Title: Improvements in magnetic switches
IPC: H03M7/00
Filed: 1959-06-26
Abstract: 909,899. Circuits employing bi-stable magnetic elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 26, 1959 [June 30, 1958 (2)], No. 22083/59. Class 40 (9). In a magnetic switch comprising a number of cores, each with a single output winding and various input windings, a pulse is induced in one output winding in response to the selective energization of one half of the total number of input windings, these windings being so arranged that in a group of four cores the state of one core only is reversed by combined input energizations, while the remaining cores receive equal and opposite input energizations so that no spurious outputs are induced in the respective output windings. As shown in Fig. 1, magnetic cores are arranged in two groups 10-16 and 18-24 and are energized from input circuits by way of NPN transistors 18a, 18b-24a, 24b and input windings 26a, 26b- 32a, 32b arranged in pairs. Each winding of a pair such as 26a, 26b or 28a, 28b passes through the cores in the opposite sense to the other winding, and the four pairs of windings are so arranged that energization of one winding of each pair, e.g. 26a, 28b, 30a, 32b causes a " 1 " magnetizing state to be set up in a single core such as core 12 in one of the two groups. The other cores in the group each receive opposing and equalizing energizations so that no flux changes occur and no spurious outputs are induced in the respective output windings 34a-34d. The selected core is restored to state " O " by current applied by a transistor 39 to a winding 38. Opposing and equalizing energizations are also applied to all the cores of the second group, except for that core, e.g. core 20 which is the counterpart of the switched core 12. This core is driven from its remanent " O " state into saturation in the same sense and produces a small spurious pulse. An alternative arrangement is described, Fig. 4, in which groups of four cores such as 40-43 are arranged in a 4 x 4 matrix, each core being associated with column and row input windings, each set of windings being arranged as previously described. The column and row windings are selectively energized over transistors 56a-59b and 60a-63b respectively to cause coincidences switching of a single core, and the cores are normally biased well into the " O " saturation region by current in a winding 64. Due to the bias, automatic restoration of a selected core from state " 1 " to state "O" takes place when the input signals terminate. Rapid restoration of a switched core may also be effected by transferring the input signals to the other half of the windings.

Abstract: 783,533. Electric grills. PARNALL (YATE), Ltd. July 18, 1955 [July 29, 1954], No. No. 22185/54. Class 28 (1). [Also in Group XI] A grill has a sinuous electric heater 6 of the tubular sheathed type pivoted for rotation about horizontal trunnions 5 at its outwardly extending ends on or within a vertical support panel, e.g. the rear splash plate 1 of a cooker, and a dished reflector 8 has a peripheral wall 9 with slots 10 for pivoting the reflector on the trunnions 5, so that the grill and reflector may be turned down to a vertical position against the panel 1. The heater 6 is of flat rectangular shape, and current may be supplied thereto by spring clips on the trunnions 5, supported in forwardly extending hollow columns 3 on each side of the splash plate 1, which is recessed centrally at 2 to receive the grill and reflector. A spindle 11 extends across the reflector 8 at each side and each spindle supports a cheek plate 12, removably pivoted thereon, so that the cheek plates may be folded up within the reflector parallel with the heater or may be turned down to a vertical position. The cheek plates 12 are grooved to support a grill pan below the heater 6 and when turned down serve as brackets supporting the grill in a horizontal position. The grill is releasably locked in the horizontal or vertical position, and current is automatically cut off when the grill is turned down. The heater 6 may be supported in a rectangular frame, the longitudinal side members of which are apertured to receive the ends of loops of the heater. The cheek plates 12 are supported from the ends of the rectangular frame and may be apertured for rotatably supporting a spit extending between them. The spit is rotated by a clockwork or electric motor within a column 3.

Title: Improvements in or relating to hose pipe and end coupling nipples therefor
IPC: F16L33/213
Filed: 1934-07-31
Abstract: 428,745. Hose couplings. BOSTON WOVEN HOSE & RUBBER CO., 29, Hampshire Street, Cambridge, Massachusetts, U.S.A.-(Assignees of Knowland, T. M.) July 31, 1934, No. 22336. Convention date, Aug. 2, 1933. [Classes 99 (i) and 99 (ii)] A coupling nipple 10, preferably reinforced by a pair of annular ribs 12, is secured within the end of a hose after vulcanization thereof by expanding it over a section of its length, the hose end being provided with a confining binder 28 of steel wire which is applied before vulcanization. The hose is built-up on a mandril and preferably comprises a wire helix 40, a woundon layer 16 of rubber which also envelops the nipple 10, a layer 18 of rubberized textile fabric &c., and further rubber and fabric layers 20, 24 followed by the binding 28, which is located concentric with the nipple between its ribs 12, and an outer fabric layer 26. While still on the mandril the hose is vulcanized, whereupon the mandril is removed and the nipple then expanded by a tool 30 which is provided with rollers 34 and a locating flange 32 and is rotated by a tapered member 36, the latter serving also to force the rollers outwardly. The fabric layer 18 may be wound as shown so as to leave a pair of circumferential openings opposite to the ribs 12 which are adapted to be filled by the rubber layer 20, the latter thus contacting with the rubber layer 16 and forming dams to prevent longitudinal seepage of any liquid leaking through the said layer 16.

