Abstract: 1,227,199. Can openers; removing corks. W. STEINER. 6 Nov., 1968 [7 Nov., 1967], No. 52676/68. Headings B8D and B8T. A multipurpose utensil operates either as a can opener or a cork popper, both mechanisms being mounted on a housing and operated by a common lever which drives a piston to generate air pressure for the cork popper. The utensil has other mechanisms to operate as a conventional corkscrew, can top piercer or bottle opener. Use as a can opener.-The lever 2 is mounted on a shaft 28, between legs 31 of a U-shaped bracket 29 which a bolt 33 passes through a slot 32 in the legs 31 and the lever 2 to guide the bracket 29 for movement relative to the housing 1. The bracket 29 is raised or lowered on the bolt 33 by an extension 34 of the slot 32. Actuation of the lever 2 raises the bracket 29 to its highest position (not shown) where it remains supported by a pin (not shown) on housing 1 during the can opening operation. A toothed segment 35 engages with a pinion 36 mounted on a shaft 37 of a transport wheel 8, Fig. 4, which is mounted on the bracket 29 while an internally toothed bore 38 of the pinion 36 engages a pawl 40 biased by a spring 39 to constitute a ratchet and pawl mechanism which drives the wheel 8 in one direction only. Raising the bracket 29 engages the transport wheel 8 with a cutting wheel 9 having support rollers 10 disposed on either side which are biased against a can top 56 by a spring 53, and squeezing the lever 2 in and out relative to the housing 1 causes rotation of the transport wheel 8 so that the cutting wheel 9 opens the can. The transport wheel 8 has inclined teeth to grip the can during transport. To open very small cans the transport wheel 8 has a central aperture (55), Fig. 1 (not shown), which can accommodate a suitable key to roll up the can covers. Use as a cork popper.-A needle valve (4), Fig. 2 (not shown), and needle (6), stored during non-use in compartments 11, 12, 13, are threaded into a recess 21 by means of a thread (5) around the needle valve (4) and then inserted through a cork. Activation of the lever 2 when the bracket is in its lowest, i.e. Fig. 3, position alternatively raises and lowers this bracket about the bolt 33 and also reciprocates a spring-biased piston 16, both movements displacing air through channels 22, 23 to pop the cork. The threaded portion (5) may serve as a conventional corkscrew. Other uses of the utensil.-Bottle tops may be removed or can tops pierced by respective ends 44, 45 of a steel tool 43 which slides in grooves 42. The amount of sliding being limited by the movement of a spring-biased screw 46 in a slot 47. A glass hand cutting wheel 57 may also be provided to serve as means for removing bottle caps or hoods. A selector switch (7), Fig. 2 (not shown), correctly aligns the can opening and cork popping mechanisms for their use. Parts of the housing 1 may be of plastics.

An arrangement for automatically controlling the entrance 2 and exit 3 of a car park 1 comprises a device 7 which reads from a parking ticket the entrance time encoded thereon, calculates and receives the money due, and then marks upon the ticket the latest possible exit time such that the ticket is only able to open the exit barrier 5 before this time. An entering vehicle activates an induction loop 10 to deliver a ticket, punched or perforated in code with the time, from a distributer 6, and to open a barrier 4 upon removal of the ticket, which barrier is closed by the vehicle activating a loop 11. The driver returns through an entrance 9 to insert the ticket in a device 7 which shows the amount due upon a screen. After payment a time calculated by adding an adjustable period to the actual time is punched in code upon the ticket. The ticket is then inserted in a device 8 to open the barrier 5, which is afterwards closed by activation of a loop 12. The car park may be multi-storey.

An attachment 5 enabling a lift truck 1 with front-mounted fork arms 2 to move lengthy loads extending either parallel to or perpendicular to the longitudinal axis of the truck, comprises a beam 6 supporting sliding fork arms 7 and hollow fork arms 8, which are spaced apart by a distance equal to the spacing of the fork arms 2 so that the latter can be slid into the arms 8 and which are interconnected by a bar which acts as a pivot for a pair of arms 11 formed with apertures for the reception of one of the fork arms 2. Arms 17, supporting castor wheels 18a, 18b are pivotally connected to the fork arms 7. In operation, the attachment is positioned in front of a storage rack for elongated articles and the truck is disengaged from the attachment. The truck is then manoeuvred to insert the fork arms 2 into the hollow fork arms 8 and the lifting carriage 3 is raised, allowing the arms 17 to pivot downwardly, Figs. 6, 7 (not shown), thereby permitting the truck to be driven forwardly to engage and extract the load. The attachment is then lowered to the ground and the fork arms 2 are disengaged from the fork arms 8 and reinserted into the apertures in the arms 11 for transportation of the load. In a modification, Fig. 9 (not shown), the arms 17 are adapted to be pivoted to, and held in, a position in which the wheels extend upwardly, thereby allowing the fork arms 8 to be lowered to a position adjacent the ground. In a further modification, Fig. 13 (not shown), the attachment is supported by hooks on the lifting carriage 3. In the modification illustrated in Figs. 14-16 (not shown), the arms 17 are pivoted about inclined axes. Each end of a particularly long and flexible load may be supported by an auxiliary carriage, Fig. 18, comprising a frame 47-49 mounted on castors 52 and supporting removable load. engaging fillets 58. The frame is so constructed that an aperture 63 is provided whereby the carriage may be engaged and raised by a fork arm of a lift truck similarly to the engagement of a fork arm with the attachment 5, Fig. 1.

In a multistage transistor amplifier a signal input terminal is connected to one input of a differential amplifier stage whose output is fed to a plurality of amplifier stages connected in cascade, to produce an amplified output A.C. voltage which is applied to the other input of the differential amplifier as a negative feedback voltage, via a series chain of resistors and a selector switch which determines the A.C. feedback level. Transistors T2, T3 are connected as a long-tailed pair, the base of transistor T2 being driven with A.C. signal via level-setting potentiometer R1, capacitor C1, and emitterfollower T1. The collector of transistor T2 is D.C. coupled to a D.C. coupled amplifier comprising emitter-follower T5 followed by common-emitter stages T6, T7. The output from transistor T7 is taken to an output terminal via emitter-follower T10 and capacitor C8, and via a second emitter-follower T9 to a seriesconnected chain of resistors R26-R31. Switch Sl selects an output from a tapping point on resistors R26-R31 and applies it via capacitor C3 and emitter follower T4 to the base of transistor T3.
