IPC: F27B9/24
Filed: 1927-09-20
Abstract: 291,270. Smallwood, A., and Fallon, J. Sept. 20, 1927. Charging and discharging; charges, conveying; cooling discharged materials.-In a muffle furnace for heating metals comprising preheating, heating, and cooling sections v, b, e, the goods are carried through the furnace by a roller-way conveyer, the rollers i in the heating zone being detachably connected to water-cooled driving- spindles j. Th latter have squared ends l, Fig. 4, engaging in the ends of the rollers, and are fitted internally with concentric tubes p, r serving for the passage of cooling water from an inlet pipe q to an outlet pipe s. The tube p is supported by a spigot t engaging in a bearing in the spindle j, which latter carries on its outer end a worm wheel k meshing with a worm m. These worms are arranged on a common motor-driven shaft n, which also drives the rollers u in the preheating section v. To enable goods to be transferred quickly from the section v to the heating chamber b, there is interposed in the driving mechanism for the rollers u a free-wheel device comprising a driving-ring x, Fig. 5, having teeth y engaged by spring-pressed pawls z, which are pivoted on a ring a<1> secured to the roller. The cooling. section e is fitted with idle rollers wand terminates in a hood f extending below the surface of the liquid in a quenching-tank h; the gas produced during quenching passes into the furnace and serves to maintain an inert atmosphere therein. Doors c, d are provided at the entrance ends of the preheating and heating sections respectively, and a series of idle rollers u<1> is disposed in front of the door c to facilitate charging.

Title: Improvements in or relating to portable telescoping masts
IPC: E04H12/18
Filed: 1954-08-25
Abstract: 779,529. Telescoping masts for derricks. MOORE CORPORATION, L. C. Aug. 25, 1954 [March 16, 1954], No. 24755/54. Addition to 763,648. Class 78 (4). When the telescoping upper and lower sections of a reclining oil well derrick have been disconnected the upper section 2, Fig. 6, is supported from the lower section 3 by means which guide the upper section downwardly, so bringing the legs of the upper section out of their normal end-to-end relation with the legs of the lower section as it is telescoped into the lower section, the bottom face of which is open to receive the upper section. As illustrated, parallel tracks 17 on the outside of the tapering legs 8 of the upper section rest on rollers 21 carried by the lower section and the-upper section is prevented from pivoting about the rollers 21 by engagement of rollers 23 on its legs 7 with the flanges of the parallel legs 5 of the lower section. Before the rollers 21 reach the ends of the tracks 17 during telescoping, a pair of rollers 28, mounted centrally on the lower section as shown in Fig. 9, engages an I-section track 29 on the lower section, the transverse braces 30 of the lower section being disposed below its upper legs 8 to avoid interfering with the rollers 28. After the centre of gravity of the upper section has passed the rollers 28 further rollers 33, Fig. 6, carried by a bracket 34 on the lower section, engage the vertical flanges of the legs 5 of the lower section. In the extended position of the mast the rollers 33 engage inclined tracks 32 on the lower section and abutments 19 on the ends of inclined portions 18 of the tracks 17 engage the rollers 21. The tracks 32 are more steeply inclined than the tracks 18 to cause the upper section to undergo a pivoting motion when initially telescoping so that gravity assists the initial telescoping motion. The sections are joined in their extended position by drive-pins passed through inter-engaging forks and tongues 10, 11, 13, 14 on the upper and lower sections. The mast is extended by lines 40 secured to brackets 41 on the upper section and passing around pulleys 42, 43, 44 on the lower section to be joined to a single line operated from the cathead.

