Title: Improvements relating to power feed units for tools
Inventor: EWING RALPH
IPC: B23B47/22
Filed: 1949-12-14
Abstract: 676,805. Drilling machines; machine tool details. CLIMAX ROCK DRILL & ENGINEERING WORKS, Ltd. Feb. 13, 1951 [Dec. 14, 1949], No. 32136/49. Class 83 (iii). A power feed unit comprises a cylinder 6 and a working piston 7 which is advanced by compressed air, the rate of advance being limited by the escape of a confined volume of liquid through adjustable ports 48, 50. The liquid passes into a cylinder 30. On the return stroke, compressed air is admitted to the rear of a piston 31 and the liquid is passed rapidly back through a valve 53. The unit is mounted on the feed-spindle 2 of a conventional lever-fed drill 1. A rack 11 on the piston 7 engages a pinion 12 on the spindle 2. The initial position of the drill is determined by an adjustable stop 22 and the initial feed rate by one of a number of pairs of ports 44 which can be brought into co-operation with an appropriate pair of ports 39-43. Advance of the piston 7 is slowed to a feed rate when the ports 39 are covered and, just before the break-through, the port 48 is also covered. A spring 55 prevents air-locks and a screw 56 enables the system to be initially over-filled. An adjustable stop 65 on the shaft 2 automatically reverses the drill at the end of a stroke by striking a projection 66 on the hand-lever 63. The piston 7 may be attached directly to the drill-head, or may be connected to the machine through a flexible shaft.

Title: Improvements in or relating to apparatus including at least one magnetic head for the magnetic recording and reproduction of sound
IPC: G11B15/34
Filed: 1954-11-09
Abstract: 748,004. Magnetic recording and repro ducing apparatus. PAILLARD SOC. ANON. Nov. 9, 1954 [Feb. 2, 1954], No. 32372/54. Class 40(2) In a magnetic sound record transducing and kinematograph apparatus employing a perforated strip record the strip passes over one sprocket wheel, through a picture gate, over two sprocket wheels and a roller controlled by a flywheel, the magnetic heads and rollers being located in the path between said two sprocket wheels, characterized in that the leading one of the two sprocket wheels is ,connected to the driving mechanism through a clutch allowing disengagement during forward drive, a brake also acting on said sprocket to tension the strip causing it to adhere to the roller and magnetic heads and produce more uniform motion of the strip. Fig. 1 shows a side view of an apparatus wherein a sound and picture film F passes over a sprocket 1, through a picture gate, over a sprocket 2, sound heads 5 and 4. a flywheel controlled roller 6, spring loaded jockey 6, and a sprocket 3. Sprockets 1, 2 and 3 are driven via wheels 12, 13 and 16 respectively, Fig. 2, through a helical cut gearwheel 8 which meshes with gearwheel 13. The gearwheel 13 is enabled to rotate independently of the sprocket 2 during a forward drive, owing to the fact that the slope of the teeth is such that gearwheel 13 is pushed away from the clutch disc 25. During a reverse drive, however, the wheel 13 is pushed towards disc 25 so that pins 29 on wheel 13 engage holes 28 in disc 25 and effect a positive drive. Thus during a forward drive vibration from the gearing is not conveyed to the film through sprocket 2, and a steady resistance is applied to the film through a brake pad 30 pressing on the rim of the disc 25.

Abstract: 1382406 Television; multiplex systems HAZELTINE RESEARCH Inc 10 July 1973 [30 Oct 1972] 32839/73 Headings H4F and H4L In a system for compatibly transmitting and receiving both a colour television signal, e.g. NTSC type signal, and one (or more) additional information (add-on) signal within the same frequency band normally occupied by the colour television signal alone, the additional information is transmitted as a high frequency-time product add-on signal having noise-like characteristics (e.g. as a carrier signal phase modulated with a pseudorandom code representative of the additional information) and having its frequency components within the low energy density region of the transmitted colour television signal, i.e. in the region between the luminance carrier and the chrominance subcarrier, e.g. between 1 and 3 MHz. Mutual interference between the add-on signal and the colour signal is minimized due to the noise-like characteristics of the addon signal and its location within the frequency band, i.e. the colour signal is not unduly degraded. The add-on signal is detected at a receiver by means of a matched filter, e.g. a tapped delay line matched filter, responsive to the pseudorandom code. The additional information may be sound or other data such as digital data representative of news or weather information. The colour signal may comprise a "PAL" or " SECAM " (Registered Trade Mark) type signal and the additional information may be transmitted using linear or non- linear frequency modulation, and by line hopping techniques in which a carrier frequency is changed at rapid intervals to cause the transmitted signal to be spread over a wide range of frequencies.
