Title: Improvements in and relating to electric relays
IPC: G05B11/01
Filed: 1933-06-15
Abstract: 421,184. Electromagnetic switches. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, TAYLOR, H. W., Highfield, Bilton Road, Rugby, and STEWART, C., 49, Mansfield Road, Luton, Bedfordshire. June 15, 1933, No. 17110. [Class 38 (v)] An electric relay in which a floating contact member is moved by an electrical quantity to be regulated into engagement with a fixed contact, has an attachment secured to the movable relay element furnished with a thin strip of magnetic material which floats in a path parallel and in close proximity to a part of a magnetic circuit which is completed through a relatively narrow non-magnetic gap positioned at the end of the path of travel of the strip, whereby the floating contact is urged against the fixed contact only when at a predetermined short distance from the end of its travel. As shown the contact B is normally maintained floating between fixed contacts C<1>, C<2> by a solenoid having a core mounted on a beam pivoted at D and acted upon by spring F. Secured to the beam below its pivot i, is a non-magnetic pendulum-like member G carrying a thin strip of magnetic-material H. Normally the strip H moves between the two narrow non-magnetic gaps LL of an auxiliary electromagnet in a path a short distance above the magnetic member between these gaps but as the contact B approaches one or other of the fixed contacts C<1>, C2 the strip H is attracted towards one of the gaps L. Thus contact is firmly established and maintained. The closure of the contact may be made to control, through an auxiliary relay, the electrical quantity to be regulated, so that the moving contact is subsequently moved away from the fixed contact it has engaged and immediately returns to its floating state. A permanent magnet with a similar arrangement of its magnetic circuit, may replace the auxiliary electromagnet. The magnetic strip may be replaced by two strips arranged to move in paths a short distance from the side faces of the magnetic members adjacent the air gaps or by magnetic members working on three sides of these members.

Title: Ammunition projectiles for small calibre rifles and method of making same
IPC: F42B12/78
Filed: 1926-07-09
Abstract: 278,448. Olin, J. M., and Schuricht, A. G. July 9, 1926. Cased forms; projectiles.-Projectiles for small calibre rifles are made by depositing a non- abrasive metal, such as copper, on a lead slug by electro-deposition, spraying, dipping, or like process, and working and forming the plated slug at the driving part so as to condense the plating and conform the driving part diametrically to the rifling. A lead slug which is preferably shaped in a swaging die, Fig. 4, comprising dies 2, 3, 5 and an ejector 4, is plated with a coating, and the plated slug is then swaged by means of dies and formers so as to secure the desired conformation and treatment of the plating. A vent is provided in the die 2 to receive excess metal. The plated slug, prior to swaging, may be of greater or less diameter and length than the finished projectile in order that the swaging operation may cause compression of the plating 9, Fig. 3, particularly at the driving part 8. The slugs may be cut from a plated wire, which has been previously worked; and such slugs are swaged to correct shape, the pressing operation causing the lead core to project to form a nose 23, Fig. 14. A plated wire 20 may be severed into slugs by means of rotating cutters 31, Fig. 16, adapted to turn the plating over the ends of the slugs. One end of a slug may be cut off square, in order to form a projectile having a plated nose, and a lead base. In the case of applying the coating by spraying, the plating may be finely divided metal carried by a suitable vehicle, such as varnish.

Title: Method and apparatus for shearing glass
IPC: C03B7/088
Filed: 1960-05-17
Abstract: 891,822. Glass manufacture. PITTSBURGH PLATE GLASS CO. May 17, 1960 [May 26, 1959], No. 17360/60. Class 56. To control the position of the shear marks on a gob of glass in the shearing of a downwardly directed stream of glass issuing from an orifice, the rate of flow across the cross-section of the orifice is caused to vary in an asymmetrical pattern whereby there is curling of the unsheared glass adjacent the orifice between shearings. An orifice tube extension has a discharge end angularly arranged relative to the longitudinal axis and the extension may be vertical as shown or angled so that the end is horizontal. As shown in Figs 1, 3, 5, the glass from a tank 10 with discharge orifice 12 flows through an extension 24 with its end 26 angled between 15 and 45 degrees to the longitudinal axis. The glass is cut by shear blades 20, 22 to fall on to a mould 14, leaving a shear mark 28. The molten glass then flows outwardly as in Fig. 3 so that the shear mark 28 moves to one side and a gob 30 when cut off is given a kick to the side by the shear blades 20, 22 to fall into the mould 14 with both shear marks 28, 28<SP>1</SP> upwardly disposed so as to lie at the outer edges of a finished article after pressing. To give a spread gob of glass, particularly for making multi-focal lens, an extension 50, Fig. 9, has a cylindrical portion 52 for attachment to the tank furnace and an outwardly tapered portion 54 terminating in cutaway tapers 54<SP>1</SP>. As shown in Fig. 14, the gob with initial shear mark 56 is allowed to spread with the countersink 58 of a major element blank 60, the mark 56 moving to one side, the blades 20, 22 then cutting the gob at 56<SP>1</SP> adjacent the mark 56, subsequent spreading leaving both shear marks 56, 56<SP>1</SP> upwardly disposed and above that part required to fill the countersink 58. The orifice extensions 24, 50 are preferably made of platinum.

