Title: Improvements in barrel assembling machines
IPC: B27H5/10
Filed: 1921-03-16
Abstract: 178,676. Podsiad, F. March 16, 1921. Machines for assembling and hooping. A machine for assembling barrels comprises a frame, a drum rotatably mounted on each side of the frame, a conveyer or endless feed-chain having stave-engaging projections extending from it at intervals mounted adjacent to each drum, means on one of the drums for releasably engaging the staves, means for fixing the end hoop, and further means for disengaging the assembled shell from the drums. In operation, metal or wooden end hoops 300 are mounted on the inner'edges of the drums 70, 90, and staves 200 are fed on to endless chains or belts 52 mounted on shafts operated by gearing from a drive-shaft 20 operated by a footlever 22, the left-hand drum 90 being caused to turn by a belt drive from the same shaft. The staves 80 are fed towards the lowermost parts of the two drums. The left-hand drum 90 contains radial slots 91 in which are arranged pivoted dogs or hooks 92 normally held upright by springs 94; just before a hook meets one of the oncoming staves it is pressed to the left by the end 111 of a rod 110, so making room for the stave between the hook and the engaging flange of the opposite-drum 70. The hook then returns to hold the stave securely, the following staves being held by the drums in a similar manner. When the barrel shell is completely assembled, a lever 80 is operated to urge forward the flange 76 of the drum 70 carrying the hoop 300, which hoop is by this means forced over the end of the shell. The hoop at the other end is applied by similar mechanism not illustrated. To release the hooped barrel from the machine a lever 109 is moved to the left, thereby causing the drum 90 also to move to the Left; the completed barrel can then be removed from the drums. A clutch 31, 32, operated by a foot-lever 38, is provided to enable the drums to be rotated to adjust or remove a defective stave without movement of the conveyers.

Title: Apparatus for adjusting equalizers of signal transmission systems
IPC: H04B3/10
Filed: 1973-02-21
Abstract: 1384502 Automatic equalizers WESTERN ELECTRIC CO Inc 21 Feb 1973 [22 Feb 1972] 8435/73 Heading H4R Apparatus for adjusting an equalizer including a plurality of separately adjustable transmission sections each having a different frequency response characteristic, comprises means to determine the normalized frequency response of each equalizer section in each of a plurality of ranges, i.e. the response independently of the effect of a control voltage, means to determine the misalignment of the complete equalizer in each of said ranges and means responsive to both the determining means to produce control signals for each section. In one embodiment shown, an equalizer 10 comprises a series of transmission sections 10-1 to 10-n each having a bump characteristic in a different frequency band but having a secondary effect in other frequency bands. The invention is similar to that of Specification 1,326,799 and 1,326,800, but provides a more exact compensation taking account of the secondary effects. As shown, a sweep frequency test signal is applied to the line 8 at 14 and the output of the equalizer 10 is compared at 16 with a reference signal V R  to produce error signals # 1  to # n  characteristic of the misalignment in the different frequency bands. The equalizer is also topped at Vo to V n  to detectors 22- n  to 22- n . Comparators 24-1 to 24- n  compare the detector outputs and thus derive the individual frequency characteristics of the equalizers which are normalized at 26-1 to 26- n  and integrated at 28-1 to 28- n  over each frequency band. Thus the integrators each produce a train of co-efficients representing the effects of the associated equalizer section on each pass band. A processor 20 receiving these sets of co-efficients and the error signals # 1  to # n  solves sets of simultaneous linear equations to produce adjustment codes P 1  to P n . Current sources 30-1 to 30- n  produce currents in accordance with received codes and control the temperature of thermistors in the equalizers.

