Filed: 1965-02-17
Abstract: 1,136,403. Container closures. READS Ltd. 16 Feb., 1966 [17 Feb., 1965], No. 6794/65. Addition to 904,664. Heading B8T. A pressure-relieving closure cap 1 for a container such as a drum is moulded from a plastics material and has a central, axially directed spigot 7 providing a blind bore in the cap, a radial hole 9 in the side of the spigot normally being closed by a rubber &c. band 10 fitting tightly around the spigot. If excess pressure develops in the container, the rubber &c. band 10 is forced away from the hole 9 in the manner of a spring-biased pressure relief valve, to allow venting of gas. The spigot 7 is formed at the apex of an inwardly-directed cone-shaped centre portion of the cap 1, and is aligned with its blind end 8 directed towards the outside of the container. The depth of the cone-shaped centre portion of the cap 1 is greater than the length of the spigot 7, so that the blind end 8 of the latter lies inside a ring-shaped groove 11 in the top of the cap. A protecting disc 12 having gas escape holes 14 is snapped into the groove 11, to close the open end of the cone-shaped centre portion of the cap and cover the spigot 7. Screw threads 3 are formed around the inside of the cap skirt.

Title: Method of producing semi-conductor rectifiers
IPC: C23C10/18
Filed: 1958-03-04
Abstract: 854,596. Semi-conductor devices. BROWN, BOVERI & CIE A. G. March 4, 1958 [March 5, 1957], No. 6878/58. Class 37 An alloy-type PN junction rectifier is made by causing a donor (acceptor) doping material in the liquid state to flow from a container into a mould on the surface of a P(N) type semiconductor body, and afterwards heating the assembly to produce an alloy type PN junction. Any oxide formed on the doping material remains at the edge of the container while the material itself flows out into the mould. In the embodiment an N type germanium wafer 1 is enclosed in a chamber 8 in a two part graphite mould 3, 10, into the upper half of which fits a glass tube 7 containing a metered amount of indium 6. in the solid state. After scavenging with an inert gas the chamber is evacuated, the mould heated to a temperature above the melting point of indium but below the alloying temperature and the indium melted from the top downwards by one or more heater coils 9. When the melting is completed the indium flows suddenly into the mould, leaving any oxidic impurities on the walls of the tube. The alloy junction may be formed some time later in any known way but is preferably formed immediately by raising the moulds to the alloying temperature. As a result of the mould. configuration shown and the removal of oxide from the indium a flat PN junction free from voids is produced.

Title: Storage cell and memory incorporating such cells
IPC: H03K3/315
Filed: 1966-02-17
Abstract: 1,065,702. Semi-conductor data storage matrix. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 17, 1966 [April 19, 1965 (2)], No. 6937/66. Heading G4C. [Also in Division H3] The input of a bi-stable storage circuit is connected to the base of a transistor so as to be switched by base current which flows when a current is applied to the emitter and a pulse is applied to the collector to cause the transistor to saturate. The Figure shows a conventional cross-coupled bi-stable circuit Q4, Q5 for a storage matrix having a word driver line W and bit drive and read out lines A, B. If the circuit is in the state in which Q4 is conducting the base of a gating transistor Q2 is at - V volts whereas the base of Q3 is at earth potential. Accordingly when a word pulse cuts off driver transistor Q1 the current from R1 flows through Q3 to indicate in line B by a current pulse and in line A by the absence of a pulse, the state of the circuit. If, however, coincident with the pulse at W a negative pulse is applied at B, transistor Q3 will saturate and substantial emitter current will flow to the base of Q3 to render QS conducting and so change the state of the circuit. The original state will be similarly restored by coincident pulses at W and A instead of Q1 may be omitted if the word pulse W is applied at Ve (Fig. 5, not shown) and one of Q2, Q3 may be omitted if alternative reset arrangements are provided. In Fig. 6 (not shown) the bi-stable circuit is replaced by a tunnel diode (T), transistor Q2 having its base connected to the diode so that base current will change the state in one direction, the supply to the diode being derived from a line (c) to which reset pulses may be provided. The circuits may be arranged in a matrix (Fig. I, not shown) with word drivers (WD) connected to a line terminated in its characteristic impedance (Z) and the bit lines connected to bit drivers (BD) and sense amplifiers (SA).

