Title: Improvements relating to safety devices for fly-presses
Inventor: RIDLEY WILLIAM WILSON
IPC: F16P3/00
Filed: 1953-06-26
Abstract: 731,328. Machinery safety devices. BRITISH THOMSON-HOUSTON CO., Ltd. June 26, 1953, No. 17790/63. Class 80 (4); A safety device for a fly-press having a guard 9 movable into a safety position around the tool 5 of the ram 4 and the anvil 3 against the pressure of a spring 22 comprises a lever 23 pivoted at 24 and controlling the position of a jamming roller 35 in a wedgeshaped chamber 36 formed by a surface 38 on the ram 4 and a fixed inclined surface 37. A spring-loaded latch member 27 pivoted at 28 acts on the lever 23 through a hemispherical washer 31 to provide a snap-action over the centre line of pivots 24, 28. When the guard is in the open position shown in Fig. 1, the lever 23 is raised and the jamming roller wedges in the chamber 36 to prevent descent of the ram. If the guard is lowered to its safety position its top surface 10 engages the lever 23 to depress it so that it snaps over into the position shown in Fig. 3, in which the roller 35 is raised clear of its jamming position to allow free descent of the ram when operated by the bar 8. A key member 39 on the guard also engages by a notch 41 a projection 40 on the latch member 27 to hold the guard in the safety position. On the upstroke of the ram a projection 42a on a flexible finger 42 secured to the ram engages the underside of lever 23 and snaps it back to its original position to unlock the guard, which is thereupon raised by the spring 22, and to return the roller 35 to its lower position where it will lock the ram against a further downward movement until the guard is again closed.

Abstract: 515,913. Lathes. SACHSISCHE KNOPF UND BURSTENMASCHINEN WERKE GES. June 15, 1938, No. 17862. Convention date, June 15, 1937. [Class 83 (iii)] Lathes for profile turning buttons &c. with a simple tool which may be of hard alloy or a diamond, have the motion of the tool controlled by two levers adjustable in length, each of the levers co-operating with a separate cam and actuating one of a pair of slides supporting the tool the slides moving transversely to one another and the cam being mounted on a vertical shaft one immediately above the other. The tool 2 is carried on a compound slide arrangement the lower slide giving the longitudinal motion to the tool from a bell-crank lever 25 a roller on the end of which engages a cam 14. The upper slide derives its motion from a lever 21 which has a slotted connection with an adjustable pin carried on a further slide 16 and moved transversely by a cam 15 engaging the roller 17. The first slide has a similar adjustable connection with its lever for varying the effective stroke. The slides 16 and 23 are acted on by springs 27 and 18 respectively to maintain the rollers in engagement with their operating cams. The latter are driven through bevel gears 8, 9, Fig. 1, from a shaft 7 and the gears are connected together so that the whole of the toolmoving gear may be, adjusted through the handle 11 towards or away from the machine spindle.

Title: Improved Device for Cooling the Barrel of a Machine Gun.
Inventor: DEBAUGE HENRY
IPC: F41A21/24
Filed: 1916-12-12
Abstract: 127,282. Debauge, H. Oct, 2, 1916, [Convention date]. Machine guns. - Relates to devices for cooling the barrels of machine guns, especially of the Vickers type, by employing fusible metal as the cooling- medium, and consists in the construction and arrangement described below. A cylindrical steel tube a, Fig. 1, is screwed upon the rear part b of the barrel and at the forward end upon a member d. The barrel being conical, an annular space is left between the barrel and the tube a, and this space is filled with an alloy fusible at a relatively low temperature, which may be the alloy of bismuth and tin described in Specification 126,983. The part of the cooling-device above described remains fixed to the barrel and is dispensed with when the gun barrel is cylindrical. Upon the tube a, or upon the barrel when it is cylindrical, is mounted a radiator composed of a double-walled chamber filled with the alloy, the inner wall e being cylindrical, and the outer wall f shaped to form a series of disks. A nut h and a fixed cheek g on the frame retain the radiator at the rear end, and a member i of the recoil mechanism, together with a cheek j, secure the front end, the whole being strengthened by bolts k.

