Filed: 1918-03-06
Abstract: 130,663. Mauclaire, L., Garbarini, A., and Gautier, G. Oct. 13, 1917, [Convention date]. Arc lamps.-In order to maintain the crater in its required position relative to a lens, reflector, diffuser, shade, &c., a part of the radiation passing through a circular or narrow rectangular aperture in a diaphragm D, Fig. 1, is utilized to heat an expansible or deformable regulator Y of shape corresponding to the aperture, carrying contacts in the circuits of a relay or motor effecting the necessary adjustments. When an oblique or annular negative electrode is used, the diaphragm may be in a plane at right-angles to the axis of the positive electrode. A regulator for use with a circular aperture, which may be fitted with a lens, is shown in Fig. 3. Displacement of the crater causes one or other half of an inner ring E to expand into contact with a screw A or R carried by the insulated halves of an outer ring F preferably of the same material as the inner ring. Both rings may be of channel section. Another regulator is a bimetallic strip forming a nearly complete circle and secured at its middle point. Fig. 6 shows semicircular tubes S, U filled with air or the like and closed by mercury or solid pistons Z forming contacts. When an oblong aperture is provided, the regulator may consist of a solid fork, the limbs of which expand lengthways into contact with screws on a frame when the beam is displaced from its normal position between them. Other forms comprise a bimetallic fork, Fig. 9, a pair of parallel air-tubes with pistons, or a metal strip united on opposite sides with strips of another metal, the radiation normally falling on the middle strip According to the Specification as open to inspection under Sect. 91 (3) (a), one half of the regulator shown in Fig. 3 may be omitted when the negative electrode is oblique or annular. This subject-matter does not appear in the Specification as accepted.

Title: Connecting device for wave guides of any direction
IPC: H01P1/02
Filed: 1949-02-15
Abstract: 657,450. Wave-guides. COMPAGNIE INDUSTRIELLE DES TELEPHONES. Feb. 15, 1949, No. 4096. Convention date, April 8, 1948. [Class 40 (viii)] A connection device between two circular wave-guides G1, G2 at an angle # to each other is designed to propagate an Hon wave without loss. To this end it comprises three curved portions C1, C2, C3 of circular guide arranged in succession and situated respectively in three planes Q1, Q2, Q3 such that plane Q2 is perpendicular to plane Q1, and plane Q3 is perpendicular to plane Q2. The angles #1, #3, through which the two outer portions C1, C3 are bent are each equal to an odd number of half multiples of Án#/#2R radius, where Án is the nth non-zero root of the Bessel function J1, A is the free-space wavelength, and R is the radius of the wave-guide. Then, since the two straight portions of the guide are at an angle #, the angle #2 of the middle bend is given by the formula With this arrangement an Hon wave entering guide G1 is transformed by curve C1 into an E/n wave so polarized with respect to the plane of curve C2 as to pass without change or loss. Then curve C3 transforms the E/n wave back to Hon where it issues from G2 without loss. Sections of straight guide may be interposed between the curves without affecting the operation. Also, if it is desired to have the input and output guides in the same plane, there may be interposed an S-shaped guide having parallel input and output. Specification 643,601 is referred to.

Title: Improvements in or relating to Burglar Alarm Systems.
Inventor: CARPENTER CHARLES AUGUSTUS
IPC: G08B13/12
Filed: 1916-03-22
Abstract: 104,918. Carpenter, C. A. March 22, 1916. Burglar and like alarms. - In systems of the kind in which a networl: of conductors, embedded in or otherwise applied to the structures to be protected, is adapted when cut or fused to cause the sounding of an alarm, a continuous wire is embedded in, or secured to, the interior surface of each section of protective covering, leaving two terminals, so that adjacent sections can be readily connected up in series and the connexions concealed. The sections may comprise any suitable material or combination of materials, such as strips, webs, frames, or panels of wood, paper, matting, glass, or metal, and may be applied to structures such as walls, floors, ceilings, and doors, or to articles such as safes, book-cases, or backs of pictures. The conductor may be concealed in metal frames supporting the glass panes in the case of windows &c. The system operates either on breaking contact at the terminals, as by opening a door or window, or by breaking of the conducting-wire. The network A is in series with a battery F and a normally energized relay G. Breaking the network circuit releases the relay armature I, which closes the circuit of an alarm bell K. The apparatus is set for operation by a switch in the form of a lock L. The bolt l, in its outward movement, first momentarily closes contacts m by a projection l<1> depressing an arm l<2>, thus energizing the relay, which closes its own hold-on circuit. The bolt then bridges contacts h, h' and forms part of the bell circuit. The bell is connected up by wires concealed at the back of the baseboard. The usual bell terminals are replaced by dummies connected together at the back of the baseboard; and connected up in the network circuit as shown, so that disconnecting the visible wires with a view to putting the bell out of action breaks the network circuit and causes the bell to ring. According to the Provisional Specification, a strip or length of material may, during manufacture, be provided with wires running lengthways, the material being afterwards cut to the size required and the exposed ends of the wires connected to form a continuous conductor.

IPC: D01D1/06
Filed: 1951-02-22
Abstract: <PICT:0706492/IV (a)/1> <PICT:0706492/IV (a)/2> Apparatus for the storage and discharge of viscose includes a battery of storage tanks, a common sump or drop tank in the form of a large-bore main placed below and close to all the storage tanks, a discharge opening in the main for the passage of viscose and an additional opening therein situated as far as possible from the discharge opening and a pipe control valve connecting the lowest point of each storage tank with a point in the main between the discharge opening and the additional opening, the main having a capacity large enough to maintain a discharge of viscose at full pressure for at least 15 minutes after one storage tank has been discharged and before another is discharged into the main.  As shown in front elevation in Fig. 1 and side elevation in Fig. 3, a battery of storage tanks 1 are each connected by short connecting pipes 2 to a common main 3, from which viscose is discharged through trunks 7, 71 and passed to spinning machines or other apparatus by two pumps 4, 41.  The connecting pipes 2, Fig. 3, enter the main 3 at a tangent to the lowest point of its circular cross-section and the control valves 5 are placed below the level of the highest point of the main.  The main 3 and each storage tank 1 have vents 6 and 10 respectively open to the atmosphere.  In an alternative arrangement the trunk 71 and pump 41 are replaced by a feed-back pipe having a regulating valve and connected to the trunk 7.  As viscose is discharged through the pump 4 into the trunk 7, a proportion of the flow is fed along the feed-back pipe to the end of the main remote from the discharge pump, thus producing a circulating flow of viscose through the main 3 to prevent the formation of stagnant zones.  In a third arrangement the storage tanks 1 are arranged in a circle, the main 3 is in the form of a closed ring and the trunks 7, 71 or the trunk 7 and the junction of the feed pipe with the main are situated diametrically opposite to each other. Specifications 356,182 and 553,490 are referred to.
