Title: Improvements in the means for manufacturing bricks
IPC: B28B11/16
Filed: 1956-02-27
Abstract: 846,546. Cutting apparatus for extension brick machines. BENNETT, C. L. Feb. 22, 1957 [Feb. 27, 1956], No. 6064/56. Class 87 (2). A brick making machine in which lengths are cut from a moving column 1 of clay or other plastic material comprises a carriage 12 reciprocatable along the line of travel of the column and having mounted on it a target 9 movable between an operative position in which it is disposed in the path of the column so that the carriage 12 is moved in one direction at the same speed as the column and an inoperative position in which a length cut from the column can travel past it, a cutter 4 mounted on the carriage and movable through the column, two actuators mounted on the carriage, viz. a target actuator 15 for moving the target between its two positions and a cutter actuator 18 for moving the cutter 4 across the path of the column, and timing means controlling the operations of the two actuators. As soon as a cut is completed, a control device 'B' is operated to cause retraction of the actuator and raise the target 9 leaving a passage beneath it for the further progress of the length severed from the column. The carriage 12 is then returned by spring action to its initial position. The endless belt 7 carrying the cut length of material moves at a speed greater than that of the extruded column 1 thus leaving a gap into which the target 9 is lowered by operation of a control device 'C' when the cut length has progressed to a position beyond the target. The cut length advances until it reaches the target control device 35 when control device 'D' operates the pusher 25 which pushes the cut length sideways past the inclined cutter wires 39 where it is subdivided into brick lengths. Control device 'D' is arranged in association with a control device 'A', which operates the cutter 4, so as to prevent operation of the pusher 25 unless there is sufficient time available for its advance and retraction and to cause the target control device 35 to be raised if the column is not cut through, for example because of a broken cutter.

Title: Improvements in and relating to internal exhaust seals for electric lamps and similar devices
IPC: H01J9/40
Filed: 1946-02-27
Abstract: 608,676. Making electric incandescent lamps. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 27, 1946, No. 6071. Convention date, March 3, 1945. [Class 39(ii)] [Also in Groups XXXVI and XL(a)] A lamp has an exhaust tube 6 passing through the seal 3 into the interior of the envelope, its upper end 8 being sloped or notched. Adjacent to this is a disc-like closure member 7 preferably of sheet metal, e.g. chrome iron or " allegany 55," supported by heat-responsive means 9 secured to the lamp structure. In the preferential form described, this support consists of a wire or bimetallic strip bent into a coil welded to an inlead wire 2. After exhaustion and/or gas filling the parts 7, 9 are heated by any suitable means such as an induction coil 10 placed round the bulb 4; the part 9 is thus caused to expand and tend to uncoil, so that the disc 7 is pressed against the mouth 8 of the tube 6 fusing and sealing it. The invention may be applied to a lamp with a metal end wall, or to a long tubular lamp. Specifications 450,078, [Group XXXVI], 455,586, and 521,917, [Group XXXVI], are referred to.

Patent GB-512039-A (GB)
Title: Improvements in or relating to knitting machines with electrically controlled parts
IPC: D04B15/66
Filed: 1938-02-26
Abstract: 512,039. Stencil switches. ELITE-DIAMANTWERKE AKT.-GES. Feb. 26, 1938, No. 6103. Convention date, Feb. 27, 1937. [Class 38 (v)] [Also in Group VIII] During reversal of the carriage of a knitting- machine, electrical contact rods are selectively displaced by perforated cards so as to open certain contacts while leaving others closed. The contacts control the circuits of corresponding electro-magnets which actuate the parts of the knitting-machine. In Fig. 1, the carriage (not shown) has reached the end of its stroke, two contact rods 4, 4' have been pushed to the left by a card 2 carried on a horizontallyreciprocating prism 3, and blocking bars 12. have descended into recesses in the bars 4, 4<1> to hold the latter in position against springs 9. Contact knobs 6 on the rods 4, 4' have been pushed off conducting members 8 on to insulated members 7. From the position shown, the prism 3 recedes to the right and may then revolve to present a fresh card to the bars. The bars 12 are mounted on a member 13 which is raised and lowered by a rocking lever 14. When the member 13 is raised (a) a mercury switch 16 connected thereto is opened and thereby the contacts 8 are rendered dead so that no closing or opening sparks occur during movement of the contact bars and (b) the rods 4, 4<1> are pushed by springs 9 to the starting position. The cards may be perforated to control (a) the motion of the prism itself and after how many strokes it is to revolve by a certain number of cards and (b) means for effecting a reversal of current in the magnets to prevent permanent magnetization of the latter. The cards may be inadvertently perforated so as to allow simultaneous action by conflicting mechanisms; to obviate damage from this cause the feed to one group of magnets may pass through switches controlled by another group of magnets, the arrangement being that if both groups are fed the second mentioned-group either opens the switches and renders inactive the first group or diverts the current to actuate a signalling device &c. which may stop the machine. The current for actuating the magnets is derived from a low tension generator operated from the drive of the knitting-machine.

