Title: Circuits for controlling the energisation of brake anti-locking control systems of towing vehicles
IPC: B60T8/00
Filed: 1973-09-07
Abstract: 1439384 Anti-locking control systems; warning devices ROBERT BOSCH GmbH 7 Sept 1973 [11 Sept 1972] 42206/73 Headings F2F and F2E A towing vehicle having an anti-locking control system 13 comprises a plug 20 connectible to a socket 21 of a trailer for connecting the electrical supply system of the towing vehicle to the electrical system of the trailer; depending on whether the trailer also has an anti-locking control system or not the socket 21 will respectively hold the anti-locking system 13 in an activated state or bring it to a deactivated state. As shown in Fig. 1, the anti-locking control system 13 is connectible to a battery 10 by a switch 12 which is part of a control relay 11; the control relay 11 also includes a solenoid 14 one terminal of which is connectible by an ignition switch 15 to the battery 10 and the other terminal of which is connected to a contact 27 of the plug 20 and to earth via a control switch 29. A brake light switch 17 is connected to the junction between the ignition switch 15 and the solenoid 14 and also connects with brake lights 18, 19 and with trailer brake lights 40, 41 via contacts 24, 34 in the plug and socket 20, 21 respectively. A control lamp 39 is connected between the brake lights 18, 19. Current is only supplied to the anti-locking control system 13 of the towing vehicle when the switch 12 is closed by energization of the solenoid 14 and such energization is only possible when the other contact of the solenoid 14 is connected to earth. In the case of the towing vehicle being operated without a trailer the solenoid 14 has an earth connection by way of the control switch 29, which is a normally closed pushbutton switch. In the case of the towing vehicle being operated with a trailer with an anti-locking control system (see Fig. 1) the control switch 29 is opened by the housing 31 of the trailer socket 21 but the solenoid 14 still has an earth connection via the contact 27 and an earthed contact 37 of socket 21. In the case of the towing vehicle being operated with a trailer without an anti-locking control system (not shown) the contact 37 is not earthed and thus interconnection of plug and socket 20, 21 will terminate any earth connection to solenoid 14 and deactivate the anti-locking control system 13. The control lamp 39 provides an indication as to whether the anti-locking control system 13 is working or not. In the embodiment of Fig. 2 the brake light switch 17 is connected to the contact 24 by way of a solenoid 43 of a current relay 42, which solenoid 43 is energizable to open a switch 44 between the solenoid 14 and earth. In the case of operation of the towing vehicle with a trailer not having an anti-locking control system, actuation of the brakes will close switch 17, energize solenoid 43 and open switch 44 to break the earth connection of the solenoid 14.

Title: Dung removers
IPC: B08B1/00
Filed: 1972-09-20
Abstract: 1396360 Dung remover ALFA LAVAL AB 20 Sept 1972 [14 Oct 1971] 43558/72 Heading A1M A dung remover comprises scrapers 5 located in a dung channel 1 and hingedly connected to a pivot 6 connected to a guide piece 4, of U shaped cross-section, moved intermittently in the direction of its longitudinal axis by a bar 7 within a groove 3. Movement in the operating direction, arrow A, swings the scrapers 5 away from each other to extend across the width of the dung channel 1, while the reverse movement causes them to converge at the central groove 3. The guide piece 4 is moved incrementally by reciprocating motion of the bar 7. Motion of the bar 7 in a direction C results in a roller 17 carried by the guide piece moving up a cam face 14 formed in a clamp body 10 to lock guide piece 4 to the bar 7 so that guide piece 4 and pivot 6 move with the bar 7. When the bar 7 moves in the direction of an arrow D, the roller 17 moves down the cam face 14 freeing the guide piece 4 from the bar 7. The direction of travel of the scrapers is reversed when the guide piece 4 reaches a stop 23 and further movement in the direction of arrow C is prevented. Movement of the bar 7 in the same direction forces the roller 17 over to the cam slope 15. Further reciprocating action of the bar 7 results in the guide piece 4 moving incrementally in the direction of arrow D. An alternative embodiment shown in Fig. 5, positions the guide piece 4 with respect to the roller 17 by plate springs 24. The clamping action resulting from relative movement between the roller 17 and the body 11 is accentuated by the raising of the guide piece 4 as the plate springs 24 deflect. The action of the plate springs 24 results in easier loosening of the clamping forces on reversal of the direction of motion of the bar 7.

Abstract: 1,260,608. Printing apparatus. EASTMAN KODAK CO. 11 Sept., 1970 [26 Sept., 1969], No. 43681/70. Heading B6C. Apparatus for printing indicia on documents such as cheques comprises means for conveying the documents past a printing device and a member which, in response to the passage of a document to the printing position, is moved from an inoperative position to a position where it backs up or supports the document as it is being printed. In one embodiment, Fig. 3A, the documents are fed to the printing position 49 by laterally-spaced pairs of belts 23, 25 passing over driven pulleys 19. Between the pairs of belts is mounted, on a support 54, a resilient member 52 having a rounded end 51 projecting into the path of the documents. When a document reaches the member 52 it bends the end 51 upwardly so that the end 51 supports the document and presses a part of it radially outward into engagement with a printing roller 38 spaced from the normal path of the document thereby causing rotation of the roller so that characters 42 are printed on the document. Screw-stops 58, 60 limit the movement of the member 52. After the document has passed the printing position, the member 52 springs back to its original position. In other embodiments (Figs. 4 to 7), a roller, whose axle is movable in slots in fixed supports, normally occupies a position corresponding to the inoperative position of the end 51 under the action of gravity or a spring. When the leading edge of a document engages the roller, the roller is moved to the printing position to support the document in the same manner as the end 51. According to another construction, Fig. 8, the document in its movement deflects fingers 354, 355 on a member 352 to the positions shown dotted. During such deflection, a central finger 358 engages a stop 356 which causes the finger to be deflected to the dotted line position where it presses a part of the document against the printing roller.
