Inventor: ARNOLD HAROLD JAMES
IPC: E05F3/10
Filed: 1918-12-14
Abstract: 127,506. Arnold, H. J. Dec. 14, 1918. Operating doors by springs; checks. - A spring hinge for swing doors &c. comprises a primary spring - pressed sliding plate co-operating with a cam on the hinge spindle, and a secondary spring-pressed sliding plate arranged to exert additional pressure on the primary sliding plate for the first few degrees of movement of the spindle and when the opening movement approaches ninety degrees. The secondary sliding plate is actuated in the first instance by members pivoted on the primary sliding plate ; these pivoted members form a check to the return movement of the primary sliding plate, which may also be provided with an hydraulic, pneumatic, or dash-pot device. Provision is also made for adjusting the hinge spindle in relation to the door. Fig. 4 shows the position of the parts when the hinge spindle has rotated about ninety degrees. The primary sliding plate 6 co-operates with a cam 4 on the hinge spindle 2 and with a spring 8. The end 7 of the plate 6 is shaped to surround the cam 4 and so avoid lost motion on reversal of the door movement. The secondary sliding plate 17 cn-operates with springs 18 and with bell-crank levers 10 pivoted at 11 nn the plate 6. The outer ends 12 of the levers 10 travel along a channel 13 formed between the end of the casing 1 and a projection 14 on the bottom of the casing. The inner ends 15 of the levers 10 are in sliding contact with the outer end of the plate 17, which is shaped so that, after a short inward movement of the plate, the levers 10 cease to advance the plate and act for a time as struts between the end of the casing and the plate. Towards the end of the inward movement of the plate 6, shoulders 19 on this plate engage with stop-screws 21 in projections 20 on the plate 17. If the movement is continued beyond ninety degrees, the cam 4 reaches a dead-centre position in which it acts to hold the door open. The levers 10 check the return movement; also the plate 6 is provided with a dash-pot device 25. Fig. 5 shows the means for adjusting the hinge spindle in relation to the door. An arm 26 on the hinge spindle 2 is provided at its free end with two tapped holes receiving adjusting-screws 30 passing through plates 29 attached to the door.

Patent GB-642576-A (GB)
Title: Improvements in or relating to high frequency electric cables
Inventor: BAGULEY ERIC
IPC: H02G15/08
Filed: 1948-08-09
Abstract: 642,576. Sleeve couplings. STANDARD TELEPHONES & CABLES, Ltd. Aug. 9, 1948, No. 20926. Addition to 642,540, [Group XL (b)] [Class 38 (i)] [Also in Group XL (b)] The components of each of several similar joints in a coaxial or balanced pair cable approximate to those of a reflectionless joint according to the parent Specification so that the vector sum of the reflections from all the joints in the cable is zero. Two coaxial cables 1, 2 to be joined, have cylindrical polythene spacers 5 closed at one end, and are cut so that the distance between each cable end and the centre line A-A of the joint is equal to half the length of a spacer 5, and the equal incomplete spacers 7, 8 are greater than half a spacer. The first few spacers are removed from the cables and steel collars 12 slipped over the ends. The outer conductors 4 and steel tape binding 6 of cables 1, 2 are soldered to shouldered collar 10 and threaded collar 11 respectively, and the ends of the outer conductors soldered to copper rings 9. A copper ring 15 carrying a small rubber ring 16 is soldered into the ends of the inner conductors 3. The polythene spacers are replaced and a split joint spacer 17 placed with flanges overlapping the ends of the incomplete spacers 7, 8. The joint spacer 17 is designed to give a reflectionless joint according to the parent Specification when the incomplete spacers 7, 8 are exactly equal to three-quarters of a spacer. Since the incomplete spacers at each joint are between one half and a whole spacer, the average size is three-quarters of a spacer and hence the reflections caused by variations from this size cancel out over a complete length of cable. The joint spacer 17 is bound round the rubber ring 16 which forms a seal between it and the inner conductors. A rubber ring 13, previously slipped on to cable 1, is rolled into the central groove of the spacer and a layer of heat insulating tape bound round the last two spacers on either side. A sheet of copper foil 20 is soldered round the joint and to the copper rings 9. The rubber ring 13, which protects the spacer 17 from damage during the soldering, is compressed by a copper wire binding 21 and seals the spacer 17 to the outer conductor. A steel sleeve 14 previously slipped on cable 2 is screwed over the collar 11 until the opposite end engages the shoulder of collar 10, and the collars 12 are screwed to each end.