Title: Improvements in quick-acting switches for heavy current
IPC: H01H71/26
Filed: 1932-02-29
Abstract: 402,729. Automatic circuit-breakers. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.- (Assignees of Allgemeine Elektricitats-Ges.; 2, Friedrich Karl-Ufer, Berlin.) Feb. 29, 1932, No. 6108. Void [Abridged as open to inspection under Sect. 91 of the Acts, Feb. 28, 1932]. [Class 38 (v).] In a D.C. circuit-breaker of the type in which a conductor carrying the main current is adapted on overload to cause a diversion of flux from the armature to such an extent that the armature is released to interrupt the circuit, the coils of the holding electromagnet are disposed in groups between which is disposed the main current winding. As shown in Fig. 1, the magnetic circuit consists of an armature 1, intermediate members b and a yoke h separated from the members b by air gaps i. The energizing coils carried by the members b are divided into two groups f, g between which is disposed a transverse core k carrying a conductor l in parallel with a magnetic shunt m in the main circuit, excessive current in conductor l weakening the holding flux in armature a which is raised by its spring d to open the circuitbreaker c. The circuit-breaker may also be opened on a prolonged overload of insufficient value to release armature a by the operation of a time-lag relay o which opens the supply circuit of coils f, g. The circuits of coils f, g may be arranged as shown in Fig. 2 in which a resistance r is inserted in the coil circuits for maintaining the auxiliary armature in its attracted position by contacts h, q operated by the circuit breaker. Reclosure is effected by a switch o<1>. The sets of coils f, g may be disposed on the members b so that the main conductor l can be introduced between, thus permitting a narrow construction of circuitbreaker to be made. To equalise the current in the two groups of coils calibration resistances may be connected in parallel.

Title: Process for the preparation of diamidine derivatives
Filed: 1940-04-05
Abstract: 538,463. Amidines. MAY & BAKER, Ltd., EWINS, A. J., BARBER, H. J., NEWBERY, G., ASHLEY, J. N., and SELF, A. D. H. April 5, 1940, No. 6169. Addition to 507,565. [Class 2 (iii)] Diamidines are prepared from dicyano compounds of the formula NC.R X R.CN, where each R represents a benzene nucleus and X is a simple linkage or a group (CH 2 )n in which n is 1-12 and one or more of the CH 2  groups may be replaced by oxygen or sulphur or by the group NH. The method of preparing the diamidines consists in treating the dicyano compounds directly with an alkali metal amide and liberating the free diamidine from its alkali metal compound formed. The dicyano compound and alkali metal amide may be heated together alone or in the presence of solvents such as xylene, toluene, anisole, phenetole or diphenyl, or, the interaction may be effected at a low temperature in liquid ammonia. The subsequent liberation of the diamidine is effected by adding acid and precipitating with a base. Examples are given of the conversion of 4 : 4<SP>1</SP>-dicyano-1 : 5-diphenoxypentane and 4 : 4<SP>1</SP>-dicyano-α : γ-diphenoxy propane into the corresponding 4 : 4<SP>1</SP>-diamidino compounds.

Title: Record playback apparatus
Inventor: ELLARBY RICHARD ISAAC
IPC: G11B27/00
Filed: 1965-02-15
Abstract: 1,096,752. Recording and playback. TRAINING AIDS (BRISTOL) Ltd. May 13, 1966 [Feb. 15, 1965], No. 6379/65. Heading G5R. In an arrangement for playing back sets of information signals arranged in a predetermined sequence on a medium such as magnetic tape, and which may correspond to sound and/or vision containing information or instructions for use by operators who carry out the instructions or by students who absorb the information, or to sets of instructions for carrying out a test procedure, the information is arranged in main and subsidiary sets in a first signal channel. Control signals are recorded in a second channel to identify the main sets and in a third channel to identify and start the subsidiary sets. Further control signals in a fourth channel are arranged in a coded sequence and related to both main and subsidiary sets of information. A logical control system is arranged to be operated from external switches to actuate the tape drive mechanism to present a particular set of information signals to the signal pick up heads and to arrange that the second channel is read when the next main set is reached and the third channel is read when the next subsidiary set is reached, to indicate the movement of the record to the control arrangements. When a particular information set is being played back, the fourth channel is read and the coded signals it contains are stored; to provide stop signals when the end of the particular set is reached. The external actuating switches enable the instructions YES, NO and REPEAT to be given to the control logic. After a main information set has been played, the tape stops in response to the coded control signals picked up from the fourth track. If the YES switch is next operated to show, for example, that a test has been successfully carried out, the tape is fast wound forward to the next main set and is stopped there by a signal picked up from the second track and then played at normal speed. If the NO switch is operated an appropriate subsidiary set of information which may be a fault finding sub-routine is selected in response to the coded signal by the control logic and played, and so on. The system may be used to control a projector drive in synchronism with sound information signals. The apparatus may incorporate facilities to enable particular sets of information to be searched for and played back, the information being located by coded addresses in the second track which are compared with a required address set up by selector switches. A system of interlocks prevents external signals reaching the logic circuits while the tape is moving.
