Title: Device for preventing punching in accounting machines provided with card-punching apparatus
IPC: G06C11/08
Filed: 1960-12-14
Abstract: 910,246. Calculating-machines. KIENZLE APPARATE G.m.b.H. Dec. 14, 1960 [Dec. 18, 1959], No. 43021/60. Class 106 (1). In an accounting-machine with a pin-carriage for setting purposes and a card-punching mechanism, punching is prevented in machine operations in which no amount has been set in the pin-carriage and in which, therefore, the latter has not moved from its rest position. The invention is applied to the machine described in Specification 844,501 in which racks 3 controlled by the pin-carriage 4 position punch selectors 18. A slide 31 is now arranged at the right of the pin-carriage so that if the latter has received no entry, the slide 31 will be depressed when the pin-carriage is lowered in known manner during each entry operation. The slide 31 has an ear 35 which blocks a lug 36 of a link 37 unless the slide is depressed in the manner just described. In the latter case, the link 37 is able to move rearwards under the action of a spring 48 and under the control of a cam lever 42 and in so doing, breaks a driving connection between a cam-actuated push-rod 59 and a rod 67 which initiates the punching operation. In an alternative arrangement, punching is initiated by a solenoid in the circuit of which are timing contacts and normally-closed contacts which are opened by the slide 31 when it is depressed by the pin-carriage. On both arrangements, punching may be prevented through the same devices under the control of the paper carriage.

Title: Process and apparatus for monitoring the viscosity of the melt in the melt spinning of synthetic fibres
Inventor: JNR THURMAN RALSTON JONES
IPC: D01D1/09
Filed: 1968-09-10
Abstract: 1,205,160. Apparatus for monitoring the viscosity of the melt in melt spinning. E. I. DU PONT DE NEMOURS & CO. 10 Sept., 1968 [13 Sept., 1967], No. 43027/68. Heading B5B. A melt-spinning apparatus including a device for monitoring any difference between the viscosity of the melt immediately prior to extrusion and the viscosity desired at that stage, comprises a metering gear pump 1 (Fig. 1) which forces the polymer at a constant rate through conduit 2, sand filter 5 and bottom screen 6 in the cavity 3 of a melt-spinning head. The melt is then forced through ducts 7 in the bottom of the cavity into the disc-shaped space 8 immediately above the spinneret plate 19. The melt is then forced through the spinneret capillaries 9 to form extruded filaments 10 which are quenched, passed over rotating roller 11 and then wound up in a package 12. The pressure of the polymer in space 8 is measured by means of pressure transducer 13, converted into an electrical signal in bulb 14 and indicated and recorded by recorder 15. The temperature of the spinneret is measured by thermocouple 16 and is indicated and recorded by recorder 17. In operation, the temperature of the spinning head is maintained constant at the desired level by electrical or fluid heating means with the assistance of suitable insulation. The polymer finisher 20 has an associated viscosity regulator 21 which, in the case of condensation polymer, regulates the vacuum within the finisher, thereby controlling the polymer viscosity. Integrater and controller 22 determines the actual viscosity as based on the teinperature and pressure above the spinneret, compares this with the desired viscosity, and transmits the appropriate signal to regulator 21. The pressure and temperature of the polymer melt immediately above the spinneret being known, the melt viscosity may be calculated or taken from a previously prepared table based on the constant flow rate of the melt through the spinneret and the cross-sectional area of the capillaries in the spinneret, the capillaries thus being used as a sensitive and accurate viscometer.

Title: Missile with brake flaps
IPC: F42B10/14
Filed: 1968-09-11
Abstract: 1,213,505. Missiles having braking flaps. WERKZEUGMASCHINENFABRIK OERLIKEN BUHRLE A.G. 11 Sept., 1968 [11 Sept., 1967], No. 43243/68. Heading F3A. Missile, particularly a rocket, having brake flaps which can be swung out of an inactive position into a braking position against an adjustable stop, rebound of the flaps upon striking the stop being reduced to a minimum by latches. The latches comprise a wedge 67 urged inwardly, between a surface 74 of the rocket nozzle and a hub 58 of a flap, by a spring 69. The centre of rotation O of the hub is eccentric with respect to the centre P of its cylindrical surface 76. As the flap is being swung by a spring into its braking position, the wedge is first thrust outwards by the hub surface 76, but, after a certain point, is thrust backwards by spring 69 and remains in contact with the hub. Rebound of the flap from the stop (62, Fig. 1, not shown) is powerfully damped by a frictional force which appears because the wedge is clamped between surface 74 and hub 58. The braking flaps are held in the inactive position by cams extending from the hubs of erectible fins (13) normally folded alongside the rocket nozzle (3). Whilst the fins are being erected by a spring (19), they are also moved rearwardly, and the cams pass through slots in the forward ends of the braking flaps to free them for erection.

Title: Improvements in or relating to apparatus for delivering measured quantities of liquids
Inventor: ABSOLON ERIC WILLIAM
IPC: B01D19/00
Filed: 1961-12-04
Abstract: 969,050. Dispensing liquids. AVERYHARDOLL Ltd. Nov. 28, 1962 [Dec. 4, 1961], No. 43305/61. Heading A4T. [Also in Division G3] Measured quantities of liquid fuel are supplied from a tanker vehicle to a storage tank by means of apparatus comprising a gas separator 10, Fig. 1 to which liquid flows from the tanker under gravity, and from which it passes to a displacement meter 12 that supplies liquid to a flow controlling valve 13 and a shut-off valve 14 the outlet 15 of which leads to the tank. The meter 12 drives a register, whilst a pre-setting mechanism automatically closes valve 14 when a given quantity of fuel has been delivered. The pre-setting mechanism and register may be dispensed with. The separator 10 incorporates a chamber of sufficient size to enable the liquid to dwell therein for a period, any gas separating from the liquid collects above it and is periodically released; means responsive to the quantity of gas in the separator controls the valve 13. The spring-loaded obturator 13, Fig. 5, is a cup-shaped member 19 in which is a control chamber 24 of larger diameter than the seat 21, and liquid enters the chamber 24 via an orifice 25, the area of which is adjustable by a threaded stem 27. The outlet 30 from the chamber 24 is controlled by a pilot valve 35, Fig. 3, in the separator, which valve is mounted on diaphragms and actuated by a float 37 on parallel links 38, 39, the former having a tail 46 that cooperates with a spring-loaded pin 51. The float buoyancy may be altered by adjusting a weight 52 through a knob 58. The discharge of gas from the separator is effected by a second servomotor system comprising a valve 61, Fig. 4, operated under the control of a pilot valve 65 actuated by a float 52; the outlet 64 of valve 61 is opened when enough gas has collected to depress the liquid level in the separator. If there is a large quantity of gas in the liquid, the latter may not remain in the separator a sufficient time to permit of separation so that the effective liquid density is reduced and the float 37 falls whereupon the valve 13 moves towards the closed position to reduce the rate of flow and give more time for separation. So long as the float does not fall far enough for the tail 46 to engage the pin 51 the degree of restriction of valve 13 varies directly with the proportion of gas entrained in the fuel. A substantial increase in this proportion is necessary to cause complete closure of valve 13.
