Title: Process and apparatus for making rolls, and the like
IPC: A21C5/08
Filed: 1924-11-27
Abstract: 235,131. Hus, B. June 6, 1924, [Convention date]. Bread etc.; proving-appliances; setting-appliances.-In the making of rolls, and the like, balls of dough from the dividing and balling machine are arranged in rows in grooved proving trays which are stacked in a pile and are then restacked in the reverse order, the balls, after greasing, being bashed in the trays by a press and then transferred, by inversion, to empty trays for a second proof and from thence, by inversion, to a peel plate by which they are inserted in the oven. A rotatable frame, Fig. 6, has a slidable nest of shoots 16 the openings at one end corresponding with the position of the dough lumps on the plate 26 of the balling-machine which is inserted in the frame. The plate 26 is inserted, the nest of shoots is lowered to envelope the balls and the frame is inverted, as shown in Fig. 6, whereby the balls fall through the shoots and drop into the grooves of the proving tray 4. Guide bars 17 are provided with pin holes 29, 30 whereby the shoots and the sliding tray carrier may be locked during inversion. The shoots 16 are extended slightly to project into the grooves of the proving tray. The lumps are greased by an oiled roller 51, Fig. 17, supported by U-shaped members 52 and the handle 53 over a tank 50. The balls are bashed by a press 35, Fig. 8, which is positioned over each tray, the press, which may be pedaloperated, consisting of a frame 36 and a spring- returned sliding member 38 having bashing wedges 40 which project through a cover plate 41. Fig. 14 shows the peel plate 48 positioned over the secondary proof tray 45 prior to inversion. The articles are, after baking, scooped out on the peel and transferred to the packing position. The Specification as open to inspection under Sect. 91 (3) (a) states also that the invention is applicable to the making of rusks, a baking plate being then used instead of the proving tray. This subjent-matter does not appear in the Specification as accepted.

Title: Improvements in the recovery of adiponitrile and in apparatus therefor
Filed: 1950-11-22
Abstract: Adiponitrile is recovered from the pasty mixture obtained by the reaction of a 1 : 4-dihalogenobutane with excess alkali or alkaline earth metal cyanide by introducing the pasty mixture under reduced pressure into an apparatus fitted with stirring blades or a screw conveyer and heated externally and/or by internally disposed heating plates to temperatures exceeding the boiling-point of the adiponitrile so that the latter distils over and a dry residue of salts remains.  Three forms of apparatus are illustrated (not shown), wherein is treated the pasty mixture obtained by reacting 1 : 4-dichlorobutane with excess sodium cyanide and containing adiponitrile, sodium chloride and the excess sodium cyanide.  In each case, the pasty mixture is continuously propelled into the reactor where it is heated under reduced pressure at 260 DEG  C. whereupon the nitrile distils off and a dry residue of salts is continuously removed.  One reactor is externally heated and has a vertically mounted spiral blade stirrer and a bottom removal point for withdrawal of the salts; another externally heated reactor is in the form of a horizontal tube with a screw conveyer along its length; the third reactor has several steam-heated plates arranged one above the other, the pasty mixture being fed from the top and swept over the plates by means of stirring blades and holes are provided in the plates at different positions to allow the residual salts to fall to a bottom removal point.ALSO:Adiponitrile is recovered from the pasty mixture obtained by reacting a 1:4-dihalogene butane with excess of an alkali or alkaline earth metal cyanide by introducing the pasty mixture under reduced pressure into a vessel fitted with stirring blades or a screw conveyer and heated externally and/or by internally disposed heating plates to temperatures exceeding the boiling point of the adiponitrile so that the latter distils over and a dry residue remains.  The process described is continuous and provision is made for automatic removal of the dry salts from the reactor.  Three forms of suitable apparatus are illustrated (not shown).

