Abstract: 799,587. Cleaning, glass sheets, carriages. BENDIX AVIATION CORPORATION. Jan. 23, 1956, No. 2204/56. Class 138(1). In a machine for treating at least one face of an object (e.g. a sheet of glass or the top of a wheeled table used for supporting a sheet of glass during a polishing operation), by means of sonic or ultrasonic waves developed by an electromechanical vibrator, in a liquid contacting the face, the object is moved through the machine in a fixed path extending parallel to one dimension of the face, the vibrator has a working face vibrating in a direction normal to the path in closely spaced parallel relation with the face and means are provided for forcibly projecting liquid between the two faces without submergence of the object and the vibrator in the liquid. As shown in Figs. 1 and 2 the machine 12 comprises upper and lower electro-mechanical vibrators 13, 14, between which dirty glass sheets 11 are passed on a conveyer 10. Each vibrator 13 and 14 is formed by a plurality of vibrator units 16 disposed in three rows extending transversely of the conveyer, the units of adjacent rows being staggered relatively to each other. The faces 16d, Fig. 3, of the vibrator shoes 16c together constitute the working free of the vibrator 13 or 14. The units 16 of the vibrator 13 are detachably mounted in a grid 48 carried by cross beams 45, 46 in turn supported by screwed rods 42, Fig. 2, adjustably secured by nuts 44 in brackets 39, 40 and 41 carried by a main cross beam 35. The lower vibrator units 16 are also carried in a grid supported by cross beams 55, 56 supported by jacks 63 connecting brackets 60 on the beams 55, 56 with brackets 67 on tubular member 68, 69, Fig. 2, secured at their ends to plates 38 which also support the beam 35 through pillars 36, 37. The jacks can all be operated from one side of the machine, so as to adjust the space between the vibrators 13 and 14, through the medium of screws 64 and rods 65, 66, Fig. 1. Water is sprayed onto the top and bottom of the sheet 11 from tubes 18, 19, 20 and 21, Fig. 3, whilst cooling of the vibrators is effected with sprays 31, 32, 33 and 34 from tubes 27, 28, 29 and 30. Electrical energy is supplied to the vibrators 13, 14 through cables 72, 74, Fig. 2, from housings 70, 73 at the upper and lower ends of pillars 71. Wheeled tables, constituting carriages, which are used in grinding and polishing operations on the glass sheets have their tops cleaned by passing a continuous stream of tables under a hinged framework housing a vibrator, similar to the vibrator 13, the framework also having wheels at its end opposite to the hinge, for contacting the table tops, all as described with reference to Figs. 6 and 7 (not shown). The wheels of the tables engage rails running below the hinged framework. Specification 774,043 is referred to.

Title: Improvements in Means for Automatically Igniting the Time Fuses in Projectiles.
Inventor: NEALE JOHN
IPC: F42C14/02
Filed: 1916-02-18
Abstract: 124,507. Neale, J. Feb. 18, 1916. Projectile fuses.-Relites to automatic igniters for time-fuses of rifle grenades and the like. According to the invention, a frictional member is adapted to be moved by a spring circumferentially over a cylinder, so as to ignite a plug of priming composition within the cylinder, this action occurring when a detent is rendered inoperative by the discharge of the projectile. In the construction shown, a strip of fabric c coated with match composition is arranged within a groove in a cylinder a. One end of the strip is secured by an elastic band d to a fixed pin e, and the other end engages by means of a loop or the like with a pin f. Before the projectile is discharged, a safety-pin i is pulled out, and the pin f is connected to the rifle, for instance by a wire loop k fitting over the sight. On discharge, the pin f is automatically withdrawn, and the elastic d draws the fabric over a coated plug of composition, (not shown), leading to the fuse, which is thereby ignited. The fabric is held in contact with the plug by a spring h. Other releasing devices, adapted to operate when the projectile is discharged, may be used instead of the pin f.