Title: Improvements in or relating to alkyldichlorobenzoic acids and their use as herbicides
Inventor: KLEIN DAVID XAVIER
IPC: C07C63/70
Filed: 1959-05-22
Abstract: The invention comprises 2,3-dichloro-6-methylbenzoic acid and its salts and a mixture of methyldichlorobenzoic acids resulting from the conversion of one methyl group of dichloro-o-xylene to a carboxyl group.  The compounds may be prepared by ring-chlorinating o-xylene, side-chain chlorinating the resulting isomeric mixture of dichloro-o-xylenes to give a mixture of methyldichlorobenzyl chloride isomers, esterifying the chloride with an alkali metal salt of a saturated monocarboxylic acid e.g. formic acid, to give a mixture of methyldichlorobenzyl esters of the acid and oxidising the ester e.g. with nitric acid, to give the desired mixture of acids.  The 2,3-dichloro-6-methyl isomer may be separated from the mixture by selective esterification, followed by hydrolysis, leaving a residue containing the 2-methyl-3,6-dichloro, 2-methyl-3,4-dichloro and 2-methyl-4,5-dichloro isomers.  Alkyldichlorobenzoic acids of the formula <FORM:0877067/IV (b)/1> where one of R and R1 is a chlorine atom and the other is an alkyl group containing up to 4 carbon atoms, and their salts, amides and aliphatic monohydric alcohol esters, which may be used in herbicidal compositions, are mentioned.  The acids may be prepared by oxidising a bromodichlorotoluene to the benzoic acid and then replacing the bromine atom by an alkyl group according to the Fittig reaction or by subjecting a bromodichloroalkylbenzene to a Grignard reaction.ALSO:An herbicidal composition comprises an inert carrier and a herbicidally effective amount of an alkyldichlorobenzoic acid of the formula <FORM:0877067/VI/1> where one of R and R1 is a chlorine atom and the other is an alkyl group containing up to 4 carbon atoms, or a salt, amide or aliphatic monohydric alcohol ester of the acid.  The composition may take the form of a dust or powder, an aqueous dispersion, an oil-in-water emulsion or a solution in a ketone, alcohol, ether or hydrocarbon.  The composition preferably contains 2,3-dichloro-6-methyl benzoic acid and may contain other isomeric methyldichlorobenzoic acids.

Title: Electronic alarm timepieces
IPC: G04C3/14
Filed: 1977-04-27
Abstract: In apparatus for generating an alarm sound especially for small watches, all functions of the alarm are controlled by integrated circuitry which detects the state of a common connection point between a manually operable switch and a reference switch which is opened and closed by the timekeeping mechanism. There is thus only one external terminal led out from the integrated circuit for the purpose of connecting to the output side of the reference switch and the manually operable switch. The reduction in the number of terminals permits a corresponding reduction in the number of pins required and a reduction in the size of the circuit. The integrated control circuit includes flip-flops, gate circuits, inverters and a five minute counter.

Title: Improvements in or relating to telephone systems
Inventor: CORNER ARTHUR CHARLES
IPC: H04Q3/42
Filed: 1962-05-08
Abstract: 991,667. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. April 8, 1963 [May 8, 1962], No. 17646/62. Heading H4K. In an exchange which employs a marker for the setting up of connections, a subscriber may cause his incoming calls to be diverted to a predetermined substation by dialling a code number into the register. In one arrangement, Fig. 1, the line circuit ISLC of Specification 909,237 is modified by the addition of a relay TCD connected, instead of the permanent ground alarm lead PGA, on the directory side of the IDF. When the subscriber dials the prescribed code into the register, the connection is released, so that relay K falls back, but relays LR, P remain held as long as the line loop is maintained. Preferably the telephone instrument is provided with a locking key for this purpose. In consequence relay TCD energizes and transfers the marking lead MKR to the line circuit 2SLC of the substation to which calls are to be transferred. Alternatively the diversion may be effected on the equipment side of the IDF by additional contacts of relays P, K. In another arrangement, Fig. 2 (not shown), when the connection is released from the register, relay K holds over the loop and disconnects LR, thus effecting the transfer of the marking lead. The invention is particularly applicable to the so-called self-steering system described in Specification 890,235.
