Abstract: 1,051,820. Windscreen wipers. ROBERT BOSCH G.m.b.H. Nov. 19, 1965 [Nov. 20, 1964], No. 49136/65. Heading A4F. In a windscreen wiper installation in which a wiper blade is oscillated by a motor via a rotary crank, a connecting rod, and a rocker arm having a pin engaging a slot in the connecting rod, a pawl is provided on the connecting rod for securing the pin against displacement in the slot, and the pawl is displaceable by means of a stop member into a position for releasing the pin whereby the wiper may be temporarily stopped whilst the motor continues to run. The temporary stopping may be effected periodically to produce an intermittent wiper action, or it may occur during the switching on and off of the wiper installation to cause one of two or more wipers with overlapping wiping zones to start later and to stop earlier so as to prevent collision of the wipers in the common overlap zone. In the embodiment illustrated an electric motor 2 drives through a worm drive 3, a crank 4 articulated by connecting rods 5, 7, respectively, to rocker arms 6, 8 operating wiper blades 15, 16 (not shown). The rocker arm 8 carries a pin 22 engaging in a slot 21 in the connecting rod 7 so that on starting the motor 2 the wiper blade 16 operated by the arm 8 remains stationary whilst the wiper blade 15 moves to its inner reversing position. During this movement the connecting rod 7 moves relatively to the pin 22 until the latter is engaged behind a coupling pawl 23 carried by the rod 7, further movement of the latter actuating the arm 8 and the wiper blade 16. On opening the manual switch 43 (Fig. 4, not shown) controlling the wiper motor 2, an electromagnet 32 is de-energized to permit a stop pin 33 to be spring pressed into the path of the pawl 23 to release the latter from the pin 22. The wiper blade 16 is then halted in its counter-position and a switch 34 in the motor circuit is opened by the pin 22. After a further half revolution of the crank 4 the blade 15 reaches its outer position and a parking switch 44 (not shown) embodied in the worm drive 3 is opened to stop the motor 2.

Abstract: 1,230,686. Semi-conductor devices. RCA CORPORATION. 2 July, 1969 [9 July, 1968], No. 33454/69. Heading H1K. A plurality of semi-conductor devices are produced from a wafer by forming two junctions spaced by a distance greater than that required in the final device, forming grooves in both faces of the wafer to a depth sufficient to penetrate the adjacent junction, redistributing the impurities to decrease the spacing between the junctions, depositing passivation material over the exposed edges of the junctions in the grooves, and dicing the wafer along the grooves. A plurality of NPN trigger diodes, Fig. 1, are produced in a wafer of P type Si by forming shallow heavily doped N type surface layers (14<SP>1</SP>, 18<SP>1</SP>) by diffusing-in phosphorus or by epitaxial deposition on the wafer, etching or sandblasting a pattern of orthogonal grooves (42) in both faces of the wafer to subdivide the N type surface layers, and heating to diffuse impurities from the surface layers deeper into the wafer to reduce the spacing between the junctions 20, 22 which still however emerge in the grooves. The surfaces of the grooves are passivated by growing a layer 28 of SiO 2  over the whole of both surfaces by decomposition of silane (SiH 4 ) or by heating in steam, covering the oxide layers with layers 30 of borosilicate glass, and removing the passivation layers from the flat surfaces by sandblasting through a mask. The exposed faces are then coated with Pb over a plating of Ni to form electrodes 36, the wafer is diced along the grooves, and the individual devices are encapsulated. The redistribution of the impurities may occur during the thermal oxidation step if this is used, or by a separate step before or after production of the passivation layers. The semi-conductor devices may also comprise transistors.