Title: Apparatus for Generating Digital Data Signals
IPC: H03M11/20
Filed: 1968-06-17
Abstract: 1,183,428. Electric selective signalling. GENERAL ELECTRIC CO. 17 June, 1968 [25 Aug., 1967], No. 28719/68. Heading G4H. Switches associated with manually operable keys are coupled to an encoder to produce a set of electrical pulses indicative of the operated key and of duration independent of the period of switch closure, the pulses being received by a first storage register and passed from it to a second storage register, the latter being emptied at a frequency exceeding the sustained maximum manual frequency of key operation. Each switch, when closed by its associated key on a keyboard, discharges a respective capacitor to pulse a diode matrix (the encoder), the parallel output of which enters the first register which supplies the data in parallel to the second register from which it is shifted out serially to a memory common to a plurality of such keyboard units. The memory communicates in both directions, over a telephone line, with a data processing system, controls a printer, and via a common character generator provides alphanumeric video display signals to a CRT display associated with each keyboard unit. The keyboard units, with their displays, are selected in turn for emptying of their second registers and display, clock signals to control this emptying, and the loading of the second registers from the first when the former are empty but the latter are not, &c. being supplied with the video display signals. The keyboard units in this way can communicate with each other and with the data processing system. The capacitors mentioned are recharged when their respective switches close (on key release) and do this via a greater resistance than used for discharging, so that pulses from contact bounce are negligibly small.

Title: Improvements in closures for bottles or similar containers
IPC: B43L25/02
Filed: 1935-10-17
Abstract: 464,419. Dispensing liquids. TAISHOFF, J., and SUTTON, G. J. Oct. 17, 1935, No. 28725. [Class 102 (ii)] [Also in Group XV] Relates to apparatus for dispensing liquids of the type in which the depression of a diaphragm 53, placed over the mouth of a container 50, causes liquid to be discharged through a tube 68 into a well 54 carried by the diaphragm. The invention consists in the operation of the diaphragm by the act of removing a closure 69. The diaphragm is secured to the container by means of a casing 57, which engages a flange 51 on the container, and the diaphragm is secured against a shoulder 55 on the well by means of a sleeve 56. The closure 69 has external lugs 70, which engage under a gapped flange 61 in the casing, and internal lugs 71, which engage helical grooves 63 on the exterior of the well 54. Rotation of the closure 69 to remove it causes depression of the diaphragm and of the well, and discharge of liquid into the latter. Rotation of the well is prevented by means of lugs 72 on a washer 59, which engage grooves 64 on the well. In a modification, the washer 59 is formed with a downwardly extending bevelled flange, which retains the diaphragm in its lower position, except when it is raised by the application of the closure 69. Specifications 434,658 and 434,690 are referred to.

Filed: 1929-09-23
Abstract: 336,080. Jackson, L. Mellersh-, (Siemens-Schuckertwerke Akt.-Ges.). Sept. 23, 1929. Mines, marine.-An arming device for submarine mines comprises a spring-loaded plate which carries a detonator and a locking device for the primer and is so constructed that when the plate is displaced by water pressure it brings the detonator into its live position and also causes the primer to fall into its live position. The primer 2 is normally supported in a guidetube 7 by a catch 11 on a rod 10. The rod is supported by a saucer-shaped plate 8 integral with a spring-urged cylinder 3 carrying the detonator 1. The plate 8 is supported by a hydrostatic diaphragm 4 which forms one side of a chamber 12. A small hole 13 in the said chamber is provided with a cap 14 normally closed by a stopper. The stopper has an opening device comprising levers 15, 16 and 17, the lever 15 being connected by a chain 20 to the mooring anchor. On the laying of the mine, the pull on the chain 20 opens the stopper and the water pressure acting on the diaphragm lifts the detonator and at the same time lifts the rod 10 to release the primer. The ignition of the mine takes place by the detonator receiving ignition by an electric current on the destruction of a lead cap or horn projecting from the mine. The hole 13 is made small in order to prevent undesired sudden movements of the detonator 1 when the mine is subjected to strong wave action.

