Patent GB-798185-A (GB)
Title: Improvements relating to transformer tap-change systems
Inventor: BRIERLEY RALPH
IPC: H01F29/04
Filed: 1954-10-30
Abstract: 798,185. Transformer arrangements. FERRANTI, Ltd. Jan. 27, 1956 [Oct. 30, 1954], No. 31409/54. Class 38 (4). A transformer tap-changing system for the parallel operation of a number of transformers includes a number of switches so associated with the taps on the transformers and so interconnected that when a tap change of one transformer has been completed, a tap change on the next transformer begins and when this is completed a tap change on the next transformer begins and so on until all the transformers have undergone a tap changing operation. Closure of a " raise " push-button 22 in a control unit 10 energizes a raise contactor winding 13 to operate a bank of mercury switches (not shown) which control the motor which drives the tap changing gear. Assuming the tapping position of the transformers from which a change is to take place to be an " even " numbered one, the even " switches 28, 35 will be closed and the odd " switches 25, 34 will be opened. Under such conditions the energizing circuit between the bus-bar 19 and neutral 20 is by way of switch 18, push-button 22, switch 37 in a control unit 24, " even " switch 35 in this unit and " even " switch 28 in the unit 10. The switches are self-maintaining so that when the tap change motor has begun to operate the pushbutton 22 can be released. Shortly after the motor has begun to rotate switch 17 is closed and switches 18, 37 opened. Towards the end of the tap-change operation on the transformer associated with the unit 10 the switch 36 therein closes and the " even " switch 35 opens whilst the " odd " switch 34 closes. The raise contactor winding 13 in the unit 33 now becomes energized and a tap-change operation is carried out on the transformer associated with that unit, the tap-change operations on the succeeding transformers being similarly controlled. If for some reason any control unit fails to respond an appropriate alarm device 32 will be energized. A device 32 will also give an indication of a short-circuit in the connections between its " odd " and " even " switches and those in a preceding control unit. The switch 37 in the last control unit 24 ensures that a further tap change cannot be initiated in the unit 10 until the unit 24 has completed its previous tap change. The lower contactor winding 12 is energized by means of pushbutton 21.

Title: Improvements in or relating to knitting machines of the circular, independent needle, type
IPC: D04B9/32
Filed: 1945-11-22
Abstract: 605,494. Knitting-machines. HEMPHILL CO. Nov. 22, 1945, No. 31507. Convention date, Nov. 23, 1944. [Class 74(ii)] Two oppositely directed wrap horns, 8, 9, for facilitating the introduction of a wrap yarn to selected elevated needles, are positioned at the auxiliary side of a circular machine adjacent the backs of the independently operable needles and are adapted to move, one to an inoperative and the other to an operative position during each movement of reciprocatory knitting to permit wrap yarns to be knitted in both directions of knitting. As described the wrap horns 8, 9, are provided at their ends with rollers 10 slidable in guides 11 on brackets 12 mounted on a segment 13, which is adapted to partly rotate on a guide ring 14 attached to the carrier plate 3. Rotation of the segment 13 is controlled through a finger 21 by a ring 15, frictionally driven by the sinker head 16, the movement of the sinker head with the needle cylinder in either direction imparting a corresponding movement to the wrap horns. The movement of the wrap horns is limited by a stop member 19 on the ring 15 engaging a stationary member 20. A pin 26 extending from the rollers 10 on the ends of the wrap horns engages a slot 24, 25, in a plate 23 mounted on carrier plate 3 so that as the horns are rotated they are raised and lowered to an inoperative and operative position, one wrap horn being raised and one lowered in each direction of movement. Specifications 600,921 and 601,056 are referred to.

Patent GB-522003-A (GB)
Title: Improvements in or relating to devices for the automatic control of change speed gears for motor vehicles
Filed: 1938-11-02
Abstract: 522,003. Controlling variable-speed gears. NOUGAROU, J. Nov. 2, 1938, No. 31746. Convention date, Nov. 3, 1937. [Class 80 (ii)] A device for the automatic control of changespeed gears for motor vehicles has the change initiated by the closing of an electrical contact effected in consequence of the reciprocal parallel movement of two members, the movement of one of these members is dependent on the speed of the vehicle and the other member has a lostmotion connection with the accelerator. In the arrangement shown in Fig. 1 a contact 65 moved by means responsive to the speed of the vehicle co-operates with two spring contacts 2, 3 carried by a member 69 mounted on a plunger 9 slidably mounted in a cylinder 90. Collars 13, 14 adjustably mounted on the inner cable 17 of a Bowden wire 16 provide a lost-motion connection between the member 69 and the accelerator pedal. Adjustable stops 11, 12 on a member 10 cooperate with a lug 91 to limit the movement of the member 69. When the accelerator is in the slow running position a stop 18 on the cable 17 retreats and allows spring contact 20 to engage contact 19 and so short-circuiting contacts and preventing automatic gear change. While the contact 65 is in contact with both the contacts 2, 3 both the coils 4, 5 of a relay are energized and the movable contact 21 remains in engagement with that one of the contacts 6, 7 with which it was in engagement when a single coil was last energized. In the event of the contact moving in the direction necessary to break the circuit including this coil the switch swings over and a gear change is initiated. In a modification for controlling a four-speed gear the circuit includes six contacts, adapted to co-operate with the contact 65, two relays similar to the relay 4, 5, 6, 7 and four single contact relays one of which has a double winding and another of which is slowacting the armature carrying a plate positioned in a viscous liquid in proximity to a fixed plate.

Filed: 1964-08-05
Abstract: An explosive composition comprising ammonium nitrate sensitized by phenol-formaldehyde resin is prepared by mixing particulate ammonium nitrate with a phenol and a source of formaldehyde, condensing the phenol and formaldehyde, and drying off the water produced. Condensation is accelerated by heating to 50-70 DEG  C.  The mixture may include a condensation accelerator, e.g. p-toluene sulphonic acid, or an inhibitor, e.g. urea, magnesium oxide, or diammonium phosphate. Paraformaldehyde is used as the source of formaldehyde, and the other component of the resin may be phenol, resorcinol, or o-cresol. The ammonium nitrate may be coated with the sodium or ammonium salt of methylene bismonomethyl naphthalene monosulphonic acid as a surface active agent.  In examples the components are mixed dry and condensed at room temperature or 55 DEG  C.; in one example a small amount of potassium nitrate is added. The composition is useful as a blasting agent and may be detonated by PETN or a mixture of mercury fulminate and potassium chlorate.
