Title: Positive drive whip rod for heat transfer apparatus
Inventor: LI YAO-TZU
IPC: F25C1/14
Filed: 1994-06-16
Abstract: A heat transfer apparatus for processing a liquid continuously has a positive mechanical drive for a set of vertical whip rods each disposed in a vertical heat transfer tube. Each whip rod is free-standing on its lower end and is sufficiently flexible to conform closely to the inner surface of the tube as it orbits. The orbital drive propels the whip rod directly through a pair of horizontal, vertically spaced plates that engage the rods in loose openings that serve as fluid inlets from the drive plate. A motor rotates a drive shaft coupled to at least one of the drive plates through at least one eccentric crank. Each plate can be an opposed pair of plates with a separate eccentric drives 180 DEG  out of phase with one another for a self balancing. Another form of drive plate uses a rigid circular ring that mounts rod-engaging sleeves via a network of wires supported by the ring. Fluid distribution can also be from a water supply held between a fixed plate and the upper drive plate with gravity feed to each tube through a properly sized inlet opening in the upper tube end. To isolate the heat transfer process, various seals are used to transmit rotary power through a housing without conventional rotary seals.

Abstract: An induction heating appts. for plastics extruders employs induction coils with E-shaped cores. The coils are mounted in a 2-piece housing which is clamped on the extruder barrel by spring tension. The extruder barrel (1) is heated by induction coils (2,2a,3,3a) in which the coil is wound on the central arm (4,4a,5,5a) of an E-shaped laminated iron core. The coils are magnetically coupled to the barrel by an interlayer (6,6a,7,7a) which covers the core. Pairs of coils are mounted in a 2-piece housing (8,9) which is assembled and clamped on the barrel (1) periphery by means of threaded pins (13), carrying washers (15) and nuts (16,17). Disc spring stacks (14) are interposed between the washers (15) and housings (8,9), so that the housings and coils are urged into contact with the barrel by spring pressure. In another embodiment, the appts. may be adapted to a cylindrical extruder barrel.

Title: Carob flour prodn.

Granted: 1987-09-30
Abstract: The data reduction apparatus is used in a system where speech signals, e.g. between telephones, are digitised in a circuit and later reconverted. Successive blocks of digitised data, e.g. 16m seconds thereof, are compared with each other in the frequency domain in a comparator. The conversion is effected in a circuit block. If one block is similar to its predecessor within pre-set limits, that block is not sent to the output, and instead a control signal is passed to the communication link to instruct a store to repeat the previous block at the other end of the communication link. Thus only critical data blocks are transmitted and the data rate is reduced.

Granted: 1986-09-24
Abstract: Methyl tert-butyl ether (MTBE) is prepared by the selective reaction of methanol with isobutylene contained in a hydrocarbon fraction with four carbon atoms (C4fraction, or C4hydrocarbons), operating in the liquid phase under the influence of acid catalysts. The reaction mixture containing MTBE together with methanol and C4hydrocarbons is distilled, preferably at increased pressure, with separation of the methanol and the C4 hydrocarbons at the head and of MTBE at the bottom of the distillation column. This operation is carried out with an additional lateral liquid flow of a C4 hydrocarbon, or mixture of C4 hydrocarbons, to the column so as to maintain a methanol-C4 hydrocarbon composition in the column at all times with a greater than azeotropic C4 hydrocarbon content at the operating pressure. According to a preferred embodiment the distilled C4 hydrocarbons, after separation from the methanol, are recycled as the lateral flow to the distillation column. It is thus possible to separate MTBE completely in a single distillation operation with a high purity as the product at the bottom of the column.

Title: Electrical coupler of loose components held in position - has drive member rotating around shaft and engaging member pressing against coupler
Filed: 1975-01-31
Granted: 1979-03-10
Abstract: The electric coupler consists of two loose components which are prevented from unintentional separation or decoupling. It consists of a drive member (19) which rotates about a shaft and an engaging member (98) which moves with the drive. The engaging member presses against a section (100) of the screw coupling (66) enabling it to move in a given direction. There is a wedge-shaped member (110) which can move along an arc relative to the screw coupling and the drive. The wedge-shaped member prevents decoupling of the drive and driven members. The wedge-shaped member can be put out of action by the engaging member, when the drive is rotated in the opposite direction.

Abstract: 1360546 Balances; poising TIMEX CORP 3 Feb 1972 [10 Feb 1971] 5185/72 Heading G3T To permit poising of a balnce 10 carrying a coil 13 or other body which may vary in weight, the rim 11 has an offset counterweight portion 26 which is of crescent shape and introduces a degree of unbalance such that, when suspended with its axis horizontal, the balance takes up an appropriate angular position opposite a fixed tool 29. Actuation of the tool then removes an amount of material from the periphery 27 of the portion 26 to partly or wholly poise the balance. In the former case there may be a second, fine poising operation. Fig. 2 shows the position taken up by a balance having a coil 13 of minimum possible weight, and Fig. 3 the position with a coil of maximum weight. The method of calculating the balance dimensions, e.g. of spoke 23 and the periphery 27, is described. The body may alternatively consist of a pair of magnets (40), Fig. 10, (not shown), on a balance disc (41) which includes a specially curved external peripheral portion (42).
