Title: Rectilinear combers
IPC: D01G19/26
Filed: 1965-09-30
Abstract: 1,120,191. Combing machines. N. SCHLUMBERGER & CIE. 30 Sept., 1965 [23 Oct., 1964], No. 41492/65. Heading DIN. In a rectilinear comber the detaching roller 2, of the reciprocating, web detaching device is driven with the reciprocating rotation motion required to intermittently feed back the web end for joining and yet ensure an overall advance of the web. The roller is driven by a chain 4 or other drive element which is subject to the simultaneous action of two independent drive systems at least one of which has a variable and reversible action. In Fig. 1, chain 4 runs over guide wheels 6, 7 carried by spring biassed chain tensioners 10, 11 on a beam 5 rotationally oscillated on a shaft 17 by a crank plate 19 and connecting rod 18. Chain 4 also engages a chain wheel 24 mounted on shaft 17 and constantly rotated from the shaft 27 of crank plate 19. Chain 4 is thus subjected to the constant drive of chain wheel 24 and to an oscillating drive due to the rocking motion of beam 5. When the two components are opposed the component due to the rocking beam overrides that due to wheel 24 and roller 2 is backwardly rotated to present a web end for joining. The positions of the pivots of connecting rod 18 and the size of pinion 26 driving chain wheel 24 are adjustable so that the motion of detaching wheel 2 can be adjusted for different conditions. Stationary wheels (30, 31) Fig. 3 not shown, may deflect chain (4) to provide an arrangement in which movements of beam (5) cause larger movements in the chain (4). In Fig. 4, not shown, a larger wheel is provided in place of chain wheel 24 and the chain 4 is arranged to engage it over a greater arc.

Title: Improvements in or relating to Optical Devices for Locating Graduation Lines
Inventor: LIEBERWIRTH CLAUS
IPC: G02B25/00
Filed: 1966-09-19
Abstract: 1,155,716. Measuring position photoelectrically. FEINMESS DRESDEN VEB. Sept. 19, 1966, No.41712/66. Heading G1A. [Also in Division G2] In a measuring microscope or other scale reading apparatus in which a graduation mark is located in a gap defined by a pair of parallel lines or other symmetrically disposed regions, the gap is made adjustable in width. As shown Fig. 1, an objective 1 forms an image of a graduation mark in the focal plane of an eye-piece 7. The adjacent faces of a pair of plates 2, 3, are located in substantially the same plane and each has a line marked thereon, the plate 2 being movable relative to plate 3 to adjust the gap between the lines and both plates being jointly movable to locate the image of the graduation mark. The eye-piece 7 may be replaced by a prism 8 which feeds the split beam 9, 10, to a pair of photo-diodes. In a modification a cam and cam follower arrangement ensures that during joint movement of the two plates by a measuring spindle, a slight displacement of one plate relatively to the other occurs to correct for systematic error in the measuring spindle. In a further form, Fig. 2, (not shown) the lines are located on faces of a pair of prisms which are movable relative to one another and have a partially reflecting interface so that the reflected image of one line is in the same plane as that of the other.

Title: Gas generator
IPC: F02K9/70
Filed: 1962-11-05
Abstract: 1,015,060. Rocket motors. ATLANTIC RESEARCH CORPORATION. Nov. 5, 1962 [Nov. 7, 1961], No. 41842/62. Heading F3A. [Also in Division F1] A combustion gas generator for use as a rocket motor burning an extrudible paste-like fuel which is fluid under stress at ambient temperatures comprises an extrusion member having at least one passage through which the fuel is extruded, means associated with the passage for dividing the fuel into a particulate spray, and a combustion chamber positioned downstream of the extrusion member in which the fuel spray is burned. As shown in Fig. 1, a piston 12 mounted in the forward end of a storage chamber 10 extrudes monopropellant 11 through an extrusion member 13 into a combustion chamber 14. The extrusion member 13, shown in detail in Figs. 2 and 4, has seven orifices 27 for positioning nozzle assemblies which have at their upstream ends retainer sections 28 each having a passageway in the form of a truncated cone 29 through which the propellant 11 is extruded. Swirl vanes 30 mounted in the cones 29 cause rotation of the propellant 11. Pressurized inert gas, such as nitrogen, is admitted into taps 21 and passes to a peripheral slot 22 in the extrusion member 13, from where it proceeds into passageways 23, 32 and 33 before being divided into two flows. The first or primary flow is directed into slots 36 tangential to vortex chambers 37 where it contacts the swirling propellant 11 leaving the cones 29 and prevents it from adhering to or clogging the sides of the chambers. The primary flow also imparts further rotational movement to the propellant 11 which begins to break up. The secondary flow is directed down passages 39 and out through openings 42 to atomize the propellant 11 emerging from the vortex chambers 37. The spray cone formed by the atomized propellant 11 can be varied by regulating the pressure of the gas admitted to the taps 21 and by varying the extrusion rate of the propellant 11. The secondary flow serves the additional function of blocking any burn-back of the flame in the combustion chamber 14 into the vortex chambers 37. Both primary and coolant flows also function as a coolant for the propellant 11 and extrusion member 13 to reduce the danger of auto-ignition of the upstream portion of the extruding propellant because of heat transfer and additionally protect the nozzle structure. The invention is not limited to using a monopropellant but can be used in a bipropellant system requiring only the substitution of an oxidizer such as oxygen or air for the inert gas.

