Title: Cartridge type tape-player-recorder
IPC: G11B15/04
Filed: 1972-02-01
Abstract: 1323392 Cartridge tape recorders MOTOROLA Ine 1 Feb 1972 [1 Feb 1971] 4637/72 Heading G5R A latching mechanism prevents the mode of operation of a cartridge recorder from being changed when a cartridge is in a loaded position. In the described embodiment, a protrusion 72 on a pivoted lever 68 is depressed against the bias of a spring 76 when a cartridge 18 is loaded into a receptacle 30 and a protrusion 80 at the opposite end of lever 68 then latches behind/in front of a pin 82, as in Fig. 4/Fig. 5, according as to whether a push button 14 connected to pin 82 has/has not previously been pushed inwards. A switching arrangement 52 connected to button 14 cannot then be changed from an inner RECORD mode position, as in Fig. 4, to an outer PLAYBACK mode position, as in Fig. 5, or vice versa, as long as protrusion 72 is depressed. The risk of inadvertent/accidental erasure of pre-recorded information is thus lessened.

Abstract: 166,185. Salfeld, C. S. March 28, 1918. Valves; valve-gear.-An annular air-compression pump 6 delivers partly into a reservoir 16, and also into a passage 37 leading to terminal admission ports 39. Scavenging-air from the reservoir enters the cylinder through ports 19<a> which, together with the ports 39, are controlled by an oscillating valve 46 actuated by the pressure of the air in the reservoir. The valve is connected to a piston (not shown), which slides in a cvlinder in open communication with the reservoir. At the end of the outstroke, the ports 19<a> are uncovered by the valve to admit scavenging- air, the inlet port 39 to the cylinder and the outlet port 47 from the passage 37 being closed. As the pressure of the scavenging-air in the reservoir falls, the valve is actuated to close the ports 19<a> and to open the ports 39, 47 for the admission of air for the formation of the combustible mixture. A valve 42 in the passage 37 enables part of the charge compressed by tho pump to be transferred to a storage chamber 41. According to a modified construction, the controlling-valve for the ports 39, 19a comprises a pair of sliding pistons of two diameters actuated by the varying pressures of the air in the passage 37 and in the reservoir. A pump of any form may replace the annular pump shown in Fig. 2.

Title: Improvements in and relating to apparatus for stripping card surfaces of carding engines
IPC: D01G15/80
Filed: 1950-03-04
Abstract: 691,186. Carding-engines. COOK & CO., MANCHESTER, Ltd., and MILNES, A. H. Feb. 8, 1951 [March 4, 1950], No, 5520/50. Class 120(i) A carding-engine is provided with a vacuum stripping mechanism comprising valve controlled nozles mounted on a carriage 19 engaging a double screw 24 with oppositely-directed threads extending from side to side of the machine and having a gap 39 at one end of the threads, whereby the carriage is traversed and when at the other end is automatically reversed and when at said one end comes to rest: means are provided for automatically re-engaging the carriage with the screw after a predetermined period of rest for a traverse to the other end of the screw and back again to the position of rest. In the operation of the embodiment shown in Figs. 1, 2. and 5, when the carriage 19 moves to the right it engages a stop 36 and then pushes a bar 26 until a gap 37 falls in a support 27 thus freeing the carriage for further and a return movement: the lateral movement of the bar 26 is transmitted through links 28 and 29 to turn an eccentric 30 so that bevel wheels 32 and 33 disengage thus interrupting a drive through a shaft 31 from the doffer shaft to stop the feed. The carriage automatically reverses and returns on the opposite thread, an arm 38 engaging a stop 35 to reset the bar 26, but at the left-hand end it stops and so remains until a peg 23 is re-engaged with the thread of the screw; this latter section is controlled by a timing mechanism, which completes a circuit to actuate a solenoid 45 movement of the piston 46 of which engages an arm 47 to propel the peg 23. or by hand operation of the piston or arm 47. The reciprocation of the carriage also controls a plate valve 16 a tail 40 of which is operated, between limits defined by wings 41 and 42, by its engagement with adjustable stops 43 and .44 so that as the carriage moves to the right the valve is closed to shut off the nozzles from a suction outlet, but when the carriage arrives at the right-hand end the valve is opened, remains open during the return traverse, i.e. during stripping, and is closed on completion thereof. In a modification, Fig. 7, the plate of the valve 16 is slidably mounted on the carriage 19 and carries bowls 48 which, during the reciprocation of the carriage, engage inclined sides of members 50 and 52, 53, so that in moving from right to left the valve 16 is closed for the first half of the journey and not stripping, and that on the second half it is open and stripping; on the return the valve is closed for the first half of the journey and not stripping, but is open and stripping for the second half: thus the lap is stripped in halves from alternate sides and the arrest of the feed and "piecing-up" are eliminated. More than one member 5.0 may be employed with corresponding members 52, 53 to operate the valve more frequently.
