Title: Improvements in machines for cracking or crushing nuts or other hard substances
IPC: A23N5/00
Filed: 1919-06-13
Abstract: 151,080. Tarrant, H. J. June 13, 1919. Crushers with vibrating jaws; cracking nuts.- Relates to machines of the kind described in Specification 1839/14 and particularly to (1) means for giving an intermittent rotation to the roller after the nuts have been fed 'between the roller and the jaw and before the crushing begins, and (2) means for controlling the feed of the nuts. (1) The roller 21 is intermittingly driven at the required time by an eccentric 38 on the driving-shaft 3 by means of an arm 39 and a pawl-lever 41 carrying a pawl which engages a ratchet 43 on the roller axle. Backward movement of the roller is prevented by a detent pawl 44. (2) The nuts are fed into the hopper 30 by an endless band 49 carrying transverse bars and forming the bottom of a supply hopper 50. The band is intermittingly driven by a belt from the shaft of the roller 21. When the usual shutter 28 opens to deliver to the crushing-jaw the nuts which have accumulated behind it, the flow of nuts from the hopper 30 is prevented by a supplementary shutter 46 operated by a tail 48 on the shutter 28.

Title: Method fof recording spin resonance spectra and a device suited for the purpose
IPC: G01R33/36
Filed: 1972-03-30
Abstract: 1377555 Spin resonance spectrometers SPECTROSPIN AG 30 March 1972 [28 May 1971] 15215/72 Heading G1N In a spin resonance spectrometer, a sample 2 is excited by a sideband of a pulse-modulated R.F., the spectrum is swept by sweeping the pulse modulation frequency, the resulting resonance signals being received in the intervals between the pulses, heterodyned with the R.F. carrier and recorded. In order to keep the amplitude of the exciting sideband constant, either the amplitude of the carrier R.F. and the ratio of the pulse duration and pulse repetition period are kept constant, or the pulse duration and the ratio of the amplitude of the carrier R.F. and pulse repetition period are kept constant Fig. 4 (not shown). In Fig. 1, the carrier R.F. is generated by an R.F.O. 13 synchronized to a master oscillator 14 via a frequency divider 15. The carrier R.F. is pulse-modulated at 16 with pulses from a pulse former 17 swept in frequency under the control of a sawtooth signal applied to the pulse former 17 via a voltage-to-frequency converter 18. The spin resonance signals are amplified in a preamplifier 22 and heterodyned in a mixer 21 with pulses of R.F. from the R.F.O. 13. The resulting A.F. signal is amplified at 23, phase detected at 24 and recorded at 25. The magnetic field is automatically stabilized by an internal reference energized by 36 in a control channel similar to the measuring channel except that the master oscillator 14 controls, through a frequency divider 42, the pulse modulation frequency.
Patent GB-883800-A (GB)
Title: Improvements in or relating to the production of semi-conductor materials
Inventor: RAYMOND FREDERICK JOHN
IPC: C30B11/12
Filed: 1958-05-14
