[Class 20 (iv).] Flat structural elements are held in spaced parallel relationship 'to a supporting element by means of spring clips, each clip being connected at one end to the supporting element and at the other end being provided with means for engaging and directly supporting a flat element. In the construction shown in Figs. 1 and 2, partitions 26 are held in position upon channel members 22 by means of channel strips 31, to which they are attached by resilient clips, each consisting of a loop 37, a channel-shaped flange 38 engaging the strip 31, and a number of fingers 39 forming two oppositely-disposed channels to receive the edges of two adjacent panels. The panels preferably consist of gypsum or other cementitious material faced with paper sheets and are covered on the outside with plaster 36. Ceiling panels 53 are suspended from channel strips 47 by resilient clips 49. Where the ceiling meets the panels 26 the clips are formed with fingers 57 adapted to engage the ceiling panels and the wall panels. The flooring is supported on sleepers 62 which rest on resilient clips 64 secured by cement to the masonry floor 20. The base of the clip is cut away as shown at 73 to enable nails to be driven through the top part of the clip into the end of the sleeper. At the junction of the floor and the wall a trim plate 76 is provided which is secured to a wooden strip 78 to form compartments for electric wires. The strip is preferably secured to the panel 26 by resilient staples 79, as shown in Fig. 8, each staple having reversed bent flanges 80 and bent prongs 82. When the wall panels are to be attached to a brick or tile wall a connection, shown in Figs. 6 and 7, may be employed. One end of a clip 96 is secured by nails 98 driven into a mortar joint, and the other end is provided with flanges 102 for engaging the flanges of a channel strip 104. Clips 105 connect the strip to the panels 26. Alternatively a connection of the form shown in Fig. 13 may be used comprising a pair of clips 132 or 138 secured to the brick or similar surface by nails 134 and to a channel strip 137 by flanges 135.

Abstract: 440,975. Automatic exchange systems. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, Westminster, and DIXON, R. G., 162, Westmount Road, Eltham Park, London. Aug. 29, 1934, No. 24884. Drawings to Specification. [Class 40 (iv)] Finder switches of non-homing type associated with allotters are given a routine test by apparatus which creates an artificial demand in the allotter, this demand however being rendered ineffective when an ordinary demand occurs. The invention is described with reference to a system employing normal and overflow primary finders, the latter associated with secondary finders, the system being largely identical with that described in Specification 422,644 but differing in the following respects : (1) a test of the continuity of the speaking wires of each finder tested is effected by a bridged relay plugged across the test line, operation of this relay being necessary before the allotter and finder can be released to initiate a further test ; (2) preference is given to one of the two sub-groups of a group of calling lines when calls simultaneously arise in both sub-groups and, if an artificial demand is applied to the starting circuit of the preferred sub-group when a call arises in the other, a lamp is lit to inform the attendant who must then temporarily release the routine-test key ; (3) it may be arranged that a finder operating as the result of an artificial demand can only stop on the special test line after testing all the ordinary outlets and this may be effected by causing a finder on release after engagement with the test line, to maintain a busy marking on the line for a time sufficient for a further finder to be allotted and to pass completely over its ordinary outlets ; (4) the selector associated with a secondary finder may maintain a busy marking on the corresponding allotter contact for a time longer than that required to allot a further finder to ensure that a different finder will be allotted during the next test; (5) small modifications occur in the circuits for dealing with irregular operation in the primary and secondary allotters. Specification 405,436, [Group XXXVII], also is referred to.

Title: Improvements in electric relay arrangements
IPC: H01H47/00
Filed: 1927-09-27
Abstract: 302,422. Relay Automatic Telephone Co., Ltd., Davis, F. W., and Wilding, F. A. Sept. 27, 1927. Semi-automatic exchange systems.- A relay I with a copper slug or a short-circuited winding is insensitive to one or more impulses from a relay L which chatters in response to alternating or pulsating current, but is made to respond to a greater number, by causing the relay L to shortcircuit the operating winding e between impulses. The resistance g in the energizing circuit may be irductive. Relay L may be the ringing-responsive line relay at the manual end of a two-way automatic-manual junction and the arrangement prevents any effect from the operation of relay L due to the reversal of the line current when a manual-automatic connection is taken down.

Abstract: 1340930 Photographic camera shutter control NIPPON KOGAKU KK 19 April 1971 [6 April 1970] 25679/71 Heading G2A Light incident upon a photo-sensitive element P from an object to be photographed induces a voltage whose magnitude is in proportion to a logarithm of the current flowing through the element, the voltage being compared with a second voltage induced by a correction current i for setting a film speed and a current whose magnitude is varied in response to a number of pulses counted by a binary counter CU so that when the difference between the first and second mentioned voltages reaches a predetermined value the counter is stopped and during a subsequent shutter operation a current in proportion to an expotential of a voltage representative of the count stored in the counter is used to charge a capacitor C, the shutter being closed when the integrated value reaches a predetermined level. Pulses from a pulse generator PG1 are fed to the counter CU via a gate GT, the counter being periodically reset by a further pulse generator PG2. The voltage difference is detected across a diode D and when it reaches a predetermined value the potential at the output of operational amplifier B goes negative to inhibit gate GT. Upon depression of the shutter button, switch S 4  is opened and switch S 3  is closed to inhibit gate GT after a time delay sufficient to allow CU to complete counting. Upon completion of counting switch S 1  is moved to contact u, switch S 2  is opened, and when the shutter opens switch S 5  is opened. The photo-  voltaic element P may be replaced by a photoconductive element. An indicator IND connected to the counter via a decoder DEC indicates the state of the counter and may be a photo-emitting diode or a multi-tip or monothilic type of indicator.

Title: Improvements in and relating to hydraulic jacks
IPC: B66F1/00
Filed: 1935-09-18
Abstract: 445,241. Lifting - jacks. SOMMERSTAD, T. O., 19, Holtkampstrasse, Sterkrade, Oberhausen, Germany. Sept. 18, 1935, No. 25881. [Class 78 (iii)] A hydraulic lifting-jack, in which the cylinder 1 and piston 3 are supported alternately upon built-up battens or like ground supports, so that an accumulated lift can be obtained by repeated operations of the jack, is characterized by the enlargement of the base of the cylinder all round its periphery so as to provide room for an enlarged base of the piston ; the two bases forming one flat surface 2, 4 when the jack is in the collapsed out-ofuse position. The enlargement 4 of the base of the piston allows return springs 5 for the latter to be fitted outside the cylinder. In operation, the cylinder is raised first and supported on battens while the piston rests on the ground. The springs are then allowed to collapse and raise the piston and a thinner batten is placed under it. A second operation of the jack then results in an initial lowering of the piston on to the thinner batten and then a raising of the cylinder from the thicker battens. The latter are then turned over on to their sides which correspond in thickness to the thinner batten. The cylinder is then re-lowered on to these thinner battens. The three battens then form a new level surface from which a second cycle of operations can be commenced.
