Title: Control arrangement for installations, more especially ships' steering gears
IPC: G05D1/02
Filed: 1962-08-17
Abstract: 990, 287. Electric positional control. SIEMENS-SCHUCKERTWERKE A.G. Aug. 17, 1962 [Aug. 18, 1961], No. 31761/62. Heading G1N. In an electric control system of the kind in which a control signal actuates a control unit to effect the desired control and to cancel the control signal, the control unit has at least two input stages responding to different values of control signal, the most sensitive input stage effecting the starting of the control operation while a less sensitive stage determines the stopping when the control signal falls below the threshold value of such stage. This is said to combine a high input sensitivity with avoidance of hunting due to overshoot. As shown, Fig. 1, in a control system for a ship's rudder 4, the desired position of the rudder as set into a transmitter 1 is compared with the actual position derived from a second transmitter (not shown) in a receiver 2, the error signal from the receiver being fed to a control unit 3 comprising two control paths II which respond to different potentials, according as the rudder is to be moved in one direction or the other, to actuate one of two clutches 6, 7 to enable a continuously-running motor 9 to set the rudder through gearing 10, 11. Each control path II comprises a circuit as shown in Fig. 2. The error signal is supplied to two signal converters U1, U2, having different threshold values which may be adjusted by rheostats R1, R2. U1 responds first, passing a one-signal to an inverting gate N2, which supplies a zero-signal to another inverting gate N1 and to the first input to a memory store M, which does not, however, erase the existing one-signal at the corresponding output of the store M. Thus, AND-gate X1 receives two one-signals, from N1 and M respectively, and produces a one-signal to operate the relevant clutch. When the error signal reaches the threshold value of U2, U2 passes a one-signal to the second input of memory storeM, thus transferring the output onesignal from the first to the second output of M. The output from X1 becomes zero, but the operation of the clutch is maintained by a one-signal from a second AND-gate X2 whose inputs are connected to U2 and the second output of M respectively. When the error signal falls below the threshold value of U2, the output of X2 becomes zero and the clutch opens. The input stages preferably comprise voltage dividers with voltage-sensitive semi-conductors, e.g. threshold value diodes, in their circuits. In systems having variable-speed control action, the less sensitive stage is chosen to stop the control action at a point determined by the follow-up of the controlled apparatus. The control units may be so interlocked that only one control path at a time determines the control action.

Title: Improvements in or relating to direction finding radio receiving systems
IPC: G01S1/02
Filed: 1935-11-20
Abstract: 467,892. Directive wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and WRIGHT, G. M. Nov. 20,1935, No. 32121. [Class 40 (v)] In a direction-finding system employing a plurality of directional aerials, or an aerial system including a directional member in which the phase of connection to the receiver is periodically changed, the signals are fed successively to, and compared by an indicator, e.g. a cathode ray tube, so arranged as to respond not merely to integrated signals but to distinguish between derived and interfering signals. In Fig. 3, 1 and 2 are mutually perpendicular rotatable frames tuned by condensers 3, 4. The diodes or other rectifiers 12, 14 are alternately made conducting by low frequency voltage supplied by the transformer 17, 18, the rectifiers alternately connecting the frames to the tuned circuit 6, 7, coupled to the receiver 9 by coil 8. 10a is a cathode ray indicator, one pair of plates being supplied from the receiver 9 and the other pair from the source of low frequency. Diodes 20, 21, which are saturated, are for current limiting to reduce the necessary size of diodes 12, 14. The pattern produced on the screen of the cathode ray tube consists of two sections corresponding to the output from the two frames which are rotated until the amplitudes of the deflections are equal ; this gives the direction of the incoming signals. The general level of the wanted signal can be seen on the cathode ray tube despite any deflections due to interference. In the modification shown in Fig. 5, the loop aerial 25 has its phase reversed by the double diode 32 which is switched by a low frequency voltage supplied by the transformer 13, 17. The output from the tuned circuit 34 is added to the output from the non-directional aerial 26 and fed via the amplifier 54 to the receiver 9 and cathode ray indicator 46, 47, 48, 49. The indications on the tube are adjusted to equality by rotation of the loop aerial in the same manner as in Fig. 3.

Title: Improvements in the manufacture of footwear from thermoplastics
IPC: B29C48/08
Filed: 1949-12-15
Abstract: In making footwear from thermoplastic synthetic materials in which an intimate mixture of the thermoplastic with plasticisers is subjected to structure-orienting treatment, the resulting sheet is cut into strips and converted by means of a heated worm extrusion machine into a continuous rod which is cut up into pieces of about the length of the required shoe, and the resulting pieces are introduced while still warm into a shoe press tool or mould and are rapidly pressed under high pressure and the article is removed from the mould after cooling to permanence of shape.  A suitable material is one comprising 65 parts by weight of polyvinyl chloride and 35 parts of a plasticiser such as dioctyl phthalate, dioctyl sebacate, methyl acetyl recinoleate, trioctyl phosphate and mixture of the same.  The material is worked in a stirring or kneading machine and then passed through a rolling mill, the rolls of which are heated to about 145 DEG  C.  The nozzle of the extrusion machine is preferably 30-35 mm. in diameter. The moulding pressure is between 100 and 1,000 kgs. per sq. cm. The time for the shoe to cool in the mould is about 2 1/2 minutes.  Shoes may be produced by the method of the invention with apertures of any desired shape and position, with metal inserts for reinforcement, with inserts of wood or cork for lightness, and with various patterns impressed on their surfaces. The use of floating pistons to maintain the pressure during cooling is an advantage, and the mould should be designed so that the flow of material in it is unobstructed.

