Title: Improved height control system for a vehicle fluid suspension
IPC: B60G17/052
Filed: 1958-04-03
Abstract: 833,409. Adjusting body height. GENERAL MOTORS CORPORATION. April 3, 1958 [May 2, 1957], No. 10797/58. Class 108(2) In a height control system for a vehicle fluid suspension including a valve having inlet and outlet orifices 112, 114, Fig. 10, respectively for the supply and exhaust of compressed air to and from a spring under the control of an actuator responsive to vehicle clearance height, the sizes of the inlet and outlet orifices are in inverse relationship to the pressure differentials across the orifices. Front springs 16, Fig. 1, and lefthand rear spring 26 all have separate leveller valves 34. A righthand side rear spring 28 is connected to spring 26 by a conduit 82 having a restriction to prevent excessive air transfer when the vehicle rolls. A junction box 42, Figs. 1, 2, has air supply passages 54, 56, 50 which are respectively conected to the two front and the rear leveller valves. A restriction 48 limits the air supply to the front springs. Passages 68 receive exhaust air from the springs. A check-valve 78 prevents escape of air from a reservoir 38 back to a compressor 36. Check-valves in the leveller valves prevent escape of air from the springs. All the leveller valves are identical and are operated by levers 96, Fig. 6, which sense changes in vehicle clearance height. A lever 96 turns a yoke having ears 128, 132, which open inlet and outlet orifices 112, 114, Fig. 10, by lifting flapper, valves 116, 120 respectively. Lost motion is provided in the linkage by leaving spaces between ears 128, 132 and the portions of valves 116, 120 with which the ears co-operate.

Title: Load stabilizing means for modulating systems
IPC: G01S1/02
Filed: 1939-04-11
Abstract: 527,380. Modulating systems; directive wireless systems. INTERCONTINENTAL SERVICE CORPORATION. April 11, 1939, No. 10896. Convention date, April 4, 1938. [Class 40 (v)] In a modulating system, particularly for an overlapping-beam directional system in which a common carrier frequency modulated at different frequencies is supplied to separate aerials, crossmodulation in the carrier source is prevented by providing each aerial with a dummy load modulated in opposite sense, so that each aerial with its associated dummy load presents an approximately-constant impedance to the carrier source. The output of coil 5, coupled to the tank circuit 1, 4, is connected to two shielded transmission lines 10, 11, connected to supply current to an aerial 2 and a dummy load 13. A rotary condenser 14, 15, 18, connected through transmission lines 16, 17, impresses a characteristic modulation upon the carrier radiated by 2, and modulates the energy supplied to resistance 13 in opposite sense, so that the sum of the radiated energy and the energy dissipated in resistance 13 is approximately constant over the modulation cycle. The short-circuited lines 20, 21 are for the purpose of tuning. A similar aerial 3 and load 30 are fed from the circuit 1, 4, by coupling coil 6, and the modulation is performed by the rotary condenser 35, 36, 37, which is arranged to produce a different characteristic modulation.

Title: Improvements in grease guns and methods of filling
IPC: F16N37/02
Filed: 1926-04-26
Abstract: 274,580. Punch, J. F., and Flinn, H. V. April 26, 1926. Piston apparatus for discharging receptacles.- A cartridge for filling a grease gun has a packing ring B at the lower end so that when the cartridge is drawn out of the gun by the handle D, the atmospheric pressure on the piston C forces the grease into the gun. In the form shown in Fig. 5 a gland M is formed on the outer end of the gun with the same effect. The packing ring on the cartridge may consist of a ring of rubber, Fig. 2, with a number of slits on the periphery, so that when it is forced on to the cartridge, it assumes the form shown in Fig. 3. In another form, the inner end of the cartridge engages, as by a screw thread, a packing member arranged at the inner end of the gun barrel, so that when the cartridge has been withdrawn it may be extracted therefrom and the packing returned to its inner position. In another form, a ring, Fig. 6 (not shown), is mounted between the flanged end of the gun and a flange sleeve screwed into the gun. In another form, Fig. 7 (not shown), a convex plate on the end of the cartridge is bent by engagement with the inner end of the gun and forces a packing ring into contact with the gun barrel.

