Abstract: 1,090,701. Waveguide couplings. PORTCHESTER INSTRUMENT CORPORATION. Sept. 6, 1965 [Jan. 21, 1965], No. 37997/65. Heading H1W. A waveguide solderless coupling comprises a loose collar 10 and a coupling element 20 both fitting snugly over a rectangular waveguide 30. The loose collar 10 is secured to the waveguide by means of grub screws threaded into holes 11 and the element 20 is secured to the loose collar by pins 14 extending into threaded holes 12, 26. A sealing 0-ring 15, e.g. of silicone rubber, is interposed between the two elements. As shown, element 20 is a coupling flange and is provided with choke slots 35, 36.

[Class 39 (ii).] An electric battery lamp adapted for use as a cycle lamp, with a reflector 3 mounted in a cover ring 2 at the front of the casing 1 and a battery 7 mounted in the casing with its pole lugs directed to the side walls, is provided with at least one contact spring which bears against a pole lug of the battery as is directed towards the wall of the casing lying opposite the cover ring, thereby facilitating the insertion and withdrawal of the battery and enabling a good contact to be obtained. In the example a two-armed contact spring 4, 5 is secured to the side wall of the casing, with one arm 4 extending rearwardly into contact with a pole lug 6 of the battery while the other arm 5 bears upon the hollow reflector 3 and provides a connection to the lamp. The other pole lug of the battery bears against a contact spring which is mounted upon a switch plate on the rear wall of the casing and is bent reversely towards the rear wall. The battery is secured in position by the lateral portions 13, 14 of a resilient metal strip 12 secured to the rear wall of the casing. The Specification as open to inspection under Sect. 91 (3) (a) describes also the formation of a cable clip or lug at the end of the hinge bolt which connects the cover ring to the casing, so that a cable passing therethrough from the lamp holder mounted in the reflector to a terminal on the rear wall of the casing may be looped to enable the cover ring to be opened freely. This subject-matter does not appear in the Specification as accepted.

In the embodiment of Fig. 1 the output of buffer store 128 and an input buffer 123 are applied to readonly store 126 under the control of a clock pulse CP1. The data read from store 126 is fed to buffer 127 from which it is read out by a clock pulse CP2 (delayed with respect to clock pulse CP1) to both buffer store 128 and to a decoder 129 to provide the output signal for the circuit. The read-only stores which are programmable are unpluggable so that the sequence may be changed or a different language used. Additional read-only stores may be introduced (Fig. 5, not shown) to cope with a larger number of inputs. In a further embodiment (Fig. 6, not shown) with a faster response time, the feedback signal from the buffer store is applied in parallel to the read-only stores. In a further embodiment (Fig. 7, not shown) which accepts up to 16 input variables and has 4 read-only stores and 2 decoders each providing an output signal, each decoder provides feedback to one of the read-only stores associated with the other decoder.

Patent GB-397779-A (GB)
Abstract: 397,779. Holding tickets and tokens. LANDIS & GYR AKT.-GES., 1, Hofstrasse, Zug, Switzerland. Feb. 28, 1933, No. 6070. Convention date, March 29, 1932. [Class 106 (iii).] In a magazine for strips of tickets, vouchers, &c. stacked in a reserve compartment in a ticket issuing apparatus, means are provided to facilitate the introduction of a fresh pile. The magazine, arranged in the lower part of the casing 1, contains a strip of tickets &c. arranged zig-zag fashion in a pile between a plate 10 pressed upwards by a spring 11 and end rollers 7 carried by the casing. The tickets are led upwards between rollers 8 carried on spring levers 9. The plate 10 is guided vertically by pins 12 working in slots 13 in the sides of a U-shaped frame 5. When replenishing, the plate 10 is lowered, but the remainder of the pile is held up by projections 20 while the fresh pile is inserted, the ends of the two piles being stuck together before the plate 10 is again pressed up by its spring. The plate 10 is lowered by moving to the left a slide 24 surrounding the frame 5 and having on each side guideways 25 engaging the pins 12 of the plate 10. The pins 12 then move downwards in the inclined part 26 of the guide and pass the spring tongues 29 which prevent their return. During the first part of this movement flaps 19 hinged at 18 to the frame 5 are forced inwards against the resistance of the spring 22 until the projections 20 pass through slots 23 and retain the pile of tickets in position when the plate 10 is lowered. When the slide 24 is returned towards the right, the pins 12 work in the horizontal guideway 27 until the normal position is reached when they are free to move upwards in the guideway 28 under the action of the spring 11 on the plate 10. When the pile is nearly used up, the operating sector 2 for the ticket issuing apparatus is locked by a hook 17 which is operated as the result of a projection 14 on the end of the plate 10 engaging a lever 15 connected by a rod 16 to the hook. The hook may be disengaged by a key 18<1>.