Filed: 1975-10-15
Abstract: 1520649 Weighing MAATSCHAPPIJ VAN BERKEL'S PATENT NV 15 Oct 1975 [19 Oct 1974] 42154/75 Heading G1W Apparatus for determining the mass flow of goods comprises a conveyer carrying the goods from a feed station 12 to a receiving station 13, a dynamometer including oscillating strings S1, S2 which is connected to the conveyer or the receiving station to detect the reaction forces produced by acceleration of the goods by the conveyer or deceleration of the goods by the receiving station, and evaluating means 34 which detects the frequencies of the strings. As shown, conveyer 11 is movably mounted by links 12, and is connected by linkwork 23, 24, 25, 33 to two strings S1, S2 which are pretensioned by a spring 31. During successive time intervals T determined by generator 36, the oscillations of the two strings are counted by counters 35, 35' for a time # determined by a generator 37. The ratio of the two counts Z 1 , Z 2  which is proportional to the reaction force K, is determined at 38, and at 40 the ratio Z 1 /Z 2  is multiplied by T and divided by the conveyer velocity # to determine the mass added to the conveyer in the interval T. The total mass is then determined by the adder 45. In a modification, generator 37 is dispensed with, and the counts in each interval T are terminated when Z 2  reaches a predetermined value, K then being proportional to Z 1 .

Title: Improvements in and relating to apparatus for sensing information on a storage medium
IPC: G01R29/02
Filed: 1958-12-31
Abstract: 888,692. Electric digital-data-storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 31, 1958 [Dec. 31, 1957], No. 42256/58. Class 106 (1). Apparatus for sensing information on a storage medium includes sensing-means for producing electrical signals representing such information, means for converting such signals into unipolar signals and differentiating the latter, means for integrating the differentiated signals and trigger means for providing discrete information pulses from the integrated signals. Information stored in " non-return to zero " form on a storage medium such as a magnetic tape is sensed by a transducer to produce an output waveform A which is fed over a line 10 to a phase inverter 11. The phase inverter produces an output on a line 12 comprising a waveform corresponding to the input waveform A, together with one 180 degrees out of phase with it. These waveforms are fed to a mixing and clipping stage 13 to produce an output waveform B. The waveform B is fed to a differentiator 25, a diode 28 being provided to eliminate negative swing in the output waveform E. The waveform E passes over a line 29 to an amplifier and clamp 30 arranged to shift the reference level of the amplified output below earth potential, as shown in waveform F. The waveform F passes to an integrator 15, a diode 33 blocking positive voltages. The output G of the integrator passes to a Schmidt trigger circuit 21 turned on when the grid potential of the left-hand tube rises above a threshold level and turned off when this potential falls below the threshold level. Each trailing edge of the waveform H corresponds to a binary " 1 " read from the storage medium and the information finally passes to a register 24 where it is effectively in the form illustrated by the waveform J. The function of the differentiator 29 is to obviate the time displacement in the pulses supplied to the register 24 which would otherwise occur. A circuit for the amplifier 30 is described in detail. Specification 875,694 is referred to.

Abstract: 430,503. Colour photography. OPTICOLOR AKT.-GES., Glarus, Switzerland. Dec. 21, 1933, No. 35981. Convention date, Dec. 29, 1932. [Class 98 (ii)] To reduce the colour degradation produced by diffusion between the zones of the striped filter used in taking and projecting lenticular films, the films are copied by projection using a diaphragm having apertures arranged with their centres so spaced apart that the effective centres of the lateral partial images on the copy (defined as the point or line for which the vector sum of all distances multiplied by the corresponding intensity of blackening is equal to zero) have a greater distance apart than the effective centres of the corresponding images on the original. The spacing of the apertures is chosen so that the diffusions between the images are the same, the centres of the lateral apertures being farther apart than two-thirds of the diameter of the aperture of the objective. A diaphragm of the form shown in the Figure, having apertures 9, 10, 11 may be used. The form of diaphragm is determined experimentally by exposing a film behind a filter having two zones obscured, copying this with an approximately correct diaphragm, and projecting the copy through a filter with two zones obscured. The form of diaphragm is then varied until the intensities of light passing each zone is the same. The process is applicable to filters having more than three zones.