Title: Improvements in and connected with the locking devices of railway signal and point levers
IPC: B61L19/16
Filed: 1921-04-14
Abstract: 181,186. Dibbin, H. A. April 14, 1921. Hand-levers and hand gearing.-A master lever, which, through interlocking gear, controls the ordinary original and points levers, is automatically locked in each extreme position by electrically-controlled catches, which are released to permit movement of the master lever either by a train passing over a ramp or by the closure of a circuit at the cabin ahead. Fig. 1 shows in elevation one catch apparatus partly in section, and Fig. 2 shows a plan view partly in section. A centrally-pivoted catch plate 5 provided with a projection 6 prevents the movement of the master lever 1 except when a block 8 carried by a flexible blade or lever 9 is raised as current is passed through an electromagnet 11 carried on the blade 9 so that the magnet 11 is attracted to its armature. In another form of catch used for the opposite end of the movement of the master lever, a similarly-shaped catch with a projection 6 is controlled by a blade 9 and block 8 in which the armature of the magnet is carried on the blade 9. The master lever is normally locked in the position shown, and the main-line home signals are then correspondingly locked by the interlocking from the master lever, but the subsidiary point and signal levers are free to permit shunting &c. When the forward cabin closes a circuit to unlock the master lever by freeing the catch 5, the master lever is moved over into the opposite extreme position, and is there automatically locked. This frees the main-line home' signal to permit departure of a train, but locks the subsidiary point and signal levers against actuation. The master lever is subsequently unlocked as the train passes over a track ramp to close a circuit to the locking catch. The energization of the catch magnets is maintained over periods of train transit by any form of self-locking switch in conjunction with the usual block instruments in the cabins.

Title: Improvements in or relating to winnowing machines
Inventor: MCLEAN KENNETH
IPC: B07B4/08
Filed: 1968-03-06
Abstract: 1,263,264. Pneumatic separation. CO-OPERATIVE WHOLESALE SOCIETY Ltd. 6 March, 1969 [6 March, 1968], No. 10967/68. Heading B2H. In a winnowing machine, a downwardly inclined, material-supporting apertured screen 9 extends across a vertical duct 8 from an inlet for untreated raw material, e.g. threshed vines, to an outlet for the desired product, e.g. peas, and a fan 3 forces air along the duct 8 and through the screen 9 so that waste material is carried from the screen by the air stream to the upper end of the duct, over the horizontal edge 17a of a vertically adjustable plate 17 and into a downwardly extending conduit 14. A vertically adjustable member 4 controls the amount of air inducted into the fan inlet 2. The fan delivers the air through flow-straightening vanes 7 mounted in a convergent duct 6 having a circular cross-section at its lower end and a square cross-section at its upper end. The duct 8 is also of square cross-section. The screen 9 is constituted by means of spaced rods and observation of, and access to, the screen is by means of a door 27 having a transparent panel. A feed chute 10 and discharge chute 12 are connected to the inlet and outlet. The size of the inlet opening may be adjusted by a flap plate pivotable or vertically slidable towards and away from the bottom of the chute. The plate 17 is vertically adjustable by means of a screw 20 which may be actuated by an external wheel 23. An aperture in the wall of the conduit 14 is normally covered by hinged wire mesh doors 26 through which most of the air entering the conduit escapes to atmosphere. Reference has been directed by the Comptroller to Specification 1,075,469.

Title: Improvements in or relating to plug valves for controlling fluid flow
IPC: F16K5/02
Filed: 1960-03-29
Abstract: 910,536. Valves. DURIRON CO. Inc. March 29, 1960 [July 24, 1959], No. 11040/60. Class 135. A rotary conical plug valve for controlling corrosive fluids, comprises a valve body 20 having inlet and outlet ports 22, 23, a plug 40 mounted in a liner 30, the plug having a port 41 adapted to align with the inlet and outlet ports in the open position of the valve, the plug, liner and the body being so constructed and arranged that during the rotational movement of the plug from its open to the closed position the outlet port is closed completely while the interior of the plug port is still in communication with the inlet port of the body. The liner, which may be of polytetrafluroethylene, is clamped in the body by a plate 35 and, together with the plug 40, is sealed by a diaphragm 37. In order to prevent the edge of the liner around the upstream side of the plug port 41 from being lifted away from the body due to the high pressure differential when the plug is only partially open, the upstream end of the port 41 is enlarged at a point 67, thereby ensuring that the maximum pressure drop occurs at the downstream end of the port 41 so maintaining the liner in contact with the body. If desired, the opposite end of the port 41 may be similarly enlarged in order that the fluid may flow in either direction. In the embodiment shown in Figs. 7, 9, the port 121 is tapered, its ends aligning in the open position with similarly shaped inlet and outlet ports 102, 103; in this construction, the liner is provided with ribs 118 engaging corresponding recesses in the body in order to prevent relative rotation. The plug may be rotated through a single detachable handle or through a hand wheel-and-gear drive.

