Abstract: 1,188,419. Wells. B. BONNEVALLE. 29 Oct., 1968 [2 Nov., 1967; 7 Dec., 1967], No. 51218/68. Heading E1F. The water bearing stratum around a water well is cleaned by injecting a mixture of air and water under pressure into the stratum through the drain openings of the well lining so as to dislodge the fine particles which clog the interstices in the stratum and then removing the water and particles from the stratum. The water and air may be injected through a pair of parallel pipes held by a diver in the well. The injected water and particles may be removed by suction through a third pipe having a filter screen at the inlet. The three pipes may be concentrically arranged. Water may be passed from the water pipe through a valve and side pipe to the suction pipe to clean it. Alternatively the injected water and particles may flow into the well by lowering the water level therein.

Title: Ultrasonic seaming apparatus

Filed: 1971-11-23
Abstract: 1322849 Seaming non-metallic sheet material BRANSON INSTRUMENTS Inc 23 Nov 1971 [27 Nov 1970] 54348/71 Heading B5K In a method of ultrasonically seaming a workpiece fed continuously past a resonator 22, the velocity at which the resonator 22 resonates is adjusted in dependence upon the rate of which the workpiece is fed past the resonator. The velocity of the resonator is the peak displacement amplitude at the output surface of the resonator per unit of time in a direction toward the workpiece. The resonator 22 is vibrated by a magnetostrictive or piezoelectric transducer supplied with high frequency electrical energy and its work surface is mounted to form, with a rotatable anvil wheel 24, a nip through which the material to be bonded, e.g. woven fabric made wholly or partially of thermoplastic fibres, is passed. The work surface of the resonator is disposed at an antinodal region. An electrical power supply 26 is mounted to the work-table 12 and supplies h.f. energy to the transducer. A foot control 28 is connected by a rod 30 to a control box 32 which has a dual function i.e. controlling the feed rate of the material and controlling the velocity of the resonator 22 in a predetermined and co-ordinated manner such that the velocity of the resonator increases linearly with increasing feed rate but at a rate which is less than the increase of the feed rate. As shown in Fig. 2, the wheel 24 is mounted on a shaft 36 extending from a gear reducer 38 driven by an electric motor 40 and is exchangeable for a wheel having a different raised pattern thereon, for examples see Fig. 3. When a knee operable control 34 is moved to the right against the action of a spring 44, a switch 46 is actuated to actuate a solenoid valve (not shown) to cause a piston working in a cylinder to lift the resonator 22 by a predetermined amount to facilitate insertion and removal of workpieces. Electrical circuits (n.s.) for the control of the machine are described.

Title: Improvements in magnetic circuit elements
IPC: C23F1/02
Filed: 1969-11-12
Abstract: 1282028 Magnetic storage devices THOMSON-CSF 12 Nov 1969 [14 Nov 1968] 55478/69 Heading H3B [Also in Division H1] In a method of making a magnetic circuit element 10, Fig. 4, having primary and secondary turns 1001, 1002, photogravure techniques are used to electrodeposit alternate layers of an inert metal (dark areas in Fig. 9) and a reactive metal (lighter areas) on both sides of a substrate, following which the assembly is etched to form a body of substantially rectangular cross-section around which magnetic material is deposited, the reactive material eventually being etched away and replaced by insulating material to form an elongated magnetic cylinder within which inert metal conductors are supported. The elongated element, which is used to couple control pulses to a data store word line, is stated to give an increased flux linkage between primary and secondary over a conventional torroid without increasing switching times. The inert metal may be gold or silver, the reactive metal is copper, and the substrate may be copper, nickel plated copper, or magnetic material as used in the rest of the element. Only in this latter case is the substrate not eventually etched away. Fig. 9 shows eight gold conductors on a central copper substrate, and the assembly is shown in plan in Fig. 14 after rectangular areas A, B and C of photoresist have been formed. The assembly is then etched in a copper solvent to form slots 504, 505, Fig. 15, by which the conductors are laterally separated from the copper side regions of Fig. 9. The copper at the ends of the assembly, and beneath areas A, B and C is not etched, thus maintaining the position of the gold conductors. The block of conductors is then copper plated to give it a rectangular cross-section, Figs. 18, 19 (not shown), but slots 504, 505 are not greatly affected. Magnetic material is then deposited around the plated block, except at areas A, B and C, Figs. 18, 19 (not shown). Removal of the photoresist in areas A and C allows the adjacent copper within the magnetic shell to be dissolved and replaced by insulating material such as photoresist. During this operation, holes are also formed through the ends of the assembly where the copper still supports the gold conductors. These holes are filled with insulating material and the copper is etched away. As a final step, the photoresist over area B is removed and all the remaining copper within the magnetic shell is dissolved and replaced by insulation. The gold conductors may be linked together by etching holes through adjacent copper and gold layers as they are deposited in the formation of the assembly of Fig. 9. When the next gold layer is deposited it forms an eyelet in the hole and connects the layers electrically, Fig. 13 (not shown). In other embodiments, at least some of the copper may be replaced by insulation prior to forming the magnetic cylinder.
