Title: Apparatus for changing and playing gramophone records
IPC: G11B17/16
Filed: 1933-03-25
Abstract: 418,583. Gramophones. FREEMAN, A., 47, Bath Road, Kettering, Northamptonshire. March 25, 1933, Nos. 9031 and 28168. [Class 40 (ii).] The turntable spindle of a magazine gramophone is extended to pass through the holes in the records A which are supported, above the turntable, at one part of their periphery by a fixed but adjustable support C and at the diametrically opposite point by a record-feeding helix B. According to a modification, the extension N, Fig. 8, of the turntable spindle may be helical to feed the released record A<1> gently on to the turntable. The helix B is driven through reduction gearing by a rubbertyre friction wheel z which engages the periphery of the turntable, the wheel z being carried by a spring-pressed arm 2, Fig. 6, which rotates in the direction indicated by the arrow so that should an increase of load be thrown on the driving mechanism, as by a jam occurring in the feeding gear, the drive wheel z tends to be thrown out of engagement with the turntable. The helix B may be replaced by a spindle having a number of parallel discs perpendicular to the spindle and gapped at one part of the periphery, so that on rotation of the spindle the records descend step by step.

Title: Improvements relating to anti-icing systems
Inventor: WIXON PHILIP ARTHUR MERVYN
IPC: H01Q1/42
Filed: 1958-03-21
Abstract: 846,038. Aerial housings. MARSTON EXCELSIOR Ltd. March 9, 1959 [March 21, 1958], No. 9l99/58 Class 40(7). The invention relates to radomes and like protective structures for use on aircraft where it may be necessary to heat the outer surface of the structure to prevent the formation of ice thereon. The invention resides in the arrangement of channels in the structure wall through which a heating fluid, preferably hot air, can be passed to heat the outer skin. It is sought to overcome the difficulty presented by the near conical shape of many radomes by regarding the structure as comprising a converging body portion and a nose portion. The body portion is divided into a number of segments and in the embodiments described the channels in each segment are substantially parallel as indicated at 8, 8<SP>1</SP>. Some of these channels continue into the nose portion where they are merged as indicated and provide for fluid flow right up to the nose cap (Fig. 2, not shown) in which connection is made with channels for fluid flow in the opposite direction. Such outflow channels may include channels like channel 11 between body-portion segments which is coupled into channels reaching the segment edge from either side. The channels may be of V-section, as indicated in three positions on Fig. 1, and be faced with a layer 10 of fibre glass bonded at the apices to the outer skin 9 of the structure so that the skin is heated over substantially the whole of its area. A somewhat different arrangement of channels in another embodiment is described with reference to Figs. 3, 4, and 5 (all not shown). Specification 846,037 is referred to.

Title: Braking mechanism
IPC: F16D51/30
Filed: 1939-03-24
Abstract: 526,834. Internally - expanding brakes. SCHNELL, S. March 24, 1939, No. 9334. [Class 103 (i)] A pair of brake shoes in end-to-end relation in a brake drum are applied by two fluid-motors both disposed remote from one pair of adjacent shoe ends one motor being connected with means for applying pressure to this pair of shoe-ends and the other being connected to one of the other shoe-ends, anchoring means for the shoes being provided whereby both shoes and one only act as leading shoes with normal and reverse direction of drum rotation respectively. Alternative mechanical means for operating the means for applying pressure to the pair of shoeends are provided. The shoe 3 is pivoted on a fixed pin 6 and the shoe 4 normally abuts by a shoulder 9 on a fixed pin 8 and on a fixed pin 11. Communicating fluid-motors 13, 14 are integral with each other and with a plate 12<SP>1</SP> through which the pin 6 passes and which is bolted at 12<SP>11</SP> to the back plate. The piston 15 of motor 13 engages, one end of shoe 4 and the piston 17 of motor 14 is connected by forked link 19 to a pair of levers 20 disposed on either side of shoe 3 and pivoted to that shoe at 22 and connected by an adjustable link 26 to shoe 4. Pressure applied to the pistons is thus transmitted to the upper end of shoe 4 and to the lower ends of both shoes and with. the. drum rotating in the direction of the arrow, shoe 3 anchors on pin 6 and shoe 4 on pin 11 so that both shoes act as leading shoes but with the drum rotating in the reverse direction, the shoes anchor respectively on the pins 6 and 8 and thus act respectively as leading and trailing shoes. Alternative means for applying the brakes by the levers 20 comprise a shaft 43 mounted on the back and carrying an external arm 46 connected to a fall-rod 47 and an internal arm 44 having a pin 45 engaging a slotted link 41 pivoted on a pin 31 secured to levers 20 and passing through a slot 32 in shoe 3. The slot 42 in the link 41 permits operation of the levers 20 by piston 17 without disturbing lever 46 The link 41 may be dispensed with, the arm 44 being then formed to engage a roller on the pin 31. Adjustment is effected by turning the pins 6, 8 which are eccentrically mounted in the back plate and by the link 25, 26 of which part 26 screws on the other part and engages a socket 28 in shoe 4. The arrangement is such that adjustment of this link and with it the shoe 3 and lever 20 does not necessitate adjustment of the lever 46.