Filed: 1961-01-23
Abstract: 982,088. Magnetic storage devices. PLESSEY CO. Ltd. Jan. 23, 1962 [Jan. 23, 1961], No. 2548/61. Heading H1T. [Also in Division H3] Data storage apparatus includes a magnetic core structure in two parts 1, 2, at least one of which has at least one aperture 3 traversed by an electrical conductor 4, the material around the apertures forming storage elements having two remanent flux states, the axes of the apertures lying parallel to the plane of two mutually contacting faces of parts 1, 2, and an interrogate conductor 7 arranged between the faces orthogonally to the axes of apertures 3, whereby an interrogate flux 8 can be set up, passing through both parts of the core. The direction of current in conductors 4 determines the binary digit stored (" 1 " at 5, " 0 " at 6). An interrogate flux 8 rotates the stored fluxes without destroying them, and the polarity of the voltages induced in sense conductors 9 indicates the stored digit. Part 1 is of ferrite material, part 2 may be of different material, not necessarily having a square hysteresis loop. In modifications (Figs. 2 and 3, not shown) apertures 3 are provided in both parts 1 and 2 (both of ferrite). In one case grooves 10 are provided in both parts for the interrogate conductor; in the other case the mating faces of the parts are L-shaped. In a further embodiment (Fig. 4, not shown), the contacting faces are not grooved, the interrogate and other conductors being printed on to the magnetic body. Printed return conductors are arranged around the edge of the body. The core parts may be made by pressing powdered ferrite with a binder. The two parts may be fired separately or in contact so that they fuse. The Provisional Specification states that a refractory wire coated with cellulosic material may be inserted before firing to form the interrogate conductor in the latter case.

Abstract: 915,069. Temperature alarms. ELECTRONIQUE APPLIQUEE. Jan. 23, 1961 [Jan. 28, 1960], No. 2582/61. Class 118. [Also in Group XXI] An alarm which operates when a predetermined temperature is reached includes a slab 3 of ceramic material, such as barium titanate, which releases a charge when heated above its Curie temperature due to the sudden loss of dielectric polarization which results. The slab 3 has electrodes e connected through leads f to a current-responsive device U which may be an alarm relay. To prevent false alarms from transient heat waves the housing 1 is designed to delay heating of the slab, and a capacitor 8 is connected in shunt with the slab to increase the time constant of the circuit. When the Curie temperature is exceeded the resulting current actuates the device U. A common device U may supervise several slabs 3 by providing individual switches 10 for each slab and closing the switches cyclically to connect them to the device. The capacitor 8 will in each case store the charge produced by the current from the slab until the relevant switch is closed.

Abstract: 655,937. Electric selective signalling. IPSOPHON PATENTGES. AKT.-GES. Jan. 28, 1947, No. 2655. Convention date, Jan. 29, 1946. [Class 40 (i)] [Also in Group XXXIX] A device such as a telephonograph operates in response to a train of speech impulses only if the impulses and the intervals between are of the prescribed length. Impulses from a subscriber at T29 as well as disturbing influences on the line L28 are amplified at V6 and energize a sensitive relay J1 which operates a relay VJ2 in parallel with a condenser KO10, only if the exciting impulse is long enough. Each operation and release of relay VJ2 discharges one of a pair of condensers KBI5, KH14 through the winding of a relay K3 while charging the other. If the impulses or intervals are too long, relay K3 falls back before the next condenser is discharged through its winding, but if relay K3 remains energized it operates the required device A12.

Title: Improvements in and relating to lubricating compositions
IPC: C10M105/52
Filed: 1938-01-27
Abstract: 510,173. Lubricating-compositions ; polymerizing hydrocarbons. ARNOLD, C. (Lubri- Zol Corporation). Jan. 27, 1938, No. 2674. [Class 91] [Also in Group IV] A process for preparing a composition for use in lubrication consists in halogenating a complex mixture of organic compounds of the types found in .petroleum oils and treating the resulting halogenated mixture with a Friedel Crafts agent under such conditions of concentration, amount of catalyst or temperature of reaction, that only the less stable halogenated compounds are modified. The process is suitable also for coal tar and wood distillates. The halogenated mixture treated with AlCl3, FeCl3 &c. forms a product containing substantial amounts of halogenated alkylated cyclic compounds and relatively stable halogenated aliphatic compounds. Amounts of 0.1 to 20 per cent. of the stabilized composition above may be added to mineral, animal or vegetable lubricating oils. A mutual solvent may also be added. The AlCl3 sludge or the other solids are separated from the products before such additon. The halogen used is preferably chlorine. Compositions as above have improved extreme pressure, cold test, and anti-sludge characteristics. In an example, 3 parts of AlCl3 are added to 400 parts of chlorinated paraffin wax containing 36.4 per cent. of Cl and the mixture heated to a temperature of 75‹C. for half an hour. The mixture was then cooled to room temperature, an equal amount of C6H6 added and the AlCl3 sludge removed by dilute HCl. The C6H6 was distilled off and the final product contained 32.0 per cent. of Cl.
