IPC: B60D1/06
Filed: 1970-12-23
Abstract: 1314849 Ball-and-socket trailer couplings K J BERNDES 23 Dec 1970 [24 Dec 1969] 61186/70 Heading B7T A ball-and-socket trailer coupling comprises a housing 1 having its front end shaped to form a first part of the socket and pivoted thereto on a pin 5 a second socket part 3 movable between a ball retaining position and a ball released position by a handle 6, handle parts 46, extending into the housing and being formed with slots 14 which retain a pin 15 also movable in slots 17 of the housing, and the pin 15 in the material such as P.V.C.-coated nylon fabric and comprises: a cover portion 1 in the shape of a box having a rectangular base part 2 and sides 3a, 3b, 3c and 3d extending therefrom, intended for use with the base part 2 uppermost ; a flap 4 forming an extension of one side 3d; means 11, 12 adapted to attach the flap 4 to the base of the luggage rack; and means 16, 17 attached to the cover portion 2 adapted to secure the cover portion in position over the articles on the rack and simultaneously secure the articles on the rack. The flap 4 extends from side 3d which in use faces the front of the vehicle, and has a channel 5 formed in its outer end to receive an elongated elastic member 11 having a hook 12 at each end adapted to engage opposite lower members of the rack. Reinforcing strips 13 and 14 are attached along the diagonals of the base part 2 and have rings 15 at their ends to which are attached elongated elastic members 16 carrying hooks 17 adapted to engage the rack. Eyelets 18 are provided ' along the lower edges of the sides 3a, 3b and 3c so that they may be roped to the rack if required. The elastic members 11 and 16 are preferably formed of stranded rubber covered with an abrasion resistor cover. Joints in the cover portion may be formed by stitching or welding. ball retaining position of the socket part 3 engaging the edges 24 of lugs 4, which extend rewardly from part 3, and being biased to said engaging position by a spring 18 mounted on a pivot 9 by which the handle is mounted on the housing. To release a ball from the socket the handle is moved vertically upwards utilizing the slots 14 and 10 through which the pin 15 and pivot 9 extend and then pivoted anticlockwise about pivot 9 so that pin 15 is released from engagement with edges 24 and the socket part 3 can pivot about pin 5 under the action of spring 2. If the handle is then released the pin 15 will engage edges 34 of the lugs 4 thus locking the socket part 3 in its ball released position. Projections 56 on the handle prevent pivoting of the latter until it has been raised. A U-section member 7 riveted to housing 1 forms the end bearings for pivot 9.

Patent GB-664400-A (GB)
IPC: H02M1/04
Abstract: 664,400. Converting. BERTELE, H. C., and NEVELIN ELECTRIC CO., Ltd. Feb. 28, 1949 [Jan. 26, 1948], No. 2345/48. Class 38 (ii). A grid-control circuit for an arc rectifier comprises a saturable transformer for each of at least some of the grids to produce a voltage pulse having a steep voltage-time characteristic, the D.C. saturating current and the grid bias being derived from one or more existing D.C. excitation circuits, comprising one or more excitation circuits energized through the rectifier or, when a D.C. motor is associated with the rectifier, the motor field excitation circuit. Fig. 1 shows a 3-phase mercury arc rectifier 12, each grid 14 of which is connected to the secondary winding 16 of its respective saturable transformer 17. The latter has two primaries 19, 27 supplied with A.C. and D.C. respectively. This A.C. is supplied from a secondary 21 of a 3-phase transformer the primary (not shown) of which is connected to the anode supply, hence the current in the winding 19 is in phase with the corresponding anode current, but this phase relationship can be varied by altering the value of resistor 26. The phase of the induced gradient voltage pulse in the secondary 16 is varied according to the degree of saturation in dependence upon the value of the saturation current in the winding 27. The saturating current and the biasing potential are obtained from tappings on a resistor 28 inserted in the rectifier D.C. auxiliary circuit 29. Each primary winding 19 forms part of an associated resonant circuit 20 tuned to the supply frequency. Fig. 2 shows an arrangement by which the exciting current to the primary winding 19 can be supplied from either a star or delta connected transformer according to the position of a switch 37 ; thus the position of the switch 37 on to the condenser 39 side is used for a delta connection. By connecting the terminals 40, 41 to a D.C. supply a further control of the phase of the grid-control pulses from the transformers 17 may be effected and also the rectifier output may be automatically controlled. Specifications 648,454, [Group XL (a)], and 664,408 are referred to.
Patent GB-672771-A (GB)
Abstract: 672,771. Calculating-apparatus. OLIVETTI & CIE. SOC. ANON., C. Dec. 30, 1947 [Aug. 26, 1944], No 34867/47. Class 106 (i). A multiplying mechanism for an adding and subtracting machine having a stop carriage and a supplementary keyboard on which the digits of the multiplier may be set in turn, is characterized in that operation of one of the multiplier keys " 6 " to " 9 " causes the machine to carry out a complementary number of subtraction cycles to effect a displacement of the stop carriage to the next higher order, and to carry out a subsequent addition cycle. The multiplier keys, Fig. 2, are arranged in two adjacent rows and depression of any one moves a slide 3, Fig. 3, which has cam slots to co-operate with pins in the key-stems. At the same time the key depresses the appropriate one of five spring bars 4 which correspond with the five complementary pairs of keys and are mounted in a slidable frame 12. The bar 4 rocks a yoke 5 which through a slide 6, rocks a lever 7 to lock the key-operated slide 3 and to move a link 8 which causes the machine-drive to operate. At each cycle, a pawl 11 on a rotating arm advances a rack 9, which co-operates with a pawl 10, by one step, until an abutment on the rack engages the depressed bar 4 and slides the frame 12 against a spring until the bar is moved from beneath the depressed key-stem and restored by its spring. The machine is normally conditioned for addition. If the depressed key was one of the keys "1" to " 5," the yoke 5, slide 6 and lever 7 are also restored so that the slide 3 and depressed key are released and the link 8 is free to be restored at the end of the cycle to stop the machine. A link 22 is also restored to move the stop carriage to the next higher denomination. However, if one of the keys " 6 "-" 9 " is depressed, a yoke 21, Fig. 4, is also rocked and, through a bar 13 and lever 14, shifts a link 15 which conditions the machine for subtraction. The lever 14 also causes an arm 17 to engage behind a pin in the starting link 8, in which latching position it is locked by a sprung lever 18. When the slide 12 is moved by the rack 9, the bar 13 is rocked and disengaged from a pin in the yoke 21 to allow the lever 14 to be restored so that the machine is conditioned for addition again. By virtue of the latch 17 the machine continues to operate for a further cycle after the link 22, Fig. 3, has moved the stop carriage to the next higher denomination and during this cycle, a cam 19 rocks the lever 18 to release the latch 17 and allow the link 8 to be restored to stop the machine. If the zero key is depressed, known mechanism merely causes a shift of the stop carriage.

Title: Safety Device for Fastening Machine
IPC: F16P3/16
Filed: 1978-12-20
Abstract: The invention provides a safety device for a fastening machine such as a stapling machine which prevents ejection of a staple if an operator's hand or finger is present between the stapling head and the anvil during a stapling operation. The safety device comprises a blocking piece 40 normally maintained between the relatively movable hammer frame 13 and the staple carrier 14 of the stapling head 12.