Title: Improvements in means for adjusting the relative positions of the circular blades ofedge-trimming shears
IPC: B21B31/26
Filed: 1966-03-04
Abstract: 1,092,796. Shearing. SCHLOEMANN A.G. March 4, 1966 [March 6, 1965], No. 9517/66. Heading B3W. In an edge-trimming shear which comprises two co-operating disc cutters mounted on parallel shafts 1 and 2, the shafts run in eccentric bushes 7 and 8 which are rotated to adjust the overlap of the cutters and the bushes 7 and 8 are themselves rotatable in, but fixed axially relative to, screw-threaded bushes 9 and 10 which are moved axially to adjust the clearance between the cutters. The rotation of the bushes 7 and 8 is effected by a worm gear 19 which is driven by a motor (54), Fig. 4 (not shown), and the bushes 9 and 10 are driven by worms 13 and 14 respectively, the worm 13 being driven by a motor (54<SP>1</SP>). Mounted on the bush 7 is a disc 24 which has an eccentricity which is "n" times greater than the eccentricity of the bush 7 and on which rests a rod 25. A second rod 62 rests on the longer arm 60 of a bell crank lever, the shorter arm of which bears against the end face of the bush 7. The vertical positions of these two rods 25 and 62 thus correspond to the angular and axial positions of the bush 7. Associated with each of the rods is a mechanism by which the extent of the adjusting movement can be pre-set, the mechanisms are similar and only the means relating to the rod 25 will be described. The rod (25) passes centrally through and is guided in, a hollow externally threaded spindle (39), Fig. 3 (not shown), and has secured to its upper end a limit switch (41) the operating member of which is positioned to abut a plate (42) secured to the upper end of the spindle (39). The rod (25) passes through a central aperture in the plate. The hollow spindle (39) is received in a nut (34) which is formed externally as a worm-wheel which meshes with a worm (33) on the shaft of an auxiliary motor (31). The motor (31) also drives an impulse generator (35) which is connected to a counting mechanism. Operation.-To vary the overlap of the cutters the motor (31) is started by a " Forward- Reverse" switch on a control desk (38), Fig. 4 (not shown), this switch operating a relay switch 46 which connects the motor to the supply. The motor is allowed to run until the counting mechanism shows that the hollow spindle 39 has moved axially by the desired amount. The adjusting movement of the cutters is thus pre-set and the actual movement of the cutters is initiated when desired by closing a switch (49) which operates a relay switch (51, 52) and starts a motor (54) which drives the worm 19. As the bush 7 rotates the eccentric disc also rotates and the rod (25) is raised or lowered until the limit switch (41) is actuated by the abutment (42) when the relay (56) is actuated to stop the motor (54).

Title: Improvements in and relating to the concentration and purification of hydrogen peroxide by distillation
IPC: C01B15/013
Filed: 1945-04-17
Abstract: <PICT:0590439/III/1> Hydrogen peroxide of concentration up to 98 per cent. is obtained by distilling aqueous hydrogen peroxide solutions under a pressure not exceeding 6 inches of mercury absolute in a climbing film evaporator 2, the solution being introduced at the base of the evaporator at a pH between 3 and 5, and the vapour produced passed into a separator 5, from which hydrogen peroxide vapour is withdrawn as the overhead product and liquid hydrogen peroxide and impurities as the bottom products; the latter are passed through the reservoir 9 back to the evaporator.  The vapour is then passed through a fractionating column 7 where it is subjected to fractional distillation under reduced pressure with the top of the column cooled, and concentrated liquid hydrogen peroxide having a concentration of hydrogen peroxide of at least 75 per cent. weight/weight is removed as the bottom product.  Further concentration may be effected in a second evaporator, 16 and separator 19, the vapour passing overhead back to the bottom of the fractionating column and further concentrated liquid hydrogen peroxide collecting in a receiver 21.  Alternatively, a second fractionating column may be used from which the distillate passes to the first column and liquid residue to the receiver 21.  When making hydrogen peroxide solutions of concentration greater than 90 per cent. the absolute pressure is below 2 inches of mercury. Specifications 445,334 and 546,530 are referred to.
