Abstract: ABSTRACT OF THE DISCLOSURE           A pulse combustion heater is described and includes a combustion chamber and at least one exhaust pipe forming a resonant system with a chamber.  In one aspect of the invention, the combustion chamber has an internal cavity of flattened spherical shape which causes combustion gases returning to the combustion chamber to flow into said cavity in a double toroidal flow pattern. In another aspect, the apparatus has an exhaust system which includes a primary exhaust pipe of a length selected so that combustion of gases is at least substantially complete before the gases leave the pipe.  The pipe terminates at a manifold to which is connected a plurality of heat exchange coils of helical shape from which heat is transferred to a fluid circulated around the coils. According to another aspect of the invention, the heater has a three part housing, upper and lower parts of which are concrete castings and define respectively an air cushion chamber and an exhaust chamber of the heater.  A center section forms part of a boiler sub-assembly which isolates the exhaust chamber from the air cushion chamber. In another aspect, a unitary gas cushion chamber sub-assembly is described.

Abstract: ABSTRACT OF THE DISCLOSURE           A heat shield arrangement for strip material employs insulating panels that include an upper series displaceable upwardly by power actuation means to avoid damage by buckled or lifting material.  Protective elements projecting below the upper panels are associated with sensing means to actuate the raising of the upper panels and are on mountings able to have a limited displacement before the raising of the upper panels is actuated.  The power actuation means act on said mountings to determine the minimum force from the material that causes raising of said panels.  To lead in deformed stock there is an increased height entry region comprising a reinforced upper structure, possibly followed by upper and lower insulating panels at decreasing heights from each other to merge into a main region of limited height. The panels may have heating means to give the strip a more uniform transverse temperature profile.

Abstract: ABSTRACT        The invention is concerned with the rapid release of frictional force which is acting to reduce relative movement between contacting surfaces, the normal actuating means being unaffected.  One application is in an anti-lock braking system in vehicles, particularly motor-cycles. A sensor monitors wheel angular velocity and when this falls below a pre-determined value the sensor causes ultrasonic vibrations to be applied to brake pads effectively reducing friction without release of brake operating pressure to enable resumption of normal rotation.  A short duration dc pulse of appreciable magnitude may be applied to the trans-ducer at the onset of the normal input signal to produce a short duration surge to rapidly break the frictional force between the friction member and the moveable member to enhance speed of release.  The transducer may also be applied directly to the end wall of a friction member hydraulic operating cylinder when ultrasonic vibrations will be transmitted through the operating fluid to the piston connected to the friction member.  The end wall of the cylinder is of a suitable matching material to facilitate transmission of the ultrasonic energy and the piston is formed so as to minimize attenuation.  The invention can also be applied to friction clutches operating in either rotary or linear senses to cause release when overload-ing, overspeed   etc   occurs or give gradual engagement in accordance with a predetermined programme.

Abstract: ABSTRACT OF THE DISCLOSURE The   tubular   sealing element consisting of flexible material, between a cylinder and a piston as working members for the formation of a pressure working space is connected by a connection of the substance of the material, in particular by a vulcanized connection (10) to one working member (1) which forms a bearing surface (4) for the sealing element under the action of the working pressure.  This connection makes possible secure closure and gentle introduction of the stresses into the flexible material of the seal. Preferably the connection area (11) of the working member (1) is made toroidal with a uniformly curved profile, whereby stress concentrations in the connection region are reduced.  In addition a compressive prestress of the material of the seal may be provided in the connection region between corresponding solid bodies (1a, 11a) with the advantage of the additional safety and the closure of the connection of the substance of the material, against attack by a lubricant introduced if necessary between the bearing surface (4) and the sealing tube (3).

Culley SWITCHING NETWORK WITH IN-BUILT FAULT IDENTIFICATION       In modern digital telecommunications switching networks the switch block may be a duplicated plane time-space-time arrangement in which each time switch stage and each space switch stage is controlled by control stores.  Each control store is cross-office slot ordered and is arranged to be loaded by the central control with the identity of the connection required for the relevant cross-office slot.  At each busy cross-office slot in a time switch control store a 12 bit address word is retrieved.  Ten bits are used to define the connection while the two remaining bits act as a busy bit and a parity bit.  Each space switch control store contains in cross-office slot order eight bit address words (6 bits address plus busy and parity bits).  The busy bits are used when interrogating the trunking for free paths and they are also used to control the application of idle codes to free slots in the speech path.  The parity bits within the control stores are used to initiate pattern insertion on the speech highways. The detection of "bad parity" causes characteristic patterns to replace an erroneously accessed samples at the time or space switch and the replaced sample will be intercepted at the transmit digital line termination unit, which will be biased to choose  the sample-from the other plane of the switch block. The inserted pattern also identifies the trunking element to which the erroneous address has been applied so that the DLT is able to indicate the faulty control store.

Abstract: TIMING OF ACTIVE PULLUP FOR DYNAMIC         SEMICONDUCTOR MEMORY     ABSTRACT OF THE DISCLOSURE     A method for operating a dynamic semiconductor memory circuit (10) having a memory cell (12) which comprises a access transistor (12a) connected to a half digit line (18) and a storage capacitor (12b). Each of the half digit lines (18, 22, 60 and 62) is charged or discharged as a result of either read operations carried out with the corresponding memory cells or write operations receiving incoming data states through input/output lines (42, 46).  The charged state of the half digit line (18, 22, 60 and 62) is at a voltage substantially below that of the supply voltage of the circuit (10).  After the half digit lines (18, 22, 60 and (62) are sensed and/or written to the desired states, a pullup circuit (48) for each of the half digit lines (18, 22, 60 and 62) charges the half digit lines with voltages above a predetermined threshold to the full supply voltage.  A word line signal (72) couples the charge storage capacitor (12b) to the corresponding half digit line (18) to transfer the full supply voltage of the circuit (10) into the storage capacitor (12b).

Abstract: D-4,444  C-3254 LOW TIRE PRESSURE TRANSDUCER Abstract of the Disclosure A low tire pressure transducer coupled to a tire rim includes a diaphragm subject to tire pressure on one side and to a mechanical spring force on the other side.  A magnet within the transducer is coupled with a shunt which minimizes the external magnetic field when tire pressure is at its proper value.  However, movement of the diaphragm occasioned by low tire pressure also moves the shunt so that the external magnetic field increases substantially.  Movement of the shunt also opens a valve which relieves any air pressure buildup in the transducer on the spring side of the diaphragm thereby avoiding premature actuation of the transducer due to air leakage into the transducer.  A retaining ring holds the transducer to the rim and contains vents for allowing the exhaust of air from the transducer.
