed with the carbon powder. Holes 35 are provided in the casing to allow access of air for depolarization. Fig. 1 shows a battery consisting of a number of cells 4 to which water vapour is supplied from a common reservoir at the bottom of the casing. The water may be absorbed in a layer of absorbent material 26 such as wood wool or silica gel. In the latter case the gel may be packed round the lower part of the battery elements 4, 32. The use of water vapour to moisten the electrolyte may also be used in batteries as described in Specification 426,654. Specifications 423,301 and 423,353 also are referred to.

Title: Improvements in or relating to direction finding radio receiving systems
IPC: H03G3/22
Filed: 1937-05-25
Abstract: 496,217. Directive wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and APPLETON, W. A. May 25, 1937, No. 14528. [Class 40 (v)] Relates to means for applying automatic volume control to a direction-finding set so that the signal strength fed to the indicator is made independent of the prevailing fieldstrength, though the ordinary directional response to differences of orientation is maintained. According to the invention the pickup from a frame aerial 1 is fed to two valves 2, 3, and gives directional effects in a pair of headphones or other suitable indicator. Simultaneously the pick-up from a non-directional aerial 4 is amplified by a control valve 5 feeding a rectitier 9, which, in series with a resistance 10, is included in the common grid circuit of the valves 2, 3. This provides a control bias which in regions of high fieldstrength reduces the sensitivity of the valves 2, 3, and vice versa. The aerial 4 may be the usual vertical aerial used for " sense " determination, Fig. 2 (not shown).

Abstract: 1498955 Machinery safety devices GLOVER WEBB & LIVERSIDGE Ltd 2 April 1975 [2 April 1974] 14641/74 Heading F2J [Also in Division B8] In a refuse vehicle housing a packing device transferring refuse from a hopper to a main body a guard is provided to obstruct access to the hopper opening when the packing device is moving adjacent thereto. A guard barrier frame pivoted to the hopper opening is movable from the inoperative position to a guarding position by a cam lever follower 26 acting through an elbow member 30. A cam 20 is secured to the actuating crank 48 of the packing device by members 22, 24 so that the cam 20 engages the follower 26 to force it down to raise the guard during that part of the cycle when the packing device is passing the hopper opening to shield a user from contact with the packing device. If the packing device is reversed the two parts of the followers 26 pivot at 34 as allowed by stops 36, 38 so that the guard 14 is not moved. When the packer plate does not move in a continuous cycle movement of the barrier to its operative position may iniate a cycle.

Title: Improvements in and relating to carburetters for internal combustion engines
IPC: F02M1/00
Filed: 1936-05-25
Abstract: 475,426. Spray carburetters. GENNERMANN, A. May 25, 1936, No. 14695. Convention date, May 25, 1935. [Class 7 (iii)] A floatless carburetter comprises several sets of jets, a common delivery nozzle, control means for associating any selected set of jets with the delivery nozzle, and distribution means common to all the sets for interposing a particular type of jet such as a pilot, intermediate or main jet, in the fuel duct between the fuel supply and the delivery nozzle, the carburetter thus being usable with different kinds of fuel. Interconnected air and mixture valves control a mixing chamber 1 into which projects an axle 15 carrying a fuel nozzle 25 upon it, the axle being rocked by movement of the air valve to which it is connected by arms 54, 55. The axle 15 projects from a casing 47 housing a disc 12 integral with the axle and formed with fuel passages 35 leading to an axial bore 27 in communication with the nozzle 25. The other ends of the passages 35 terminate against a fixed disc 13 in which are formed the pilot, intermediate and main jets, rotation of the axle 12 thus adjusting simultaneously the angle at which the nozzle 25 is set in the mixing chamber and which of the pilot, intermediate or main jet is in use. The disc 13 abuts a further disc 16 provided with an arm connected to the piston of a suction motor 8. At starting, a passage in the axle 15 puts a pipe 7, leading from the suction motor 8; into communication with the mixing chamber and the motor turns the disc 16 to open a passage for the fuel to the pilot jet, the piston being checked by a resilient stop which may be over-run, if suction is intense, to cut off the fuel supply completely. The piston may be actuated manually. On opening the throttle by rotating the disc 12, a further passage in that disc admits air to the suction motor and the disc 16 is turned to the normal running position. The disc 16 abuts an apertured flange 22 in the casing 47, the remote face of the flange abutting a manually rotatable control disc 40 in connection with supplies of different fuels, the position of the disc for each supply being accurately maintained by a spring-pressed ball engaging a recess in the disc. The fuel nozzle 25, Fig. 17, projects into a Venturi 62 having a cut-away portion to receive the nozzle when it is turned into position at which it is fed by the pilot jet, the nozzle then being directly opposite to a suction controlled air inlet 6.
