Title: Method of and apparatus for rearranging stacks of partially dried sods of peat
IPC: C10F5/02
Filed: 1965-06-04
Abstract: <PICT:1115541/C4-C5/1> In the air drying of peat an orderly stack of partially dried sods is rearranged by a tracked machine which travels along the length of the stack and has tines 21 carried by cranked levers 2 and inserted into at least one sod (two as shown) in each row in each layer of the stack at a stepped end thereof, the thus pierced sods are then transported rearwardly by movement of a beam 1 carrying levers 2 and suspended from guide tracks 6, 7 and deposited as a loosened stack in the rear of the machine.  The beam 1 is moved by rollers 4, 5 which run along the guide track which is so arranged that the beam 1 in the discharge position is oppositely inclined to its position when sods are being picked up.  In a modification the tines are rigidly secured to a beam and a lost-motion device halts forward movement of the times at the time of their insertion in the sods.  This modification also has means to adjust the transverse spacing of the tines in two laterally spaced sets of tines.

Abstract: 1,186,775. Developing electrostatic images. RANK XEROX Ltd. May 24, 1967 [June 1, 1966], No. 24122/67. Heading G2H. The concentration of toner in developer material is controlled by a photo-cell P1 which in cooperation with a light source L-1 detects the accumulation of toner on a plate 42 across which developer is directed. The plate 42 is a thin glass sheet having a transparent layer of conductive oxide apart from areas 46 and 44. Developer material flows across the plate in the direction of arrow 42, but accumulates on the area 44 which is electrically connected to a supply by a switch 51, 52. The photo-cell P1 is included in a bridge circuit, imbalance of which due to a reduction in the density of the accumulation of toner on the area 44 as a result of toner depletion operates a Schmidt trigger 66 connected to an amplifier 67 which energizes a solenoid 68. Switch S-1 then closes to energize motor M to actuate a device 32 which effects toner replenishment.

Title: Improvements in bronchoscopes and like surgical instruments
IPC: A61B1/267
Filed: 1957-07-31
Abstract: 806,467. Surgical optical instruments. WISBEY, W. E. July 31, 1957, No. 24266/57. Class 81 (2). A bronchoscope has a blade, carrying a lamp, pivoted to a handle carrying a battery, the pivot being such that the parts are readily separable. The blade 11 and the handle 1 are connected at the pivot which comprises a flat tongue 8 engaged between two side members 4, 5 and rotatable on a pivot pin 6. The tongue 8 has a radial recess 9 by which it may be readily withdrawn from the pivot screw but, under normal conditions, it is prevented from moving radially by a circular nut 7 engaging in a corresponding recess in the tongue 8. In order to avoid exposed arcing of the contacts when the lamp is switched on or off the lower face of the tongue 8 is used as a cam which depresses a spring-loaded stud 23 to make contact with the battery terminal. Shortly before the circuit is completed an insulated stud 27 reaches the stud 23 to form the circuit to the lamp 12. Thus the lamp can only be lit with the blade in the raised position and the actual contact is made inside the handle.

Abstract: 603,307. Making wires. SOUDURE ELECTRIQUE AUTOGENE SOC. ANON. Sept. 19, 1945, No. 24294. Convention date, Jan. 19, 1940. [Classes 83 (ii) and 83 (iv)] Covering ; corrugating; jointing by rolling ;  welding.-A method of making a wire or a strip of small cross-section comprises turning a ribbon or band of metal from a cylinder, pleating the band longitudinally, bringing the faces of the pleats together so that they are in contact and then rolling the mass thus obtained to the desired section. A cylinder 2 of the metal is turned so that a tool 3 removes a thin band 4 which is passed through furnace 5 and between rolls 6 and is then corrugated or pleated longitudinally by a series of pairs of rollers 7-11, the faces of the pleats then being pressed together by rolls 12 having their axes at right angles to those of the rolls 6-11. The pairs of rolls 6-11 are provided with grooves of a triangular shape the grooves of succeeding pairs being narrower but deeper. The strip then passes through rolls 14 and final rolls 13 which shape the work to the required profile. Rolls 13 and 14 may be connected to a source of electric power so that the work is heated to welding temperature when it reaches rolls 13. Alternatively the welding together of the contacting faces may be carried out by the rolls 12, the current then being passed through the work from the rolls 6 to the rollers 12 or 13. The rolls 14 and 13 could then be omitted. The latter arrangement also facilitates pleating. Making cored wire.-If desired a wire 20 of a different metal may be fed into one of the pleats between the rolls 11 and 12 to form a core in the completed wire. A high tension cable comprising an aluminium wire with a steel core could be produced in this way.
