Title: Explosive fuse made from non-flowable powder - by entraining twisted threads and simultaneously stirring powder
IPC: C06C5/08
Filed: 1971-05-03
Abstract: The Parent Patent describes a method of making an explosive fuse of very fine granular or pulverulent, non-flowable explosive, in which the powder is passed downwards through a hopper into a continuously produced tube or sleeve, a number of threads being simultaneously pulled downwards and twisted together through the powder, so that by the combined effects of vibration and the roughened surface of the threads the powder is pulled into the tube. In the Patent of Addition, one or more stirring rods move inside the hopper, pref. revolving with the filaments, the outlet of the hopper being pref. adjustable to meter the quantity of powder leaving it. The stirring rod is pref. very close to the hopper wall and parallel to it.

Title: Coaxial connector with radially-acting contact ring - connects bared outer conductor to outer end collar coupled to union part
IPC: H01R13/646
Filed: 1971-07-05
Abstract: The coaxial connector has a radially sprung contact ring (18) contacting with the bared outer surface of the coaxial cable outer conductor (14) and electrically connecting it to the end collar (28) that will eventually be mated with the other half of the connector. The fable insulating sleeving (16) penetrates beneath a rear tube (34) sealed (56, 40) to it and to the end collar. The inner conductor (10) passes into the collar where it mates with, in this case, the plug pin (44). The pin passes out of the collar into the union part of the connector which mates with the corresponding socket.

Title: Test system for mark to space ratio of telephone dialling pulses - gives reading for individual pulses using gated counters controlled by oscillator
IPC: H04M1/24
Filed: 1971-11-26
Abstract: Telephone-type dialling pulses (NS) at the input of the tester are counted (Z) and displayed (a1), (a9). The pulses are also routed to a gate (T) whose outputs feed an impulse counter (JZ) and period counter (PZ). An oscillator controls the gate. Intermediate registers (JS), (PS) are connected to a divider network (R) whose outputs operate display devices via drivers (AS1), (AS9). The counter output also operates a comparator (V) which indicates if the pulse waveform is within the required tolerance. If the pulse counter (JZ) is a count-up circuit and the dwell counter (PZ) is a countdown type, the arithmetic unit (r) operates as an add-subtract circuit.

Abstract: A heat exchanger core made up of a loose stack of heat exchange sheets is surrounded by a support frame which holds the sheets against separation. One end of the support frame is mounted on the engine body and restrained against vertical, fore-and-aft and sidewise movement relative to the engine body. The other end of the support frame is mounted on the engine body by a double pivot link assembly which restrains that end against vertical and sidewise movement but allows fore-and-aft movement. A simple expansion bellows joins the high-pressure air inlet of the heat exchanger to the engine body. A simple expansion bellows may be used to join either or both of the high-pressure air outlet and low-pressure hot exhaust gas inlet of the heat exchanger to the engine body.

IPC: C07C31/04
Filed: 1981-02-13
Abstract: A process for the production of olefins from synthesis gas comprises a first synthesis stage in which a mixture of methanol and higher alcohols are formed from a synthesis gas comprising hydrogen and carbon monoxide. The catalyst for the first synthesis stage comprises the oxides of copper and zinc in intimate association with each other and a promoting compound selected from the group consisting of chromium, cerium, lanthanum, manganese, thorium, and an alkali metal. The materials from the first synthesis stage are separated into a gas phase and a liquid phase. Thereafter the methanol is separated from the higher alcohol fractions. The higher alcohols are then subjected to dehydration in a dehydration stage which comprises passing the higher alcohol fraction over an alkalized dehydration catalyst at a pressure in the range of 0.5-1 bar and a temperature in the range of 350 DEG -500 DEG  C. Thereafter the olefins produced by the dehydration of the higher alcohols are separated into the olefinic and non-olefinic materials. Preferred dehydration catalysts include alkalized aluminum oxide and alkalized calcium phosphate.

Abstract: A fluid dispensing applicator for crease setting compositions comprises a support 16, a reservoir 12 slidably mounted on the support 16, an applicator nozzle 14 connected to the reservoir 12 to deliver fluid therefrom, and a bearing element 40 movable relative to the support 16 between retracted and advanced positions capable of effecting slidable movement of the reservoir respectively towards and away from the support 16 when so moved. A rotatable member 18 is mounted on the support and is geared to a piston arrangement 32, 34 for urging fluid from the reservoir 12 through the nozzle 14. The nozzle 14, bearing element 40 and the periphery of the rotatable member 18 are aligned on the same side of the applicator. When the applicator is not in use a combination of the pressure within the reservoir 12 and gravity cause the bearing element to move the reservoir into the retracted position thereby relieving the pressure in the reservoir and preventing oozing of crease setting composition from the nozzle 14.

Abstract: The apparatus for winding flexible material on to a mandrel provides a control system for automatically controlling the packing density of the wound material. The mandrel (M) is rotatably mounted on one end of an arm (A) which is mounted to pivot about a horizontal axis (F) at the other end of the arm. The package being wound rests on a bar (PB) and pressure is applied to the periphery of the package by a weight (W). The effect of the weight (W) is reduced by a piston slidable in a cylinder, air pressure (p) being applied to the underside of the piston. The air is provided by means of a pump driven by an electric motor through a mark-space control. This control varies the means speed of the pump in dependence on an error signal derived from the difference between the output of a load sensor and a reference value. In addition, the reference signal may be varied by means of a measurement of the diameter of the package.

Abstract: Immunoassay methods utilizing HCV envelope antigens that contain conformational epitopes reactive with antibodies in serum from infected individuals are useful for screening and diagnosis. These antigens detect antibodies that are not detected by denatured HCV envelope antigens.

This is the first evidence that conformational epitopes may be involved in the immunologic response to HCV antigens.

Abstract: Computer systems and processes are disclosed for recovering a failed commit procedure. A first recovery facility collects and compares sync point state information from a variety of different types of resources including a data repository and a protected conversation. The comparison of the sync point state information is made automatically in response to a sync point failure event. A second recovery facility serving another execution environment notifies the first recovery facility after a failure and subsequent recovery procedure of the second execution environment has completed. The first recovery facility makes automatic cyclic attempts to communicate with the second recovery facility. The first recovery facility can receive a manually initiated but automatically simulated response of sync point state information when there is a failure such that actual sync point state information cannot be received. The first recovery facility is responsive to the simulated sync point state information to proceed with a recovery operation substantially as if actual sync point state information were received. <IMAGE>

Abstract: Clay convertible by thermal treatment into crystalline mulite and silica is formed into green coherent bodies of desired size and shape such as for example, microspheres, pellets or honeycombs. The bodies are then calcined to convert the clay into a mixture of crystalline mullite and silica, thereby also hardening the bodies. Without destroying the form of the bodies, e.g., without grinding and without causing the bodies to decrepitate, pores in the size range of about 150 to 350A are formed by selectively leaching silica from the bodies. The porous mullite bodies retain porosity at elevated temperatures and are useful, for example, as catalyst supports and contact materials. Pore structure in the meso- (100-600A diameter) and macro- (600-20,000A diameter) size ranges may be controlled.