Abstract: 944,352. Combination locks. MASTER LOCK CO. Sept. 8, 1961, No. 32338/61. Heading E2A. A combination lock 29 comprises a lock casing 30, a latching bar 22 reciprocatably mounted relative to the casing, a lock bolt 31 reciprocatably mounted in the casing and engaging the latching bar to control reciprocation thereof, a number of notched tumbler discs 50 rotatable within the casing on an axis perpendicular to the path of movement of the bolt, means including a tumbler disc driver plate 47 rotatably mounted coaxially with the tumbler discs 50 for turning the tumbler discs to a predetermined position wherein their notches 53 are in registration, and a lock bolt controlling-assemblage operatively mounted within the casing and having pivotal lever means 61 projectable into the tumbler disc notches when the same are in registration in a predetermined position whereby the lock bolt 31 is free to reciprocate upon reciprocation of the latching bar 22. As shown, the lock is applied to the hinged door 20 of a locker 21, the latch bar 22 being mounted at the free edge of the door and adapted to be raised and lowered to bring a shouldered slot 23 into and out of latching engagement with a latch dog 24 mounted on the door frame. The arrangement is such that when the lock 29 is in locked condition, the bolt 31 thereof prevents upward movement of the latching bar 22 by an external handle 26 connected thereto until the tumbler discs 50 have been set by a setting knob 33 to align the notches 53 of the discs 50 in a position where the notches are engaged by a nose 61<SP>1</SP> of the lever 61. In this position of the lever 61, Fig. 6, the bolt 31 is freed for upward movement in response to upward movement of the latching bar 22 by the handle 26 and simultaneously an inner portion of the nose 61<SP>1</SP> engages an adjacent end portion of a spring- loaded slidably mounted slide 65, a lug portion 65<SP>1</SP> of which is, in the locking condition of the lock, engaged in a recess 59 of a lever retaining bar 55 on which the lever 61 is pivoted. Continued unlatching movement of the handle 26 moves the bolt 31 and the bar 55 upwardly against a spring 62 due to the engagement of the portion 57 of the bolt with an angled portion of the lever 61. The discs 50 are also rotated until the notches 53 become disengaged from the nose 61<SP>1</SP> of the lever 61, when the latching bar 22 is freed from the latch dog 24. After the door has been opened and the handle 26 released the parts are returned to the position shown in Fig. 8 and the door can be reclosed and automatically locked without further manipulation of the dial setting knob 33. In Fig. 9 (not shown) the lock is applied to a door adapted to open at the opposite edge to that shown. The outermost of the tumbler discs 50 is serrated to prevent "picking" by "feeling" the combination. Specifications 944,353 and 944,354 are referred to.

Abstract: 245,162. Johns, C. M. Dec. 27, 1924, [Convention date]. Stability, determining. - Apparatus for determining the centre of gravity ships based on the fact that a ship when rolling rotates about a longitudinal axis passing through the centre of gravity, comprises a pendulum p<2> mounted on knife edges m<2> on a support g adapted to be secured in any position on a perpendicular guide rod s arranged in the median line of the ship. When the ship is rolling, the support with its pendulum is adjusted along the rod s until the pendulum shows no movement relatively to the ship as is indicated by a spirit level w<2> mounted on the head of the pendulum. The support then indicates the fraction of the centre of gravity on the graduated scale s. To assist in determining the approximate position of the centre of gravity prior to final adjustment, a second pendulum p' identical with the pendulum is mounted on the fixed support t. In carrying out this initial operation, the pendulums are set swinging under the roll of the ship, and from an observation of their maximum respective oscillations, the approximate height of the centre of gravity of the ship can be deduced.

Patent GB-326930-A (GB)
Abstract: 326,930. Harries, A. W. Jan. 25, 1929. Autographic cash recorders.-The feed of the voucher and record strips towards the front of the apparatus is effected by manual depression of a lever 12 extending to the rear and operating the feed-rollers 6 through spring and trip mechanism. The strips 1, 2, 3 stacked in zig-zag fashion pass over guide rollers 4 and the writing-table 5 to a pair of rollers 6 secured to a shaft 30 and normally engaged by a pressure roll 7 geared with the shaft. A toothed quadrant 16 meshes with a pinion 31 free-wheel mounted on the shaft and is connected to a rod 17 guided between rollers 21 on a pivoted arm 14 and drawn towards this arm by a spring 18. The operating lever 12 pivoted at 11 carries a roller 13 bearing against the arm 14 which is urged towards the left by a spring 28 anchored to the casing. The arm 14 is shaped at its upper end to co-operate with a pawl 24 mounted on a disc 25 connected by a rod 26, Fig. 4, with a detent 27 normally locking the shaft 30. When the lever 12 is depressed, therefore, the arm 14 stretches both springs 18, 28 until by the tripping of the pawl 24 the shaft is freed to be rotated by the quadrant under the action of the spring 18. The rod 26 under spring control immediately returns towards home position so that the detent can re-lock the shaft at the end of its rotation. Registration of the various strips is ensured by stationary cams 42 which cause the protrusion of spring pins 35 from the rollers 30 into holes in the strips at the end of each feed. The roll 7 is grooved to receive the protruded pins and is also automatically raised by cams 41 fixed on the shaft 30. The roll 7 may also be lifted when desired by turning a knurled disc on a rod carrying an eccentric 49 engaging under the roll.
