Title: Warning devices for lamp failure in vehicles
IPC: B60Q11/00
Filed: 1961-10-10
Abstract: 963, 713. Lamp failure alarms. C. PERATTO. Oct. 10, 1961 [Oct. 12, 1960; Nov. 3, 1960; Nov. 9, 1960], No. 36374/61. Heading G4N. [Also in Division B7] A rear view mirror 16 for a road vehicle is mounted in a case 14 housing a lamp failure alarm device comprising two shutters 10, each of which is attached to the moving parts of a device 4, or 104, of the ammeter, or voltmeter, type. Failure of one of the lamps 1, 101 on the vehicle e.g. a rear lamp, actuates the corresponding device 4, or 104, to move the associated shutter from its normal position between a tube 18 and a lamp 8, whereby a glass cover 17 at the end of the tube is illuminated. A separate lamp 8, tube 18, and cover 17 is provided for each shutter. Alternatively, the shutters may be arranged to obscure the associated lamps 8, in the event of a lamp 1,101 failing. Variable shunt resistors 3,103 may be adjustable by knobs on the exterior of the casing, (Fig. 3, not shown). The mirror is tiltable about its lower edge by a lever 19 attached to its upper edge and held by friction within a slot 20. The case 14 may also include a lamp 22 for illuminating the interior of the vehicle through a glass panel 21.

Title: Juice squeezer for citrus fruits
IPC: A47J19/02
Filed: 1976-09-02
Abstract: 1518407 Fruit juice squeezer ACKERET DESIGN STUDIOS 2 Sept 1976 [6 Aug 1976]  36408/76 Heading A4C A fruit juice squeezer comprises a base 14 formed with a lip 20 and handle 24, a strainer 12 non-rotatably mounted on the base and formed with a hexagonal head 38 which non-rotatably supports a cone 10, the cone having a member 40 with a circular periphery which journals a cleaning element 16 formed with a spiral blade 56 for removing flesh from a raised section 32 of the strainer and despositing it in a trough 35, both the raised section and trough having slots 34, 37 for the juice to drain into the base. The element 16 has a handle 63 and is guided on the outer rim 36 and the inner rim 33 of the strainer. In a modification the cleaning element, cone and base are relatively non-rotatable and flesh is cleared by rotating the strainer. In a further modification the element sits on the rim of the strainer and in use is moved therearound, the inner end of the blade being free. The trough need not extend around the complete circumference of the strainer but may be formed by two oppositely disposed sectors. A pair of cones may be provided and integrally connected, the element being a straight blade extending across the strainer and leaving the flesh on diametrically opposed areas between the cones. In Fig. 11 two cones 451 and a cleaning element blade 450 are formed integrally, the cones in use being moved downwards against a spring 452 so that notches 455 engage recesses 456 and prevent movement of the cones and blade relative to the strainer 453 and base. The cones and blade may otherwise be rotated relative to the strainer to remove flesh away from the cones. As an alternative to the locking notches and recesses a single clip may prevent the cones and blade from rotation. The squeezer may be rectangular in plan with a cone mounted above the strainer with the blade moving rectilinearly to remove flesh into troughs at each end of the strainer. The pairs of cones may be rotated by a motor through gearing, respective strainers rotating with the cones and the cleaning blade being stationary. Alternatively the blades may rotate with the cones and the strainers remain stationary. In a modification the blades may be manually pivoted into and out of operative positions with respect to the strainers. The components of the squeezer may be made from plastics material.

Title: Control System for Flying Splicer Drives
IPC: B65H19/22
Filed: 1968-07-31
Abstract: 1,187,525. Automatic control of moving strip. WESTINGHOUSE ELECTRIC CORP. July 31, 1968 [Sept.5, 1967], No.36517/68. Heading G3R. A system for controlling a drive motor 88 of strip material winding and/or unwinding apparatus, particularly flying splicers used in the paper and man-made-fibre industries, includes means for selectively connecting one of the parallel strip speed responsive or strip tension responsive servo loops to the motor control apparatus while the other is disconnected and vice versa. The paralleled speed and tension loops may drive inner loops such as current or voltage loops providing auxiliary functions such as torque limit. The tension control circuit 102 includes an operational amplifier 148 having a feedback path including a current limiter 150 and receiving a tension signal from a force transducer 72 on lead 70 and a desired tension signal, from a reference source 156, of one polarity for unwinding and opposite polarity for winding. The operator can vary strip tension by the top on the potentiometer 156. When a relay 140 is de-energized, a high positive voltage saturates amplifier 148 and effectively disconnects it from the control for motor 88, the system then being under speed control. The speed control circuit 104 has an operational amplifier 130, a current limiter 132, and receives a calculated surface speed signal on lead 118 (or it could be an actual surface speed signal from a tachometer) and a speed reference signal from tachometer generator 76 on lead 74. With switch 138 in its other position, a signal from tachometer generator 124 is applied to amplifier 130 rather than a calculated or actual surface speed signal. When relay 140 is energized, a high positive voltage saturates amplifier 130 and effectively disconnects it from control of motor 88. Contacts 146 controlling relay 140 are actuated by limit switches during roll changing, (see Figs.1A-1E and 2A-2F, not shown), so that the system is under tension control during a splice. Biased diodes 160, 162, provide for the selective connection of the speed or tension loops. A roll diameter detector amplifier 110, receiving an actual surface speed signal on lead 116, a calculated speed signal on lead 118 and a small A.C. signal from a source 120, operates a servomotor 122 moving a tap 128 on a voltage dividing potentiometer 126 and also moving a tap on potentiometer 164 to adjust the gains of the speed and tension loop as a function of roll diameter. The voltage on tap 128, and hence on lead 118, is proportional to the product of the output voltage of tachometer generator 124 and the shaft position of servomotor 122. The amplifiers 96, 110, 130, 148, are P + I controllers or P + I + D controllers as in U.S. Specification 3, 324, 363. A digital or relay operated roll diameter detector may be used. Swing roll position feedback may give the tension signal.