Title: Improvements relating to grip devices for holding tickets, paper sheets, and the like
Inventor: WOOD LESLIE FURNEAUX
IPC: B42F15/06
Filed: 1951-03-22
Abstract: 714,421. Filing papers; sheet holders. SIEMENS BROS. & CO., Ltd. March 21, 1952 [March 22, 1951], No. 6940/51. Classes 16 and 146(1) [Also in Group XXV] On a telephone manual switchboard, provision is made for holding a partly completed ticket in position on the desk section opposite the speak key for the call to which the ticket relates, there being for each speak key a gripping device comprising at least one working member held captive between two surfaces diverging in the front and back direction of the switchboard so that a ticket may be inserted by pushing it between the rolling member and one of the two surfaces, removal of the ticket being resisted by the rolling member being pulled in the direction of convergence of the surfaces and thereby exerting a binding action on the ticket. As shown in Fig. 1, the desk section 2 of the switchboard and turret keyboard panel 1 have grip devices 3 opposite each speak key (not shown) comprising two captive balls 4 spaced apart and held captive in slots 11 between diverging surfaces 5, 6. The keyboard panel 1 is shaped to form the surface 6 and is slotted at 11 and a slightly resilient angle member 7 forming the other surface 5, the panel 1 and member 7 being screwed at 9 to a main frame member 8. The surface 5 is slightly lower at the front so that the balls 4 are urged to the gripping position by gravity. A ticket or sheet 13 is shown being inserted and the balls 4 will be pushed backwardly thereby to allow entry of the sheet under the balls, the balls then rolling forward to grip the ticket. As shown in Fig. 3, the grip device 3 comprises a captive soft-iron roller 14 held in a diverging groove 15 between members 7 and 16 of non-metallic, slightly resilient material. The members 7, 16 lie between pole pieces 17, 18 which are permanently polarized by a permanent magnet 19 so that the roller 14 is urged forward to grip a ticket 13 by magnetic attraction. As shown in Fig. 5, the keyboard panel 1 and desk 2 from the diverging surfaces 5, 6 and each gripping device 3 comprises two captive balls 4 each urged forwardly by a light leaf spring 20 mounted on a member 21 by screws 22, the member 21 having a space 23 behind each ball 4 and being cut away at 24 for the reception of the leading edge of a ticket 13. The panel 1 is arranged to have a certain resilience, this resilience, of at least one of the binding surfaces in all the constructions, preventing the binding action of the devices becoming an absolute lock.

Title: Devices for adjusting the angular direction of apparatus on a moving platform
IPC: G01C19/38
Filed: 1930-03-03
Abstract: 349,149. Adjusting sighting-apparatus on a moving platform. RHEINISCHE METALLWAAREN-UND MASCHINENFABRIK, 195, Ulmenstrasse, Derendorf, FœSGEN, P., 63, Reichswaldallee, and ISCHEBECK, F., 35, Scharnhorststrasse, all in Dusseldorf, Germany. March 3, 1930, No. 6942. [Class 97 (i).] Apparatus, e.g. an observation. instrument, mounted on a moving platform, is maintained in an adjusted position with reference to a system of co-ordinates fixed in space, irrespective of the movements of the platform. Several examples of such adjusting devices are given, of which that shown in the Figure is typical. The apparatus 1 to be adjusted is mounted on the constantly moving platform 2, e.g. the deck of a ship, about three axles 3, 4, 5 intersecting the point x. The vertical oscillating axle 3 carries the axle 4 mounted in the bearing 6 the axle 4 having a vertical arm forming the oscillating axle 5 upon which the instrument 1 is mounted in a bearing 7. The directing apparatus, mounted at a distance from the instrument, comprises a ring 10 suspended by a cardan joint on the platform 2 by a pair of axles 8, 9, and maintained horizontal by a pendulum or gyroscope. In the horizontal plane of the ring 10 a direction indicator is adjustably mounted by means of a yoke 11 about an axle 12, for adjusting the elevation, and a guide 13 co-operating with the ring 10 for lateral adjustment. The direction indicator comprises two parts 14, 14<1> relatively rotatable, the part 14 being fixed to the yoke 11, and the part 14<1> pivotally connected to the platform 2 by three axles in a similar manner to that of the apparatus 1. All the various axles of the direction indicator intersect in the point x<1> which is the origin of the two systems of co-ordinates, comprising axles 19, 17, 16 and the horizontal plane 10 and the plane of elevation containing the axle 12. If a telescope z, mounted on the part 14 of the direction indicator, be directed to an object by moving the yoke 11 about the axle 12 and round the ring 10, the rotation of the bearing 15 about the axle 16, of the axle 17 in the bearing 18 and of the axle 19 in the platform 2 serve to convert these movements into the oscillating system of coordinates connected with the platform 2. These movements are transmitted, either directly or by remote control, in a known manner, by conductors 20, 21, 22 to the pivoted axles, 3, 4, 5 of the apparatus 1 so that it follows the direction indicator 14. To obviate the inconvenience, at great elevations, of the axle 16 coming into the direction of the horizontal axle 12 and acting as the elevating axle, a mechanical coupling 23 is provided to suppress one degree of freedom. In a modification the extra degree of freedom is suppressed by preventing one of the axles 16, 17, 19 from rotating. The telescope z could be mounted at a distance and operate the direction indicator by remote control apparatus.