Abstract: In the production of a substantially pure single crystal of silicon or germanium by decomposition of a gaseous hydride of the element at the surface of a molten drop of the element adhering to a solid rod of the element, the rod is shielded from the hydride to prevent decomposition at the solid surface.  The hydride is decomposed at a molecular concentration less than normal, e.g. at reduced pressure, or at atmospheric pressure in admixture with argon.  Silicon may be produced from silane prepared by the interaction of lithium aluminium hydride and silicon tetrachloride.  As shown, silane is admitted to a transparent tube 1 through a pipe 8, is decomposed at the surface of a molten drop of silicon 14 adhering to a rod 11 of silicon, and by-product hydrogen is removed through pipe 9.  Melting is effected by an induction heating coil 13.  Drop 14 is surrounded by a <PICT:0883800/III/1> water cooled hollow annular silver partition 3 which separates tube 1 from a similar tube 2 which houses the silicon rod 11.  The silicon rod 11 is rotated and lowered continuously by means of a rod 12.  The pressure in tube 2 may be adjusted by feeding in an inert gas through a pipe 10.  Initial melting may be effected either by radiation from a metal ring (not shown) itself heated by induction, or by inductively heating the top of rod 12 itself. Specifications 745,698, 827,676 and 829,422 are referred to.
Patent GB-353585-A (GB)
Title: Improvements in and relating to card filing cabinets
IPC: G06K21/02
Filed: 1930-05-20
Abstract: 353,585. Statistical apparatus. BROMELL, M. W., Highway, Nedlands, Western Australia. May 20, 1930, No. 15436. Convention date, May 30, 1929. [Class 106 (i).] Manual card-sorting devices.-In a card filing cabinet, tongues on the cards are held by locking rods operable from a keyboard to release the desired card, the rods being movable transversely to their length and away from the card and there being a movable rod which tilts the released card clear of the rods. This tilting rod coacts with springs, one mounted in each card. Preferably the locking rods are moved longitudinally as well as transversely. Each card 40, Fig. 6, has a recess with sheet metal pieces 41, 42 carrying the spring 43 and has along another edge initially a complete series of tongues 44. For each card all tongues are cut away except those representing the characteristic of the card. In Fig. 6, the tongues shown represent the name L. E. Shapcott. Co-operating with each possible tongue 44 is a transverse bar 13 pivoted at 15 by links 14, 16. Attached to each link 16 is a rod 17 connected by link 18 and bell crank 19, 21 (or shaft 20) to a rod 22 which is linked, through bell crank 23, to a key 24. Hence when a key 24 is depressed the parts take the position of Fig. 8, and the bar 13 is moved longitudinally and backwardly, away from its associated tongues 44. The keys for, say, L. E. Shapcott being depressed, the correct bars 13 are moved backwards to release only the correct card. All other cards are retained, since they have other tongues 44 still locked by unmoved bars 13. The front half of the floor 30 of the cabinet, Fig. 3, tends to pivot downwards under spring pressure and has rigid with it an arm 35 of which the free end rests on a cam piece 34 rigid with a key lever 33 which is connected to an arm 32 on which rests a transverse bar 31. Arm 35 is also connected by linkage 36, 37, 38 to a transverse rod 39. When key lever 33 is pulled forward to the dotted line position of Fig. 3, the bar 31 is raised to press against springs 43, arm 35 follows cam 34 downwards, carrying the cabinet floor with it, and linkage 36, 37, 38 draws delivery rod 39 forward. These combined actions tilt the unlocked card (L. E. Shapcott) forwards ; for other cards, bar 31 merely stresses the springs 43. When a resetting key 29 is depressed it moves a U-shaped bar 25 through linkage 28, 27, to restore all moved bars 13 in their forward, locking positions. Two or more cabinets, as above described, may be superposed on one another or coupled side by side.

