Title: Grain shockers
IPC: A01D75/06
Filed: 1925-11-24
Abstract: 261,546. Lofstrand, A. P. Nov. 24, 1925. Shocking-machines.-Sheaves from a binder are carried by a conveyer 82 into a cylindrical receptacle 51 which is slowly rotated, the delivery of the sheaves to the receptacle being controlled by picker fingers 87. The receptacle 51 is carried by pairs of spaced rollers 52, 53 engaging tracks formed by rods 48, 47 respectively, these rods being arranged parallel to each other first in an horizontal and afterwards in an inclined direction, the space between the rods in their inclined direction, however, being greater than that in their horizontal direction. On each side a link 70 connects the container to a rocking arm 72 secured to a shaft 57 provided with a spur wheel 59 engaged by a rack 61 actuated by a rod 65 connected to the strap of an eccentric 42 mounted on a sleeve 40 free on a countershaft 39. The shaft 39 is driven continuously from the main wheel 35 of the machine through a chain 76 and carries a bevel wheel 94 driving a stub shaft 105 through an inclined shaft 97. The shaft 105 carries a cam engaging a shipper lever 112 for a clutch sleeve 110 splined to the shaft 39 and carrying clutch members adapted to be brought into engagement with coacting members 109, 108 secured to the sleeve 40 and a short sleeve carrying a bevel wheel 93 respectively. The wheel 93, when driven, actuates the conveyer 82 and the picker shaft 83 through a shaft 98. In operation, the clutch is engaged with the sleeve of the wheel 93 and sheaves are fed into the receptÓcle 51 until it is full, the receptacle being driven slowly from the picker shaft 83. When the receptacle is full the shaft 105 has been moved to such a position that the cam thereon actuates the shipper lever disengaging the drive to the shaft 98 and throwing in the clutch to the sleeve 40 ; the eccentrics 42 move the racks 61 rocking the levers 72 and drawing the receptacle along its track bars 47, 48 until it reaches the discharging position shown in dotted lines in Fig. 2.

Title: Improvements in or relating to circuits for testing polarised telegraph relays
Inventor: MACFARLANE ALAN
IPC: H04Q1/20
Filed: 1959-09-01
Abstract: 885,569. Measuring short time intervals. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. Aug. 17, 1960 [Sept. 1, 1959], No. 29723/59. Class 37. The " operate " and " release " lays of an e.m. relay are displayed on the C.R.T. by providing two sinusoidal signals 90 degrees out of phase from SG to produce a circular trace, a further signal being provided from SG to an adjustable squaring circuit SC and a phase splitter PS, the output of which drives current through the coil in opposite directions as the signal changes polarity, the arrangement being such that when contact TRI is closed on either side the trace is visible, but when it is in transit the trace is suppressed by means of a brightening circuit BC connected to earth by contact TRI, a monostable circuit MS controlled by one of the phase-splitter outputs applying a short brightening pulse on each current reversal to produce a bright spot on the trace which therefore shows the relation between the current change in the relay coil and the relay response. This applies to a " break " contact set, when a " male " set is tested, the C.R.T. trace is suppressed while the moving spring is in contact with the stationary spring.

Two magnetic rings 32 are secured upon portion 28 of the driven member and enclose a magnetic coil 34. Current is supplied to the coil 34 by way of brushes 60, 62 and conductor rings 64, 66. The peripheral portions 36 of the rings 32 are each provided with a plurality of annular grooves 38 of square or other cross-section. The fluid magnetic mixture 39 is retained by labyrinth seals 40, 42. Cooling fins 24 are provided on the external member 22 to conduct away the heat generated adjacent the inner smooth surface. Specifications 649,553, 671,219 and 677,534 are referred to.

A spring-urged lever 40 is pivoted at 42 to the body 10 and has an opening 58, through which the plunger 38 of the dial gauge passes, and three knife edges 62, 64 and 60 (behind 62), formed to touch an average size body tangentially and acting to guide the body into the gauging position. The lever 40 may be withdrawn from the body by use of a push button 52; and the anvil 22 is screw-threaded to be adjustable. In a modification, the knife edges are carried by a cylindrical member enclosing the plunger 38 and moved axially by a spring-urged forked lever similar to the lever 40. The knife edges may be replaced by flats or by members forming part of a concave surface.

