Abstract: 1,146,410. Magnetic recording and playback. INTERNATIONAL BUSINESS MACHINES CORP. 13 Dec., 1967 [13 Jan., 1967], No. 56948/67. Heading G5R. A relatively low-frequency signal is recorded by a first head on a longitudinal track approximately along the centre of a tape while a relatively high-frequency signal is fed to a second head which repeatedly scans across the tape at an angle to the direction of movement of the tape, the second head being rendered inoperative as it crosses the central track and the edges of the tape. As shown, in a 360-degree helicalwrap television recording and playback apparatus, sound and synchronizing signals are recorded by a double head assembly 44 on two parallel tracks (50, 53, Fig. 7) along the centre of tape 30, while video signals are recorded on slantwise tracks (76, 77, Fig. 7) across the tape 30 by a rotating head 54 moving in an opening 58 in drum 31. Sensors 71, 72 control a gate circuit 66 to disable head 54 as it crosses the central tracks (50, 53) and the edges 36, 37 of the tape. The two fields of a video frame are recorded on either side of the central tracks. The synchronizing signals are used to control the speed of motor 40 driving capstan 39.

Abstract: 1489581 Sliding roofs for vehicles WEATHERSHIELDS Ltd 6 Dec 1974 [22 Dec 1973 25 Jan 1974] 59685/73 and 03462/74 Heading B7B A flexible fabric cover 13 is mounted on transverse members (not shown) which slide in longitudinal rails 3 forming parts of a unitary frame 1 which, together with the cover 13, is installed as a whole in a roof groining 2. The arrangement avoids the individual attachment of separate frame members. As illustrated, the rails 3 have the cross-section shown in Fig. 3. The transverse members slide between inwardly directed flanges 15 and 16, and brackets 14 secure the cover 13 to rail webs 18. Upper outwardly directed flanges 6 rest on and are bolted to the edges of the roof opening. Lower outwardly directed flanges 7 engage the roof head lining. The distance between the free edges of the flanges 7 is slightly greater than the width of the roof opening and the frame is therefore installed in the opening by a process of tilting and slewing. Installation is completed by attaching an angle section member 17 to the front frame member 4. In another embodiment, Figs. 5-7 (not shown), the lower outwardly directed frame flanges are omitted and, after placing the frame in the roof opening, a further frame or a set of separate frame members, is secured to the main frame to clamp the roof and the head lining against the upper outwardly directed flanges of the main frame.

Filed: 1969-12-08
Abstract: 1281710 Mixing apparatus H NIELANDER 8 Dec 1969 [10 Dec 1968] 59791/69 Heading B1C Mixing machine for plasticating rubber and plastics has a cylinder 8 and a piston 32 which is rotated and reciprocated relatively to the cylinder. The piston has bores 33 through which the material is extruded as the piston reciprocates, the bores may be of various configurations (Fig. 14, not shown), and the piston may also have slots or projections. The cylinder may be clamped between end-plates 5, 6, and reciprocated along stationary rods 4 by a hydraulic, pneumatic or screw jack connected to a rod 19, or alternatively the cylinder may be fixed and the piston reciprocated. In this case, the drive motor may also be reciprocated along guides with the piston rod (Fig. 20, not shown) or the drive motor may be fixed and the piston rod rotated through a splined connection which allows relative axial movement (Fig. 25, not shown). The cylinder may be located between the end plates 5, 6 by tie rods passing through axial bores in the cylinder (Fig. 17, not shown). The cylinder may be charged and emptied by removing end caps 35, 36 which are held in place by the end plates. Alternatively, the cylinder may be flanged and protrude through an opening in one end plate (Figs. 22, 23, not shown) so that one end cap may be removed without disturbing the end plates. The cylinder may also have a side wall a supply tube containing a feeding ram or screw (Fig. 24, not shown) to enable material to be added while mixing continues. The cylinder has cooling or heating passages 38 (Figs. 5-10, not shown). The piston 32 and piston rod 10 may also be hollow to allow heating or cooling fluids to be passed through, the bores 33 may then be formed by tubes passing through the hollow interior of the piston (Fig. 4, not shown). Alternatively the cylinder and piston may be electrically heated. The cylinder may be steel, plated, or lined with ceramic material or made of stainless steel. The piston may also be coated with ceramics, and its periphery may be coated with a lowfriction material such as a fluorinated hydrocarbon polymer, or bronze.