Title: Improvements in or relating to arc control devices for liquid blast electric circuitbreakers
IPC: H01H33/98
Filed: 1952-10-03
Abstract: 735,884. Liquid-blast switches. GENERAL ELECTRIC CO., Ltd., and TAYLOR, S. Oct. 5, 1953 [Oct. 3, 1952], No. 24879/52. Class 38 (5). An arc-control device for an oil or other liquid-blast circuit breaker comprises an auxiliary and a main break in series with one another, the respective movable contacts 2, 3 of which co-operate with fixed contacts 13, 14 and 18 in arc chambers 16, 20 comprising stacks of plates and, when bar 1 is lowered, operate either simultaneously or one after the other, the arc at the main break being extinguished both by oil forced downwards by the arc at the auxiliary break and by oil pumped through aperture 23 into the main arcing chamber by a pump 5. The arcing chambers are enclosed by insulating plates 6... 9, side vents (not shown) in plates 6, 7 connecting with lateral vents (not shown) in plates 22 so that the oil forced downwards by the auxiliary arc first strikes the arc radially through openings 21, then axially, and then out radially through the vents in members 6, 7. The contact 2 is mounted on an insulating pillar 12, and contacts 14 and 18 are connected by a metal platform 15. The pump comprises a piston 24 biased downwardly by a spring 27 which is weaker than that of an operating means 4 on the cross-bar which thus moves downwardly a predetermined distance before pump 5 operates. A one-way valve 28 allows piston 24 to pump oil through holes 30 to aperture 23, while a further one-way valve 31 allows upward movement of pistons 24 on raising of bar 1, the top of cylinder 25 being apertured at 33 and 34.
Patent GB-321002-A (GB)
Title: Improvements in and relating to resilient suspensions for motor road vehicles and the like
IPC: B60G11/38
Filed: 1928-08-31
Abstract: 321,002. Brown, D. Aug. 31, 1928. Springs, arrangement of; lateral canting, preventing.-In a motor vehicle having independently and resiliently mounted front wheels, vertical displacements of these wheels are resisted by longitudinally disposed resilient means carried by the chassis frame, while lateral strains on the wheels are taken by transverse rods or equivalent devices connected at one end to the chassis and attached at their other ends directly or indirectly to the stub axles or king-pins. In the construction shown in Figs. 1-3, the radius rods 38 are crossed and are connected at their inner ends to brackets 39 on the chassis 19 and at their outer ends to the lower arms of brackets 12 which are associated with the stub axles 11 and carry the king-pins 13. The king-pins 13 pass through bearings 14 carried by a transverse member 15, and at their lower ends are connected by universal joints to arms 16 fixed on short transverse shafts 17. Also secured to the shaft 17 are short cranks 28 which, in turn, are jointed to longitudinal rods 29 fitted with washers 32 whereby the shocks are transmitted to the resilient devices 34. The latter may consist of springs or pneumatic shockabsorbers or, as shown in Fig. 5, of a series of rubber discs 34 with interposed fibre washers 35 and flanged sleeves 36 of lignum vitae which prevent rubbing between the rod 29 and discs 34. At one end the discs 34 bear against a fixed transverse abutment 30 on the chassis and at the other end against the washers 32, which are adjustable by means of nuts 33. A similar suspension is adapted for each of the rear wheels 40 except that the radius rods 38 are dispensed with, each arm 16 being received at one end in a slot or recess in a depending lug 41 on the bearing of the universally connected rear axle 42 and being associated at the other end with a shaft 17, crank 28 and rod 29, the connection between the two latter elements being an adjustable one. Sudden upward movements of the chassis are resisted by springs 37 located around the king- pins 13 and by rubber buffers 53 mounted on the chassis and adapted to engage the axles 42. In a modification, Fig. 7, the arms 16 are secured to pins 54 having attached leaf springs 53, the free ends of which move in slots in chassis brackets 56.

Abstract: 763,038. Electrical digital-data-storage apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Sept. 6, 1954 [Sept. 9, 1953], No. 25809/54. Class 106 (1). (Also in Group XXXIX] A two-dimensional matrix arrangement of bi-stable magnetic trigger units for use, e.g., in a digital-data-storage apparatus, comprises a low-reluctance plate r formed with recesses which are bridged by trigger elements t of highly remanent material. A magnetic circuit is thus formed around each recess, the circuit including only a small active portion of the trigger element. The losses in such a circuit are less than those in a comparable saturable annular core and a greater recurrence frequency is obtainable. The losses are further reduced if both the plate and the trigger elements are of low electrical conductivity. One arrangement, Fig. 3, has individual trigger elements t and recesses s through which are passed the usual matrix conductors. The trigger elements may be arranged on suitably slotted raised portions of the plate r, Fig. 4, or the plate itself may be formed with continuous slots for the conductors. In such an arrangement, to ensure that the active lengths of the trigger elements t are equal, the corners beneath the latter are cut away, e.g., by enlarging one of the slots p as shown in Fig. 10. The longitudinally aligned trigger elements may be combined in a single strip or all the elements may be replaced by a ferritic single-crystal plate t<SP>11</SP>, Fig. 8, having a preferential direction with respect to its magnetic properties corresponding to the direction of the elements it replaces. The arrangements may be strengthened by backing the elements t or t<SP>11</SP> with a thick plate of non-magnetic material and/or embedding them in protective material such as glass.
