Abstract: 386,552. Supply systems for consuming devices. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel, Eindhoven, Holland. June 25, 1932, No. 18013. Convention date, June 26, 1931. [Class 38 (iv).] Flashlight photographs are taken by causing a determined quantity of electric energystored in a container thereof to discharge abruptly through the filament of an incandescent lamp so as to overload the lamp and produce an intense illumination of short duration. The energy may be stored in a condenser or inductance, and the lamps used may have carbon or metal filaments. When condenser storage is used, an inductance (which may comprise one or both windings of a supply transformer) may be arranged in series with the lamps. Thermal inertia of the lamps may be reduced by preheating them. As shown in the Figure, the condenser 1 may be charged from an A.C. source through a transformer 9, 10 and rectifier 8 when a switch 5 is thrown over to 6, and be discharged through an inductance 2 and lamps 3, 4 when the switch 5 is thrown over to 7. In a modification, a switching arrangement is provided whereby (1) one of the windings of the transformer 9, 10 serves in place of the inductance 2, (2) the rectifier 8 is short circuited on discharge, (3) the transformer 9, 10 is switched off from the A.C. source on discharge, (4) the lamps 3, 4 are preheated either directly from the A.C. source or through an auxiliary transformer, as the condenser is charged. Reflectors may be used with the lamps. The Specification as open to inspection under Sect. 91 refers also to the use of a discharge tube as the lighting device. This subjectmatter does not appear in the Specification as accepted.

IPC: C14B1/44
Filed: 1926-07-21
Abstract: 256,218. Maschinenfabrik Turner Alkt.-Ges. Aug. 1, 1925, [Convention date]. Squeezing. - The pressure and counterpressure plates of a press for ironing and graining leather have sides which converge, e.g. are trapezoidal or triangular in plan, to avoid folding over of the creases near the edges of comparatively small skins and consequent damage to the leather. The invention is described as applied to a known type of machine in which hydraulic pressure is applied upwardly on a lower plate against an upper plate when a toggle arm carrying the upper plate reaches its working position. The plates are mounted on their supports with their centres of gravity on the line of pressure between the plates. Fig. 2 shows, in plan, one form of plate on a skin and Figs. 4 and 5 show respectively in section and side elevation a further form of plates 1, 2 which are curved towards the broader part and flat at the narrow part to smooth out the creases at the edges. Alternatively, the plates may be corrugated.

Title: Improvements in or relating to locking devices controlled by shock
Inventor: DRIVER DOUGLAS LOUIS ASHTON
IPC: G05G5/08
Filed: 1955-06-24
Abstract: 786,101. Locking devices. STANDARD TELEPHONES & CABLES, Ltd. June 24, 1955, No. 18272/55. Class 80 (3). [Also in Group XXXIX] A locking device for preventing movement of one member relative to another due to shock whilst normally allowing relative movement is particularly applicable to a telephone handpiece 15 supported in two spring-loaded clips 12 on a framework 4. The clips 12 are loaded by springs 11 acting through rods 9 which have enlarged collars 8 thereon. These collars 8 are adapted to move into bores 6 of locking members 1 to allow the clips 12 to move into the dotted positions for removal of the handpiece when desired. The locking members 1 are suspended by a number of springs 2 to the frame 4 as shown at the top of the Figure or by a coiled spring 22 tapered towards its middle as shown at the bottom of the Figure. In the event of a shock the members 1 are displaced transversely to the rods 9 to move the bores 6 out of alignment with the collars 8 and thus prevent the rods from moving against the springs 11. The two separate devices are arranged at 90 degrees to respond to shocks in any direction. A single device only may be provided when locking of a member by shock in one plane only is desired. Various different arrangements of two devices are also described.

Azeotropic evaporation, or centrifuging or thermal drying are then employed. The water may contain dissolved or dispersed finishing agent(s) such as acids, salts, alkalis, bleaching agents, whitening agents, dyes or pigments. The water is distributed in the organic solvent by mechanical agitation or pumping. Additional rinsing water may be added to the liquor during or subsequent to the treatment. The solvent may be recovered by decanting, distillation, condensation or absorption, and may comprise trichlorethylene, perchlorethylene, or trichlorotrifluoroethane. Examples of dyeing and brightening treatments are described.

Title: Improvements in workpiece shape control
IPC: B21B37/28
Filed: 1970-04-17
Abstract: 1291049 Rolling GENERAL ELECTRIC CO 17 April 1970 [14 May 1969] 18423/70 Heading B3M A method of controlling the shape of a plate comprises reducing a heated plate by passing it back and forth through a roughing mill 10 after which it is turned through 90 degrees and delivered to a finishing mill 24 when the plate is passed back and forth between rolls 28 and 30. The centre and edge gauge of a finished plate is determined by a thickness gauge 42 while a monitor 44 determines whether the plate is flat, has wavy edges or has a buckled centre area. Emoded readings from load cells 20 and 40, a pattern monitor 22, the thickness gauge 42 and the flatness monitor 44 are supplied to a computer 46. Other inputs to the computer are from a plate tracking system 48 and an auxiliary input 50 through which data is supplied as to the initial and final dimensions, the composition and the temperature of the plate at the beginning of the roughing phase. The computer 46 applies only two output signals, one to screwdown control 16 and the other to screwdown control 36. In determining the proper roll opening for establishing a particular crown during a particular pass, the roll separating force is determined from the equation where RM is proportional to the modulus of elasticity of the rolls, RD is proportional to the diameter of the rolls, MH is proportional to the hardness of the plate, PCW and RCW are proportional to the width of the plate, TC is proportional to the target crown on the plate, and ERC is proportional to the effective crown on the rolls. To determine the target crown in the final rolling pass the formula kW<SP>2</SP>, where k is a constant and W is the width of the plate in inches, may be used. The crown force equation can then be used to calculate the roll separating force required during the final pass. Having calculated the roll separating force for the last pass and along with the desired gauge following the pass, the entry gauge for the last pass can be determined from known plate deformation curves. The target crown for the next to last pass is determined and the roll separating force for the pass calculated using the crown force equation. The calculations are repeated for successively earlier passes until the calculated entry gauge of the plate for one of the passes is equal to or greater than the actual entry gauge of the plate at the beginning of the rolling schedule. During the roughing phase the term MH can be eliminated from the crown force equation since the slab is still relatively thick and hot.

Class 98(2) [Also in Group XXII] In making register pins for kinematograph films, the pins are swaged at intervals in bar stock, each pin having a head to fit a film perforation and a shank of smaller diameter than the head with a shoulder at the junction therebetween which is substantially perpendicular to the axis of the pin, the pins being interconnected by thin bridges at the bases of the heads, and subsequently severing the bridges at the periphery of the bases to complete formation of the pins and to separate them from each other.