Filed: 1971-06-21
Abstract: 1331383 Axial-flow and radial flow compressors BROWN BOVERI-SULZER TURBOMACHINERY Ltd 21 June 1971 [23 June 1970] 28918/71 Heading F1C In compressor control apparatus wherein an anti-surge regulator and a flow or pressure regulator are provided for operating a blow-off valve, a relay is provided for combining the output signals of the two regulators to provide a signal for operating the blow-off valve. A pressure regulator 10 comprises a bellows 12 subjected via a line 8 to the discharge pressure of an axial-flow or radial-flow compressor 1 and acting to regulate a leak-off valve 14 downstream of an adjustable restrictor 19 in an oil supply line 18, thereby varying the oil pressure applied via a line 17 to a servomotor 20 for adjusting the degree of opening of diffuser blades. The anti-surge regulator 11 comprises a bellows 30 subjected to the discharge pressure in the line 8 and a diaphragm 23 subjected via lines 24, 25 to the pressures in a flow measuring device 26 in the compressor inlet duct 3. When surge conditions are approached, a leak-off valve 29 downstream of a restrictor 34 in an oil supply line 33 is opened to drop the oil pressure applied to the left-hand side of a piston 42 in a relay 36. The piston 42 controls inlet and discharge valves 46, 47 in an oil supply line 44, the pressure intermediate these valves being applied to the right-hand side of the piston 42 whereby it is regulated to be equal to the pressure applied to the left-hand side and being applied via a line 43 to the servomotor 35 of a blow-off valve 7 in a blow-off duct 6 connected to the compressor discharge line 4 upstream of a non-return valve 5. A further piston 38 connected to the piston 42 is subjected at its lefthand side to the pressure in the outlet line 17 of the pressure regulator 10, the pressures at the two sides of the piston 38 being equalized via a duct 40 containing an adjustable throttle 41. In the event of a sudden change in the compressor discharge pressure and consequential sudden change in the pressure in the line 17, the resultant temporary inequality in the pressures at the two sides of the piston 38 produces a resultant temporary effect on the blow-off valve 7, this effect decreasing to zero in a time determined by the adjustable throttle 41. The control may be electric or pneumatic rather than hydraulic.

Filed: 1953-10-20
Abstract: 742,824. Thermionic valves. WESTERN ELECTRIC CO., Inc. Oct. 20, 1953,[out. 24, 1952], No. 28930/53. Class 39 (1). [Also in Group XL (c)] To compensate for the effect of the stray component of the output capacitance in reducing the " figure of merit " of a valve intended for use in broad band amplifiers, an impedancetransforming filter circuit consisting of lumped series inductances and shunt capacitances is interposed within the valve between the anode 61 and the output terminal 67. As shown, the filter circuit comprises an inductance coil 65 wound on an insulating rod 64 and surrounded by capacity discs 72 connected by a shell 71 forming part of the envelope of the valve. It is desirable that the values of capacitance should increase outwards and this is secured by increasing the thickness of successive discs 72; and that the inductances should decrease outwards, and this is secured by decreasing the spacing between successive discs 72 as shown, or by varying the winding pitch of coil 65. There is no separate D.C. connection to anode 61; it is capacitively connected to the inner end of coil 65 by the capacity between it and plate 63, and its D.C. voltage is obtained by connecting it to screen grid 56 by a resistance 62 formed as a coating on the inside of ceramic insulator 60, which supports the anode in correct spacing from the screen grid. Control grid 40 is supported on frame 41 connected to the input terminal 42. Cathode 37 is connected to disc 47 which forms with internal envelope flange 52 and mica dielectric 54 a by-pass condenser for the screen grid which is directly connected to envelope 35 by flange 57. An internal grid-leak resistor 49 is provided. The input and output terminals form the inner conductors of concentric line connectors 42, 43 and 67, 69 respectively. Specification 707,711 is referred to.
