Class 20(iv) A roofing supported by pillars, columns or walls f consists of one or more rows of self-carrying elements a, b each formed by an arched surface or of two flat or curved surfaces capable of withstanding tangential but not perpendicular forces and meeting along a common generatrix g, the elements having ties e or struts e<SP>1</SP> connecting their opposite outer edges and their sequence being such that the juxtaposed margins of adjoining elements in a row, either of which margins may be rectilinear or curvilinear, are on different levels to form a free space k for lighting and ventilation. In one form, Fig. 7, comprising elements with cylindrical surfaces in each of two rows, the generating lines of elements a are perpendicular to those of elements b, and the free spaces k face in four directions in pairs. In a construction providing free spaces with upper and lower curvilinear margins, the ties may be concealed along the lower margin and suspended by bars from the upper margin. In another, Fig. 14, elements b comprise concave surfaces meeting along a generatrix at the height of the uprights f, or both elements may have this inverted formation, being placed at different ends to provide the spaces k, other embodiments comprise elements composed of two surfaces having a double curvature. In a modification shown in Fig. 21, instead of the two surfaces of an element meeting along a common generatrix, the plane surfaces of all but a central element are separate and lie on opposite sides of this element, being connected only by ties e and struts e<SP>1</SP>, all the surfaces being supported on two rows only of uprights f. Other constructions comprise uniformly arranged elements of plane surfaces an outer margin of which is at a different level from the other to provide a glazing space.

Title: A method for remotely controlling an automatic telephone answering device and a telephone answering device for use by said method
IPC: H04M1/652
Filed: 1970-05-15
Abstract: 1,261,468. Telephone answering machines. PIONEER ELECTRONIC CORP. 15 May, 1970 [19 May, 1969], No. 23747/70. Heading H4K. A telephone answering machine is interrogated by means of a remote control signal which is recorded on a message track of a recording tape and on a second track of the same tape after passing through a filter so that during playback of any recorded messages the reproduction of the signal from the second track causes the machine to return to a standby condition. In operation after a ringing signal has been detected by starting circuit 2 for a given time the switching circuit 3 operates to bring up relay Y1 which connects the incoming line 1 to transformer 4. Relay Y1 remains operated by the action of timer circuit S. A recorded announcement is replayed to the caller from tape T1 in the normal way. When the announcement is finished stop foil 8 causes relay Y2 to operate and start recording tape T2 and cause a tone to be sent to the caller from oscillator 12. The caller can then record a message on tape track t21 by energizing recording head 14 through amplifier 13. At the end of the message, or when the time set in circuit S expires relay Y1 opens to return the machine to a standby condition. If instead of recording a message a predetermined remote control signal is sent, this signal is recorded on track t21 of the tape and passes through filter circuit 15 to be recorded on track t22 of tape T2 by head 16. It also passes through pulse generating circuit 17 to operate after a predetermined time bi-stable 18 causing relay Y3 to operate and rewind the message tape. Operation of relay Y3 also closes contact Y35 to override timer S and hold relay Y1 operated. A conductive foil at the start of tape T2 causes the tape drive to be reversed and the recorded messages replayed to the caller through amplifier 13. At the end of the recorded messages the remote control signal on track t21 of tape T2 is replayed to indicate to the caller the end of the recorded messages. The remote control signal on track t22 simultaneously energizes circuit 17 which after a delay causes bi-stable 18 to reset and opens relay Y3 causing relay Y1 to drop and thus return the machine to a standby condition.

Patent GB-757022-A (GB)
Title: Improvements in or relating to electric circuits comprising gas-filled glow discharge tubes
IPC: H01J17/30
Filed: 1952-09-26
Abstract: 757,022. Cold-cathode tubes. TELEFONAKTIEBOLAGET L. M. ERICSSON. Sept. 26, 1952 [Sept. 29, 1951], No. 24226/52. Class 39 (1). The ignition delay of a cold-cathode glow discharge tube is reduced by means of a preionizing electrode formed by an electrically conducting body with which a material, preferably glass, is associated in such a way as to be contiguous with said body and interposed between the latter and a further electrode with which the pre-ionizing electrode co-operates to form a priming gap. The tube is connected in a circuit in which the potential applied to the preionizing electrode is such that the current flowing through the material and across the priming gap is sufficient to decrease the ignition delay of the tube, but is not sufficient to lower appreciably the breakdown voltage of the main discharge gap of the tube. Fig. 2 shows a tube comprising an anode 1 and cathode 2 connected through a switch 11 to a voltage source 4. A pre-ionizing electrode 3 comprising a leadin wire 12 and a coating 9 of glass or other semiconductive material forms a priming gap with the cathode 2 and is supplied by a separate source 10. The coating 9 acts as a limiting resistance in the priming circuit. Alternatively the electrode 3 may form a priming gap with a further auxiliary electrode or with the anode. In a modified arrangement the electrode 3 is connected directly inside the tube to either the anode or the cathode, in which case the voltage source 4 also maintains the priming discharge. A trigger electrode may then be connected through a switch to the source 10. In the arrangement shown in Fig. 4 the preionizing electrode 3 comprises a band 12 of metal or carbon on the outer surface of the tube envelope, a portion 9 of the glass envelope itself forming the limiting resistance. The Specification describes a circuit including an electronic time meter used for investigating the effect of the pre-ionizing electrode on the ignition delay as compared with the effect of placing a small quantity of radio-active cobalt in a tube similar to that shown in Fig. 4 and having a filling of neon and 1 per cent argon at a pressure of 70 mm. of mercury.

