Abstract: 1,051,427. Glass sheet bending mould. LIBBEY-OWENS-FORD GLASS CO. July 29, 1964, No. 30095/64. Heading C1M. A mould for bending glass sheets comprises a continuous shaping rail 14 (Fig. 1, not shown) conforming in elevation and outline to a patterncut glass sheet to be bent provided on its upper edge with a shaping surface 16 of relatively smaller size than the glass sheet which it thus supports inwardly of the marginal edges and is characterized by a heat retaining member 17 extending inwardly from the shaping rail and being disposed closely adjacent to but spaced below the shaping surface to underlie a portion of a major surface of the supported glass sheet. In one example the heat retaining member 17 is a metallic screen 19, Fig. 2 (not shown), made of a foraminous material supported upon means 22, 23. To ensure that a very high tensile stress is not set up in the centre of the sheet the inner portions of the screen 19 are caused to be inclined away from the glass sheet. The tensile stress within the body of the sheet is balanced by the production of a narrow band of high compressive stress around the marginal edge of the sheet. If necessary more than one layer of material may be used to alter the amount of heat absorbed in certain areas below the sheet. Alternatively a heat retaining member 27, Fig. 5 (not shown), may underlie the entire area of the glass sheet within the confines of the shaping rail 14. The quantity of heat retained is controlled by resting a band 31 of the metallic material over a desired portion of the continuous web 29.

Title: Method of obtaining a harmonic from a series of periodically repeated impulses, and application of this method to telecommunication

Abstract: 726,519. Valve generating circuits. COMPAGNIE INDUSTRIELLE DES TELEPHONES. Nov. 3, 1953 [Nov. 10, 1952], No. 30324/53. Classes 40 (5) and 40 (6). [Also in Group XL (b)] The nth harmonic of a frequency f is produced by generating short rectangular pulses of repetition frequency equal to f and of such duration that the nth harmonic in the pulse spectrum is zero, applying the pulses to a bandpass filter having a centre frequency nf and feeding the output of the filter to a modulator circuit of the type described in Specification 449,999, so that the frequency nf is produced. Pulses having a repetition frequency f and a duration m/nf (where m is a whole number) are fed to a band-pass filter 10 which selects from the pulse spectrum one or more pairs of harmonics, the harmonics of each pair being corresponding ones on opposite sides of the'frequency nf. The output of the filter is applied to modulators 3 and 10, the output of modulator 3 being fed through a low-pass filter 7 to modulator 10 and the output of modulator 10 through a bandpass amplifier to modulator 3. By this means the desired harmonic nf may be obtained at 17.

Title: Timing and control means for use with hydraulic systems
IPC: C03B9/40
Filed: 1958-09-24
Abstract: Timing or other control means for use with oil hydraulic systems in which operations of machine parts are performed and/or controlled by oil-hydraulic rams or oscillating motors, particularly for performing operations automatically in a timed cycle, includes an oil-hydraulic master timing ram arranged to exert oil-hydraulic control on other mechanisms in the system and to and from which the flow of oil is regulated by valve and/or metering equipment to control the action of the ram and therethrough the timing of the mechanisms controlled by the ram.  In the form shown, oil is fed through an adjustable needle valve to the port 2 of the cylinder 1 housing the timing ram. The adjustable button 7 at the end of the ram rod 6 bears on a rod 8 slidable in a bracket 9. The rod 8 carries a bridge 12, to which return springs 13 are connected, and a yoke 11 for operating the shear mechanism of a glass press. The yoke 11 and bridge 12 carry dogs 32 to operate the lever 21 of a valve 22 which controls the oil supply to the ram which rotates the work-table of the glass press intermittently as described in Specification 943,893. A spring-urged detent lever 29 has <PICT:0943894/C1/1> recesses 28 co-operating with a roller 28 on the lever 21 to prevent the valve 22 being left in dead-centre position.  The supply of oil to the port 2 may be controlled by a valve actuated, in turn, by the movement of a rotatable worktable so that a repeating cycle of operations is obtained.  This may however, be arrested after each cycle by a spring-loaded latch 16 engaging a notch in the rod 8. A fresh cycle is then started by actuating the lever 19 to disengage the latch.

Title: A monochromatic optical maser

Filed: 1964-08-04
Abstract: 1,072,244. Lasers. NIPPON ELECTRIC CO. Ltd. Aug. 4, 1964 [July 19, 1963], No. 30565/64. Heading H1C. In order to provide substantially monochromatic light output in a laser at least one of the reflectors defining the resonant cavity of the laser comprises an optical system composed of a combination of a semi-transparent plane reflector and two plane reflectors. As shown in Fig. 2, a helium-neon or solid laser 20 is positioned between mirror 22 and optical system 25 forming a resonant cavity for wavelength selection. The optical system includes a semitransparent mirror 10 positioned at the Brewster angle to the light incident thereon from the laser tube 21 and arranged to reflect a first portion of the incident light on to metal reflector 11 positioned at an optical distance d 1  from mirror 10 and to transmit a second portion of the incident light on to metal reflector 12 positioned at an optical distance d 2  from mirror 10. If the wavelength selected for the output is X then in accordance with the invention the distances d 1  and d 2  are chosen so as to satisfy the relation (d 1  - d 2 )/# = K/2 + 1/4 where K is an integer. If this equation is satisfied then the intensity of light passing to light absorber 26 is zero and the optical system is equivalent to a plane reflector which does not impart a phase shift to the reflected light and which is disposed perpendicular to the incident light and spaced from the centre of mirror 10 by optical path lengths given by either where A R  and A T  are the phase shifts caused by reflection and transmission at mirror 10. The optical path distance d between reflector 22 and mirror 10 is also chosen so that the following equation is satisfied with the result that for any wavelength other than # the output power decreases sharply. Reflector 22 may be replaced by an optical system such as shown at 25.

Abstract: 174,223. Igranic Electric Co., Ltd., (Cutler-Hammer Manufacturing Co.). Nov. 2, 1920. Induction relays designed to respond to changes of voltage and phase relation in polyphase circuits are constructed with two field magnets 10, 11, Fig. 2, mounted side by side so as to generate two magnetic fields acting upon one armature 9, the latter consisting of a closed coil, approximately oblong in outline, pivoted to an horizontal spindle and adapted to move in narrow air gaps 22 which are formed as slots in corresponding poles of the two magnets. The armature is madeeither of thin strip material widened at the parts which lie in the air gaps, as shown in Fig. 4, and slotted to prevent transverse eddy currents, or it is formed of a number of turns of insulated wire, and may be shaped as shown in Fig. 6. The armature carries a glass tube 35, Fig. 7, containing two sealed-in wires 38, 39, and a body of mercury which separates into two parts 36, 37 when the tube is rocked. An adjustable weight 52<a> biases the armature so as to rock the tube into the position shown in Fig. 7, and thus breaks the circuit through the relay contacts when one phase fails or reverses, or when there is sufficient fall of voltage on both phases.
