Title: Method and apparatus for separating solid pieces into fractions approximately according to specific gravity
IPC: B07B1/06
Filed: 1959-01-30
Abstract: 888,212. Separating solid materials. STAMICARBON N. V. Jan. 30, 1959 [Jan. 31, 1958], No. 3435/59. Addition to 852,121. Class 117. In apparatus for separating non-rolling pieces of solid material approximately according to specific gravity, an annular bed of springs 5, Figs. 1 and 2, are secured cantilever fashion to a stationary wall 3, and the free ends of the springs are encircled by a rotaty cylindrical wall 6 having curved guides 10 attached. The pieces are fed from a stationary trough 14 on to a conical plate 12 which is rotated slower than the wall and guides, so that the pieces slide down the plate and are arrested by the guides which control their delivery, from the edge of the plate 12 to the springs. Pieces pass either through the springs to a hopper 19 or through openings 15 in the wall 6 to a trough 18. In Figs 4 and 5 a straight bed of springs 23 are fed with pieces from a vibratory trough or screen 26, and they slide down a plate 21 and are arrested by straight guides 27, 28 reciprocated above the bed and plate, whereby the pieces pass in a controlled manner to the springs. The length of the stroke of reciprocation is preferably equal to the width of the feeder 26. As shown in Fig. 4 the guides are attached to a casing 29 movable along a track 30. In Fig. 6 two beds of springs 34, 35 are fed by a feeder 37 and diverging guides 32, 33 above a sloping surface. Specification 854,856 also is referred to.

Title: Improvements relating to the refloating of damaged submarines and to the saving of the crews thereof
IPC: B63C7/12
Filed: 1925-02-09
Abstract: 229,294. Polouektoff, J. P., Bokhanowsky, I., and Wergeititty, W. de. Feb. 14, 1924, [Convention date]. Leakage, removing; sea-cocks and sea-connections.-A method of refloating damaged submarine vessels consists of isolating the damaged portion of the vessel by means of water-tight bulkheads, introducing compressed air into the sound parts of the vessel, and emptying the waterballast and other reservoirs bv means of compressed air so that the vessel rises towards the surface so as to enable the crew to leave through locks provided at the ends of the vessel and to permit the refloating of the vessel. For this purpose there is provided in the vessel a source of compressed air, for example storage bottles or compressors. Air is drawn down by the compressors through flexible tubes carried on drums at each end of the vessel, the ends of the tubes being connected to floats which in case of accident are detached from the vessel and rise to the surface. Blow-cut valves normally held closed by the external pressure and by springs are arranged at each end of the vessel and connected to piping with openings into each of the compartments of the vessel. Compressors 1, Fig. 1, which may be actuated by electric motors 3 or by hand when necessary, are located at the ends of the vessel and feed air to a pipe 2 which distributes it to the various compartments, the distribution being controlled by valves. At each end of the vessel on both sides are disposed blowout orifices enabling the water to be discharged. Each orifice is fitted with a valve 21, Fig. 4, mounted at the upper end of a pipe 22, the two pipes on each side being connected. to mains 56, Fig. 1, located in the lower part of the vessel on each side and having openings 57. The valve 21, Fig. 4, is normally held closed by the external pressure, aided by a spring 18, but can be opened at will by admitting compressed air to the cylinder 19 behind a piston 20 on the stem of the valve. The valve will however open automatically when the pressure in the compartments is greater than the external. pressure added to that of the spring 18. When all compartments which it is possible to empty have been emptied of water by means of compressed air, the vessel will tend to rise and to assume an oblique position with the damaged end on the bottom, and the crew may escape through thew lock at the higher end.

Title: Separable lead propelling mechanism for pencils
IPC: B43K21/08
Filed: 1921-01-31
Abstract: 165,768. Fischer, H. L. July 2, 1920, [Convention date]. Pencil-holders.-In a screw-actuated pencil the lead-propelling mechanism comprises two members 14, 15, Figs. 1 and 3, removable successively and collectively from the casing 10. The member 14 is threaded internally throughout its length and has a collar 16 at its inner end, the outer end having a closure head 17. The member 15 and lead-carrier 21 function as, and are similar in construction to, the members 16 and 18 described in Specification 165,437. The space between the member 14 and the casing forms a magazine, and as the members 14, 15 are separable, there is no tendency for the extra leads to fall out when the member 15 is partly withdrawn. Fig. 6 shows spring fingers 28 formed integral with the member 15 as an alternative forward end to that member.

