Abstract: 1,265,408. Photographic film units. POLAROID CORP. Dec. 24, 1969 [Dec.30, 1968], No. 62790/69. Heading G2A. In a film unit comprising a photo-sensitive sheet 12 and a second sheet 14 which receives an image from sheet 12 by diffusion transfer, the two sheets are maintained in face-to-face relationship by a retaining sheet 20 which is secured to the margins of the two sheets, sheet 14 also being embossed at its trailing end to form a number of ribs 54 which abut sheet 12 to provide spaces in which excess processing liquid may be collected. The film unit is of the type in which the processing liquid is initially held in a rupturable container, Fig. 1 (not shown), at the leading edge of the sheets. The container is ruptured by drawing the sheets between rollers 46, after which continued movements of the sheets between the rollers causes the liquid to be spread between sheets 12 and 14. Sheets 12 and 14 are of the same width, but sheet 14 is longer than sheet 12 at the trailing end. The retaining or binding sheet 20 is in the form of a rectangular frame larger than sheets 12 and 14, and having a rectangular opening 22 which defines the size of the image produced. The lateral edge portions 24 of binding sheet 20 are secured around and to the outer marginal portions 30 and 32 of sheets 12 and 14. Similarly the trailing edge portion 28 of sheet 20 is secured to and folded round trailing edge 36 of sheet 14 and also secured to trailing edge 34 of sheet 12. Thus sheets 12 and 14 are effectively bound to each other along three sides, so that any escape of processing liquid is prevented. As shown, the trailing end 36 of sheet 14 is embossed to form a series of short longitudinal ribs 54 joined together by a transverse rib 52. Ribs 54 function to provide spaces in which excess processing liquid may be trapped and retained, as shown in Fig. 5, which represents the position after the sheets 12, 14 have been drawn almost completely through the rollers 46. Rib 52 has been bonded by pressure to the wet surface of folded-end 28 of sheet 20, which prevents flowback of liquid from the trapping space to the image area. Air trapped during the spreading of the processing liquid, and pushed along with it, is also collected between ribs 54. Means such as slits 60 or pinholes 62 may be provided to allow this air to escape.

Abstract: 1,266,158. Motor vehicle controls. JOSEPH LUCAS (INDUSTRIES) Ltd. 30 June, 1969 [25 July, 1968], No. 35484/68. Heading B7H. In a motor vehicle having servo-assistance for actuation of the engine throttle 12 by the throttle pedal 13, the servo-assistance is removed under predetermined conditions so that the driver must press the pedal harder when those conditions exist. The throttle 12 is linked to a bellows 15 connected to the inlet manifold 11 by a pipe 17 including a restrictor 18. A light spring 14 is arranged to lift the pedal 13, and a heavier spring 16 to extend the bellows 15. A valve part 23 on the pedal 13 co-operates with a valve part 22 on the bellows 15 so that when the pedal is depressed the pressure in the bellows decreases and the bellows collapses to open the throttle 12. A valve 19 is opened by a winding 21 connected to a speed-responsive circuit when a predetermined engine speed is reached so that the servo-assistance is removed and the driver is warned that he has reached the predetermined speed which may be set on a device manually operable by the driver. Use of excessively large throttle openings at low engine speed will also be indicated by loss of servo-assistance due to low depression in the inlet manifold 11.

Abstract: 1318858 Substation circuits STANDARD TELEPHONES & CABLES Ltd 13 Sept 1971 42550/71 Heading H4K A circuit for a push-button subscriber's instrument having a latching electromagnetic relay to provide loop disconnect dialling impulses includes a circuit, additional to that for driving the relay during impulsing, for closing the relay contacts when the instrument goes "off hook". In the circuit shown, capacitor C2 is charged up from the exchange battery through lines L1, L2 and when the cradle switch contacts GS1, GS2 are closed, it discharges through relay winding LR into capacitor C1, thereby closing the loop through contacts lr1 which are latched. The MOST circuitry M controls the operation of the off-normal contacts ONC and the release of relay LR to provide impulsing. If contacts lr1 inadvertently open, e.g. due to shock when the instrument is dropped, capacitor C2 will charge due to the resistance imposed by T1, T2 and relay LR will be re-operated. In a modification, the whole circuit is isolated from the lines by the cradle switch contact and a relay operating circuit is formed when this contact is closed, Fig. 2 (not shown).

Abstract: 1319143 Automatic voltage control GENERAL BATTERY CORP 17 Oct 1970 49414/70 Heading G3R [Also in Division H2] A battery 30 is charged by a circuit comprising a "high-leakage" transformer 22, a rectifier 24 which provides through a resistor 31 a continuous (trickle charge) current to the battery and a controlled rectifier 34, whose gate electrode 38 receives a voltage dependent on the battery voltage and that provided by a Zener diode 49, the arrangement being such that the rectifier 34 is conductive or non-conductive according to whether the battery voltage is below or above a predetermined level. The rectifier 34 may act as a gatecontrolled switch or as a variable impedance, in which case it has a current conduction characteristic which gradually decreases in accordance with the applied gate voltage down to a predetermined level at which conduction ceases. The control voltage of the rectifier may be adjusted by the tap 40 of variable resistor 41 whose position also determines in part the predetermined level at which on/off regulation occurs. Protection against line transients is provided by the transformer 22. In a three phase embodiment, Fig.4 (not shown), the transformer has a deltaconnected primary and six secondary windings arranged in a double-star connection with a respective rectifier in series with each winding, one star and rectifier supply providing the continuous current to the battery and the other star and rectifier supply being connected to the rectifier 34 and its gate control circuit.