Abstract: 1,232,030. Drying and heating coal. SIMONCARVES Ltd. 25 Oct., 1968 [31 Oct., 1967], No. 49383/67. Heading F4G. A process for the treatment of coal to render it suitable for use in coke ovens comprises the steps of thermally drying and heating coal of a size not greater than 1 inch, separating coal which is larger than required from the remainder of the dried and heated coal, crushing the coal which is larger than required and recycling the crushed coal to the drying and heating step, removing relatively fine coal dust from the coal from which the larger than required coal has been separated, passing the relatively fine coal to a bunker and passing the coal from which the relatively fine coal dust has been separated to the bunker. In the embodiment shown coal is crushed by crusher 14 to a size not greater than 1 inch dried, heated in flash-drier 19 (or fluidized bed drier) and elutriated in elutriator 22. Coal of a size greater than # inch is passed to crusher 20 and returned to drier 19. Coal dust is removed from the coal by cyclone 24 and passed to cyclones 26 for removal of waste gases therefrom. The separated coal is further dried and heated in flash-drier 28 and passed via cyclone 30 to bunker 27. The coal dust from cyclones 26 is mixed with oil from line 32 and then passed to bunker 27. The coal may be passed from bunker 27 to hoppers of car 33 which charge coking ovens.

Abstract: 1,232,792. Endless conveyers. APPARATENBOUW " MOBA " N.V. 17 May, 1968 [19 May, 1967], No. 23536/68. Heading B8A. An apparatus for successively discharging containers I comprises discharge abutments 10<SP>1</SP>, 10<SP>2</SP>, which can be brought into and out of the path of a discharge member 9 of each container I, and a control member 15 on each container I for successively bringing the discharge abutments 10<SP>1</SP>, 10<SP>2</SP> into the path of the discharge members 9 of successive containers I, each abutment 101, 10<SP>2</SP> being set following the operation of the discharge member 9 of the directly preceding container I by the control member 15 of the preceding container. As shown, a series of oonveyer container carriers I of the type described in Specification 1,151,603 and each carrying a single egg 5 are successively discharged into rows of recesses of egg-trays 48. The latter operation is described in Specification 1,232,793. When a conveyer 37 moves the next vacant row of a tray 48 into line with the path of the carriers I, the leading loaded carrier moves across the tray until an abutment 9 of the carrier engages a fixed stop 27. This rotates the member I about an axis 11-11 (Fig. 1) and operates the discharge mechanism of a gripper 4 so as to release an egg. The rotation of member I also deflects a roller 7 from a guide rail 8 and results in upward movement of the member I under the action of a counter weight 21. This causes the abutment 15 to upwardly deflect a setting member 16<SP>1</SP> on a sleeve 131. A member 10<SP>1</SP> on the sleeve 131 is thus projected into the path of an abutment 9 on the next following carrier I. On further movement of the carrier the abutment 9 engages the member 10<SP>1</SP> thus causing the egg from this carrier I to be discharged into the second recess of the row. The abutment 15 of this carrier then engages a setting member 16<SP>2</SP> on a second sleeve 13<SP>2</SP>. This causes the discharge of the third carrier and so on. The abutment 15 of the last carrier operates a member 17<SP>1</SP> (Fig. 2) thereby closing a switch 17 in the circuit of an electromagnet 18 (Fig. 3). This releases a drive 19 of a cam 20 which through a follower 21, linkage 22 and cross member 26<SP>1</SP> simultaneously acting on abutments 14 1 -14 4  resets all the members 10<SP>1</SP>, 10<SP>2</SP> &c. back to their non-operative positions. The shaft of the cam 20 carries other cams which cause the conveyer 37 to be stepped forward and to be lifted up into the load-receiving position shown in broken lines. In an article sorting arrangement (Fig. 5, not shown), the main conveyer may feed a series of conveyers 37.

An electromagnetic bi-stable relay has a permanent magnet 22 between two polepieces 20, 24, one of which is connected to a core 26 surrounded by a coil 28 and the other polepiece 20 is connected to a yoke 18 on which a threelimbed armature 10, 12, 14, 16 is pivoted. Pulse energization of the coil 28 in opposition to the permanent magnet flux moves the armature from the position shown to a second position (Fig. 2, not shown) in which limb 14 of the armature engages polepieces 20, 24 and limbs 16 and 12 thereof are spaced from polepiece 20 and the lower end of the core 26 respectively. A changeover contact 38A is held by a finger 39 on the armature limb 14 to engage a fixed contact 38C in the position and is biased to move to engage a fixed contact 38B instead when the armature moves to its other stable position.