Title: Improvements in or relating to the automatic paralleling of alternating current systes
IPC: H02J3/42
Filed: 1932-06-24
Abstract: 406,643. Synchronizing. WESTING- HOUSE ELECTRIC & MANUFACTURING CO., East Pittsburg, U.S.A.-(Assignees of Gulliksen, F. H. ; 516, Holmes Street, Wilkinsburg, Pennsylvania, U.S.A.) June 24, 1932, No. 17885. Convention date, June 30, 1931. [Class 38 (iv).] An automatic paralleling system for A.C. systems comprises a paralleling switch 10 energized by a relay 37 controlled by relays 221, 231 which are operated by discharge tubes 22, 23, the tube 22 being controlled by potentials which are proportional to the instantaneous frequency difference between the sources to be paralleled and which are effective to operate the tube and its relay 22<1> at an advance phase angle before synchronism which is proportional to the instantaneous frequency difference. The grid of the tube 22 is biassed by the drop across a resistance 67 which carries the discharge current of a condenser 68 supplied from a full wave dry rectifier 31 which is energized from windings 28, 29 in opposition, which windings are supplied from transformers 27, 26 connected to the sources to be coupled. This provides a bias on the tube 22 which makes it operate at a phase angle in advance of synchronism which is proportional to the beat frequency. The grid of the tube 23 is biassed from a resistance 59 connected across a full wave dry rectifier 33 connected similarly to the rectifier 31 so that it operates at a fixed phase angle in advance of synchronism. The contacts of the relays 221, 231 are interlocked so that the coil 37 cannot be energized unless relay 23<1> operates before relay 22<1> with the result that the relay 37 and hence the switch 10 cannot be operated if the frequency difference is above a predetermined amount adjustable by adjusting the bias of the valve 23. A time delay relay 38 which closes the first time the relay 22<1> operates and thereafter permits operation of the relay 23<1> prevents operation of the relay 37 before the condenser 68 has had time to assume correct control of the valve 22. In a loop system where there is no phase rotation, a time delay disc type relay 93 is provided energized from the voltage difference of the two sources to be paralleled. This relay closes contacts 94, 95 in parallel with the interlocking contacts 48 of the relay 22<1> so as to permit energization of the relay 23<1> and hence of the relay 37 even if the relay 22<1> operates before the relay 231. The paralleling operation is initiated by a push button 16 which operates and holds a relay 15 completing D.C. supply circuits from a supply 39 and the connections between the transformers 26, 27 and 24, 25 through an interlocking relay 21. When paralleling is completed counter contacts 20 on the main switch 10 operate the relay 21 to de-energize all circuits except that of the relay 15. Depression of a push button 17 de-energizes relay 15 which closes contacts 19 to energize a trip coil 14 and open the paralleling switch 10.

Title: Machine tool carriage arrangement
IPC: F16H53/06
Filed: 1977-04-29
Abstract: There is at least one slide (6) for the reception of a tool and this slide is connected to a revolving cam element (14) which imparts motion to it. The cam element has two parallel, continuous cam surfaces (15, 16) arranged on a body of revolution (13). Rigidly mounted on the slide are two guide rollers (9, 10), each guide roller resting continuously against the associated contour (15, 16) during the entire sequence of motion, the forward and reverse movement (7) of the slide thus taking place under positive control. The effective contours of the cam surfaces point approximately in the direction of the axis of the body of revolution, the axis, for its part, running approximately parallel to the plane of motion of the slide. It is thereby possible to reduce the number of coupling elements between the cam contour and the tool slide, this being of considerable importance at high work rates. <IMAGE>

Abstract: 403,979. Attaching knobs to spindles. PYE RADIO, Ltd., Radio Works, and BUTLER, C. E. M., 31, Orchard Avenue, both in Cambridge. June 27, 1932, No. 18085. [Class 44.] An inner element such as a spindle is secured within a hole in an outer element such as an actuating knob by means of a resilient member which engages in recesses in both elements, one element being of relatively soft material and the recess therein being formed by the resilient member itself acting under its own force of restitution. The end of the spindle 1 for adjusting radio apparatus is formed with a flat a and a circumferential groove c and engages a rectangular hole in the adjusting knob 2. The side b of the hole opposite the side against which the flat a engages is formed with serrations parallel to the axis. A strip of spring steel 3 is curved from end to end and has a kink at its centre as shown. This is placed in position in the hole and the end of the spindle pressed in. The kink in the spring 3 springs into the groove c and the edges of the spring bite into the serrations in the side b of the hole, thereby preventing relative axial movement between the knob and the spindle. The spindle is prevented from turning in the hole by internal projections (not shown) formed in the knob which engage the underside of the spindle and keep the flat against the side of the hole.

Title: Process for making a furfuryl alcohol resinous product
IPC: C08L71/14
Filed: 1948-07-09
Abstract: A furfuryl alcohol condensation product, initially soluble and fusible, is made capable of conversion by heat to an insoluble and infusible resinous state by mixing with a plurality of latent catalysts, which although ineffective at room temperature become progressively effective at different threshold temperatures obtained by external heating at a controlled rate.  Catalysts are present in individual amounts sufficient to raise the composition temperature above the external temperature by exothermal heat so that the maximum catalytic effect takes place.  They have threshold temperatures at least 10 DEG  F. apart and are present in sufficient total amount to completely convert the mixture.  Up to 15 per cent furfural may be present and stability must be assured by low acidity.  Specified catalysts are benzene, p - toluene, and p - acetyl benzene sulphochlorides; ammonium benzene, naphthalene, and anthracene sulphonates and disulphonates and ammonia phenol sulphonate; ammonium paratoluene, dimethyl amino benzene and diethyl aminotoluene sulphonates; the aniline salts of benzene and p-toluene sulphonic acid; the pyridine salt of phenol sulphonic acid; glyoxal sulphate; sodium and potassium chlorsulphonates; triethanolamine chloride, aniline hydrochloride or sulphate, ammonium sulphamate, pyridine sulphate or bisulphate; aniline, pyridine or ammonium sulphanilate; trichlorbenzene; phosphoric and maleic anhydrides; ammonium ethane sulphonate; ferric benzene, and toluene sulphonates; ammonium ethyl phosphate, ferric and stannic chlorides, and sodium bisulphate.  The conversion may take place in open moulds or under pressure.  The external heating medium may be heated gas.  The initial mixture may be used as a cement, or a coating or impregnating material, which is then converted.  Fillers, e.g. fibred or sheet asbestos, glass fibres, cotton duck, graphite, slate dust, quartz, or wood flour may be used.  Specifications 595,208 and 627,756 are referred to.