Title: Improvements in mould reciprocating mechanism for use in continuous casting machines
Inventor: TAYLOR ALAN KEITH
IPC: B22D11/053
Filed: 1963-01-30
Abstract: 1,040,273. Continuous casting. UNITED STEEL CO. Ltd. Jan. 22, 1964 [Jan. 30, 1963], No. 3849/63. Heading B3F. A mechanism for reciprocating the mould of a continuous casting machine comprises a driving shaft 13, Fig. 4 (not shown), which carries a crank pin 14, located in a block 17 arranged to slide between parallel guides 18 of a rectangular frame 20 secured to a shaft 21. The shaft 21 forms part of a disc 23 in a slot of which slides a block 28. A pin 30 on the block 28 engages a boss 31 on the end of a mould actuating rod 11, which is constrained to move in a straight line by a guide 47 secured to the back plate 39. In operation, the reciprocation of the rod 11 is transmitted to the mould via rod 7 and the lever 4. The oscillatory driving motion produces a quick return movement of the rod 11 and the mould. Manual adjustment is provided to vary the throw of the crank pin 14 and of the pin 30. These adjustments permit the reciprocating speed of the mould to be varied, or the stroke or both. In an alternative embodiment, Fig. 7 (not shown), the mould is oscillated about a fixed centre of curvature to produce a curved billet.

Title: Improvements in shoe-drum brakes
IPC: F16D51/58
Filed: 1951-02-16
Abstract: 681,657. Internal shoe - drum brakes. BRISSON, L. C. Feb. 16, 1951, No. 3864/51. Class 103 (i). In order to obtain equal radial displacements and contact pressures of the brake shoes of an internal shoe drum brake having two or more shoes linked together so as to form a chain, it is arranged that the connecting articulation between two successive brake shoes shall pivot about a centre located on the straight line that joins the instantaneous centres of rotation of the said two brake shoes. As shown diagrammatically, the instantaneous centres of rotation of the three shoes 5, 9 and 14 are respectively O<SP>1</SP>, 02, and O<SP>3</SP>. To provide the operating characteristics required, it must therefore be arranged that the link between shoes 5 and 9 shall pivot on a point A<SP>1</SP> lying on the line O<SP>1</SP>, O<SP>2</SP>. The link between shoes 9 and 15 must pivot about a point A<SP>2</SP> on the line O<SP>2</SP>, O<SP>3</SP> and the yoke member connecting the shoe 14 with the fixed actuator 2 must pivot about the point A <SP>3</SP> coincident with O<SP>3</SP>. Im Fig. 2 is shown a practical example of a brake embodying the above principles. The shoes 5 and 14 are made to pivot in the manner required by formin g arcuate slots 33, 12 and 17 in their webs which are engaged by pins carried on the articulations. The brake would normally operate efficiently for only one direction of drum rotation but so as to provide moderately efficient braking for reverse rotation of the drum, the slot 33 is engaged by pin 5 on the ends of rods 36 and 37, the joint socket 38 of which has a firm frictional coupling with a rod 39, the head of which presses on to cam profile 41 formed on a tail 42 of the yoke 18. For rotation of the drwn opposite to that shown by the arrow #<SP>1</SP> in Fig. 1, the cam profile 41 and finger 39 are pressed together resulting through friction  socket 38 in a displacement of the rods 36, 37. Although the application force on the shoe linings will no longer be equal, there will be a sufficient expansion of the shoes to provide adequate braking for reverse movement.

Title: Improvements in driving mechanism for rotary members
IPC: F16H3/44
Filed: 1940-03-01
Abstract: 539,278. Variable-speed friction gearing. TOLNAI, G. K., and AKTIEBOLAGET G. AREHNS MEKANISKA VERKSTAD. March 1, 1940, No. 3901. Convention date, March 1, 1939. [Class 80 (ii)] In means for controlling the speed of a rotating member by means of step-by-step rotary movements, the rotation of a friction-roller 48, when displaced from the central position on a rotating disc 49, is imparted to a driven shaft through one member of an epicyclic train, and another member of the train receives the stepby-step controlling movements, which are thus superposed upon the motion imparted by the friction gearing. The shaft 47 of the frictionroller has a splined connection with a gear 50, which meshes with a gear 41 of twice the size carrying a planet-wheel 39. The wheel 39 meshes with a sun-wheel 40 on the driven shaft 42 and also with a sun-wheel 38 on a shaft 37, to which the controlling-movements are imparted, e.g. by ratchet-mechanism. A gear 43 on the driven shaft 42 meshes with a gear 44 of the same size formed with a central nut 46, through which passes a threaded portion of the shaft 47. When a short movement is imparted to the shaft 37, the change in velocity of the shaft 42 causes a turning of the nut 46 relatively to the shaft 47, so that the roller is moved outwards or inwards to a new position on the disc 49, and the speed of the roller and that of the driven shaft are altered accordingly.

