Title: Systems for ensuring a cover for a vibration therapy pad is not reused
Inventor: ELLIN PHILIP JAMES
IPC: A61B19/02
Filed: 2008-05-02
Abstract: A cover 150 for a vibrating pad 10 is disabled following a single treatment so that it cannot subsequently be re-used. Preferably, there is communication between the vibrating apparatus and the cover: each may contain an induction loop or radio frequency tag or they may be coupled by a wire (figure 10). After a set period of time (or number of treatments) has elapsed the vibrating apparatus receives a signal to stop vibrating until a new cover is provided. The signal may be from a timer or result from a current spike breaking a fuse wire. Alternatively, the straps 146, 148 that secure the pad and cover to the patient's leg may incorporate a single use adhesive so that they must be cut to remove the pad, or so that the cover or strap tears rather than the adhesive bond failing.

Title: Improvements relating to magnetic blow-out devices for electric circuit interruptersand the like
IPC: H01H9/42
Filed: 1923-03-14
Abstract: 216,474. North, N. E., and Metropolitan-Vickers Electrical Co., Ltd. March 14, 1923. Arc - rupturing devices.-Magnetic blowout devices for switches, circuitbreakers and contactors, of the kind in which the coil producing the blow-out field is connected in the circuit or the arc, the terminals of the coil being connected to arcing segments on which the arc impinges, have more than two arcing segments each connected to a part of the blowout coil so that the blow-out coil is introduced progressively. In Fig. 2, six arcing segments are employed connected to sections of the blow-out coil 8, as shown. The arc is first drawn on to the two segments nearest the main contacts thereby energizing the central portion only of the coil, the blow-out action of which causes further distention of the arc so that it impinges on the central pair, whereupon further sections of the blow-out coil are introduced. Finally, the arc reaches the remote pair of segments and the whole coil is then in the arc circuit. By these means the ampere-turns in the blow-out coil may be kept constant notwithstanding the increasing resistance in the arc circuit as the arc distends. The subdivided blow-out coil in this form may be wholly of high resistance metal or the central portion may be of copper and the outer portions of high resistance metal. The arrangement described is shown, in Fig. 3, applied to a pneumatically-operated contactor switch having fixed contacts 2 with fixed arcing horn 14, and rectilinearly-moving spring contacts 1 with arcing horns 13. The contacts are arranged within the arc shoot 15 in which the arc-excited blow-out device 3 is located. An ordinary series blow-out coil 17 is provided which may be concentric with the coil 8. The coil 8 instead of being located within the arcing segments may be in the positions usually occupied by the. coil 17, connections being arranged between the segments and the tappings of the coil. In this arrangement, shown in Fig. 7, the coil 17 may be dispensed with or may be coaxial with the external coil 8. In the arrangement shown in Fig. 9, six arcing segments are built up, with intervening insulation, to form a conical structure the segments being connected to the tappings of the external blowout coil 8.

The fatty acid compound of the first treatment may be derived from fish oil or a mixture of fatty and resin acids, and the alkali may be sodium hydroxide, calcium hydroxide, sodium carbonate or sodium silicate.  The mineral acid of the second treatment may be sulphuric acid and the cationic-active nitrogenous compound may contain the higher aliphatic amines having 7 to 19 carbon atoms, the condensation products of amino alcohols with high molecular weight fatty acids, the higher alkyl-O substituted iso ureas, the higher aliphatic quaternary ammonium bases and the salts of these compounds with water-soluble acids; the higher piridinium or alkyl quinolinium salts of water-soluble acids may also be used.  A frothing agent, e.g., pine oil, may be used in both treatments.  In the second treatment a small quantity of a salt of a trivalent metal, e.g., aluminium chloride, may be added.  Three examples of the process are given together with the quantities of the reagents used and the results obtained.
Patent GB-428412-A (GB)
Title: Improvements relating to the manufacture of concrete pipes
IPC: B28B21/34
Filed: 1934-04-06
Abstract: Concrete pipes moulded by centrifugal force are subjected to compression by means of internal rollers and also by compressed air or other fluid.  The mould consists of a steel cylinder 2 within which is a roller 7, the position of which within the cylinder can be varied by means of levers 4 which have recesses to support the bearings of the roller.  The levers can be raised and lowered by screw shafts 5, one at each end of the machine, connected by a chain 6a and operable by a handwheel 5a.  A hopper 8 for the concrete carries a distributer 11 which can be rotated by a handwheel 21.  The hopper 8 and roller 7 and counterweights P are supported on a carriage which can be run into and out of the mould 2 on rails 10.  A stop limits the inward movement of the carriage which brings the bearings of the roller 7 over the recesses in the levers 4.  By raising the latter by turning the wheel 5a, the recesses in the levers 4 engage the bearings of the roller 7 and lift them from the carriage which can then be withdrawn with the hopper 8.  The roller bearings are then locked to the levers 4 by hooks 18.  While the charged mould is rotating, the roller 7 is lowered gradually by the wheel 5a to compress the moulded concrete.  The roller 7 is then withdrawn and the fluid pressure device inserted into the mould from the opposite end of the machine.  This consists of a steel tube 15 covered by a rubber tube 13 between which fluid can be forced, and is supported with counter-weights Pa on a carriage running on rails 10a. The tube 15 fits into the mould liner 14 as shown in Fig. 5, a to the width.  The die opening may be larger at its sides in order to apply the material thickly at the edges.
