Title: A new or improved latch for divided articles
Inventor: WHYSALL WILLIAM ARTHUR
IPC: A45D8/34
Filed: 1954-01-11
Abstract: 752,216. Combs; hair slides. NEWEY BROS., Ltd. Oct. 13, 1954 [Jan. 11, 1954], No. 699/54. Class 131. [Also in Group XXV] A ring comb for hair is formed by two partrings 10, 11 hinged together at one end of each and at the other end latched together by cooperating teeth which are released by urging those ends apart by a relative movement in a radial direction with respect to the centre of the ring and includes means for preventing relative movement in a direction parallel to the axis of the ring. As shown the free end of each partring is formed with two teeth 14, 15 and 16, 17 and each pair of teeth is staggered circumferentially to prevent the movement parallel to the ring axis. The teeth are formed by notching each end of the ring and lateral displacement in one direction is prevented by the inside face of tooth 17 abutting against a face 19 at the rear of the notch which receives the tooth 16. Lateral displacement in the other direction is prevented by the abutment of the inner face of the tooth 14 against a face (not shown) at the rear of the notch which receives the tooth 15. The latch is disengaged by pressing the part ring 10 inwardly and a projection 21 is provided on its outer face at the position where pressure should be applied. In a modification there may be only one pair of co-operating teeth extending for part of the width of the part-rings 10,11 the other pair of teeth being replaced by complementary stepped ledges of which the part remote from the free end of each part-ring projects beyond the notch of the teeth on that member. Specification 731,764 is referred to.

Title: Improvements in Automatic Telephone Systems.
IPC: H04M3/12
Filed: 1917-01-16
Abstract: 112,650. Relay Automatic Telephone Co., and Johnson, B. B. Jan. 15, 1917. Exchange systems.-The character of a line that is faulty is automatically changed so that when called it switches the calling line to another line, which may be that of an exchange attendant. If the faulty line is called by an operator offering a preferred call, an out-of-order tone may be given to the operator. When a line S becomes faulty, its line relay L is energized and causes one of the switching-relays C1, C2 to connect it to an idle junction line, as described in Specification 9840/14, the relay, C2 say, looking up in a circuit 5 including the cut-off relay CO and an additional relay F. The impulse relay IR of the selected junction is energized over the faulty line, and, after an interval determined by a timing- device TS, opens circuit 5. The relay F, being slow to de-energize, locks up over a circuit 6 including the faulty line, but the cut-off relay CO is de-energized. In a normal call, a set of selecting-impulses quickly follows the extension of the line to the relay IR, and a relay R is arranged to open-circuit the timing-device TS and to extend the circuit 5 to the next digit stage. When a line S in normal condition is called, one of the relays C1, C2, &c. is energized over circuit 7 and locks up in known manner over circuits 5 including relays CO and F. When a faulty line is called, (its relay F being energized), the circuit 7 is extended over branch 10 to the relays CL, CLI &c. of the attendant's circuit O, to which the calling-line is connected. If this attendant's line is busy, the relays F2, CO2 will be energized and the circuit 10 will be extended over lead 13 to an attendant's auxiliary line. An operator handling a preferred call makes connexion to the junction P and can release a local connexion by earthing the lead 51. If the wanted line is faulty, an out-of-order signal is given over circuit 14 to the operator. If the junction P ends in a jack at the operator's position, the circuit 14 may be connected over circuit 51 to the bush of the jack.

Title: Improvements relating to multiple filters
IPC: B01D35/12
Filed: 1946-01-09
Abstract: 610,075. Filters. TECALEMIT, Ltd., and LE CLAIR, C. C. S. Jan. 9, 1946, No. 853. [Class 46] A multiple filter assembly comprises a head with a main liquid inlet chamber and a main outlet chamber, and three or more filters carried by the head, each filter having its own inlet and outlet and having a filter element in a detachable container, a rotary control valve being provided which is operable from the outside of the assembly whereby one or more filters in turn can be cut off from communication with the main inlet and outlet chambers by rotation of the valve in one direction. In the assembly shown, four filters are suspended from a head comprising a carrier 5 to which containers with filter elements 6 are detachably secured, a valve plate 7, and a valve cover 8, the three parts being connected by bolts 100. The valve cover 8 has an inlet chamber 40 separated from an outlet chamber 41 by a partition 39 which has a circular opening in which is fitted a rotary control valve 34. The valve is operated by means of a hand-wheel 55 secured to a ratchet-base 56 which cooperates with a pawl 59 on the valve cover. The valve plate 7 is formed with four inlet ports and four outlet ports, one of each for each filter unit. The valve 34 has an inlet port 49 and an outlet port 48, each rotating over an angle of approximately 270 degrees so that they communicate normally with three of the four filters, communication with the remaining filter being masked by a blank port 52 of the valve. In the face of the valve there is a small venting port 53 communicating with atmosphere through an axial duct in the valve spindle 43. The container of each filter element is held in place by a bolt 11 fitted at the top with a hand knob 16. Each knob has flattened corners 62 disposed relatively to the ratchet disc 56 so that the knobs of three of the filters are prevented from rotation, only the knob of that filter which is isolated from the liquid supply system being free to rotate, due to the provision of a segmental notch 63 in the disc. In operation, assuming that filter No. 1 has been removed, cleaned and replaced, the hand wheel 55 is turned through an angle of 45 degrees. This permits air to be vented through the spindle 43 and also brings this filter into communication with the outlet chamber 41. Oil flows back into the filter and expels the air. The handwheel is again turned through 45 degrees, allowing the inlet chamber 40 to communicate with the filter which is now completely included in the supply system while the next filter No. 4 is isolated, and can be removed.
