Title: Improvements in and relating to automatic firearms
IPC: F41A19/30
Filed: 1934-11-22
Abstract: 442,044. Automatic guns. STACK, I. I., 18, Vartavagen, and LINDFORS, A. T., 5, Grevturegatan, both in Stockholm. Nov. 22, 1934, No. 33614. Convention date, Nov. 22, 1933. [Class 119] Relates to gas-operated guns having a tilting breech-block 1 connected to the gas-piston 17 by a link 6 pivoted to the breech-block and the piston. According to the invention, the link is extended beyond the pivot 13 on the breechblock to form a cam-lever which tilts the breech-block away from its locking abutment 2<1> on the breech casing 2 and then engages by its cam surface 14 an abutment on the casing to retract the breech-block and unseat the cartridge case without shock. In the form shown in Fig. 1, the cam surface 14 bears against a crosspiece 15 bridging the upper and lower parts of the breech casing, which crosspiece is loosely mounted on the breech-block and moves rearwardly therewith. When the parts have returned to locked position, the link 6 engages the rear end of the firing pin 19 and moves the pin forward for firing. In the modification shown in Fig. 6, the link 6 occupies a raised position and its cam surface 14 engages an abutment 55 on the upper part of the breech casing. The firing pin is operated by a spring- pressed head 61 connected to the gas piston 17. The Specification as open to inspection under Sect. 91 comprises also a statement in general terms that the invention may be applied to guns having a sliding barrel and to guns operated by inertia weights. To facilitate manufacture, the breech casing 2 is made of steel tubing united by a front stirrup member x to the tube forming the gas cylinder. A rear stirrup member y has a detachable bolt for hingeing the stock, to permit of ready withdrawal of the parts from the rear. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to reciprocating engines
IPC: F02B75/30
Filed: 1935-12-05
Abstract: 466,796. Combustion-product engines. KITCHEN, J. G. A. Dec. 5, 1935, No. 33680. [Class 7 (i)] [Also in Group XXVI] The working chamber of a fluid-pressure engine comprises a series of at least three telescopically - arranged non - contacting tubular elements carried by the stationary head and the piston element of the engine. Pressure fluid is supplied centrally to the stationary head and expands sinuously through the annular passages and exhausts from the outer element. Some of the elements are always intercalated. They may be made of steel of about À022 inch gauge. The cylinder head 10 and the piston head 11, Fig. 1, carry concentric tubular elements 12, 13. The head 11 is guided by a rod 16 and a guide 17. The inner faces of the cylinder head and the piston head may be shaped so as to obtain the maximum effect by reaction. The elements may differ in length. The crank-shaft may be situated at one side of the cylinder but within its length. A compound engine of the twostroke type with a low-pressure cylinder constructed of concentric elements is described. A six-cylinder combustion-product engine with two rows of cylinders is shown in Figs. 5, 7 and 8. The piston heads 11 are connected by arms 35 to guiding cylinders 36 provided with ball bearings which operate a three-throw crankshaft. The gaseous fuel is supplied by a blower 39 to combustion heads 40, and the combustion products are passed by pipes 41 to the working chambers. An inlet 43 leads to the innermost tubular elements 12. Cam-operated inlet valves 15 are provided. An engine is also described having two sets of six radial cylinders. The fuel-supply pipes 41 lead into annular grooves in a chest containing a ported rotary valve fixed to the crank-shaft.

Title: Improvements relating to the separation of organic liquid from mixtures containing same
IPC: B01D3/36
Filed: 1928-11-19
Abstract: 305,528. Soc. Anon. des Distilleries des Deux-SÞvres. Feb. 6, 1928, [Convention date]. Acids, distilling; alcoholic liquids, distilling; distilling processes. - In separating by distillation organic liquids contained in aqueous mixtures consisting of a liquid or mixture of liquids B, miscible or not with water, but more volatile than A, the mixture of A and B is preliminarily dehydrated in a continuous manner in a dehydration column by the ordinary azeotropic method. To separate isobutyl alcohol from its mixture with isoamyl alcohol and water, as contained in fusel oil obtained as a residue in alcohol distillation, the mixture is fed from a vessel 7 into a heated column 1 previously charged with benzene; the water and benzene vapour pass from the top of the column 1 to a condenser 8 and decanting vessel 9, whence the aqueous layer is rejected and the benzene layer returned to the column 1 and the alcohols descend to the base of the column and are there run off and separated by ordinary distillation in a column 5. When the method is applied to the separation of ethylene glycol chlorhydrin from a mixture of water and cyclohexanol, cyclohexanol itself replaces the benzene of the earlier example. The method is also applicable to the separation of acetic acid from a mixture of water and cyclohexyl acetate, ethyl acetate being used as the water carrier. The operations may be effected at other than atmospheric pressure and the vapours of the liquid B issuing from the column 5 may be used to heat wholly or partially the dehydrating column 1. Specifications '296,974 and 300,246 are referred to.
