Title: Apparatus for Changing Bobbins on a Spinning Machine
Inventor: WASNER HERBERT
IPC: D01H9/00
Filed: 1967-03-31
Abstract: 1,179,632. Unwinding machines. VEREINIGTE VIGOGNE-UND GROBGARNSPINNEREIEN VEB. 31 March, 1967, No. 14889/ 67. Heading D1J. Apparatus for changing unwound supply bobbins for full ones on a spinning machine without stopping the machine comprises a pivotal member 18 having fingers 19 in which ends of yarn 21 from a reserve bobbin, or bobbins 35 are engaged whilst ends of yarn 29 are fed by grafting rolls 17 from a bobbin or bobbins 10 driven by a drum 2. The reserve bobbin 35 is held from engagement with its driving drum 36 by a catch lever 39 until the yarn diameter on the lower bobbin 10 has decreased to a size for its axle 12 to depress and then slip by one end of a hammer member 11, 13 which strikes a lever 44 which trips a pawl 5 into engagement with a ratchet wheel 3 secured to drum 2, the pawl 5 being carried on a cam 4. The cam 4 is rotated one revolution and the pawl 5 is then disengaged by a trip'pin 7. The cam 4 operates a follower and lever 46, 24 to pivot, through a bracket 22, the member 18 to prevent the free ends 43 of the yarns 21 from the upper bobbin 35 to the nip of the drafting rollers 17. At the same time the catch lever 39 releases the upper bobbin 35 into engagemnet with its driving roller 36 so that the yarns from this bobbin are then fed to the spinning machine. If the lower bobbins have run out they can be removed and replaced manually by the upper bobbins without stopping the machine and a fresh reserve bobbin installed. If the lower bobbin has not run out completely, or it is desired to change before it is run out by lifting the lever 44 manually, the yarn ends 29 from the lower bobbin 10 are clamped by a clamping plate 27 co-operating with a guide bar 25 (Figs. 7 and 8, not shown) on the member 18. The return movement of member 18 will then break the the yarns from the lower bobbin which can then be removed as before. The bobbins may be of the multiple type feeding a number of separate threads from spool sections simultaneously to separate spindles of the spinning machine.

IPC: F16F9/52
Filed: 1959-05-01
Abstract: 863,595. Hydraulic shock-absorbers. FORD MOTOR CO. Ltd. (Ford Motor Co.). May 1, 1959, No. 14904/59. Class 108(3). In an hydraulic shock-absorber the restricted passages 23 Fig. 2 in the piston 21 or between the cylinder chambers &c. have the effective size varied in response to temperature changes, the apertures 23 being overlapped by apertures 42 Fig. 3 in an annular member 41 which is rotatable in position by a bi-metallic spring 43. The effective shape of the passages 23 may be varied by a fixed plates 28 Fig: 5 having notched apertures 34, 36 with an intermediate arcuate portion 37 arranged to overlap the passage 23 and shaped to produce any required relationship between the damping effect and the temperature change. The bimetallic spring 43 is bent at 44 to engage slots 47, 48 in the piston 21 and collar 29 of the plate 28 and provide a fixed anchorage. The free end of the spring is bent at 49 to engage a slot 51 in a flange 52 of the rotatable plate 41. In operation, on the rebound strokes, the fluid passes through apertures in the valve assembly 24 and thence through the restricted passages 23, and may open a rebound plate 26 against its bias spring 27.

Abstract: 1,000,567. Fluid-pressure brakes. H. TEVES, E. A. TEVES, and M. TAUSEND, [trading as ALFRED TEVES MASCHINEN-UND ARMATURENFABRIK KOMM.-GES.]. April 17, 1963 [April 19, 1962], No. 15067/63. Heading F2F. A braking force regulator for an hydraulic braking system of a vehicle comprises a differential piston having opposed faces subjected respectively to master cylinder pressure and wheel cylinder pressure, a valve passage through the piston interconnecting chambers in which the respective piston faces are disposed and being closed by a valve in the released condition of the brakes, the valve acting as a pressure reducing valve when the brakes are applied with sufficient pressure, a further chamber connected to means, e.g. an air spring, responsive to axle load of the vehicle for determining the pressure above which the valve operates as a pressure reducing valve, and a second valve which is opened by movement of the piston during release of the brakes for returning surplus fluid from the wheel cylinders to the master cylinder reservoir after the first valve has closed. As shown, the differential piston has large and small diameter portions 5, 20 respectively engaging large and small diameter portions of a stepped bore 4 in a housing 1 which is provided with an inlet 2 from the master cylinder, an outlet 3 to the wheel cylinders and an outlet 31 to the master cylinder reservoir. A cap 24 bolted to the housing 1 contains a piston 25 which abuts the end 22 of the piston portion 20, piston 25 and the cap 24 forming a chamber which is connected to an air spring of the vehicle. The force acting on piston 25 due to the pressure in the air spring is balanced by a compression spring 26 so that only under heavy vehicle loading is the differential piston held in the position shown during application and release wherein valve 6 is held off its seat in an insert 11 by contact of extension 18 with the adjacent end wall of the housing to equalize pressures in the wheel cylinder and master cylinder via passages 9, 10. Normally, under light vehicle loading, the differential piston moves to the right on reduction of master cylinder pressure, whereby spring 19 closes the valve 6 and the fluid in the wheel cylinders is exhausted by a shoulder of the piston part 5 moving past a seal 28 so that the fluid can pass between reduced diameter piston portion 32 and the wall of bore 4 into the outlet 31. During subsequent application of the brakes the differential piston again moves to the left, the ratio of wheel cylinder pressure to master cylinder pressure being determined partly by the ratio of the areas of piston faces 21, 15 and partly by the vehicle loading. When the forked end of insert 11 abuts the end of the housing, this ratio is maintained, valve 6 acting as a pressure reducing valve permitting fluid to flow from the master cylinder through passages 9, 10 to the wheel cylinder outlet 3.