Title: Process for the production of dense, low-porosity or non-porous iron powder from sponge iron
IPC: C21B13/00
Filed: 1962-08-03
Abstract: In the production of dense low porosity iron powder from sponge iron the latter is annealed in uncrushed lump form or in pellets or briquettes under a reducing or inert atmosphere, and is then crushed to the desired particle size.  Annealing should be at a temperature of 1000 DEG  C. or over, and the sponge iron is preferably in the form of lumps of 10 mm. to 50 mm. diameter.

Title: Improvements in or relating to sprayed metal coatings
Inventor: CARMAN ERIC HEWSTONE
IPC: C23C4/02
Filed: 1955-10-22
Abstract: The adhesion of a sprayed coating of heat and/or corrosion-resistant alloy based on iron and/or nickel and/or cobalt to a metal base is improved by first spraying a thin interlayer (preferably 0.001 - 0.002 inches thick) containing about 2-8 per cent of boron in combined form or in solid solution, and heating after the main coating has been applied to free the boron and make it diffuse into the base and main coating. Commercial ferro - boron, or nickel - boron, may be used for the interlayer, and the heating may be carried out in dry hydrogen at 800 - 1500 DEG C., or in vacuo, so that the interlayer as such disappears; the thickness of the main layer should for this reason be not less than five times that of the interlayer. The main coating may itself contain boron, e.g. about 0.04 per cent. The securing together of sintered metal bodies described in Specification 691,983 [Group XXII] may be effected.  The coating of a high temperature steel containing: carbon 0.25 per cent, manganese 0.9 per cent, silicon 0.3 per cent, chromium 20.0 per cent, nickel 16.0 per cent, cobalt 25.0 per cent, boron 0.03 per cent, tungsten 2.75 per cent, molybdenum 2.4 per cent, niobium 0.5 per cent, titanium 0.6 per cent, iron and impurities the remainder, with a boron-containing alloy and then with a main layer of the same steel (such a steel being within the scope of the claims of Specification 746,472) is referred to.

Abstract: 1471773 Moulding foam material BASF AG 9 July 1974 [14 July 1973] 30295/74 Heading B5A Apparatus for the continuous production of sheet foam material from prefoamed plastics particles capable of further expansion comprises opposed endless belts 3 between which the particles 2 are fed and conveyed through a heating zone 5 and a cooling zone 12, the belts comprising alternative gas-permeable and gasimpermeable strips 10 and 11 respectively of the same thickness. Each belt may comprise metal gauze having rubber strips vulcanized therein. Steam is fed to opposed chambers 5 and passes through the belts to fuse and foam the particles. Pressure medium such as air is fed to opposed chambers 8 and passes between the belts and stationary plates 9 of cooling chambers 14 and compensates for the foaming pressure. A seal 15 prevents air flow countercurrent the belts; the air can escape into the atmosphere only in the direction of the belts since the channel along which the belts travel from the chambers 8 and plates 9 is laterally sealed.

[Classes 7 (iii) and 7 (vi).] In an aircraft or other engine provided with a pressure-sensitive device for automatically regulating the maximum output in accordance with the density of the surrounding atmosphere, means are provided whereby the pressure difference acting on the device may be manually varied to allow the automatic control of the device to be over-ridden. Fig. 1 shows the carburetter throttle 9 connected to a relay 12 controlled by a barometric capsule or diaphragm 4 which is connected by a pipe 7 to the outlet of the blower 2. A further connection 14 leads from the barometric device 4 to the atmosphere, or the carburetter intake 15, and is fitted with a manually-actuated valve 16 which, when opened, reduces the pressure in the device 4, causing a greater opening of the throttle. A constriction is formed in the pipe 7 to prevent material loss of pressure from the blower when the valve 16 is opened. The throttle may also be provided with a manual control 10, or a second throttle may be provided for actuation by the pilot. The valve may be connected with the throttle control so as to be opened when the latter is moved beyond the fully-open position.