Patent GB-782618-A (GB)
Title: Improvements in and relating to electronic calculating and similar machines
IPC: G06F9/26
Filed: 1955-11-25
Abstract: 782,618. Digital electric calculating-apparatus. MAX-PLANCK-GES. ZUR FORDERUNG DER WISSENSCHAFTEN, E. V. Nov. 25, 1955 [Nov. 29, 1954], No. 33881/55. Class 106 (1). An arrangement for controlling a calculating machine or the like includes a number of chains of windings associated with saturable, bi-stable magnetic cores, each chain corresponding with a main command and the individual cores serving to initiate subcommands in the required sequence. The embodiment is described in relation to a paralleltype office machine performing operations such as multiplication by repeated addition. Instead of using a control commutator consisting of hard - valve counting rings, chains of saturable bi-stable magnetic cores are employed. Each main command is deciphered in a tree circuit leading to selection of one of a plurality of chains such as K1 ... Kn, Fig. 4, by reversal of the first core K1. Alternate cores are connected by windings S1, S3 ... &c., and S2, S4 ... &c., to lines I and II, respectively, which receive, alternately, amplified stepping pulses applied at terminals 15 and 16. The same stepping pulses are applied through cathodefollowers 11 and 12 to alternate groups of transfer windings E1, E3 ... &c., E2, E4 ... &c., preventing any spurious transfers in a rearward direction and ensuring that only one core in the chain is in the reversed state at any time. The output signals for controlling the calculating machine appear on terminals A1 ... An in succession. Branching chains K<SP>1</SP>3, K<SP>1</SP>4, K<SP>1</SP>5, Fig. 6, may be employed, the path to be taken by the reversal condition being determined by the presence of an appropriate signal on one of the lines L 1 or L<SP>1</SP>1. Such a signal is applied via a cathode follower as in Fig. 4. Further branching from the secondary chain is possible, and various arrangements for linking back to the main chain (as in Fig. 6), forming a closed ring (shown dotted in Fig. 4), skipping several cores, if desired, &c. are described. Deciphering of the main command signal may be accomplished by a matrix of cores (Fig. 10, not shown) or a tree arrangement, Fig. 11. A three-binary-digit command controls the passage of a reversal condition from the core Ka to one of the cores Kd1 ... Kd8; the first digit, signalled on line L2 or line L<SP>1</SP>2, determines whether current is passed through winding Eb1 or Eb2, in the second column; the second digit, signalled on L1 or L<SP>1</SP>1, selects a core in the third column, and the third digit, signalled on L2 or L<SP>1</SP>2 again, determines which core Kd1 ... Kd8, forming the first core of a main command chain, is to be reversed. The Specification indicates how the invention can be applied to series-type computers &c.

Abstract: 507,883. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON, THUNELL, K. H., VIGREN, S. D., and CLAESSON, P. H. E. Nov. 22, 1938, No. 33933. [Class 40 (iv)] In an arrangement for direct current impulsing over inductively coupled telephone junctions, the secondary of a separate transformer A1, the primary of which is connected to a condenser charged and discharged by the impulse relay, is connected in shunt to the line winding of the ordinary speech transformer. Received impulses are passed to a relay MR1 by a further transformer B1. The latter is so associated with the sending transformer A1, a choke coil D1 and an artificial line b1 that transmitted signals do not affect the receiving relay. The invention is shown applied to a phantom-circuit system, all three transmission channels having similar impulsing arrangements. The forward impulses may be selecting impulses and the backward ones signals indicating that the call is to be interrupted in. favour of a preferred call. The arrangement, which is symmetrical, allows both way operation over all the channels.

