Title: Improvements in fluid pressure brakes
IPC: B60T13/24
Filed: 1928-05-21
Abstract: 290,980. Bonnebeau, R., and Bonnebeau, G. May 21, 1927, [Convention date]. Fluid-pressure.- Relates to fluid-pressure brakes more particularly for motor vehicles in which the brake system forms an integral port of the distribution system, the masking and unmasking of the ports of which is effected by an axially movable valve connected to the brake pedal. The valve 14, Fig. 1, forms three chambers 18, 16, 28 within the brake-piston 12. Chamber 16 communicates with the interior 25 of the brake cylinder by a passage 27, with the chamber 18 by a passage 17 and in the brake release position with the atmosphere through a passage 20. When the valve 14 is moved to the right by the brake pedal connections 1, 2 it closes the atmospheric passage 20 and opens the chamber 16 to a passage! 22 which communicates with an annular chamber 23 open to a source of suction through a passage 24. Chambers 12, 18, 25 are thereupon evacuated and the piston 12 moves to the right to apply the brakes by connections 3, 4 and also a reaction effect proportional to the braking pressure is felt by the operator in view of the vacuum existing in the chamber 18, and the atmospheric pressure communicated to the chamber 28 by means of a passage 19. If the valve is now held stationary the piston 12 will still continue to move until the port 22 is closed and a desired degree of vacuum is maintained. A ring 31 on the valve stem allows the operator to act directly on the piston and the brakes. In a modification a supplemental piston 61, Fig. 2, assists the action of the piston 12 and is connected thereto by a tube 19 and a collar 63 and is contained in a part of the same cylinder divided off by a partition 60 through which the tube 19 passes. Atmospheric pressure is maintained on one side of the piston 61 by ports 65 and a gauze covered funnel 67 and pressure variations on the other side of the piston correspond to those acting on the piston 12, being effected through the tube 19 and ports 17<1> communicating with the chamber 16. The valve 14 slides over a part 19<1> of the tube 19. Atmospheric pressure is maintained in the chamber 28 by an extension of the passage 20 and a port 19". The pistons 12, 61 may be contained in separate cylinders. The apparatus may be arranged to work with compressed air. Arrangements for lubricating the apparatus comprise a bath 77, Fig. 3, of oil contained in a part 75 of the piston which projects as far as the bearing parts 76 of the piston. Grooves 78 connect the bath with circumferential grooves 79 in which are fitted lubricating wicks. Radial grooves 81 ensure lubrication of the valve 14, Fig. 1. An oil reservoir, pressure in which is established by a spring-pressed plate, supplies the bath.

Title: Improvements in and relating to liquid meters
IPC: G01F3/18
Filed: 1948-06-04
Abstract: 663,750. Liquid meters. BECK & CO., Ltd., and SOAR, H. G. June 7, 1949 [June 4, 1948 ; May 5, 1949], Nos. 15152/48 and 12090/49. Class 69 (ii). The invention relates to liquid meters having pistons which reciprocate under the action of the supply or feed pressure and are rotated as a consequence of such axial movement, the rotation serving to make cyclic changes in the circuits from the source of supply to the delivery point. Each piston reciprocates in a cylinder closed at each end and has in it passages, chambers or bores leading from opposite ends of the piston and terminating at ports in the peripheral surface of the piston. In such meters a transverse passage is provided in each piston. It serves as a balancing passage and in one arrangement transfers liquid from a source of supply to one of the ports in the piston. Fig. 4a shows part of a liquid meter having two pistons 114 which are each connected by means of a known arrangement comprising a pinion co-operating with a crank pin to an indicating mechanism. Reciprocation of the pistons under the influence of liquid pressure causes the pinions to be rotated and the rotation of the pinions imparts a rotary oscillatory motion to the pistons. Liquid under pressure is supplied through a passage 118 and is delivered through a passage 124. Oscillation of the pistons causes bores 146, 148 therein alternately to direct liquid to opposite ends of the cylinders, the pressure liquid passing to the bore 148 through a transfer passage 165 in the piston when the piston has been rotated in a clockwise direction into a position in which this bore communicates with a space 156. The supply pressure acts through the passage 165 upon the underside of the piston and balances the effect of the same pressure acting above the piston. A balancing passage 166 is provided in the piston which at all times communicates with the delivery side of the meter 124, and transmits the delivery pressure to a space 154 where it balances the same pressure acting on the piston at the delivery side. The spaces 154, 156 are formed by a ported liner (not shown). In a modification each piston has three bores for directing the liquid to and away from the ends of the cylinders. In this case two balancing passages are provided but neither acts as a transfer passage for supplying liquid to the cylinder ends. The passage 165 could be replaced by several passages and the passage 166 could be omitted. The bores need not be cylindrical nor need the balancing and transfer passages be cylindrical. Specification 663,762 is referred to. According to the first Provisional Specification the pistons have four bores only three of which play an active part in the operation of the meter. The fourth bore is provided so that the piston is dynamically balanced.