Title: Bread cooling and storage plant
IPC: A21C15/00
Filed: 1945-03-20
Abstract: 618,227. Bread cooling and storing chambers. SEVILLE, J. R., and BAKER PERKINS, Ltd. March 20, 1945, No. 7012. [Class 49] [Also in Group X] A plant in which bread loaves are cooled and thereafter stored comprises a chamber for the bread, means for circulating through the chamber cool air which is sufficiently moist to prevent undue evaporation loss, and means for alternatively circulating in the chamber air of the temperature and humidity suitable for storing the loaves. Air is driven by a fan 3 through a duct 1 into a chamber C containing stacked trolleys of hot loaves from the oven, and the air after passing through the chamber leaves the outlet 2 into a stack 6. At the suction side of the fan 3 is a chamber 4 in which air, taken in part from the atmosphere by a stack 5 and in part from the stack 6, is freed from dust and humidified by means of water sprays 22. The proportion of air passed out through the stack 6 to that recirculated is regulated by the position of dampers 7 and 8 in the stacks 5 and 6 and a damper 10 in a pipe 9 between the stacks 5 and 6, the dampers 7 and 8 being preferably opened together and the damper 10 simultaneously closed, or the reverse, by the agency of a thermostat or humidistat, e.g. by movement of an oilservo electric motor unit 27 connected through a pipe 28 to a temperature sensitive bulb 29 in the duct 1. On completion of the cooling of the loaves and consequent change over to storage conditions, air, humidified in a chamber 15 by steam boiled from water by means of an immersion heater 24, and heated, e.g. electrically, by a device 16, and preferably maintained at constant humidity and temperature with the aid of a thermostat and a humidistat, is driven by a fan 14 through a duct 12 and thence through slide-controlled apertures into the chamber C, the air leaving the chamber through slide-controlled apertures into a duct 13 for return to the fan 14. The change from cooling to storage conditions may be effected automatically by the aid of a time clock operated switch or by a switch operated upon attainment within the chamber C of a humidity or temperature indicative of cooling to the required extent.

Title: Improvements in devices for bringing to rest a moving body
Inventor: BRIDEN HORACE
IPC: G05G5/04
Filed: 1962-02-23
Abstract: 986,765. Retarding devices. COAL INDUSTRY (PATENTS) Ltd. May 7, 1963 [Feb. 23, 1962], No. 7130/62. Heading F2E. A device for bringing to rest a moving body 26 against a fixed stop 17 without rebound comprises a movably-mounted element 6 arranged to be propelled in a direction by impact with the moving body prior to the latter engaging the stop, the element having a part 18 movable with respect to the element and the element being arranged to engage a second stop after the impact whereby the direction of motion of the element is reversed, the arrangement of the element, part and second stop being such that the kinetic energy transferred to the element and part from the moving body on impact between the moving body and the element is dissipated by movements of and impacts between the element and the part, and impacts between the element and the second stop. As shown an arm 20 and an arm 22 both secured to a common shaft are initially in a position whereby the trailing face of a tongue 26 formed on the arm 22 contacts the face 19a of slot 19 formed in the element 6. The arm 20 is operated by a cam (not shown) to move it in an anti-clockwise direction so that the arm 22 opens a valve through a flexible coupling 25 and the tongue 26 thereon strikes the face 19b of slot 19 prior to engaging the stop 17. Thus kinetic energy is transferred to the element 6 and the discs 18 accommodated therein. The arm 22 continues to move anticlockwise and is brought to rest against the stop 17 with a minimum of rebound. Immediately prior to and after impact an overcentre device (not shown) which acts on the hardened insert 27 on the arm 22 comes into operation and holds the tongue 26 firmly against the stop 17. The movement of the element 6 and discs 18 continues until the face 19a of the slot 19 strikes the trailing face of the tongue 26 held against the stop 17 when the motion of the element 6 is reversed. However the discs 18 continue to move in the same direction relative to the element 6 until prior to the face 19b striking the tongue 26 again they strike the end of the channel in which they are accommodated. The moment of inertia of the element 6 about the shaft 7 is made approximately equal to the moment of inertia of the discs about the same axis, thus as a result of the impact of the disc with the element 6 the motions of both are reversed. Impacts between the element 6 and discs 18 continue until the energy is dissipated.

Title: Improvements in and relating to peeling or husking machines for grain, rice, peas and soya beans
IPC: B02B3/04
Filed: 1946-03-08
Abstract: 624,360. Husking grain and seeds. JINDRICH, V. March 8, 1946, No. 7251. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 8, 1946] [Class 58] A peeling or husking machine comprises a casing 17 containing a plurality of discs 2 which rotate at high velocity and have abrasive surfaces 26 on the circumference and which are mounted on a rotatable horizontal shaft 11 about which is mounted coaxially a perforated rotatable cylindrical member 3 which revolves with low velocity in the opposite direction. Helical ribs 4 on the interior of the cylindrical member 3 convey the grain from the entrance 5 to the exit 6. A fan 16 having a conduit 18 attached to the casing 17 withdraws waste material through the perforated cylinder 3 into the casing 17. A valve . 19 in the casing when open allows secondary air to enter the conduit 18 whereby the entraining force of the air current in the machine is reduced and the passage of the less husked grain accelerated. By closing the valve the air current is increased so that the passage of the grain is retarded and its husking increased.
