Patent GB-2057763-A (GB)
Title: Rectifier assembly
IPC: H02K11/04
Filed: 1980-09-05
Abstract: A rectifier assembly for installing generators is of asymmetrical construction, that is to say, a second heat sink (12') directly connected to the generator housing, which thereby acts as a supplementary heat sink, is smaller than the first heat sink (11') which is insulated from the generator housing. A rectifier assembly of this kind having diodes (14, 15) on the heat sinks is particularly suitable for installation in three-phase generators for motor vehicles. Angled tabs (21') are stamped from rim portions of the heat sinks and from apertures (22') in an arcuate transition between the body of the heat sink and an axially directed extension. The tabs and the apertures promote the flow of the generator cooling air over the diodes (14, 15) and the heat sinks. <IMAGE>

Title: Ground protection cover
IPC: A63C19/12
Filed: 1980-12-30
Abstract: An unsupported or frameless cover for ground protection of cricket pitches, rugby or football grounds, tennis courts or the like consists of a cover formed by two or more superimposed plies of a semi- permeable or breathable material which are secured together at least around their edge regions but are unconnected one with the other over a major part of their area. In this way. and because of their separate identity, they tend to trap and retain air pockets between consecutive layers as a result of the handling of the cover during laying or application to the ground surface to be protected. One suitable material for the plies is black UV stabilized 100% polypropylene in plain woven form.

Title: Livestock hurdles
IPC: A01K3/00
Filed: 1981-01-22
Abstract: A livestock hurdle (11) is provided comprising a tensioned plastics-material web (1) carried by a substantially rigid frame. The web (1) is preferably apertured. The frame includes two uprights (3) spaced by cross-bars (7) and in one embodiment the uprights (3) are connected to the web (1) by being threaded in and out of the apertures (2) provided in the web (1). In another embodiment of the hurdle (Fig 2 not shown), the web (1) is connected to the uprights (3) by being passed therearound and fastened back onto itself. Various expedients can be used to ensure satisfactory tensioning of the web (1); thus, for example, after connection of the web (1) to the upright (3) the web (1) may be subjected to a heat treatment process to cause it to contract and become taut. Releasable clips can be provided to join the hurdles (11) together to form livestock pens or windbreaks. <IMAGE>
Patent GB-2070002-A (GB)
Title: Method for manufacturing ethyleneglycol
IPC: C07C27/00
Filed: 1981-01-28
Abstract: A novel and very economical method for the industrial production of ethyleneglycol starting with formaldehyde and synthesis gas, i.e. a gaseous mixture of carbon monoxide and hydrogen, is provided. The method utilizes the synthetic route in which a formaldehyde di-sec-alkyl acetal, which is obtained from formaldehyde and a sec-alcohol, is reacted with carbon monoxide and hydrogen to form an ethyleneglycol mono-sec-alkyl ether which is then hydrolyzed with water into the desired ethyleneglycol. The first step reaction of the acetal compound is catalyzed with a single component catalyst of cobalt carbonyl while the hydrolysis reaction proceeds with an acidic catalyst in a high yield unexpected from the similar reaction ethyleneglycol mono-primary-alkyl ethers.

Title: Improvements in or relating to stirling cycle machines
IPC: F02G1/043
Filed: 1981-06-25
Abstract: The compressor/expander 2 is in driving connection with a first electromagnetic unit 13, and a second electromagnetic unit 17, 18, 19 is connected to the displacer 1 and can be operated as an externally-variable control of the movements of the displacer. In one form of the invention the second unit acts as an electromagnetic damper upon movements which the displacer makes in natural response to those of the compressor. In another form of the invention the second unit positively derives the displacer and the two units are interconnected by means including a phase-shifting device 28 whereby movements of compressor and displacer are kept of equal frequency but variable as to phase difference. Transducers (46, 47) sensitive to position, velocity or acceleration may improve control of the movements of compressor and displacer, and a temperature sensor (48) associated with the "cold finger" 8 of the displacer may further improve control of the movements of the latter. <IMAGE>

Title: Method and apparatus for automatically tensioning threaded fasteners
IPC: B25B23/14
Filed: 1982-03-30
Abstract: Automatic tensioning of threaded fasteners is effected using a microcomputer. The torque and rotation are measured and, when the linear part 52 of the curve is reached, the curve is extrapolated back to the snug angle SA. The fastener is then rotated a predetermined angle from there. In another embodiment, tightening is stopped when the curve begins to deviate more than a certain amount from the linear part (part 58, proof load region). In another embodiment the degree to which previously installed fasteners have been tightened is checked. <IMAGE>

Title: Load-measuring devices
Inventor: SANSOME DENNIS HUGH
IPC: G01L1/22
Filed: 1983-09-30
Abstract: A ring-shaped device to measure the load between bodies 3, 4 located on opposite axial sides of the ring 1 and in engagement with it, the load being in a direction coaxial with the ring. The load causes the ring to distort, and the radial section of the ring is such that the distortion places part of the section predominantly into hoop tension and another part predominantly into hoop compression; separate sets of strain gauges 13, 14 sense these two conditions and the outputs of the two sets are combined to give an indication of the load. The ring may for instance have the shape of a pear or dumb-bell when viewed in radial section, the long axis of the pear or dumb-bell being inclined to and intersecting the ring axis. <IMAGE>

Title: Generating rotational speed data for an internal combustion engine
Inventor: IZUMI KOUICHI
IPC: F02D45/00
Filed: 1984-01-09
Abstract: A rotational speed data generator obtains engine speed data wherein the pulsating component in the speed of an i.c. engine is eliminated. The data generator has a rotational speed sensor outputting a pulse every predetermined rotational angle of a crank shaft of the engine, a circuit for obtaining period data representing the period of generation of the pulse, a circuit responsive to the period data for computing average speed data, a circuit for computing the rate of change with time of the engine speed on the basis of the average speed data, and a circuit for obtaining engine speed data by amending the average speed data according to the rate of change to correct an error of the engine speed represented by the average speed data. Therefore, stable control of the operation of the engine can be realized without degrading the response characteristics by using the engine speed data obtained from the data generator.