Filed: 1966-04-07
Abstract: 1,139,445. Yarns. DEUTSCHE RHODIACETA A.G. 7 April, 1966 [7 April, 1965], No. 15470/66. Headings D1F and D1W. Successive lengths of alternate twist are imparted to a yarn particularly a multi-filament yarn by passing it through a twist producing device 3 operating at a constant speed and direction and alternately lengthening and shortening the length of yarn passing towards the twist producing member, thus the upstream yarn is alternatively left with an excess or deficiency of twist and this remains in the yarn to produce real twist in the delivered yarn which is wound up at a package 4. The lengthening and shortening of the yarn is effected by providing two twist barriers 1, 2 and intermittently operating the one closest to the twist producing member or by having a single twist barrier which is moved back and forth along the yarn.

Title: A new or improved magazine for air gun pellets
IPC: F41A9/64
Filed: 1936-06-04
Abstract: 476,234. Holder for air-gun pellets. DUROSE, C. June 4, 1936, No. 15584. [Class 9 (i)] A holder for air-gun pellets comprises a channel-shaped plate, Figs. 2 and 3, having a base portion 3 and side portions 4 bent to V-shape in section, the waist of each pellet 6 being gripped by the angles of the V-portions. Each end of the base is formed with an extension 7 having a screw hole 8 for attachment of the holder to the stock of a gun. Alternatively, the base is provided on its underside with spring clips to enable the holder to be carried on the gun barrel. Inwardly disposed projections 9 on the side portions 4 prevent the pellets from leaving the holder unintentionally. Fig. 6 shows a modified construction comprising a base portion 12 and sides 13 which are bent inwardly so that their edges engage the waists of the pellets, a spring plate 14 in the base of the channel providing frictional resistance to movement of the pellets. In either construction, only one end of the holder may be open or both ends may be closed and the pellet engaging parts of the holder recessed to permit of the removal of the pellets at any position intermediate the ends. According to a further modification, the holder is made in the form of a slotted tube, the slot being parallel to the axis of the tube and the ends of the tube being closed by squeezing the tube. One or each end of the slot is enlarged so as to permit of the withdrawal of the pellets. In any of the constructions, a spring or spring-actuated plate may be provided tending to move the pellets away from the position at which they can be withdrawn. In another arrangement, the withdrawal opening may be controlled by means of a plate or cover operable by means of an exterior lever to permit of the withdrawal of the pellets one by one.

Title: Improvements in and relating to thickness gauges
IPC: G01N23/16
Filed: 1949-06-14
Abstract: 666,786. Radioactive thickness gauges. BRITISH THOMSON-HOUSTON CO., Ltd. June 14, 1949 [June 19, 1948], No. 15806/49. Class 40 (iii). A periodically interrupted beam of radioactive particles is used to indicate thickness. As shown, radioactive material is contained in a lead casing 6, α-particles being eliminated from the beam by a thin sheet of aluminium foil 11. The #-particle stream is continuously interrupted by a shutter 8 driven by a synchronous motor 9, this shutter, however, is not sufficiently thick to appreciably affect the γ-radiation. The particles pass through the material under test, past the shutter and through an aperture in a shield 10 which protects an ionization chamber 1 from the effects of external radiation. The particles falling on the chamber cause pulses of current to flow through resistors 3, 4 and the voltage developed across resistor 4 is compared with another voltage 180 degrees out of phase developed across resistor 13 by a generator 12 driven in synchronism with the shutter 8. The unbalance of these two voltages is amplified by a tube 16 operated with a low plate voltage to reduce tube noise, by an amplifier 23 and a tube 25. The last tube 25 feeds the diagonal of a ring modulator circuit across the other diagonal of which a centre zero instrument 33 is connected, the deflection of which indicates by how much the thickness is above or below a predetermined datum. This datum is adjusted by preliminary balancing of the apparatus by a slider on resistor 13. In a further embodiment, Fig. 3 (not shown), a single rotating disc interrupts radiation beams from two different sources of the same material, one beam only passing through the sample so that the beams each reach a plate alternately. The plate fluoresces and a photo-cell behind it thus provides two voltages 180 degrees out of phase. The difference voltage is fed to a phasesensitive detector provided with a reference voltage obtained from a separate generator as in the earlier embodiment. The output of the detector may be switched either to an indicating instrument, or for initial balancing of the apparatus to adjust a wedge in one of the radiation paths by means of a servomotor. The Specification mentions several materials which may be used as #-ray sources.

In a method of providing a strengthening girdle 3 around the bulb 2 of a cathode-ray tube, the bulb is pulled into the girdle by a suction cup 7 secured to a flexible plate 6 provided around its edge with spacers 13 and a supple ring 11, the latter forming a seal between the edge of girdle 3 and the tube faceplate, while the space between the bulb and girdle is filled with a hardening filler. The spacers 13 ensure a substantially uniform depression of sealing ring 11 and hence a regular boundary of the filler, while the flexible plate accommodates manufacturing tolerances in the size of bulb 2 and girdle 3. The flexible plate 6 may be of metal, or a pressed mixture of synthetic and fibrous materials, a sponge rubber sealing ring, having closed pores, being detachably secured to plate 6 by a dove-tail joint 12. During the filling process, the plate 6 bears through four supports 14 on templates 4 to which the girdle 3 is clipped.
