Title: Method and apparatus for the transfer of persons and articles in marine situations
IPC: B66C13/02
Filed: 1973-11-21
Abstract: 1411490 Transferring loading to boats; stress limiting R A BEGAULT 21 Nov 1973 [22 Nov 1972] 53942/73 Headings B8E and B8B Transfer apparatus for lowering a cage 12 with its load from a fixed platform, by a crane cable 17 to a boat 11 comprises a piston cylinder device 21 in a closed pneumatic circuit inserted between the cage 12 and the crane cable 17 a deadline 22 being attached below the cage. From the rest platform position, Fig. 2, after loading the cage 12 a valve 14, Fig. 5, is opened thus venting the system and allowing the crane cable 17 to extend the piston rod 19. Closure of the valve 14 and locking of the cable 17 allows on re-opening of the valve a pressure source through connector 13 to pressurize the reservoirs 26 and cylinder 21 thus retracting the rod 19 to raise the cage 12 from the platform. The crane then positions the cage at ¢-wave height above the boat and the deadline 22 is connected to a boat winch 25 which draws the cage on to the boat deck against the cushioning effect of increased pressure in the cylinder 21 and holds it there for unloading. If a larger return load is loaded the system may require greater pressurization by connecting through the connectors 13 to a source of pressure in the boat. To prevent a dangerous sudden rise of the cage if the deadline restraining force suddenly fails a poppet valve is inserted in circuit to the vents of the lower end of the cylinder 21 which valve on failure closes to restrict the vents and thus the raising speed of the cylinder by spring pressure normally overcome by the pull of the deadline 22.

Filed: 1973-11-26
Abstract: 1441128 Selective signalling INTERNATIONAL BUSINESS MACHINES CORP 26 Nov 1973 [29 Dec 1972] 54761/73 Heading G4H [Also in Division H4] A data handling system incorporates an interconnected plurality of units and a polling mechanism for the system including control logic in each unit, such control logic being connected to a deselect line and being formed into a closed sequential loop by a select line, poll control being offered by raising the select line to the next sequential control logic in the loop and accepted by raising the deselect line. If a unit does not require poll control when the raised state of the select line reaches it, it simply passes this raised state on to the next unit in the loop. If it does require poll control it raises the deselect line which causes the offering unit to drop the select line and this causes the accepting unit to drop the deselect line. A unit can request poll control from whichever unit has it by raising a (common) polling request line, or a (common) urgent polling request line. The latter will cause granting of the request even if the unit having poll control needs it itself, assuming this need is not itself urgent. The unit having poll control can perform data transfer. Use of the urgent polling request line permits data transfer by high speed devices to have priority over low speed data transfers, control transfers and input/output interrupts.

Title: Labelling machine
IPC: B65C9/44
Filed: 1965-12-24
Abstract: 1,114,860. Labelling-machines. EUREKA-CARLISLE CO. 24 Dec., 1965 [24 Dec., 1964], No. 54788/65. Heading B8F. In a labelling machine labels with conductive markings (290, Fig. 6, not shown) are discarded, the feed of articles to which the labels are attached, being temporarily stopped. In the machine described, the markings are sensed by probes connected to a relay circuit which controls the operation of one-revolution clutches driving the feeds for the labels and articles. A second form of marking (291) stops both feeds. Feeding the articles.-Envelopes or similar articles are fed from the bottom of a stack SA (Fig. 1) by belts 52, 53 which deliver them to rollers (63) (Fig. 3, not shown) co-operating with adjustable circular members (79) of abrasive stone which prevent more than one article being fed at a time. The stack is carried between adjustable plates 48 (Fig. 1) and a table 26 which can be adjusted laterally on the labelling machine. Feeding, cutting and attaching the labels.- The labels L (Fig. 1) are fed to the labelling position by reciprocating members (126), (127) (Fig. 2, not shown), which engage perforations (P) (Fig. 6, not shown) in the strip of labels and are reciprocated by an arm (122) (Fig. 2, not shown) from a barrel cam (124). After passing the sensing head 92 (Fig. 1), the labels are cut off by a guillotine (164) (Fig. 3A, not shown) which carries a roller (168) pressing the label on to the envelope. If feed of an article has been prevented, the label is pressed by the roller (168) against a driven roller 170 which feeds it to a discard hopper. An article-sensing switch (251) (Fig. 3A, not shown) prevents feed of a second label while an unusually long article is being fed. Wetting labels.-The labels are pre-gummed, and the articles are wetted through jets (172) (Fig. 3A, not shown) fed with water from a reservoir 173 (Fig. 1) by a solenoid-operated pump 184 whose timing can be altered to alter the region of the article which is sprayed. Testing.-The label feed and the article feed can be operated independently by manual controls.

Title: Bi-stable trigger circuit
IPC: H03K3/26
Filed: 1967-12-14
Abstract: 1,213,979. Bi-stable circuits. NIPPON ELECTRIC CO. Ltd. 14 Dec., 1967 [24 Dec., 1966], No. 56881/67. Heading H3T. Two bi-stable circuits connected in cascade are operated 180 degrees out of phase, each bistable circuit being of the cross-coupled amplifier type and having a setting phase during which current is diverted from a holding path to a setting path. The fig. shows two bi-stable circuits 101, 102 comprising two main transistors 3, cross-coupled through emitter followers 5, 6. On the occurrence of a clock pulse at 62 current is diverted from transistor 22 feeding the main transistors to transistor 21 feeding auxiliary transistors 1 and 2. The information input at 61 steers the current to one or other .of the auxiliary transistors and sets the condition of emitter followers 5 and 6 so that at the end of the clock pulse the emitter followers are held in this state. An -emitter follower transistor 43 provides a fixed reference bias for the base of transistor 2 and through a transistor 44 strapped as a diode provides a slightly less reference voltage to the bases of transistors 22 and 31. The bi-stable circuit 102 receives its input at terminals 83, 84 from the output 75, 76 of 101 and has a constant current transistor 33 in the supply lead. The clock pulses are so connected to the current-diverting transistors of the two bi-stable circuits as to render them responsive to input signals in opposite phases whereby the signal is first entered into the bi-stable circuit 101 and then in the next half cycle of the clock pulses is transferred to bi-stable circuit 102. The output from the second circuit is therefore available with one clock period delay.
