Abstract: A cartridge (7) for removing contaminants from a liquid comprises (a) a central inlet or outlet, (b) a circumferential outlet or inlet for radial flow through the cartridge and (c) a resilient, helically coiled plate (8) permeable to liquid. One edge of the plate is secured at or near the central inlet or outlet, the other edge is secured at or near the circumferential outlet or inlet and means is provided for tensioning the plate. 
     The cartridge may be used in a filter.  
It may be modified by adding a fibrous layer to the coiled plate. This renders it suitable for use as a coalescer.

Abstract: A motion controller is described that provides accurate control of DC servo motors. The motion controller provides complete control of motor speed, direction, acceleration, deceleration and position as programmed by the user. The user defines the unique motions by generating chords. Groups of the chords are combined to form motion profiles. The profiles are interrelated via a high-level language to form functional areas that combine to generate an overall control. Adjustable gain, conditional logic, programmable controller intervention, dwells, and output information are all utilized to facilitate program generation. An interconnectable programmable panel allows user access to the controller. The motion controller further has a manual operation mode.

Abstract: An anti-theft device for an automotive vehicle such as a car or truck having fluid pressure-operated brakes. The device includes a lockable member that, when activated while the brakes have been applied by the driver, inhibits any substantial change in the then existing fluid pressure condition in the brake fluid pressure system of the vehicle. The brakes thus remain locked, preventing normal movement of the vehicle, even if the brake pedal is subsequently released and the engine is running. The device can also include an additional lockable member for immobilizing the brake pedal to prevent its being depressed. Optionally, the device can also include one or more electrical switches which are operated, when either lockable member is activated, to ground out the distributor and or open the ignition circuit at a point away from the ignition lock terminals, thereby to prevent starting of the engine. Preferably a special key is provided for releasing the lockable member, and special screws, e.g. screws with non-conventional heads, can be used to assemble the device as well as to mount the operator-accessible parts of the device in the vehicle so as to make removal or disassembly of the device more difficult.

Abstract: To increase the packing density of shift registers of integrated design, according to the invention bipolar memory cells are used as switching stages. For each bit position, a pair of memory cells is required, controlled by clock pulses of a first and second clock phase. Since, in the case of normal memory cells used in random-access memories, the same terminal points are used as input and as output, additional, directionally dependent transmission elements are required, which prevent reactions of the potentials at the outputs affecting the switching state of the memory cell respectively preceding in the direction of transmission. <IMAGE>

Abstract: In a method of and apparatus for heat-drying of webs, especially printed or inked webs, the web is first subjected to a contactless heat shock treatment, for example by hot air at about 300 DEG  C. It is then heated by a contact process at a lower temperature, for example by heated rollers at about 230 DEG  C., after which it is cooled by a contact process in a third step. Each of the heated rollers may have associated therewith a roller for applying a film of a buffer agent and also a cleaning roller. Energy expended in the processes is recovered by the use of heat exchangers. The apparatus may comprise a closed housing divided into separate chambers within which the sequence of steps is carried out.

Abstract: A high load gas combustion apparatus for use mainly in domestic combustors which require a low noise level and compactness. Some of air for burning supplied from a fan is suctioned to fuel gas jetted through a nozzle to produce a mixture in a mixing tube section, which is then introduced to a mixture chamber defined by a burner body having a uniform shape in the lengthwise direction. The mixture flows into a downstream combustion chamber at a relatively low speed through a flame port section which is incorporated in the burner body on the downstream side of the mixture chamber, and which comprises a number of flame ports having a large opening ratio. The majority of air is supplied to air chambers on both sides of the mixture chamber partitioned by the burner body therefrom. The air chambers and the combustion chamber are partitioned by an air jet plates which includes a number or air ports arranged in zigzag form in the oblique portion thereof and a number of flame retention air ports arranged in the lengthwise direction of the flame port section. Some of the air supplied to the air chambers is supplied under reduced pressure to a flame retention chamber, which is constituted by a recess formed in a part of the burner body on either side of the flame port section, through small gaps formed between the air jet plates and the side wall of the recess, and then flows into the combustion chamber at a lower speed from both sides of the flame port section through the flame retention air ports, thus ensuring flame retension. The majority of the air supplied to the air chambers flows into the combustion chamber through the air ports so as to cross the direction of flow of the mixture for producing steady flames along the air ports arranged in zigzag form, thus greatly enlarging the combustion reaction area.
