Title: Improvements in cam control gear for the distributing-valves of fluid-pressure reciprocating engines
IPC: F03C1/08
Filed: 1937-12-31
Abstract: 499,688. Engine valve-gear. SCHMIDT'SCHE HEISSDAMPF-GES. Dec. 31, 1937, No. 36217. Convention, date, Jan. 7. [Class 122 (ii)] In a cam valve-gear with hydraulic transmissions, an admission valve is opened mechanically, is held open by liquid, trapped in a cylinder by a cam-operated, auxiliary valve and is closed by spring or fluid pressure under the control of the liquid which, by means of the auxiliary valve, is put into communication with a closing cylinder containing a piston which is lowered under the control of a cam. The engine shown has two cylinders each with separate admission and exhaust valves. The cams for lifting the inlet valves and for controlling the outlet valves are driven by a shaft 3 operated by bevel gearing from the main shaft 4. The shaft is moved longitudinally for reversal by a cylinder 5. A shaft 6 parallel to the shaft 3 controls the closing of the inlet valves. The shaft is driven through spurwheels 7 and sun-and-planet gear 8 so that its angular position relative to shaft 3 may be varied by a hand wheel 9 and gearing 10. In the arrangement shown in Fig. 3, the cylinder 13 of the piston 18 on the valve spindle 19 and the cylinder 15 of the closure-control piston 21 are connected by passages 16. 17 to an auxiliary valve-chest 14 in communication with an oilpressure cylinder and containing an auxiliary valve 20 connected to a cross-piece 26 provided with rollers 27, 28 which engage cams 29, 30 on the shafts 3, 6 respectively. The main valve is opened by a cam 25 on shaft 3 through a roller 24, and a spring-pressed, forked rod 22 provided with a collar engaging a collar on the valve spindle 19. The piston 21 is controlled by a cam 31 on shaft 6. The cylinder 13 has a cooling-jacket 35. After the valve has been raised, the passage 16 is closed to hold the valve. After the piston has been raised to the top of the cylinder 15, the valve 20 is moved to connect the cylinders. The main valve is lowered under the control of the cam 31 through the hydraulic link and the cycle repeated. The cylinders 15 are preferably arranged in a separate casting. A single camshaft 3 may open the inlet valves and operate the exhaust valves, and a single cam-shaft 6 may control a number of closing-cylinders. A construction is described wherein the camshaft 6 is arranged transversely below the shaft 3 wherein the valve 20 is replaced by two valves operated by separate cams on the main and auxiliary cam-shafts respectively. Means for cooling the oil between the two auxiliary valve-chests are described.

Title: Television picture and sound recording system
Inventor: GOLDMARK PETER CARL
IPC: H04N5/84
Filed: 1964-09-04
Abstract: 1,036,029. Recording television signals. COLUMBIA BROADCASTING SYSTEM Inc. Sept. 4, 1964, No. 36330/64. Heading H4F. [Also in Division G5] Picture and associated sound information television signals are recorded adjacent each other on to a continuously moving film 21 by scanning the film transversely to its direction of motion with the beam of a line-scan type cathode-ray tube 17, the sound information modulating the beam for a selected time interval after the termination of the associated picture information in each horizontal scan. Simultaneous composite video signals, including the synchronizing signals, and audio signals are applied to terminals 10 and 11, and the video signal is applied through adder 19 to the tube 17 to intensity modulate the beam of the tube which is in synchronism with the horizontal line picture information. The vertical synchronizing signals are recorded on the film in the intervals between the frames, and amplitude wobble may be imparted to the beam to eliminate the appearance of lines. After the cathode-ray spot passes the end of the picture area during each sweep, the spot brightener 23 increases its brightness to a maximum value and the pulse width modulator 25 converts the audio signal into a width modulated pulse signal which causes the blanking pulse generator 26 to deactivate the spot brightener 23 during the central portion of the sweep across the sound track area thus producing a variable area sound track. Alternatively a single-sided variable-area sound track or a variable density sound track may be recorded. By reducing the rate of film motion a vertically compressed image may be produced. To reproduce simultaneously the associated picture and sound information television signals which have been thus recorded the film is driven past a line-scan type cathode-ray tube 30 and a photo-tube 35, Fig. 4 (not shown), the output voltage signal from the photo-tube being switched between the audio and video outputs by means of signals derived from the horizontal drive oscillator of the cathode-ray tube.

Title: Improvements relating to the mechanical handling of articles, such as packets of sugar and other substances
IPC: B65B35/56
Filed: 1955-12-22
Abstract: 835,239. Packaging machines. BRECKNELL, DOLMAN & ROGERS Ltd., and DOLMAN, H. J. March 22, 1957 [Dec. 22, 1955], No. 36770/55. Class 94(1). [Also in Group XXX] A machine for assembling articles in batches for parcelling, the batches comprising two or more rows, includes means for turning each article of one row through 90 degrees relative to the articles of the other row or rows. In one embodiment for turning the articles of an outer row to produce the assembly of Fig. 1, the articles such as packets of sugar 1 are fed to a conveyer 2 from a filling and closing machine to a dead plate adjacent pushers 5, 6. The packets operate a detector 4 to commence feed by the pushers on to a conveyer 7A passing through a dryer 7. In every five strokes of the pusher 5, the pusher 6 misses a stroke so delivering four packets only to the row it faces. When the packets leave the dryer, the two right hand rows as shown are carried by a conveyer 9 to a further dead plate adjacent a pusher 16. The left hand row is fed forward by belts 12, 13 having different speeds so that the packets on them are turned through 90 degrees before assembling with those of the other rows opposite the pusher 16. The completed batch operates detectors 15 which set the pusher in motion to deliver the batch to a parcelling machine 18 (not detailed). In the other embodiment, packets are delivered as before opposite pushers 51-53, the centre one 52 of which makes only four strokes to the five strokes of the others. Presser plates, Fig. 4 (not shown), engage the top of the packet 1d not being moved at each forward stroke and of the packet 1b during the idling of the centre pusher to prevent their frictional displacement by moving packets. After passage through the dryer 7, the articles are separated by fences the centre one of which has an obstruction 10a which turns the centre row of articles through 90 degrees. A belt 176 moves the adjacent outer row against the turned row and the batch assembles opposite a pusher 136. Detectors 103 set in motion grippers 121 which engage the articles adjacent the batch and move them backwards a short distance while the pusher feeds the batch to the parcelling machine W. Grippers engaging the packet tops, Figs. 7, 10 (not shown), may also be provided. Articles may be grouped in two or more courses arranged as described by collating articles at different levels simultaneously and depositing the articles of one level on those below, or by collating articles in groups in one plane and elevating one group on to another. Change in position of an article may be effected by turning it through 90 degrees and toppling it over sideways.
