Title: Hydraulic brake system for motor vehicle - eliminates leakages and does not use fluid storage tank
IPC: F16D65/22
Filed: 1973-05-21
Abstract: The hydraulic brake system is simplified by not using a brake fluid storage tank. The pressurised fluid within the brake actuating system is completely enclosed and sealed. Actuating pressure for the brakes is generated by applying mechanical force on the main cylinder. The main cylinder is a flexible bellows assembly with the actuating plug 11 which is fixed on one end of this bellows arrangement. The flexible bellows is compressed and its volume is reduced for generating hydraulic pressure. The fixed end 35 of the flexible bellows assembly is held on the vehicle frame. The pressure in the hydraulic system is transmitted through connections and pipes to the brake actuating cylinders which are also flexible bellows. These bellows expand under applied pressure and actuate the brake system.

Abstract: System for wireless transmission of multiple information signals making use of digital time division circuits between a base station 11 and a number of subscriber stations 10. The subscriber stations can be fixed or mobile. The number of time division circuits is determined by the transmission quality of the signals. The base station 11 is connected to an external analog and/or digital information network 12. The information signals are voice, data, facsimile, video, computer or other instrumentation signals. The modulation level of the signals and the system's power are adjusted in dependence on the signal error detection in the system. The system assures spatial differentiation by making use of several antennas at an interval from each other, so that relatively strong signal reception is achieved despite fading. The base station 11 operates over several radio frequency channels, and the operation of each channel pair occurs by a combination of a transmission channel circuit for processing of a given number of information signals arriving simultaneously over telephone lines, which are sent out simultaneously over a given radio frequency channel to various subscriber stations 10, and a receiving channel circuit for processing of signals which are received simultaneously from various subscriber stations via a given radio frequency channel, in order to form information signals for transmission over the telephone lines. <IMAGE>

Abstract: The injector has an atomiser 10, closed at the front and having one or more atomising nozzles 11 in its side wall. The injection of atomised fuel is controlled by a slide 13, axially displaceable in the injector, which is spring- loaded towards its closing position in which it blocks the injection nozzles, and is affected towards its opening position where it uncovers the injection nozzles by the pressure in the supplied fuel. The inner cavity 34 of the slide which forms part of the flow passage of the fuel towards the injection nozzles, ends with a converging portion 34b which in the opening position is in connection with the injection nozzles through a generally V-shaped cut-out 36 in the surface of the slide. The gradual acceleration of the fuel flow in the end portion 34b of the cavity and its deflection outwardly against the inner side of the atomiser entails an improved atomising and thereby an improved fuel economy. <IMAGE>

Abstract: A burner with an integrated electrical high-voltage igniter and a flame monitor for partly oxidizing gaseous fuels in reactors that are either pressurized or not. A fuel-gas channel communicates with a confusor which opens into an annual fuel-gas nozzle. The fuel-gas channel, furthermore, is surrounded by an annular oxygen channel. Water channels border the confusor and the annular fuel-gas nozzle. The annular fuel-gas nozzle, moreover, has the confusor, and annular nozzle with a reaction zone end, and a diffusor. This diffusor merges into the oxygen channel at an axially parallel radius of curvature. A high-voltage ignition cable extends through the fuel-gas channel and terminates in a metal electrode which is positioned so as to form a spark gap in a space between the tip of the electrode and a metal wall of the burner. In this space within the spark gap, the fuel gas and oxygen mixture is turbulent, whereby the fuel-gas channel provides a reliable and certain ignition of the fuel gas and oxygen mixture independent of gas pressure in that space. The radius of curvature is located at an exit end of the diffusor and extends into the oxygen channel for separation of gas from walls of the diffusor to produce a vacuum in the spark gap space for suctioning the oxygen from the oxygen channel.

Abstract: A transport system consists of a vehicle and a load accommodation space which can be lowered or lifted for loading or unloading purposes respectively, and which can be shifted upon the vehicle. The load accommodation space may be a conventional platform or stage (9) or, for instance, an enclosed body (1) like a container. In the bottom of the load accommodation space a cut-out (10) has been provided which enables the load accommodation space to be horizontally displaced to come into register with the load. The load has been placed on a load carrier (14) with projecting sides or equivalent supports that are clear of the ground. The sides of the load carrier (14) remain to be borne by the margins of the aperture (10) in the stage (9) when the stage is raised aloft. The load carriers (14) will then constitute the bottom of the load accommodation space. It is possible on the lower margin of the stage (9) or equivalent constituting the load accommodation space to mount small rollers (13), whereby the horizontal shifting of the stage is facilitated.