Title: Compressor pressure governor
Inventor: SCHULTZ FORREST O E
IPC: G05D16/02
Filed: 1971-04-23
Abstract: 1291025 Valves MIDLAND-ROSS CORP 23 April 1971 [8 May 1970] 11135/71 Heading F2V A governor for controlling pressure, intended to be used in combination with a reservoir 16, a compressor 12, and an unloader valve 14 for releasing pressure, comprises a housing having an inlet 96 for sensing the reservoir pressure, an outlet 100 communicating pressurized fluid via line 24 to the unloader valve for "unloading", and a vent 78 communicating to atmosphere relieving the line 24 for "pumping". Two valve members 36, 38 are contained in the housing, the valve 36 controlling communication between the inlet 96 and a chamber 82 formed by the housing and the valve 38, the latter controlling communication between the outlet 100 and the vent 78. A passage 46 provides for limited communication between the chamber 82 and the outlet 100 when the valve members are in their upper position (Fig. 1). The passage becomes less restricted when the valve 38 is in its lower position (Figs. 3 and 4, not shown). If the reservoir 16 is below the required pressure, an adjustable loading set 65, 66 urges valve 38 to its upper position (Fig. 1) in which the line 24 is vented and the compressor pumps the reservoir. If the reservoir is at the required pressure, the fluid acts firstly on diaphragm 58 affixed to valve 36 to lift it off seat 86 and then acts on the top of valve 38 in chamber 82 to compress the loading. The valve 38 seats on seat 92 to close the outlet 100 to vent 78; pressurized fluid flows through the passage 46 to switch the unloader valve (Fig. 2, not shown). Initially both valves 36, 38 are depressed but the pressure between chambers 82 and 84 is equalized and the valve 36 returns to its upper position (Fig. 3, not shown). During the unloading mode differential pressure can flex slightly the diaphragm 58 between chambers 84 and 90 or depress slightly the valve 36 maintaining equal pressures in the two chambers.

Filed: 1933-04-13
Abstract: 411,648. Moulding ridge tiles &c. WALDBOTT, B. C., Tolcsva, and GROSSMAN, J., Haromhuta, both in Hungary. April 13, 1933, No. 11168. [Class 87 (ii).] In a method of moulding ridge and like tiles by pressure from dry or semi-dry powdered material, the angle of the die is fixed at or less than the angle of repose of the material a so that the powder will remain in the position shown in Fig. 1 in which a constant thickness is presented to the pressing-die in the direction of pressure, and will not assume a position such as shown in Fig. 2. In making a ridge tile, ground clay is passed through a sieve and moistened up to a content of 8 or 15 per cent. The moistened powder is dropped into the die by a travelling distributing carriage with delivery slats in the base, and thereafter is levelled by a spreading member, which removes any excess and equalizes the thickness. Pressure is then applied and the pressed tile subsequently dried and burnt. In some cases the dies are covered initially with glazing or slip and may be made of a number of superposed layers of different materials.

Title: Improvements relating to cigarette lighting and dispensing machines
IPC: G07F11/72
Filed: 1929-04-11
Abstract: 310,324. Cent-a-Puff, Inc. April 23, 1928, [Convention date]. Igniters combined with cigarette - delivery machines; lighting cigarettes by electric devices. -In a coin-freed machine for delivering cigarettes in a lighted condition, a coin 70, Fig. 1, inserted in a shoot 55 transmits the thrust of a knob 57 to a lever 59 which actuates a rod 60 to close the switch 33 of an electric motor 1. The motor, through belt gearing, drives a suction pump, and a worm 3 engaging a wheel 7 carrying a cam 8. A pin 74 on the face of the cam moves a lever 28 having a depending rod 33<a> to rock a plate 34 which carries a pawl 39 engaging a ratchet wheel 37. The wheel 37, by toothed gearing, rotates a grooved cylinder 26, Fig. 4, through the space of one groove at a time to carry a cigarette, lighted at the position 72, over the edge 78 of a guard plate 79, the cigarette then dropping down an incline 80 to a delivery aperture 81. The next groove, with a cigarette therein, is brought to the lighting position and a roller 37<a> rotated in the same direction as and at a greater speed than the cylinder 26 allows only one cigarette at a time to enter an empty groove of the cylinder. Just before the pin 74 escapes from a shoulder 75 on the lever 28, a link 31 opens the switch 33 to stop the motor, the momentum of which carries the pin 74 along a surface 82. When the pin leaves the surface 82, a spring 45 restores the lever 28 to its initial position. Before the pin 74 actuates the lever 28, the edge of the cam S rocks a lever 10 connected by link 14 to a hooked rod 16 which causes a rod 19 to slide axially against the action of a surrounding coiled spring. The rod carries a hollow pusher 23, Fig. 5, the mouth 27 of which engages and presses a cigarette at the position 72 against an electric heating element 69. The pusher 23 is connected to the suction pump by a flexible connection 65 and hollow tube 64, so that the pump draws air through the cigarette and lights it as long as the lever 10 engages the plain portion of the cam 8. The Specification as open to inspection under Sect. 91 (3) (a) comprised the subject-matter of Specification 336,661. This subject-matter does not appear in the Specification as accepted.
