Title: Speed adjusting system for grinding wheel drives and the like
Inventor: NEDRESKI R J
IPC: B23Q15/10
Filed: 1972-11-28
Abstract: 1380753 Grinding GENERAL ELECTRIC CO 28 Nov 1972 [22 Dec 1971] 54837/72 Heading B3D [Also in Division G3] The signal inputs to the control amplifier of the drive of a grinding wheel are modified so that the peripheral speed is kept constant as the diameter of the wheel is reduced by wear. The modifying effect is obtained by measuring the incremental current needed to accelerate the wheel and using this current to modify either the' desired speed signal or the fed back speed signal. In the embodiment shown the fed back speed signal 36<SP>1</SP> is modified by the potentiometer 174 and is compared, as signal 114, with the fixed demand signal 24<SP>1</SP> to produce a signal for controller 18<SP>1</SP>. To effect an adjustment the drive is switched off by opening contacts 22<SP>1</SP> so that wheel 10<SP>1</SP> slows down and motor 160 runs coupled potentiometers 152, 174 to the position shown which corresponds to the speed needed for a full diameter wheel. When the motor has slowed, contacts 22<SP>1</SP> are closed and the motor 14<SP>1</SP> will accelerate following the ramp function output from demand signal 26<SP>1</SP>. Motor current is detected by resistor 44<SP>1</SP> and this voltage is compared with the voltage setting on potentiometer 49<SP>1</SP> which again corresponds to unworn conditions. The output of incremental current signal generator 40<SP>1</SP> charges capacitor 126 which is used to energize motor 160 and run potentiometers 154, 174 to a new position which corresponds to the worn wheel diameter. In the case where the desired speed signal is modified the current generator output is used to reduce a 'program' signal which is added to the actual speed signal and compared with the demand signal to produce the motor control signal, Fig. 1 (not shown). The adjustment takes place when the grinding wheel is out of contact with the workpiece and can occur automatically on operation of a normal start button.

Abstract: 1,137,722. Spanners, screwdrivers. B. MARTINS. 31 Dec., 1965 [1 July, 1965], No. 55480/65. Heading B4W. [Also in Division F2] A rotatable tool, e.g. a spanner or screwdriver, for use with a fastener 10, see Division F2, comprises a mateable portion 42, 44, through which the axis of rotation passes, formed with two pairs of axially extending abutment surfaces 54, 58 and 52, 56, the surfaces of each pair lying in the same plane and facing in the same rotational direction, the planes intersecting along a line on opposite sides of which the abutment surfaces of each pair lie, and the pairs facing in opposite rotational directions. In the figure, the axis of rotation is coincident with the line of intersection, and the mateable portion is formed by recesses 42, 44 connected by a throat 46. Figs. 9 and 10, not shown, illustrate a box spanner (70) having a mateable portion extending from one end with abutment faces (80), (82), and (84), (86) on projections (74) and (76). In Figs. 13 and 14, not shown, a screwdriver has projections (374) and (376) with faces (380), (382) and (384), (386), projecting from one end of the shank. A spanner, similar to that in Fig. 4, is illustrated in Fig. 11, not shown, but the recesses are connected by a section having arcuate faces (94) centred on the axis of rotation. The embodiment of Figs. 17 and 18, not shown, comprises a spanner having projections (747) and (748) which extend axially on each side of the shank with inclined end faces (747), (749), and are formed with abutment faces (752), (756) and (754), (758).

Abstract: 1392488 Sterilizing ampoules NIHON DENSHI KK and TANABE SEIYAKU CO Ltd 1 Dec 1972 [1 Dec 1971 21 Feb 1972] 55650/72 Heading A5G [Also in Divisions A2 B8 and H5] To ensure uniform heating of the contents of ampoules 6a, 6b, 6c as they are conveyed through a microwave irradiation chamber 1a, 1b for sterilisation purposes the ampoules are inclined at an acute angle of from 45 to 75 to the vertical with their heads uppermost and are each rotated about their longitudinal axis so that the liquid in the ampoule does not enter the head during irradiation. As shown, ampoules 6b are located between ribs 9a, 9b of a conveyor 8 on an adjustably inclined conveyor support 7 so that as the conveyor 8 moves through chambers 1a, 1b the ribs push the ampoules 6b and cause them to roll on the support 7. Plates 10a, 10b of the conveyor prevent the ampoule 6b falling off. The conveyor may be formed as a flat plate with slots to receive the ampoules which are driven by upstanding walls of the plate (Fig. 4 not shown). The support 7 may move in the opposite direction to the conveyor 8 to increase the rolling rate of the ampoules. To ensure sterilization of the head of each ampoule the support 7 has a slot 13 spanned at one end by an ampoule head supporting rod 14. When the ampoules emerge from the irradiating chambers 1a, 1b a guide rod 12 pushes the base of an ampoule upwardly so that the head is supported by the rod 14 at a position below the base to allow hot liquid, at sterilizing temperature, to enter the head. The slot 13 may be replaced by an inclined recess in the support (Fig. 6 not shown). Each irradiating chamber 1a, 1b may have a separate source connected at 2a, 2b and a separate water load 3a, 3b. Alternatively the wave guides 1a, 1b may be fed in series from a single source.

Abstract: 1500130 Permutation lock QUALIDUX INDUSTRIAL CO Ltd 26 Sept 1975 [24 Dec 1974] 55789/74 Heading E2A A permutation lock is made up of a plurality of elements 1, each of which comprises a housing 2 with a dial member 10 rotatably mounted in it. The dial member 10 has splines 11 engaging in recesses 12 of a pressure plate 13 which is also engaged by a bolt 25 with a tongue 25b. The bolt has splines 26 engaging angularly disposed grooves 27 in plate 13 (Fig. 3). Keeper 3 has holes 30 so arranged that tongue 25b can pass through it only when the tongue has the correct angular setting. A plurality of such elements 1 may share the same housing 2 and keeper 3. The combination may be changed by forcing bolt 25 against spring 28 so that splines 26 clear plate 13 and then rotating the dial. Detents 22 can be used to indicate the position of the dial by cooperation with dimples 23. The lock may be combined with a latching arrangement as shown in Fig. 1. Housing 2 is pivoted to keeper 3 via pivots 8 and 9 and linked to latching member 44 bearing hook 45 (Fig. 5 not shown) so that moving the lock housing 2 into engagement with the keeper enables the hook to slide into a position where it engages another hook 46 secured to another element. This enables two elements e.g. sides of a bag (Fig. 7 not shown) to be locked together.

Each conveyer comprises transverse slats 16 forming an endless belt, the slats being supported by carrier members 10 and rails 12. For tilting the slats, a control rail 18 is movable transversely and, in the conveyers 6, 8 has a section 20 to cause all the slats to tilt along a portion of the conveyers. The conveyers are driven at the same speed and when an article is transferred from one conveyer to another by tilting the slats, substantially no change in longitudinal velocity of the article occurs. In a modification, the articles may be moved laterally by an endless belt device 32 driven at the same speed as the conveyers and mounted on a cylinder 34. Such a device may be used when the conveyers are of the driven roller type. The apparatus includes destination code means which advances in synchronism with the conveyers and operates to divert articles at selected positions along the sorting conveyer. In Fig. 3, articles may be diverted from the sorting conveyer 2 on to further conveyers 3 also provided with destination code signals which follow the articles.