Title: Automatic fault location arrangement for electric or elec- ronic control systems
IPC: G01R31/317
Filed: 1972-07-24
Abstract: 1398874 Monitoring voltage levels at a plurality of points KOMBINAT UMFORMTECHNIK ERFURT VEB 24 July 1972 34494/72 Heading G1U [Also in Division H2] The voltages existing at a plurality of points 1,2,..., n, Fig. 2, are monitored to determine whether any rises above a pre-set threshold level, such rises being associated with faults, by associating a bi-stable threshold device with each point via appropriate coupling circuits 8,9, by detecting, by means of a gate 7, when any one, or more, bi-stable devices becomes set in its 'one' state - which corresponds to the existence of a fault - and then, by means of a scanning circuit 12,14,15, sequentially connecting the bi-stable circuits, oneby-one, over contacts 13, to a further detector 16 so that the particular bi-stables which are set in their 'one' states can be identified. In operation the system is initially reset by depressing a key 10 which puts a bi-stable 11 into a state in which it resets all the threshold bi-stables 4 to 'zero'. If the points 1,2,..., n, are associated, as in the embodiment described, with a machine tool, then once the machine is switched on a contact 20 is closed. Monitoring of the points 1,2, ...,n, now proceeds and providing no fault occurs all the threshold bi-stables 4 remain in their 'zero' reset states and a lamp 6 is energized via a gate 5. When a fault occurs, it is detected by both gate 5, which deenergizes lamp 6, and gate 7 which reverses the state of bi-stable 11 thereby causing the scanning control unit 17 to connect the bi-stables 4 sequentially to the detector 16. When a bi-stable 4 registering a fault condition is found, the detector 16 causes further scanning to be inhibited until a "continue scan" device 18 is manually actuated. While scanning is inhibited the number of the  point at which it stopped is indicated on a device 3 so that the fault can either be repaired or its location noted, before scanning is restarted.

Title: Improvements in card feeding devices for card controlled machines
IPC: G06K13/07
Filed: 1954-11-29
Abstract: 753,206. Statistical apparatus. MAUL, M. Nov. 29, 1954 [Dec. 29, 1953; Sept. 30, I954], No. 34574/54. Class 106 (1). A card feeding device is characterized in that a rotating member is provided which projects into the card feeding path during part of its revolution and also moves in the card feeding path in the direction of card movement at a lower speed than that of the cards. The card feeding member is in the form of rotating star-shaped cam 12, Fig. 1, the noses of which project into the card feeding path. The cards are fed by rolls 11 under brushes b<SP>1</SP>-b<SP>6</SP> where they are arrested by one of the noses of the star-shaped cam. The second position of the feed-cam indicated by dotted lines is provided for the second deck of the card, the distance between these two positions amounting to the distance between decks on the card. When the analysis of the card is completed the stop releases the card to the sorting deflectors 19 which are actuated by magnets in accordance with the data sensed from the card. The drive of the feed cam 12 is effected through shaft 13 by means of a gear 16 which engages the central toothed wheel 17. The shaft 13 is mounted on arms 26 fast on shaft 18. The lever 27 is also fast on the shaft 18, Fig. 2. The feed cam 12 may be rocked manually about the toothed wheel 17 to one or other of the alternative positions by means of the lever 27. The dimensions of the gears 16 and 17 and the rocking angle of the arm 26 are determined so that the feed cam 12 is lagging for a predetermined angle in the position indicated in dotted lines corresponding to the lower deck. The amount of the angle of lag is determined by the deck distance and the supply speed imparted to the cards by the rollers 11. The drive is imparted from the motor through the worm shaft 21, worm wheels 22 and feed rollers 11. A pinion 23 is rigidly connected with the middle worm wheel 22 and drives the toothed wheel 24, hollow shaft 25, and gear 17. The drive of the controlling cams 29, 28 and 31 for the contacts n<SP>1</SP>, n<SP>2</SP> and n<SP>3</SP> is effected by the worm shaft 21 through the worm wheel 32. In Fig. 2 the cam contacts n<SP>1</SP>, n<SP>2</SP> and n3 are arranged one behind the other so that n<SP>1</SP> only can be seen. The cam contact n<SP>1</SP> controls the analysing brushes circuit for the upper deck, the cam contact n<SP>2</SP> controls the analysing brushes for the lower deck and the cam contact n3 interrupts the holding circuits of the deflector magnets after the card has passed the deflectors. The contact U is provided to change over from n<SP>1</SP> to n<SP>2</SP> on change of deck position of the rotating card stop.