Title: Device for x-ray spectrophotometry
IPC: G01N23/08
Filed: 1971-05-14
Abstract: 1332370 X-ray spectrometer MEDINOVA A B 14 May 1971[21 May 1970] 15124/71 Heading G1A [Also in Division H5] An X-ray spectrometer for measuring more than one constituent in a sample comprises an X-ray tube supplied with a high voltage cyclically varying between two levels to provide emission at two different, alternating wavelengths and a filter system arranged to switch in filters in synchronism with the high voltage variation to define more accurately the separate wavelengths. The apparatus of Fig. 1 is suitable for the determination of bone salts and soft parts in a part of the body 5 which may be inserted in the measuring beam. The tube 2 is supplied with a high voltage comprising a pulsating component superposed on a substantially constant D. C. level via transformers and smoothing circuits etc. 1. The tube has a water cooled tungsten target which omits X-ray radiation at an energy proportional to the applied voltage. The emission from the tube is arranged to provide a measuring beam towards detector 6 and a reference beam for compensating for fluctuations in X-ray source intensity to detector 6a. In the path of both beams is the filter system comprising a rotary sector disc having two opposite sectors of thorium and two of samarium. The rotation of the disc is monitored by electrooptical arrangement 3 and is arranged to synchronize the thorium filter with the high voltage part and the samarium with the low constant part of the X-ray supply waveform. In operation, without the test body 5 in position, the positions of wedges 4a, 4b of simulated bone salts and soft tissue, respectively are adjusted to equalize the intensities of the two different alternate energies in the measuring beam, and also to equalize them with the intensity in the reference beam. Bone salts absorbers 7, 4e and soft tissue absorbers 7a, 4f are provided to aid thus calibration. On insertion of the test body, the output of detector 6 changes for both energies. The detector output corresponding to bone is channelled by gating circuits 8 to a first differencing circuit (with the corresponding reference channel signal) and that corresponding to soft tissue to a second differencing circuit, Fig.3 (not shown). The signals comprise pulses which are rendered all of equal amplitude, the pulse rates being representative of intensity (effectively the number of pulses detected during each half cycle). These digital differences are converted by D/A converters to supply motors 4c, 4d to drive the wedges 4a, 4b to balance the intensities once more. The necessary displacements of respective wedges represent the amounts of the respective constituents.

Abstract: 515,213. Starting prime-movers. HILL, H. E., BURBIDGE, L., and BLACKSTONE & CO., Ltd. May 23, 1938, No. 15350. [Class 38 (iv)] An internal - combustion engine 11 is started by an electric motor 17 through the intermediary of an auxiliary engine 12. Closure of switch 30 or switch 28 energizes coil 24 to close contactor 34 and start motor 17 to crank engine 12. A fuel solenoid 20 for the engine 12 is energized simultaneously with coil 24. After an interval a relay 26 energized through switch 28 or 20, closes contacts 80 to energize a magnetic clutch 15 so that the main engine is cranked by the auxiliary engine. A fuel solenoid 21 for the engine 11, and a compression release solenoid 22 to facilitate starting are energized. Under normal conditions the main engine starts and centrifugal contacts 52 thereon open and de-energize coil 24, solenoid 20 and clutch 15. Thus stopping the motor. the auxiliary engine and frees the clutch 15. After a delay, relay 25 opens contacts 83 to de-energize the compression release solenoid 22 so that the engine 11 runs normally. If, however, the main engine does not start a time-delay relay 27, energized through closed contacts 52 and switch 28 or 30, opens its contacts 47 to deenergize coil 24 and stop the motor 17. If relay 27 operates, it also closes contacts 70 to light a warning lamp 29. Contacts 70 may also initiate the starting of a second engine when they close. The main engine stops when the switch 28 or 30 is opened for the fuel solenoid is then de-energized. The switch 30 may be operated manually, by a relay, or by a float or other device which responds to an external condition. The battery 18 may be kept charged by a trickle-charger 19 or the starting motor may act as a generator, when the engine is in operation, to charge the battery and, incidentally, provide energization for its magnetic clutch. 15.