IPC: B30B15/14
Filed: 1968-07-31
Abstract: 1,176,095. Clutch control systems. L. SCHULER G.m.b.H. 31 July, 1968 [1 Aug., 1967], No. 36539/68. Heading F2L. [Also in Division G1] In a method of starting cyclically operating machines required to work synchronously in predetermined phase relationships to one another the starting of each machine is initiated when the point in its cycle at which the machine is resting is appropriately in advance of its correct phase relationship having regard to the starting behaviour of the machine for the latter to drop into synchronism on reaching its operating speed. Presses 4 are operated with a phase difference at 45 degrees between presses and are driven by a control motor 1 via shaft 2. The motor 1 may be replaced by the drive shaft of a control machine for the press line, e.g. an eccentric shaft of the control press. The shaft 2 drives synchros 3, each adjusted to give the required phase difference and each driving a rotating brush set 5 over a commutator 7 having contacts 6. Each contact 6 is connected to a contact of a second commutator 8 over which a brush set 9 rotates, the latter being rotated synchronously with the ram drive and synchro 10. When a predetermined voltage is achieved in line 11 and circuit 12 a starting signal acts on a control means 20, e.g. a coupling, which is interposed between a drive motor 18 and the press. The voltage may be adjusted by potentiometers 13 and a tachogenerator 19 rotating with the control motor 1 feeds a voltage corresponding to the speed of rotation to the circuit 12. The signals produced by synchros 10 have a voltage varying with the phase difference or the phase difference could be signalled by the duration of a pulse or by the frequency of an alternating current. Operation.-When brush set 5 runs on a contact 6 corresponding to the contact on the commutator 8 on which the brush set 9 is standing a circuit 14 operates a relay 15 which closes a normally-open switch 16 to close the synchro supply circuit 17. Since brush set 5 is 90 degrees in advance of synchro 3 the latter has a phase difference of 90 degrees in relation to brush set 9 and synchro 10 and this causes a maximum voltage in line 11 which decreases as the position of synchro 3 approaches that of synchro 10, the starting signal being initiated when the voltage has decreased to the predetermined value.

Filed: 1928-12-12
Abstract: 326,479. Marks, Sir G. C., (Bates Valve Bag Corporation). Dec. 12, 1928. Automatic-feed weighers; pendulumweight apparatus.-A weighing device of the pendulum type is provided with means for feeding material into a receptacle supported on the weighing device, and control means for stopping the feed operable by the aid of the pendulum at a predetermined point in its movement. As applied to a machine for filling valve bags placed on a feed spout 47 carried by a bag support 43, the weighbeam 37, fulcrumed on knifeedges 36, carries by means of brackets 39,40 a guide 38 along which a pendulum weight 54 may be adjusted by means of a screw 55. The guide 38 is parallel to the load arm of the weighbeam. The movements of the weighbeam are restricted by stops 75. An adjustable spring 77 acts against the pendulum until a main feed propeller is arrested by the disconnection of a driving clutch after which an auxiliary propeller continues the feed until arrested by electrical means. The weight 54 is so proportioned that the weighing device does not begin to move until the greater portion of the charge has been filled into the bag. The spring 77 preferably reaches the limit of its expansion and becomes inoperative when the main feed is cut off. The weighing device may be modified as shown in Fig. 4, wherein the weighbeam 102 carries graduated bars 116, 119 bearing sliding weights 117, 120 for fine and large adjustments. The weight 120 also carries a verticallyadjustable weight 137, and the graduated bar 119 may be adjusted horizontally by a graduated micrometer head 123 for providing a further fine adjustment. An indicating pointer 127 is actuated by a flexible band 135 connected to the weighbeam. In a further modification, Fig. 6, the indicating pointer is operated in a plane at right angles to the beam by a rack 171, and the load support 145 is suspended from the beam.
