Title: Recording apparatus
IPC: H04N5/932
Filed: 1965-06-01
Abstract: 1,103,699. Recording and playback. MINNESOTA MINING & MANUFACTURING CO. 1 June, 1965 [8 June, 1964], No. 23372/65. Heading G5R. [Also in Divisions G3 and H3] In a tape transducing apparatus of the type in which: a tape has a video signal recorded in a series of oblique tracks and a control signal recorded along one edge; the tape is driven at a constant speed adjacent a head which rotates obliquely at a relatively higher speed; and a pulse signal is generated for each revolution of the head and compared with the control signal to produce a further signal which is used to synchronize the head position with the tape position; means are provided for supplying a vertical synchronizing signal derived from the pulse signal to produce a video output signal suitable to be supplied to an output device. Recording, Fig. 1.-In the record condition video signals are fed via transformer 64 to head 16 and the associated vertical synchronizing signals are separated by stripper 68 and fed to one input of a comparator 79. The other comparator input is fed with pulses produced once per revolution of head 16 by means of a transducer 81. The output signal resulting from phase differences between the two pulse trains is fed to a brake motor 39 to adjust the speed of rotation of the head 16 relative to the tape 10. The vertical synchronizing signals are also recorded in a longitudinal track by means of head 21. Audio signals are recorded similarly by head 20. Playback, Fig. 2.-In the playback condition the synchronizing signals recorded on the tape are utilized as one input to the comparator and the output from transducer 81, which forms the other comparator input, is also fed to a unit 106 to re-insert vertical synchronizing signals in the video signal fed to an output device 107. Unit 106 includes a number of clamping circuits, Fig. 4 (not shown), which blank out the video signal at the edges of the tape, and provide appropriate levels for the synchronizing pulses.

In a method of preparing plasticized synthetic plastics composition the raw materials are worked up in a mixing drum in which the mixing tools rotate at such high speed that plasticization is achieved through the frictional heat. An apparatus, Fig. 1, comprises a mixing drum in two parts 1, 2 hinged at 19 for opening, and having a charging hopper 5 with sliding inlet closure 7 and a discharge door 10, all operated by pneumatic cylinders 20, 9, 13 respectively. The mixing tools 4 are smooth and sword-like and have twisted outer ends, and are rotated by the shaft 3 at such speed that their ends have a linear velocity of 25-40 m./sec. The number and width of the tools is such that they sweep 50% or less of the drum inner surface. Discharged material is guided by a baffle 17 on to an endless belt conveyer 18 delivering to e.g. a calender. In another embodiment, Fig. 2, the mixing drum 22 has a filling cover 26 which in the position 26a forms part of a discharge channel 27 through which plasticized material is discharged by centrifugal force with a cooling drum 28 having a jacket 30.

Abstract: 1339984 Disc brakes; wear adjustment KNORR-BREMSE GmbH 19 April 1971 [13 March 1970] 24114/71 Heading F2E A spot type disc brake has one brake shoe 3 fixed to a movable brake housing 2 and the other brake shoe 4 actuatable either by pressurization of a plurality of brake cylinders 5 arranged on a circle or by rotation of threaded spindle 8 in a sleeve 7, a play-adjusting ring 12 being operable to adjust the position of the sleeve 7 during pressurization of the cylinders 5 to thereby compensate for brake lining wear. The sleeve 7 has a flange 7<SP>1</SP> which extends between the brake shoe 4 and the cylinders 5 and a flanged ring 17 formed with an abutment surface 17<SP>1</SP>, which, with the brake in the released condition, is spaced a distance 18 from the ring 12: the ring 12 is formed as a multi-port bush with an internal circlip 13 and an external sawtoothed thread 14 meshing with a threaded bore in an insert member 14<SP>1</SP> which is fixedly held in an opening in the brake housing 2. A spring 11 biases the sleeve 7 away from the disc 1; as shown, this spring 11 is supported between the ring 17 and the ring 12 but it could be supported on the insert member 14<SP>1</SP> or on the housing 2. With the brake in its released position an outer surface portion 16 of the sleeve 7 bears against a corresponding surface portion of the ring 12 but when the cylinders 5 are pressurized pistons 6 acting through flange 7<SP>1</SP> move the brake shoe 4 towards the disc 1, the shoe 3 being applied by reaction, and thereby the sleeve 7 is moved towards the disc 1. If the clearance 18 is taken up, because of lining wear, the abutment 17<SP>1</SP> will cause the ring 12 to be displaced towards the disc 1 against the force of the circlip 13 and because of its thread the ring 12 will stay in this position. The spindle 8 which is actuatable by rotation of a lever 9 maintains its position constant with respect to the back of brake shoe 4.

Class 40 (4) In a multi-channel communication system employing two paths for the conveyance of frequency-multiplex signals in one direction between two terminals, the upper sidebands of a number of carriers carry the intelligence of the channels being transmitted over one path, and the lower side-bands formed by modulating the same carriers with the intelligence on the channels proper to the second path, are transmitted over the other. The paths may comprise two pairs of a multi-pair cable or may be two separate bands in a wide frequency range. In the transmitter the channels are connected in series and applied to the line through a cathode follower and in the receiver the channel filters, which are designed to suppress the unwanted side-band by 20 d, b., are connected in parallel. The system permits the use of paths having inferior performance as far as cross-talk is concerned. The carrier frequencies for a second system in inductive relation with the first system are chosen to lie midway between the carriers of the first system so that the cross-talk, if present, is inverted and appears only as noise.