Title: Solid state oscillator
IPC: H03B15/00
Filed: 1966-02-25
Abstract: 1,095,627. Semi-conductor devices. HITACHI Ltd. Feb. 25, 1966 [March 5, 1965], No. 8512/66. Heading H1K. High frequency oscillations are generated in a semi-conductor body through which a current is passed perpendicularly to a magnetic field the magnitude of which controls the frequency. The frequency is further controlled by subjecting the body to mechanical stress. Figs. 1 and 2 (not shown) illustrate a semi-conductor body (5) mounted in a cavity attached to a waveguide, this assembly being placed in a container filled with liquid nitrogen or liquid helium. The container is placed between the poles of a magnet. The frequency of the oscillator is varied by altering the thrust applied to the semi-conductor body by an insulating rod (6). Fig. 3 (not shown) represents a similar embodiment in which the semi-conductor body is housed in a piston-tuned cavity adjacent to which are superconductive coils-at (26)-to apply the magnetic field. The assembly is housed in a container filled with liquid nitrogen the inlet (22) being tightly stopped with glass wool. The embodiment of Fig. 4 is a low frequency device (e.g. of the order of 100 kc/s.) in which the oscillator element is mounted on a silica substrate 40. The output frequency is too low for distribution by waveguide so to obtain the output in load 49 one face 47 of the oscillator is made optically flat and is contacted by a similarly flat face of a semiconductor body 46 containing a PN junction to provide an output from the plasma density waves from the oscillator body. The semiconductor used is a material the significant impurity of which has been at least partially compensated, preferably to an extent of greater than 50%. Suitable semi-conductors are indium antimonide (doped with tellurium), lead telluride, silicon and germanium. The oscillator may be used in conjunction with a detector (also operated at low temperature) as a superheterodyne oscillator or it may be used alone as a detector to provide an oscillatory output only when an input signal is applied.

Title: Photographic silver halide material containing development inhibitor releasing couplers
IPC: G03C7/26
Filed: 1976-03-04
Abstract: The photosensitive colour-photographic multilayer material contains, assigned to at least one silver-halide emulsion layer, two non-diffusing DIR compounds which, as a consequence of a coupling reaction with oxidised colour developer, liberate a diffusing mercapto compound which inhibits the development of the silver halide, or one DIR compound in two different dispersion forms. Either the two DIR compounds or the two dispersion forms differ in reactivity (keff) by a factor of more than 1.5. This enables the gradation form of the silver-halide layer to be adjusted in a targeted manner using only two DIR compounds of different reactivity or even using only a single such compound.

Title: Hydraulic drive transmission
IPC: B60K17/10
Filed: 1955-03-25
Abstract: 790,125. Fluid-pressure servomotors. AUSTIN MOTOR CO., Ltd., and HORWOOD, N. March 16, 1956 [March 25, 1955], No..8689/55. Class 135. In an hydraulic drive transmission, e.g. for a motor vehicle comprising an engine-driven variable capacity pump which drives one or more variable capacity motors the capacity adjustment mechanism of the engine-driven pump 13, Fig. 2, is actuated by a pressure-responsive servocylinder 14 in such a way that increased servo-cylinder pressure reduces pump capacity. Fluid under pressure is admitted to the servo-cylinder 14 as a tapping from the pump delivery line 18 and is metered by a valve 27 which is controlled by a governor 32 directly responsive to engine speed and is within a housing 15. The valve member is so shaped, e.g. as a double needle valve, that, during its travel from one limit of its stroke to the other, the valve aperture area decreases to a minimum and then increases so that, at different positions of the valve member in its travel, the same valve aperture area occurs and the pump capacity adjustment mechanism is affected accordingly. The position of the valve member 27 as determined by the governor 32 determines the pressure in a chamber 26 which is connected by a pipe 25 to the servo-cylinder 14 the piston of which is connected to a damper 24 and controls the angle of inclination of the swash plate 22 of the variable-capacity pump 13. The delivery pipe 18 is connected via a changeover valve 20 to one or more servo-cylinders 17, e.g. one for each of the two steerable front wheels, the piston of which is connected to a dashpot 40 and controls the position of the swash plate 38 of a variable capacity motor 16. The change-over valve 20 enables a reverse drive of the road wheels to be obtained: The valve housing 15 contains a spring-loaded piston valve 36 which is operated by excess pump delivery pressure, caused for example by violent acceleration, to close the outlet from the chamber 26 whereupon the pressure in this chamber builds up and the servo-piston 14 is moved to reduce the pump capacity. A second spring- loaded piston valve 37 in the housing 15 is in the connection between the delivery line 18 and the valve chamber 26. The piston is subjected to the pressure in the low-pressure chamber 34 so that if there is a build-up of pressure in the low-pressure pipe line, for example due to the motors acting as pumps when the vehicle is over-running, the supply to the chamber 26 is closed and the servo-piston 14 is moved to reduce the pump capacity and so increase the braking effect of the pump.
