Title: Improvements in breech mechanisms for guns of small and medium calibres
IPC: F41A3/40
Filed: 1924-07-25
Abstract: 222,447. Schneider et Cie. Sept. 28, 1923, [Convention date]. Ordnance breech mechanism. - Relates to breech-locking devices for automatic or semiautomatic guns of the long-recoil type in which the locking block is released when the barrel separates from the breech-block at the end of recoil, the re-engagement of the locking block being effected after the breech-block has returned to the barrel. According to the invention a cvlindrical breech-block C is locked in closed position by two or more toothed jaws D which are hinged to the breech-block or gun tube and engage corresponding teeth on the gun tube or breech-block. The jaws are opened during run-out by cams formed on a breech-block carrier E which is held fast while the barrel returns, the return of the carrier by a spring H' cocked during recoil serving to close the jaws. In the form shown, the jaws D are hinged to the breechblock which has a limited sliding movement on the carrier E which slides in guides B<2> during recoil and compresses the spring H<1>. When the gun runs out the carrier is retained by a catch 1, the jaws are released by inclines e<1> on the carrier spigot E', and a spring-bolt c<2> retains the jaws in the position shown. On releasing the bolt I by hand or automatically, the carrier is returned by the spring H<1>. the jaws are freed by the engagement of the bolt c<2> with an incline A<3> on the gun, and the jaws are locked against the gun by the carrier spigot.

Title: Improved apparatus for indicating or measuring at a distance physical or chemical values
IPC: G01F1/38
Filed: 1923-07-11
Abstract: 223,284. Roucka, E. July 11, 1923. Flow meters, pressure-actuated.-In apparatus for indicating or measuring at a distance physical or chemical values such as the flow of fluid through a pipe or the composition of gases, having a system sensitive to the value to be measured and a second system sensitive to automatically regulated electrical energy and tending to balance the first system, both systems acting mechanically on a movable part which is depressed periodically by auxiliary power to affect the controller of a. servomotor, a deflection of the movable part when the balance is disturbed causes a proportional movement of the servomotor controller. Fig 1 shows apparatus for indicating and recording the flow of fluid through a pipe. Differences of pressure on each side of a nozzle 2 in a pipe 1 arising from variations of fluid flow affect. a diaphragm 6 which is connected to a lever 15 pivoted at 16 and carrying a flat spring 17. The spring 17 carries a knife-edge 18 which is depressed periodically by a plate 45, Fig. 2, operated through a plunger 46 by auxiliary power. When the pressure difference in the diaphragm chamber 5 varies, the knife-edge. 18 moves over one or other of the levers 19, 20 which are connected through arms 24, 23 to the controlling piston 27 of a servomotor 29. One of the levers 19, 20 is thus depressed by the action of the plate 45 depending upon the position of the knifeedge 18, and the piston 27 is moved to a position corresponding to the deflection of the knife-edge 18 to allow the working medium to enter the servomotor 29 and regulate the resistance 33, 34 through the medium of the piston 30. The resulting variation in current from the battery 35 causes the moving coil 8 of an electrodynamic device 9, 10 to restore the knife-edge 18 to its neutral position and in consequence to restore the controlling piston 27 and cut oft the working medium from the servomotor. The regulation of the resistance 33, 34 also produces an indication and record of the variation to be measured on the instruments 36, 37 respectively. A resistance 61 bridged across the resistance 33, 34. is provided in order that consideration may be taken of the pressure in the pipe 1 in measuring the flow of fluid. The resistance 61 is varied according to the pressure in the pipe 4 by a piston 57. Alternatively the resistance 61 may be varied by a thermometer, in which case the indications take into consideration the variations of temperature. In order to prevent over-regulation a, dash-pot 38, 39 is connected between the knife-edge and the servomotor. A weak spring 11<a> is introduced between the movable coil 8 and the diaphragm b so that only a part of the power developed by the electrodynamic device is transmitted to the diaphragm. In consequence of this, very small variations of physical or chemical values may be measured by means of a large electrical energy. Specification 222,950, [Class 69 (ii), Hydraulic presses &c.], is referred to.

