Title: Water heater having immersed electrodes
IPC: F24H1/10
Filed: 1975-02-26
Abstract: 1486346 Electrode boiler A CURCHOD and A LUPORINI 26 Feb 1975 [5 March 1974] 7942/75 Heading H5H In a three phase delta connected electrode boiler comprising an insulating support 1 carrying three pairs of equispaced electrodes 11/12, 13/14, 15/16, in which the electrode pairs 11/12, 13/14, 15/16 are connected to the respective phases 17, 18, 19, and a second insulating support 4 carrying three pairs of equidistant electrodes 24/25, 26/27, 28/29 in which the electrodes of each pair 24/25, 26/27, and 28/29 are connected exclusively to one another by respective conductors 31, 32, 33, one of the supports 1, 4 is movable relative to the other to modify the current flowing through water passing between them. As shown, the supports 1, 4 are coaxial cylinder which are relatively angularly adjustable to control the current flow and hence the temperature of the water. Alternatively the supports may be parallel flat supports carrying the pairs of electrodes, and the adjustment may be effected by moving one flat support rectilinearly in its own plane or by rotating one support if it is the form of a disc. A servomotor controlled by a thermostat and a parametric resistance may effect adjustment of the supports automatically. In operation from cold, the supports 1 and 4 are adjusted so that each pair of electrodes on support 4 is opposite the electrodes of adjacent pairs of the phase connected electrodes so that maximum current flows. The supports assume a position in which the electrodes on one alternate with those on the other when the desired water temperature is reached. Thyristors 21, 22, 23 connect electrodes 11, 13 and 15 to their respective phases to limit the maximum current supplied.

Title: Magnetic flying-head devices
IPC: G11B5/31
Filed: 1974-02-21
Abstract: 1456705 Flying head assemblies COMPAGNIE INTERNATIONALE POUR L'INFORMATIQUE 21 Feb 1974 [21 Feb 1973] 7997/74 Heading G5R A flying-head assembly for magnetic disc equipment has a magnetic head 1 bonded in a hole in a dielectric carrier plate 10 by means of solder 11, 12, 13 located between and bonding together films 8, 9 of high permeability anisotropic material respectively on the wall of the hole and on that surface of the head 1 in said hole, the head 1 having an external electrically insulating coating over which the film 9 is deposited. The head 1 may comprise a transducing gap defined by two ferromagnetic layers 2 encapsulated between glass blocks 3, 4 and containing part of a flat spiral coil connected to leads 5, (6), (7), Figs. 1, 2 (not shown). A solder film 11 is formed over the magnetic film 9 of the head and a solder film 12 is formed over the magnetic film 8 of the carrier plate hole. With the head located in said hole the structure is heated while additional solder 13 is caused to flow between solder films 11, 12, thus bonding the head to the plate 10 on cooling. The films 8, 9, 11, 12, 13 form a magnetic and electrostatic shield, additional shielding being provided by continuations 14, 15 of films 8, 12, and by soldering a ferrite cup 18 shield to film 15 or providing continuations 17 of films 9, 11 over the rear of head 1. The magnetic and solder films may be formed by cathodic sputtering in vacuum, the films each being about 5 microns thick, and the process may also yield terminals (20), (21), (22), Fig. 1, located on a rear surface of plate 10 and each formed by a solder film over a magnetic film, leads 5, (6), (7) being connected to the terminals, and terminal (20) being earthed with the films thereof being continuous with films 14, 15. Monolithic integrated amplifier circuits may be directly applied over said terminals.

Abstract: 980,450. Cutting machines. F. L. SMITHE MACHINE CO. Inc. Feb. 28, 1963. No. 8135/63. Heading B4B. A rotary cutting apparatus, for cutting window openings in envelopes, comprises a cylinder 30, Fig. 1, having a knife 46 which co-operates with a backing-roller 20 and has those portions which are disposed transverse to the axis of the cylinder provided with a greater clearance relative to the coacting surface of the backing roller than those portions extending longitudinally of the cylinder as to provide for substantially uniform cutting pressures along the cutting edges. The blanks 22 are fed by chain-conveyers 12, 14, having locating pins 24, 26, between rubber ring- members 58 on the cylinder and the backing roller. The blade is secured by adhesive on a mounting block 50, Fig. 3, which is attached by bolts 54 to shells 42 clamped on the cylinder 30 by bolts 44. The inside of the cylinder is provided alternately with air pressure and suction via a rotary valve 36, Fig. 1, and, through openings 56 in the mounting block 50, is arranged to provide suction to hold the cut waste panel on the cutter during cutting and pressure to discharge the panel into a container below the feed line. The desired uniform cutting pressure along the edges of the blade is provided by so grinding the blade that the portions extending transverse to the axis of the roller 30 extend radially outwardly less far than the portions extending parallel to this axis, such an effect being achieved by grinding the trans 1  verse portions so that they have a radius of curvature greater than that of the longitudinal portions, as shown in Fig. 12. The blanks are fed to the knife by the pins 24, 26 somewhat askew to the line of travel of the conveyers 12, 14 and the knife is arranged in the cylinder in correspondingly-skewed position. The mounting block may be modified by providing a flat ledge on which the cutting blade is positioned, Fig. 6 (not shown), and the knife may be formed of a number of sections.

Title: Improvements in and relating to temperature control systems for electric heating elements
IPC: G05D23/22
Filed: 1953-03-30
Abstract: 728,479. Automatic temperature control systems. GENERAL ELECTRIC CO. March 30, 1953 [April 3, 1952], No. 8706/53. Class 38 (4). [Also in Group XXXIX] In an automatic temperature control system differentially biased saturable reactors in cascade are used to provide variable on-off control. As shown, on saturable reactor 30 the bias windings 35, 36 are arranged to oppose the reactance windings 32, 33, whereby in the absence of a control signal the reactor saturates late in the applied voltage cycle. On saturable reactor 20 the bias windings 26, 27 assist the reactance windings 18, 19 to produce early saturation A sharp current rise in the load 11 (heating element) is ensured by positive feedback through windings 28, 29 assisting saturation. Arrival of a control pulse from reactor 30 later in the cycle (through windings 24, 25) desaturates the reactor to cut off the current pulse through the load. As the heater warms up the control signal from the thermocouple through coil 34 opposes the bias on reactor 30 so that it saturates earlier in the applied voltage cycle and thus causes earlier desaturation of the reactor 20, i.e. reduces the time for which the current passes through the heater in each cycle.

[Class 135] A rotary plug cock has its conical plug 5 maintained in seated position only by the action of a spring 8 between the plug and an axially slidable operating rod 6 mounted therein, and by the engagement of a radial pin 9 on the rod 6 with the wall of a notched slot 10, 11. A slot 9<1> in the plug 5 allows the rod 6 to slide outwardly so that the pin 9 is engaged in the notch 11 of the slot 10 in the closed position of the plug. The slot 9<1> and the pin 9 prevent relative rotation between the plug and the rod 6. In Fig. 3, the end wall of the notch is formed by the end of a screw 22 threaded in an ear 20 on the casing, the removal of which screw enabling the pin 9 to pass through a slot 23 so that the cock can be dismantled.
