Abstract: 1,130,474. Filling capsules. SANKYO CO. Ltd. 13 March, 1967 [15 March, 1966; 21 Nov., 1966], No. 11778/67. Heading B8C. When a capsule falls from a hopper 10, Fig. 3, into vertically aligned cylinders 8, 9, its cap is retained by a flange 20 in cylinder 8 whilst its body falls into cylinder 9 to rest on a suction pad 30, the cylinders being mounted on continuously rotating heads 2, 3. As the heads rotate, both the cylinder 9 and pad 30, which slide vertically on cam-tracks 24 and 35 resp. slide downwards until the top of the capsule and cylinder are flush with the surface of the head 3. When the cylinder passes under a feeder (36), Fig. 4 (not shown), powder, agitated by a vibrating plate, falls into the capsule, Fig. 9c. Plungers 42 then compress the charge, Fig. 9d and the capsule is topped-up at a further filling station, 9e. Surplus powder is wiped from the capsule body when the heads rotate past a stationary brush (53), Fig. 7 (not shown), and cam tracks 24, 35 urge the cylinder and pad upwards. A lid 55 is swung downwards by a cam-track 54 to cover the end of cylinder 8 and the upwards movement of the pad and cylinder 9 continues until the body and cap of the capsule are united, Fig. 9g. During further upwards movement of the pad the capsule is ejected. The ejection may be facilitated by applying pressure to the pad to blow the capsule off. In a modification to the filling station, Figs. 10, 11 (not shown) powder, distributed on the surface of the head 3 is lightly pressed into the cylinder by a roller (65) and compressed by a second roller (66). The capsule may be similarly topped up.

Title: Automatic stereoplotting apparatus
IPC: G01C11/00
Filed: 1971-04-28
Abstract: 1340568 Photogrammetry ITEK CORP 28 April 1971 [19 May 1970] 11779/71 Heading H4D In automatic photogrammetric apparatus (Fig. 1) of the kind described in Specification 1,317,546, the sudden incidence of the scanning beams on parts of the respective stereophotographs representing terrain rapidly change in height can result in a loss of correlation and the retention in the scanning of the X parallel data pertaining at the time of loss can result in a prolonged loss of correlation. The present Specification therefore proposes that a decrease in strength below a threshold of the X and/or Y correlation signal causes the scanning beam of one C.R.T. to describe, relative to the standard raster scan of the other C.R.T., on oscillatory scan, Fig. 5, either side of the normal path 122 until the strength of the correlation signal increases above the threshold. The condition responsive circuit 50, track and hold integrator 56 and raster search system 53 which detect the decrease in correlation threshold and cause the search scan of Fig. 5, are shown in detail in Figs. 3, 3a. The X correlation signal at 45 and the Y correlation signal at 46 are both tested for level. The decrease of the X correlation signal alone causes a signal on line 54 after a delay # 1  set by 103 whilst AND gate 106 causes the more serious decrease of both the X and Y correlation signals to give a signal on line 54 after a shorter delay # 2  set by 107. The signal on line 54 gates the square wave output of oscillator 112 through 111 to an integrator 115 which generates the triangular search scanning waveform, Fig. 4 (not shown).

Title: An improved process for preparing wooden surfaces for glueing
IPC: B27G11/00
Filed: 1942-10-24
Abstract: 560,823. Wood cutting and working; filing. LANG, A. A. D., and GERMAN, H. V. Oct. 24, 1942, No. 11880. [Classes 145 (i) and 145 (ii)] [Also in Group XXII] A method of preparing wood for glueing consists in subjecting the surface to the scarifying or teasing action of members that move along the surface in the direction of the grain, the speed of the members being regulated to produce a hairy surface on the wood. Preferably the member consists of a stiff wire brush or steel wire carding, or a steel strip with sawlike teeth on one edge may be wound on a roller with the teeth projecting radially outwards. The method may be used in making airscrew blades or other laminated wooden articles particularly when compressed wood is used. The method may be carried out on a machine comprising a table 17, an endless chain conveyer 18 driven by a motor, and a scarifying or teasing roller 13 covered with wire carding. The table and conveyer are mounted in a frame 16 which is pivoted on the spindle of the driving sprocket 19 and can be raised and lowered by cams 23 to adjust the distance between the roller 13 and the table 17. A roller 14, also provided with wire carding, is used to engage and clean the wires of the roller 13. In use, a wooden board,is placed on the table 17 and its leading edge is pushed beneath the roller 13. The wires tease the surface and also propel the board along the table and keep it in contact with a cross-bar 32 in the conveyer, so that the speed of movement of the board relatively to the roller 13 is regulated by the speed of the conveyer.

Abstract: 1,038,542. Grinding; turning. H. A. WALDRICH G.m.b.H. March 26, 1963 [April 11, 1962; April 21, 1962], No. 12007/63. Headings B3D and B3T. [Also in Division G3] To maintain the peripheral speed of a rotating body having a diameter which decreases during operation, the angular speed is regulated by directing a jet of fluid from a movable nozzle radially against the surface of the body and using the pressure changes in the fluid to control the nozzle so as to follow the surface at a fixed distance and thereby to operate a control for the angular speed. As applied to a grinding machine, a slide 8 is slidable on a guide-way 5 and has a bore 9 receiving a piston 10 secured to a flange 7 of the guide-way. The end of the bore 9 is closed by a plug 17, and the slide 8 carries a holder 19 connected to a pipe 20 which extends through a guard 23 for the grinding wheel 24 and leads to a nozzle 26 curved to conform with the grinding wheel and having a rim. Compressed air is supplied from a pipe 16 to a bore 11 to act on the face of the piston adjacent the plug 17 and through the pipe 20 to the nozzle. The pressure on the plug 17 urges the slide 8 and nozzle 26 towards the grinding wheel against the back pressure of the air passing between the rim of the nozzle and the surface of the wheel. The slide carries a template 33, 34 which is engaged by a feeler 35 having a rack 36 engaging a pinion 37 connected to a drum 38, cable 39 and weight 40, the pinion also being connected to a resistance controlling the speed of the motor driving the grinding wheel so that, as its diameter decreases, its rotational speed increases to maintain its peripheral speed constant. In another embodiment, the nozzle 44, Fig. 5, consists of a row of holes and is connected by a swan neck to the pipe 20 which is connected by a passage 49 to the bore 48 on the annular side of the piston 46. The air pressure from the pipe 16 is connected directly to the passage 11 leading to the piston face adjacent the plug 17 and by a reducing valve 47 to the nozzle pipe 20 and annular face of the piston, whereby the nozzle is pushed forward by the difference in the pressures acting on the opposite sides of the piston. Other valves may be provided to connect the annular side of the piston to atmosphere or the full line pressure. Coolant may be supplied to the wheel at a point in front of the nozzle area in the direction of rotation so that a uniform layer of liquid covers the grain of the wheel to reduce the effect of the grain of the wheel. The coolant may be used as the fluid supplied to the nozzle. The invention may be applied to a rotating body in a lathe or other machine tool.
