Title: A fuel supply system for an engine
IPC: F02M51/00
Filed: 1980-04-01
Abstract: A fuel supply system for an engine includes means defining a cavity 12 which communicates by way of an orifice 15 with a combustion chamber 10. A low- pressure fuel pump 17 supplies fuel to the cavity via a non-return valve 18 at a time when the pressure in the combustion chamber is low, e.g. towards the end of the suction stroke. Located in the cavity is an electrode 14 insulated by an insulator 13 from the wall of the cavity. With fuel in the cavity a spark discharge is caused to take place between the wall of the cavity and the electrode and the fuel and also air in the cavity expand through the orifice into the combustion chamber. <IMAGE>

Title: Brake Booster Assemblies
IPC: B60T13/56
Filed: 1980-11-07
Abstract: In a brake booster a resilient buffer 104 is located between a power piston 28 and an output member 106. An outer peripheral portion 98 of the buffer is acted upon directly by the power piston and is compressed on initial brake application. The remainder of the buffer is acted upon by the power piston through a plate member 102 only after initial movement of the power piston and therefore only after initial compression of the outer peripheral portion of the buffer. Axial movement of the plate member 102 relative to the power piston is limited by a shoulder 100 of the power piston, so that the extent of the differential compression of the buffer is limited to an acceptable minimum. <IMAGE>

Patent GB-2101413-A (GB)
Title: Compressor
Inventor: FANNIN THOMAS
IPC: H02K9/19
Filed: 1981-05-05
Abstract: A compressor includes an electric motor (3) comprising a rotor (9) and a stator (10). The motor drives a rotary vane compressor (2). The rotor of the motor has one or more passages (11) extending through it, and tubes (12) are fitted into the lower ends of those passages. Each tube (12) is closed at its lower end (13) but has an opening (14) in the leading section of its curved wall. Tubes (12a) are fitted into the upper ends of the passages (11), and these tubes are open at the top end. When the rotor rotates, oil (15) in a sump (16), which is cooled by a pipe (17) containing liquid refrigerant, is forced up the tubes (12, 11, 12a) and emerges in a jet at the top. The bearing for the rotor shaft (9a) is thereby lubricated, and the winding (10a) of the stator of the electric motor are also sprayed with oil. In this way, the windings are cooled without the need to provide a separate pump for supplying cooling fluid. <IMAGE>

Title: Heat Transmitting Elements for Regenerative Heat Exchange
IPC: F28F21/00
Filed: 1981-07-20
Abstract: The elements are in the form of rigid hollow balls (1), the interior of which are wholly or partially filled with a latent heat storage material. Heat transmission from a hot to a cold region is effected by cyclic transport of the balls between the hot and cold regions by means of a Ljungström heat exchanger or in a column heat exchanger. The balls are cleaned by frictional contact with one another as a result of their movement in a fluidized bed in the exchanger, or by rotation of a static bed in a rotary heat exchanger. The heat storage material may be a metal or a chemical compound, e.g. LiH, LiF or MgF2. <IMAGE>

Title: Wearable insulin infusion system having a tubular reservoir and a positive displacement metering means
IPC: A61M1/00
Filed: 1980-12-09
Abstract: A wearable infusion system for delivering a fluid medication such as insulin to a patient through a needle, cannula or catheter (28). The infusion system includes a medication-filled elongate, thin-walled tubular reservoir (40) and a positive displacement metering assembly (22) operated by a power source under the control of a controller such as a microprocessor (24). The positive displacement metering assembly (22) draws the reservoir (40) inwardly between squeeze surfaces (56) which forces the medication toward the remote end where it discharges through an associated cannula, catheter or needle (28) into a patient. The rate and frequency at which the metering assembly is operated controls the rate and frequency at which the medication is delivered to the patient. The tubular reservoir defines a plurality of loops (48) so that a maximum amount of fluid medication may be disposed in a housing.

Title: Measuring temperature electrically while welding plastics
IPC: B29C65/34
Filed: 1982-01-19
Abstract: In the welding together of plastics pipes (10, 14), a band (16) of electrically conductive material locates between the pipes at the joint and the latter is surrounded by a coil (18). A voltage is applied across a tuned circuit including the coil (18) and current is induced in the band (16) to heat the joint to the fusion temperature. The magnetic permeability of the band (16) alters and the effect on the tuned circuit results in changes in the phase angle of the coil voltage relative to the applied voltage. Comparison of the phase angles can give an indication of the temperature of the band (16) and further comparison with a reference can produce a signal for controlling the applied voltage and thus the temperature of the band (16).
