Title: Loudspeaker crossover networks
Inventor: RICHARDSON WILLIAM GEORGE
IPC: H04R3/14
Filed: 1983-03-17
Abstract: Crossovers employing three- pole filters and a bandpass filter to linearise their input impedance combine a fast filtering action with a range of possible responses and tolerance to variations in component values. The bandpass filter to linearise the input impedance may be constructed using reactances whose values are the same as some of those used in the crossover filters. The network of figure (4) is designed to have a crossover frequency of approximately 3.2 kHz for load resistances, R, of 7.5 OMEGA . Either air-cored or ferrite cored inductors may be used. The extra circuit components to linearise the input impedances of the loudspeaker drive units have not been shown. <IMAGE>

Title: Tyres
Inventor: PICKLES CLIFFORD
IPC: B29D30/00
Filed: 1983-03-25
Abstract: A method of moulding a hollow tyre comprises moulding two parts, at least one having a hollow recess 14 therein, and joining the two parts to form a hollow tyre. The two parts may be joined by means of pegs 17 and sockets 16, by a screw thread, by adhesive, or by passing a heated blade between the two parts. The two parts of the tyre may be identical so that a single mould may be used to produce both parts.

Title: Sealing gasket between apertured plate and pipes
Inventor: KNAPP DR ALFONS
IPC: F16K11/078
Filed: 1984-10-09
Abstract: A sealing gasket A, Fig. 5, between the stationary rigid plaque 2, of a mixing valve and the end openings of the inlet pipes for hot and cold water (not shown) entering the body of the valve, comprises a body of yielding material having two parallel passages (B, C), in which at least a portion of each passage, adjacent to the other passage, has a raised rest part (F, G) arranged to enter the corresponding passage opening (4, 5) of the hard material plaque (2). These raised parts allow the body of yielding material, in case of pressure differences between the two inlet pipes, to discharge the forces onto the hard material plaque, without the yielding body being subjected to deformations such as to jeopardize the sealing action. Furthermore, Fig. 6, the body (A) of the gasket may advantageously have further raised parts (H, J), which extend into the openings (4, 5) of the hard material plaque (2), by forming pre-closure members. <IMAGE>
Patent GB-2150662-A (GB)
Title: Variable ratio lever arm mechanism
Inventor: ENTZMINGER WILLIAM WARREN
IPC: G05G7/12
Filed: 1984-11-22
Abstract: A variable ratio lever arm mechanism typically for use with an overhead valve type internal combustion engine incorporates the concept of shifting the fulcrum pivot point about which a generally linear, elongate lever arm pivots relative to its ends. In its application for use with internal combustion engines, the lever arm as described, otherwise known as a rocker arm, is retained in functional position relative to the valve stem and pushrod, or point of contact of a camshaft acting on the rocker arm. The rocker arm incorporates an essentially elongate through aperture through which the fulcrum rod is functionally positioned, so that the rocker arm may pivot about the fulcrum rod. The fulcrum rod is laterally translatable within the rocker arm elongate aperture in a manner to permit changing of the ratio of the moment arms of each end of the rocker arm relative to the fulcrum rod pivot point. Therefore, translating or otherwise relocating the location of pivot changes the relative arc length of travel of each of the rocker arm ends. In this manner, the amount of valve opening can be altered and controlled for any given constant amount of pushrod reciprocal movement or camshaft action. The laterally shiftable fulcrum rod is retained in functional position within elongate through apertures formed in stationary shaft supports which are mounted directly to the head of the internal combustion engine. The geometric design of these through apertures within the shaft supports dictates the lateral motion of the fulcrum rod in order to shift the pivot point of the rocker arms about the fulcrum rod to effect the desired change in moment arm ratios.

Title: Separating heartbeat sources
Inventor: PEASTON WALTER CAMPBELL
IPC: A61B5/344
Filed: 1985-06-28
Abstract: To separate heartbeat sources, heartbeat pulse signals 3 and 4 are recorded and the time intervals between a series of successive pulses are analysed statistically to determine the number of individual heartbeat sources in the original heartbeat pulse signals. The technique has particular application in determining the number of foetuses being carried by a pregnant ewe. This allows more efficient feeding of the ewes to be carried out. Pulse signals 3 and 4 and noise signals 5 and 6 from microphone 1, electrodes or laser interferometer are filtered at 7 to pick out pulse peaks 3a and 3b. The pulse intervals are timed at 9 and the frequency distribution is produced by a computer 10 which also determines the most probable number of sources. <IMAGE>