A semi-conductor diode rectifier, or other device, comprises a semi-conductor wafer 4 surrounded by an insulating spacer 3 and bonded to central portions of double-dished electrodes 1, 2 which are themselves bonded to spacer 3. The electrodes are of swaged sheet copper and are coated with gold to facilitate brazing, the spacer being of ceramic material with metalplated end surfaces. The brazing or soldering material is preferably a lead alloy. A pair of grooves 7, 8 are formed in one end of spacer 3 whereby the enclosure may be evacuated or filled with a suitable gas (e.g. nitrogen), the grooves being sealed using a heat-polymerizable substance. Alternatively grooves or orifices may be formed in either or both of the electrodes. The components are stacked on a stainless steel support, the parts to be bonded first being coated with solder, and are heated to about 350‹ C. in a suitable atmosphere (in vacuo or inert gas). Instead of solder coatings, discs of solder punched from a sheet may be used. Several diodes may be connected in series by stacking and clamping them. Suitable dimensions for the various parts are given in the Specification. The two electrodes may be of different shapes to distinguish their polarities.

Abstract: 757,496. Jet propulsion plant. SOC NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. June 3, 1953 [June 5, 1952], No. 15362/53. Class 110(3) An air intake of a jet propulsion engine in which the flow of gas or air is controlled by a sheet-like jet or jets projecting into the intake has the jet or jets formed by a nozzle or nozzles inclined in the direction opposite to the flow to be controlled with the wall or walls of the nozzle or nozzles downstream of the flow to be controlled forming a sharp edge or edges with the adjacent wall of the intake. In the case of a ram jet, the intake is controlled by nozzles inclined forwardly and in the case of a pulse jet the back flow of gas from the combustion chamber is controlled by nozzles inclined rearwardly. In the ram jet shown, Fig. 1, the fairing 1 encloses a faired body 2 to form a slightly convergent - divergent intake passage. Slots 4 and 5, arranged in the fairing 1 and body 2, are supplied with compressed air from a compressor 3a driven by a gas turbine 3b. The flow of compressed air is controlled by a valve 7. In a modification, the air supplied to the slots 4 is drawn from a forwardly facing duct formed on the axis of the body 2. In a further modification, slots are formed in the fairing 1 and when compressed air is supplied to the slots 4 some of the air entering the unit is forced through the slots in the fairing 1 to the exterior of the unit. In the arrangement shown in Fig. 4, the air inlet 16 of a pulse jet unit comprises a faired body 18 having a slot 17 or a slot 20 or both to which gas under pressure is supplied by pipes 19 and 21. The pipes 19 and 21 may be connected to the combustion chamber 15, to a cylinder of compressed air or to a steam generator which may be a cooling jacket around the combustion chamber 15. The gas or steam enters the intake 16 at an angle of about 20 degrees to its axis and prevents the discharge of the gases from the combustion chamber 15 back through the intake. Specification 745,630 is referred to.