Title: Improvements in and relating to the winding of bobbins, spools, cops and other packages of yarn, thread or other textile filament
IPC: B65H54/50
Filed: 1938-06-17
Abstract: 504,236. Winding yarns. REINERS, W., (trading as SCHLAFHORST & CO., W.). June 17, 1938, No. 18080. Convention date, July 1, 1937. [Class 120 (ii)] Filaments or yarns are cross wound on a package by feeding a filament to the package over a helically grooved or slotted traverse drum which drives the package and obliquely thereto with a slant in the direction of the traverse controlled by the groove or slot, the helical groove or slot extending in one direction only through the full length of the drum to give the filament the controlled traverse in one direction only and having at its ends, oppositely directed extensions one of which guides the arriving filament into the groove or slot and the other reverses the slant of the filament at the end filaments, comprises a number of shafts or lap rods rotatably mounted on a rotatable frame and coaxial therewith, a pair of rotatable concentric discs of which the upper disc of the controlled traverse; when conical packages are being wound the groove or slot traverses the filament from the major to the minor diameter of the package. As shown the filament is drawn from a spool 1 through a guide 5 to the traverse drum 7 and package 2, the spool and guide being laterally offset with respect to the central transverse plane of the drum and package so that the filament is fed with a slant in the direction of the traverse given by the groove 10 in the drum. The groove 10 has short oppositely inclined extensions 12, 13 at its ends and a widened part 16 adjacent the extension 12. At the end of its controlled traverse the filament is engaged by the extension 13, slips out of the groove, and slides along the drum towards a stop 8 which limits its uncontrolled traverse, the extension 12 then engaging the filament so that it slips into the part 16 of the groove and is traversed thereby. The pitch of the groove may decrease slightly in either direction and one or more guides may be arranged near the guide 5 to equalize the drag on the filament as it is traversed ; the drag or tension may be automatically regulated by a pivoted finger bearing against the filament between a pair of guides and actuated by worm gearing and links from the shaft of the drum. The drum 7 may be used for winding packages of two different tengths by forming a notch 21 at one side of the groove at a point where the traverse to give the reduced length of package is to be reversed, the depth of the groove at this point being reduced, so that the yarn will slip out, by pushing rod 23 through a hole in the drum to form a ramp at the shoulder 22 formed by the notch 21.

Title: Data processing read and hold facility
IPC: G06F9/46
Filed: 1975-05-01
Abstract: 1536853 Multiple access storage systems PLESSEY CO Ltd 8 April 1976 [1 May 1975] 18129/75 Heading G4A Each of a plurality of processing modules PM is connected to all storage modules SM of a common memory, and each storage module returns an address parity indication to an accessing processing module, the parity indication being inverted in response to a next succeeding write operation following a read-andhold operation. The arrangement allows a processing module to lock on to a particular storage module when it is required to read data from a particular location and subsequently to write at the same location. A store access demand accepted by the access module ACC of a storage module sets a toggle RAH to inhibit a parity inverter IPAR2 during the read operation of a read-and-hold command so that the true parity bit produced by an address parity generator PAR2 is returned to the processing module for comparison with the output from a local address parity generator PAR1. A subsequent write demand resets toggle RAH if not already reset by automatic time-out to cause the inverted address parity to be returned to the processing module requesting the access, this module having its parity inverter IPAR1 enabled by the write demand, and hence an equal comparison should again result. If some other processing module attempts to access a storage module in which a read-and-hold operation is in progress, inverted address parity is returned to that processing module which forces it into a recovery sequence, as would happen if the unequal comparison of address parities resulted from corruption of the address during transmission or if the read-and-hold mechanism fails. The processing modules may be microprogrammed processors of known type and may be connected to the storage modules by X and Y buses. The X bus has a set of 24 leads for addresses and write data, three control leads redundantly coded to protect against single bit errors and specifying the requested storage operation, an ODD/EVEN parity control lead and bus valid and timing leads. The Y bus has a set of 24 leads for read data, a read data parity lead, an accumulated parity lead for successive forward data and parity control leads in a single access, and valid cycle (demand accepted), peripheral register busy, peripheral status fault and timing leads. The processing modules may be connected to separate parts of a storage module access unit or a plurality of processing modules may share a common part of an access unit via a multiplexor.
