IPC: H01M50/103
Filed: 1955-02-09
Abstract: 803,385. Batteries. PERTRIX-UNION G.m.b.H. Feb. 9, 1955 [Feb. 9, 1954], No. 3864/55. Class 53. The casing of a cell consists of two plastic shells 1, 2 fitting one within the other and which are formed and assembled at a temperature at which the material of the inner shell is hard and rigid and in a state of strain. The assembly is then heated to a higher temperature which releases the internal stresses and causes the edge of the inner shell to be urged outwardly into tight engagement with the outer shell. The inner shell may be made of cellulose acetate or polyvinyl chloride and. shaped by a cold drawing process which leaves the material in a state of strain. The cell shown in Fig. 3 comprises a depolarizer electrode 3 which projects through an opening in the shell 1, and a zinc electrode 4 above an opening in the shell 2. The electrodes are separated by an electrolyte carrier 5.

Title: Improved means for the production of water vapour or steam and for injecting or delivering the same into bakers' ovens, and other chambers or compartments
IPC: A21B1/08
Filed: 1937-02-10
Abstract: 470,961. Air moisteners for bakers' ovens &c. BONNER, F. H. Feb. 10, 1937, No. 3933. [Classes 51 (ii) and 55 (ii)] A moist or humid atmosphere is formed in bakers' ovens or other chambers by forcing a stream of hot air along a conduit 8 leading to the oven &c. and causing it to pass by or over the end of a tube 12, dipping into water in a container 10, so that water is drawn up by inductive action and is converted into steam or water vapour. As shown in connection with a baker's oven, hot air is drawn from the oven chamber through an inlet 6a and piping 5 by a motor-driven fan 2, and is returned through the conduit 8 and nozzle 9a. A float member 13 is associated with the water container 10 and carries a rubber-faced disc 15 which closes the port 18 when the water falls to a predetermined level, and so cuts off the supply. The duration of steam supply may be fixed by filling predetermined quantities of water into the container, or the disc 15 may be adjustable on a graduated float rod. When two or more chambers are to be supplied with steam, a single fan may deliver air to separate atomizers, one for each chamber, and the circulating system may include a valve for admitting cold air to vary the humidity as desired. A byepass leading to atmosphere may also be provided so that the fan can be used for extracting steam-laden air from the compartments. Alternatively, a single fan and atomizer unit may be connected with a number of chambers through multiple-way valves so that hot air can be drawn from and returned to any chamber.

Title: Improvements in or relating to arrangements for limiting overload currents in direct-current and alternating-current supply systems
IPC: H01H9/10
Filed: 1954-02-10
Abstract: 748,532. Protective cut-out arrangements; electrically-released switches. F. K. G. F. KESSELRING GERATEBAU AKT.- GES. Feb. 10, 1954 [Feb. 10, 1953], No. 3950/54. Class 38(5) An overload protection arrangement enabling the use of current-limiting fuses of relatively-low current-rating, comprises a pair of fuses 3, 4 rated for one-tenth of the normal current, the end caps 5, 6 of which are connected to metal members 8, 9 constituting the fixed contacts of a shunt switch. The centre cap 7 of the fuses is connected at 17 to a movable bridging contact 16 which is normally held closed by a wire 27 having balls 28, 29 engaged in slits 30, 31 of, respectively, the contact 16 and an upwardly-biased leaf spring 19. The wire 27 also passes over an adjustable roller 20 on an arm 21 and is engaged by a knife-edged contact 33 on a leaf spring 32 which is connected by a lead 25 to a terminal 10 conductively connected to end cap 5 by a conductor 15 carrying iron laminations 14. Normally the switch 8, 16, 9 caries most of the current, but when a short-circuit occurs. the inductive effect of parts 14, 15 sends a current through spring 32 and wire 27 sufficient to fuse the latter and release the spring 19 which rapidly opens the switch and diverts the current through the fuse to rupture it. The time between the onset of the overload and the opening of the switch must not exceed 0.5 milliseconds, and the voltage across the fuse must not exceed 15 volts and must be at every instant less than the breakdown voltage of the switch. The latter may be oil or gas-immersed or of the vacuum type. In Fig. 2 a condenser 41, kept constantly charged by an autotransformer 44, discharges across electrodes 47 to fuse the wire 48 when a spark gap 46 is broken down by the discharge of a spark gap 40 energized by a line current transformer 62. In another embodiment (Fig. 3, not shown) the movable bridging contact forms the armature of a magnet which is energized either directly by the line current, or by discharge of a condenser as in Fig. 2. The armature is held in its attracted position by the flux of a permanent magnet forming part of the magnetic circuit, against the action of a bowed leaf spring. The Specification refers also to the automatic connection of a fresh device in circuit after one has operated.

Abstract: 1,128,497. Fluid pulse generators. BENDIX CORP. Jan. 27, 1967 [Feb. 4, 1966], No. 4100/67. Heading G3H. A fluid pulse generator has an input channel 23, output legs 24, 28, a control passage 32 arranged to receive fluid pulses and a chamber 36 provided with a plunger 38 by means of which the volume of the chamber can be adjusted to vary the time during which the fluid is directed to leg 28. In operation, with pressure P1 only applied to the device, fluid issuing from outlet 23 will aspirate chamber 36 thereby drawing the fluid into leg 28 which is connected to exhaust. On receipt of a pulse P2 in passage 32, pressure rises in chamber 36 so switching the fluid into leg 24 where it remains until sufficient vacuum has been re-established in chamber 36 to switch the fluid back into leg 28. The device is described in connection with variation of pulse width Figs. 2, 3 (not shown). In another embodiment Figs. 4, 5 (not shown) three fluid devices are connected in cascade, the last two being similar to that described above, to control the time interval between the application of a pulse to the first device and the receipt of a pulse from the last device by varying the volume of chamber 36 of the second device. Also the pulse width may be varied by adjustment of the chamber of the last device. In a further embodiment Figs. 7, 8 (not shown) a pair of devices are connected in series to produce an output pulse of predetermined duration. Fig. 6 (not shown) illustrates a device in which one of the corners (51) of channel 23 is rounded to bias the fluid into the adjacent leg and Fig. 7 (also not shown) illustrates an arrangement in which fluid is biased into one leg by removing the vortex forming part of the adhesion wall of the other leg.

Abstract: 1,159,902. Control systems for photo-flash apparatus. TOKYO SHIBAURA ELECTRIC CO. Ltd. 30 Jan., 1968 [31 Jan., 1967 (2)], No. 4694/68. Heading H2H. Photographic apparatus includes a photoflash device comprising a plurality of lamps L1-L4 of the type which provide a single operation only, the lamps being successively energized from a capacitor C when the synchronizing contact S of the camera is closed, the capacitor being charged from a D.C. source B between the operations of the contact S. The lamps are connected in parallel with each other and are fed by way of a resistor unit D. In operation, the capacitor C charges and, when the switch S is closed on making an exposure, discharges into the parallel arrangement of lamps. Most of the discharge current flows through the lamp L1 to ignite this lamp, the portions of the current flowing in the lamps L2-L4 being insufficient to ignite these lamps. After ignition the lamp L1 forms an open circuit, such that closure of the switch S on a further exposure again discharges the capacitor C into the parallel lamp circuit. In this instance the lamp L2 receives the greater part of the discharge current, thus this lamp is ignited, the lamps L3, L4 remaining unignited. The next closure of switch S ignites lamp L3 and so on. The resistors may be individually in series with the lamps or a combination of successively in series as in Fig. 1 and individually in series. Each of the arrangements may include transistors either successively or individually in series with the lamps or both. Alternatively, thyristors may be used.
