Title: Automatic search magnetic tape apparatus
IPC: G11B27/32
Filed: 1973-10-19
Abstract: 1443806 Magnetic recording and playback apparatus AMPEX CORP 19 Oct 1973 [31 Oct 1972] 48902/73 Heading G5R A magnetic tape recording and playback apparatus is operative to transport a tape 17, Fig. 1, forwardly at a first speed during recording or playback and at a faster speed for fast wind and rewind, the apparatus having means 45, 71, Fig. 3, for recording a location signal on the tape for subsequent use in repositioning the tape in the position obtaining at the termination of the latest operation at said first speed after a movement from said position, and sensing means 45, 53 conditioned by operation of a fast wind or of a fast rewind selector for sensing said location signal and automatically terminating the fast tape traversal on sensing that signal so that a further operation at said first speed may commence at the approximate location of the termination of the immediately preceding operation at the first speed. Operation of a play/record selector (55a), Fig. 4 (not shown), may cause an A.C. signal generator (71a) to record a continuous location signal on the tape 17 via a transducer head (45a). After the play or record operation is terminated, a rewind selector (41a) rewinds the tape and after a predetermined period of rewind, e.g. 1 sec, a timer (97) connects a D.C. erase signal generator (89a) to the head (45a), the remaining one second long location signal being subsequently sensed to stop fast forward transport. Alternatively, a rewind selector 41, Fig. 3, first connects a location signal generator 71 to head 45 for a period, e.g. 1 sec., determined by a timer 73 and then connects an erase signal generator 89 to head 45 for the remainder of the rewind period, and a play/record selector 55 connects the erase signal generator 89 to the head 45 continuously during playback or record. A manually operable switch 99 disables the automatic location signal recording and search functions and a manually operable switch 101 allows a plurality of location signals to be recorded. The switching circuits may be alternatively arranged to allow the search operation to proceed during fast rewind after location marking during fast wind following termination of a playback or record operation. The location signal may be recorded on a 0À3 mm. wide track on a 12À7 mm. wide video tape. During autothreading of the video tape in a rotating-head video recorder, Fig. 1, a solenoid-operated finger 101<SP>1</SP> strips the tape leader 23 from the supply reel 13, and spring-urged guide followers 39 assist in wrapping the leader 23 around a take-up hub 35 which has a high coefficient of friction surface 145, e.g. of rubber or vinyl.

Title: Hydraulic intensifier
IPC: F01L25/06
Filed: 1970-10-14
Abstract: 1281627 Hydraulic intensifiers AISIN SEIKI K K 14 Oct 1970 [18 Oct 1969 20 Jan 1970] 48914/70 Heading F1P An hydraulic intensifier comprises a housing 1 containing small and large diameter piston portions 5, 6, the piston portion 6 having a bore 7 in which a control valve means 8 can reciprocate to control reciprocation of pistons 5, 6 which serve to change fluid into accumulator 43. Piston 5 defines a chamber 4 in bore 2 of the housing, the chamber 4 being connected to a fluid-pressure source P and an accumulator 43 via ports 51, 41. Between bore 7 and valve means 8 are defined annular chambers 28, 30, 34. Chamber 28 is connected to inlet port 24 in bore 3 via passages 27, 26, 25. Chamber 30 is connected to a chamber 19 in bore 3 via passage 31, and chamber 34 is connected to a reservoir R via passage 35, exhaust chamber 118 and port 40. Three radial ports 20, 22, 23 can be selectively connected via annular passage 45, radial passage 46 and axial passage 53 to a chamber 21 defined between adjacent ends of valve means 8 and piston 6. In operation, pump P supplies fluid to ports 24, 51. The pressure to port 24 is transmitted to chamber 28 via passages 25, 26, 27 and to chamber 21 via port 22 and passages 45, 46, 53. Fluid pressure to port 51 is transmitted to accumulator 43 via chamber 4. At a predetermined pressure in chamber 21, valve means 8 moves to the left opening communication between chambers 28 and 30, such that fluid can flow to chamber 19 via passage 31 to move piston 6 to the right. When the Fig. 2 (not shown) position is reached, chamber 21 communicates via port 22 with exhaust chamber 118 and valve means 8 is urged to the right by spring 10. This opens communication between chamber 30 and 34 and the fluid in chamber 19 is thus exhausted so that pressure in chamber 4 returns pistons 5 and 6 to their original position, Fig. 1. The rightwards movement of the pistons serves to charge the fluid-pressure in the accumulator to a higher pressure than that of the source. The process is continued until the desired accumulator pressure is achieved.

Title: Improvements in or relating to Polymer Compositions formed from Vinylaromatic Compounds.

Abstract: 1,175,261. Vinyl aromatic polymer compositions. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 12 Oct., 1967 [1 Nov., 1966], No. 48976/66. Heading C3P. A polymer composition is prepared by polymerizing a solution of up to 50% by weight of a polyvinyl aromatic compound in the monovinyl aromatic compound in the presence of a prepolymer formed by polymerizing a solution of a polybutadiene rubber in the monovinylaromatic compound to a monomer conversion which is between 10 and 40% by weight. The aromatic compound may be mono-polymerized, forming a first intermediate product, the rubber continuously polymerized, forming a second intermediate product, and these products are fed into one or a plurality of poly. merization zones. Preferably the amount of prepolymer used is between 30 and 60%, by weight of the total reaction mass. The polymerization, after a total monomer conversion of at the most 25% by weight of the equivalent monomer content of the reaction mass, may be carried out in a single-stage reactor in the absence of agitation. The solution of polyvinyl-aromatic compound in monovinyl aromatic compound may be prepared by heating the monovinyl compound to between 90- 140‹ C. to effect the homopolymerization. The prepolymer may be prepared by heating an agitated mixture of the monovinyl compound and polybutadiene rubber under thermal polymerization conditions, resulting in a polymerization rate of at least 5%, by weight, monomer conversion per hour. Alternatively, the prepolymer may be prepared by heating the monovinyl compound and polybutadiene rubber in the presence of a " non-grafting " catalyst, resulting in a polymerization rate of 3-6%. Preferably, the polymerization to form the required composition is carried out by heating at between 100-220‹ C. The preferred vinyl aromatic compound is styrene, and the preferred polybutadiene rubber is a stereoregular rubber having a cis-1,4 content of greater than 20% by weight, and the prepolymer comprises sufficient of the rubber to give between 5-10% by weight of interpolymerized polybutadiene rubber in the product. In the example, compositions of styrene and a high cis - 1,4 - polybutadiene are prepared. A lubricant such as butyl stearate or a white oil may be included in the solution of polyvinylaromatic compound in the monovinyl-aromatic compound and/or the prepolymer.
