Abstract: 1,140,890. Photographic processing apparatus. INTERNATIONAL POLAROID CORP. Oct. 24, 1966, No. 47696/66. Heading G2A. An apparatus for applying a viscous processing liquid to a light-sensitive sheet comprises first and second sections mounted for relative pivotal movement and biased such as to close a transverse aperture between the two sections, the first section containing a recess for the liquid, feeding means for forcing the liquid to the aperture, a support for maintaining the sheet against the opening as it passes through the applicator, and actuating means causing the sections to pivot and open the aperture and to actuate the feeding means. As shown in Fig. 6, the second section 134 is fixed into the processing apparatus of Specification 1,140, 889 and includes a sleeve 144, having an axial slot 148 and containing a feed roller 150, and an edge 142 carrying a sealing strip 140 forming one edge of the aperture. The first section 120 is pivoted to the second section 134 about the axis of the feed roll 150, and has an edge 136 forming the other edge of the aperture. The first section contains a recess 130 for the viscous liquid which is fed thereto from a conduit 190. The sheet to be processed is passed between the applicator and the support 118, and the leading edge of the sheet activates switches carried by the support 118 to energize a solenoid 134 which causes part of the support 160 to bear on the first section 120 of the applicator to cause it to pivot relative to the second section 134 against a spring bias 156 to open the aperture, cause the feed roller 150 to rotate, and thereby apply the processing liquid to the film as it passes the aperture. The trailing edge of the film deactivates the switches as the sheet passes out of the applicator, thereby closing the aperture and stopping the feed roller 150.

Title: Apparatus for steering a vehicle and for controlling the travelling
IPC: B60K17/10
Filed: 1971-10-19
Abstract: 1361419 Steering and driving motor vehicles ROBERT BOSCH GmbH 19 Oct 1971 [29 Oct 1970] 48553/71 Heading B7H [Also in Division G3] The speed and steering of a vehicle are controlled by regulating the rotational speeds of each of two driving wheels on the vehicle in interdependence.  In the system shown, wheels 2, 3 are driven by hydraulic motors 12, 13 and are connected to tachogenerators 21, 23 which supply actual speed signals to regulators 18, 19. Desired speed signals are received from potentiometers 26, 29 supplied from a source 47 through a main potentiometer 41. In operation, the travelling speed of the vehicle is controlled by potentiometer 41 which supplies identical voltages to potentiometers 26, 29 resulting in straight line motion of the vehicle, provided the potentiometers 26, 29 are centrally set. Each of these potentiometers has a resistive half 32, 33 and a constant potential half 31, 34, so that ganged motion of their sliders causes the output from one potentiometer to vary while the output from the other remains unaltered. In this way, one of the demand signals to the regulators 18, 19 is varied and the resulting change in speed of one of the wheels 2, 3 causes the vehicle to follow a curved path. In order to make the vehicle turn on the spot, both potentiometers 26, 29 are centrally set, but the supply polarity to one of them is reversed by a switch 39. The wheels 2, 3 now rotate with equal speeds in opposite directions. Normal forward and reverse motion is controlled by potentiometer 41.  The regulators 18, 19 may be intermittently acting or continuous, and may have PID characteristics. Their output signals actuate electric motors 6, 7 through limit switches 14-17 to control pumps 10, 11 through piston-andcylinder operated servo-valves or solenoid valves operated by controlled-width pulses.

Abstract: 1,073,493. Electric meters. LANDIS & GYR A. G. Nov.29, 1965 [Dec. 4, 1964], No. 50613/65. Heading G1Q. Each E-shaped voltage magnet of a three phase induction meter has a counterpole 6 linked by a ferromagnetic bridge member 8 to the corresponding U-shaped current magnet 3. As shown non-magnetic packing 9, 10 - the thickness of which may be varied in assembly - provides for reluctance adjustment. This may however be omitted and the bridge either (a) joined directly to both the counterpole 6 and the current magnet 3 or (b) joined directly to one and spaced from the other - in which case the space may be variable by the use of a non-magnetic adjusting screw. The consequent shunting of the magnetic field between the voltage and current poles of each drive system reduces interaction between the drive systems of adjacent phases, and so compensates for rotary field error. By making the packing 9, 10 of a substance whose reluctance is temperature dependent, the meter may be temperature compensated.