Title: Improvements in and relating to artificial arms
IPC: A61F2/58
Filed: 1919-09-12
Abstract: 139,120. Corley, Q. D. Sept. 12, 1919. Limbs, artificial.-Comprises means for locking elbow-joints in any desired position, and consists in the general arrangement of the mechanism employed, and also in the special form of notches or teeth used to effect the locking operation. The forearm carries two angle-iron side straps 6 having bifurcated ends formed by the securing of offset members 7 thereto. The bifurcated portions are enlarged to form heads, and receive toothed heads on the ends of upper arm straps 9. Pins passing through the bifurcated portions form pivotal connexions between the straps 6, 9. Spring plungers 3, supported on the horizontal flanges of the straps 6, normally engage the teeth on the straps 9 to lock the joint. The teeth are shaped as shown in Fig. 5, so that they are higher at one end than the other, which construction is stated to obviate the possibility of the plungers missing any of the notches when free to engage therewith. The initial movement of the operating-cord 23, in the process of bending the forearm, withdraws the plungers and unlocks the joint by means of the lever mechanism shown in inverted plan in Fig. 4. The cord is connected to an upstanding projection 26 of a lever 27 pivoted between two superposed plates 4. A projection 31 on the lever engages the hooked end of one plunger directly, while a cam 34 on the lever simultaneously operates the other plunger through the medium of a lever 33. A cuff 5 attached to the artificial hand may be fitted over the framing of the forearm, as shown.

Title: Improvements in or relating to production of l-glutamine
IPC: C07C233/46
Filed: 1955-08-05
Abstract: L-glutamine is prepared by contacting with a hydrogen halide under anhydrous conditions, a solution of the gamma-amide of N-carboallyloxy-L-glutamic acid or N-carboallyloxy-L-glutamic acid 2-substituted in the allyl group by an alkyl or phenyl group, or the ammonium salt thereof or a mixture of the gamma-amide and its ammonium salt.  The gamma-amide may be used in formic acid, acetic acid, propionic acid, nitromethane or dioxane solution. The hydrogen halide, e.g. the chloride or bromide may also be used in solution. The reaction may be effected at about 15 DEG -40 DEG  C. The product contains the glutamine in the form of its hydrogen halide and the product may be worked up by dissolving it in absolute methanol, adding aqueous ammonia to adjust the pH to about 5.5, adding acetone and then crystallizing out the L-glutamine.  The crude glutamine may be purified by dissolving it in a minimum amount of hot water, adding acetone and crystallizing at about 0 DEG  C.  The gamma-amides used as starting materials may be prepared from a gamma ester of L-glutamic acid, e.g. an aliphatic or phenyl ester, by treating the gamma-ester with allyl or a 2-alkyl or 2-phenyl-allyl chloroformate, suitably in the presence of magnesium oxide or hydroxide at about 0-55 DEG  C. and then treating the resulting N-carboallyloxy-L-glutamic acid ester, which may be isolated by a solvent-extraction method, with ammonia to form the required gamma-amide.  Amidation may be carried out with liquid, aqueous or alcoholic ammonia in an autoclave at various temperatures from room temperature up to about 65 DEG  C.  In an example, L-glutamic acid is esterified with methanol, the resulting methyl ester is reacted in an aqueous medium containing Mg(OH)2 with allyl chloroformate, the product is amidated with aqueous ammonia and the resulting mixture of N-carboallyloxy-L-glutamine and its ammonium salt is stripped under reduced pressure and then reacted with hydrogen bromide in glacial acetic acid solution and the reaction mixture is worked up to isolate the L-glutamine in crystalline form.  The gammaethyl, propyl, isopropyl and butyl ester of L-glutamic acid and methallyl chloroformate are other specified reagents.  These gamma esters are prepared by esterification of the acid with the alcohol. Specifications 752,889 and 786,226 are referred to.

Title: Improvements in electrical indicators and the like
IPC: G08B5/28
Filed: 1919-09-15
Abstract: 144,525. Wrighton, J. C., and Edison Swan Electric Co. Sept. 15, 1919. Falling-flap annunciators.-Relates to electric indicators of the type in which a falling-flap is released by the action of an electro-magnet. Figs. 3 and 4 are end and front elevations respectively of a single indicator. On closing the electric circuit, the armature 8 is attracted and comes into contact with the non-magnetic head 11 of a movable stop 12 which slides in holes in the bent portion 13 of the frame 1. The attraction of the armature forces the head 11 to the rear against the action of the flat spring 18, and the upper edge of the stop 12 is moved from under the projecting lug 19 on the drop 4, thus permitting the latter to fall. The trigger-shaped portion of the non- magnetic head 11 prevents contact between the armature and the pole-piece and so avoids " sticking " of the armature through residual magnetism. A replacement rod 20 is provided with pins 21 which project laterally from it beneath the edges of the drops 4 when lowered, for the purpose of returning the drops to the raised position when the rod is turned.
