Title: Video recording and replay system - permits use of lower tape speeds by employing parallel data transmission
Inventor: SCHMITZ HEINZ
IPC: H04N5/919
Filed: 1978-11-29
Abstract: During recording the t.v. signal is divided into time intervals, typically equal to one line, and read serially and alternately into two groups of n storage locations. Whilst information is being read into group of locations the other group is read out, at 1/n of the read in speed, into n parallel paths on the video tape. For the replay a similar process is adopted. One or other group of locations read in information whilst the other passes stored information at n times the read in speed into the picture reproducing system. The synchronising pulses are typically recorded on a dedicated track on the tape without any intermediate store process. The proposed process enables use of lower tape speeds without loss of picture quality. Typical speeds are 10cms/sec.

Title: Collar attachment to shaft - involves application of axial force to increase shaft dia and trap collar in groove
IPC: B21K25/00
Filed: 1978-12-21
Abstract: A shaft with a permanently attached collar is formed by first machining a circumferential groove in the shaft (1). The shaft (1) is then fitted into the bore of a tubular support (9) so that the groove is aligned with its end face. A ring (5) is placed over the shaft (1) and rests on the support (9). The shaft (1) is then subjected to a very high axial force by means of a hollow punch (8). This axial force causes a diametral expansion of the shaft (1) which traps the ring (5) in the circumferential groove.

Title: Plug with spring-loaded flap - which automatically emerges and pivots through right-angle to cover contact pins
Inventor: HOPPE WOLFGANG
IPC: H01R13/447
Filed: 1979-05-10
Abstract: The plug has a spring-loaded flap (4) that covers its contact pins when the plug is removed from a socket and thereby prevents the user touching the pins. The pins are shrouded by a circular wall. The flap covers the open end of this wall. The flap is acted on by a helical spring (3a) that tends to force it out of a channel along the side of the plug's casing (10). A leaf spring (5) at the hinged edge (6) of the flap causes the flap to pivot through 90 degrees once it has left the channel: the flap thereby automatically covers the pins. The flap is withdrawn by a slide (7) on the outside of the casing. The user moves the slide with his finger or thumb. Another configuration is available in which the contact pins are moved against the action of two crossed leaf springs.

Title: Automatic office machine print mechanism edge control - enables manual setting by using edge control elements with attached sensors
Inventor: KREUTZBURG FRANZ ING GRAD
IPC: B41J29/42
Filed: 1980-04-26
Abstract: The arrangement is for controlling edge positioning of an office machine print mechanism and automatically determines the distance of the edge, which is adjustable using an edge control element (4,5), and feeds corresp. data to the control unit (1). It enables manual edge setting without the unit being affected by a print head search process and without the interruption of smooth operation. The edge position distance data is acquired by signal pick-offs (9,10) attached to the edge control elements (4,5) and operating in conjunction with a signal transducer path (11) consisting of a resistive path connected to a voltage source. The pick-offs consist of sliding contacts which are moved along the transducer path when the edge control elements are repositioned.

Abstract: Prodn. of 2-ethylhexanol (I) comprises catalytic hydrogenation of 2-ethylhexenal (II), or a (II)-contg. material, over a zinc-chromium catalyst which contains additionally copper oxide at 200-290(230-270)deg.C and 100-300 atm. The compsn. of the catalyst is (by wt.) Cu oxide: ZnO: Cr oxide 12.3-54: 11.0-52.2:6-23.2. (I) is useful as a solvent for resins, as a component of additives for fuels or oils, ester lubricants, emulsifiers, flotation agents and extractants, and partic. as a starting material for phthalate esters which are plasticisers, esp. for PVC. These catalysts give yields of 96.97% regardless of the concn. of (II) in the starting material, i.e. higher concns. of (II) can be tolerated in the feed. Both the double bond and carbonyl gp. are hydrogenated so only one catalytic reactor is required; the catalyst retains its selectivity and activity for a long time, and has an optimum temp. lower than for known Al-Zn-Cr catalysts.