Title: Improvements in and relating to lacing apparatus and the product produced thereby
IPC: F16G3/00
Filed: 1928-08-23
Abstract: 321,743. James, R. W., (Larson & Co., Inc., C. B.). Aug. 23, 1928. Belt fastenings.- A number of belt-fastening hooks, each with a loop 17 and arms 21, 22 of different lengths and in different planes are clinched into the end of a fabric or other belt 35, which may have a fabric wrapping 36 to prevent unravelling, by a hand-operated machine in which the clamps 3, 4 securing the belt end are moved laterally step-by-step, one hook being clinched in position at each step. The hooks are packed, with a rod engaging in their loops, sideby-side in containers 65, Fig. 10, which are fitted in a magazine 68 carrying plates 69 with elongations 70 for assisting to hold the hooks in position when they are fed to and moved by a slide 14 into engagement with the belt end. A spring-pressed pin 78 on the magazine engages one of a series of holes on the framing so that different containers may be moved into register with the slide 14. An arm 80 spring-supported on a member 79 operated by a screw-thread on the main operating-shaft 6 bears on the end of a pack of hooks in a container, so that they are pressed singly into recesses in the end of a stem 16 on the slide 14, which is operated by a cam 7 on the shaft 6. A spring 23 and blocks 19 assist to grip the hooks, the blocks moving with the stem 16 until they contact with anvils 42, 25, when the stem carries the hooks forward into slots in the anvils in which move hammers 33, 34. The anvils are pressed towards the belt by springs, when released by the advance of the hammers, which are actuated by stems 31, 32, adjustable to vary the depth of clinching on either side of the belt. The stems 31, 32 are operated by levers 27, 28 cam-operated by the shaft 6, the pivots 29, 30 of the levers being carried on rods 51, 52, which are screwed to engage an adjustable nut rotated from an eccentric 8 on the shaft 6 to move the pivots 29, 30 and assist the clinching effected by the rocking of the levers. The lateral step-by-step movement of the clamps 3, 4 between each clinching-operation is effected by a pawl 37 engaging a ratchet edge 38 on the clamp 3 and operated by rotation of a shaft 39 by action of the eccentric 8 upon a member 39<1>. When the clamps 3, 4 have completed their travel and are to be reset, the shaft 39 is rotated by a lever 87 so as to withdraw the pawl 37 from the rack 38, a latch 88 then engaging the framing to maintain such withdrawal. The lever 87 then lies in the path of a pin 89 on the cam 7, so that the shaft 6 cannot be rotated until the pawl is restored to operative position.

Title: Measuring electrical potentials
Inventor: RIPPON KENNETH PHILIP
IPC: G01J3/32
Filed: 1953-09-03
Abstract: 781,167. Photo-electric measurement. HILGER & WATTS, Ltd. Sept. 3, 1954 [Sept. 3, 1953], No. 24397/53. Class 40 (3). [Also in Group XXXVI] Apparatus for measuring a voltage comprises a double triode comparator circuit producing an output voltage, dependent in magnitude on the difference between the unknown voltage and a voltage increasing or decreasing from a fiducial valve at a known rate, which holds open a diode bridge switching circuit, energized from an A.C. supply circuit to excite an amplifier, phasesensitive rectifier and counter, until the output voltage is zero at equality between the unknown and comparison voltages, so that the switching circuit is closed and the counter stops at a value representing the unknown voltage. For measuring a photomultiplier voltage V integrated across a condenser C in the spectrochemical analysis apparatus described in Specification 727,410, there is provided a double triode V1 whose anodes are connected to a positive H.T. supply, grids are respectively connected to the voltage V and to a comparison voltage VR decreasing at a known time rate from a known initial value, and cathodes K1, K2 are connected to the negative H.T. supply over equal load resistances. The voltage between the cathodes is connected across the first diagonal of a comparison bridge comprising four diodes V3 to V6, whose second diagonal is excited with an alternating voltage at frequency f from transformer T1. Voltage VR initially greater than V is derived from the anode of a pentode V2 connected in an integrating circuit of the kind described in Specification 580,527, [Group XL], in which on arrival of a starting pulse at the suppressor grid the voltage VR linearly diminishes with elapsed time. When VR > V, the diode bridge is unbalanced to develop a voltage at frequency f across the second diagonal, which is transformer coupled to an amplifier, a phase-sensitive rectifier and a counter, which is started at the instant at which the fall in VR commences, and arrested at the instant at which V = VR and the difference therebetween is about to change sign. Then the voltage difference between the cathodes K1 and K2 is zero, the diode bridge is balanced, and the alternating voltage supplied to the counter chain is zero. It is stated that the rate of change of VR may be controlled by a further voltage in terms of which V is measurable.