Title: Improvements in and relating to liquid clutches
IPC: F16D33/20
Filed: 1947-02-10
Abstract: 631,607. Hydraulic couplings. BECKER, J. E. Feb. 10, 1947, No. 3903. Convention date, Feb. 14, 1946. [Class 69 (ii)] In a hydraulic coupling comprising radial blades mounted in an impeller wheel, a torquereducing barrier-member is formed around the inner periphery of the wheel in front of the edges of the blades and orifices are provided in the barrier member which register with the spaces between the impeller blades and openended, liquid conduits positioned between the impeller blades, into which the orifices in the barrier member open. The barrier member, which limits the torque when the runner 12 is loaded and either runs at a slow speed or stops altogether, comprises ring plates 18 with orifices 19 which plates are secured in front of the inner portion of impeller blades 14 and register with the liquid-circulation spaces between the blades. Tapered channel-members 20, which are also positioned in the blade spaces and abut the ring plates 18, have restricted openings 21 so that with the runner 12 stationary, or nearly so, the effective diameter of the liquid flow in the coupling is increased causing the liquid to pass into the orifices 19 and discharge from the opening 21 so preventing free circulation of the liquid and hence the transmission of full torque.

Title: Modified high-frequency circuits for transmitting telephony or like signals
IPC: H04R19/00
Filed: 1929-02-07
Abstract: 328,967. Standard Telephones & Cables, Ltd., and Smith, C. H. W. Brookes-. Feb. 7, 1929. Local circuits for condenser telephones. - A condenser telephone is connected, in a high-frequency circuit, so as to produce a modulated high-frequency current which is then de-modulated without intermediate amplification by rectifiers having unheated electrodes, so as to produce the low-frequency signal current. As shown in Fig. 2, the condenser telephone 1 is connected in series with the high-frequency source 3. a cold-electrode rectifier 2 and an output transformer 4. delivering the low-frequency signal current to a line 5. A high-frequency choke 7 may be connected as shown, and the circuit may be tuned by a variable series inductance. Full-wave rectification is secured in the arrangement shown in Fig. 5, the two rectifiers 2 being oppositely disposed, and the divided primary coil of the transformers being so wound that an additive effect is produced in the secondary. The highfr.equency current is taken by shielded leads 13 from a source 11 which may be remote from the telephone 1. Accidental modulation present in the source 11 is neutralized in its effect on the low-frequency amplifier 10, by feeding rectified energy from the source 11 to a balancing-device 9. which may also include a low-pass filter. In Fig. 7. the high-frequency source 3 is connected across one diagonal of a condenser bridge of which the telephone 1 forms one branch. The rectifier 2 is connected directly or indirectly across the other diagonal of the bridge. In another modification similar to Fig. 5, the condenser telephone 1 is placed in one branch of the circuit and a balancing capacity in the other branch, both branches including similarly-disposed rectifiers. This modification, in common with those shown in Figs. 5 and 7, prevents the high-frequency current from reaching the line 5.

IPC: F16H25/16
Filed: 1962-02-02
Abstract: 934,131. Linkwork; cam mechanism. GLEASON WORKS. Feb. 2, 1962 [Feb. 23. 1961], No. 4138/62. Class 80 (3). In a mechanism 20, Fig. 1, allowing adjustment of the transmission ratio between output and input reciprocating members such as flexible tapes 16, 17 tensioned by a spring 24, the members 16, 17, Figs. 6, 9, are connected respectively to a slide 26 guided for rectilinear movement on a support 25, and a slide 28 guided for parallel movement on the slide 26; the slide 26 has an opening in which a third slide 30 is guided for movement at right-angles to that of the slides 26, 28, the slide 30 carrying a roller 32 engaging an inclined face 34 on the slide 28 and a coaxial or offset roller 35 engaging a stationary straight face 37 whose inclination can be adjusted to vary the transmission ratio. When the face 37 is parallel to the paths of the slides 26, 28 the slide 30 and roller 32 can undergo no transverse movement and accordingly the slides 26, 28 reciprocate in unison, i.e. the transmission ratio is unity. If the face 37 is adjusted to make a larger or smaller angle with the face 34 (Figs. 4 or 5, not shown), the slide 30 is moved transversely as the slide 28 is displaced, thereby causing respectively a smaller or larger displacement of the slide 26. The adjustable face 37 is formed on a member 38 rigid with a shaft 39 mounted in the support 25, clamping bolts 40 which engage arcuate slots 41 in the member 38 being slackened to allow the face 37 to be positioned by an adjusting screw 42 whose nut carries a roller engaging a slot in a flange of the shaft 39. Plates 49, 50 secured respectively to the shaft 39 and support 25 have graduations to indicate the position of the guide face 37. The rectilinear guiding of the slides is provided by rows of alternatelycrossed rollers such as 31, Fig. 6. As shown in Fig. 1, the tapes 17, 16 are wrapped on cylindrical surfaces respectively of an oscillating cam follower 14 and a disc 10 driving the cradle of a bevel gear generating machine, the spring 24 acting through an element 21 to tension the tapes, to hold the rollers 32, 35 against their guide faces, and to hold follower 14 against its driving cam. In a modification, the tapes 16, 17 are replaced by racks engaging pinion teeth on the disc 10 and follower 14. Specification 627,288 is referred to.
