Title: Improvements relating to absorption refrigeration systems
IPC: F25B15/06
Filed: 1961-09-21
Abstract: 912,257. Refrigerating. ARKLA INDUSTRIES Inc. Sept. 21, 1961 [Sept. 26, 1960], No. 33931/61. Class 29. In a continuous cycle absorption refrigeration system of the two pressure type a storage chamber 80a for liquid refrigerant is connected the outlet pipe 64a from the condenser 22a, the amount of liquid refrigerant withdrawn and stored therein depending upon the condenser pressure. The refrigerant is retained in the chamber when the system is inoperative. In the illustrated embodiment the refrigerant is withdrawn from a system having provision therein to supply hot refrigerant vapour from a separator 42a to the evaporator 70a for heating the surrounding air. When used for cooling, refrigerant and extrained absorbent are supplied from the generator 20a, through a pipe 38a, to the separator 42a, refrigerant vapour passing to the condenser and absorbent to a vessel 50a immersed in a liquid heatexchanger 28a. Liquid refrigerant from the condenser collects in a pipe 64a and is supplied to the evaporator through an orifice 68a and a pipe 66a. The storage tank 80a is connected between the separator 42a and the bottom of pipe 64a so that the amount of refrigerant stored therein will depend on the pressure drop between the separator and discharge end of the condenser, this pressure being indicated by h which will vary inversely with condenser temperature. A conduit 88 for supplying hot refrigerant vapour to the evaporator when required leads from the separator 42a to a vessel 90 which communicates via pipe 92 with a vessel 94 and via pipe 100 with the conduit 52a leading from the liquid heat-exchanger to the absorber spray 54a. The conduit 88 is normally closed by absorbtion solution at the level indicated by X but when the supply of cooling water to the condenser through line 60a is cut-off by means of a valve 104 the pressure in the separator rises and hot refrigerant vapour is forced down conduit 88, through the trap 90, into the vessel 94 and into the evaporator through pipe 96. Absorption solution from the bottom of the vessel is returned to the main flow circuit through pipes 98 and 99. The storage vessel 80a is emptied during this operation by means of a pipe 108 connected to a Venturi 106 in conduit 88. In Fig. 1 (not shown), the invention is included in a similar system operating on a cooling cycle only, and in each case the outer vessel of the liquid heat-exchanger 28a is provided with a vent line 77a to the separator. U.S.A. Specifications 2,282,503, 2,557,573, 2,563,575, 2,685,781 and 2,851,255 are referred to.

Title: Servo arrangement for adjusting the position of a transducer relative to a movable magnetic recording medium
IPC: G11B15/60
Filed: 1975-08-15
Abstract: 1509957 Automatic position control BASF AG 15 Aug 1975 [17 Aug 1974] 34019/75 Heading G3R [Also in Division G5] In a transducer position servo arrangement, a magnetic recording medium has an information signal track and an adjacent reference track formed by a single line transition between differently magnetized regions. The transducer head has at least one air-gap and is moved in an alternating manner relative to the reference track to produce a voltage signal indicating misalignment which is used for correcting the transducer position. A magnetic recording medium 1, which may be a rigid disc or a flexible coated foil disc, carries data tracks 2 and reference tracks 3 extending parallel to the data tracks and defined by line transitions between regions of differential magnetisation. These lines 3 are used for servo positioning of a magnetic data head and may be formed alongside, within, or in a layer beneath the data tracks. The data and reference tracks may be read by a flux sensitive Hall transducer or a flux variation induction sensor oscillated transversely to the tracks. The transducer may have two air gaps, or a single gap sensing both tracks and producing a composite signal which is separated into data and servo components by a filter circuit. One embodiment of the transducer, Fig. 9, has an air gap 43 for reading the data tracks 2, and a perpendicular gap 46 for reading reference tracks 3. Data signals are derived from a coil 47 associated with a magnetic circuit formed by pole pieces 40, 41, 42, airgap 43, and staggered yoke portions 44, 45. Servo positioning information is provided by a coil 48 which is wound on the yoke portion 45 only, and has a magnetic circuit comprising pole pieces 41, 42, gap 46 and yoke portions 44, 45. Both gaps may operate on the flux proportional or flux variation proportional principle. In the case of an oscillating servo track reading gap, following a path d with respect to a reference track 3, Fig. 10a, pulses are produced each time the track is crossed, Fig. 10b. The pulses are  shaped to constant duration form, Fig. 10c, and used to control the charging and discharging at constant rate of an integrating capacitor, Fig. 10d. The magnitude of the capacitor voltage at alternate transition times to, t 2 , t 4  is stored as a step voltage function, Fig. 10e, which represents the direction and magnitude of the deviation of the transducer from the track 3 and is used as a servo signal to correct the transducer position. A further embodiment of the transducer is described with reference to Figs. 6, 7 and 8 (not shown).

[Class 103 (i).] In a hydraulic transmission system the reservoir for reserve liquid is maintained under air pressure in order to keep the system full of liquid. In one modification the reservoir is divided into two compartments by a diaphragm, one compartment contains the reserve liquid and the other is provided with a tyre valve so that it may be charged with air by means of a tyre pump &c. In a further modification, the liquid is contained in a bellows 80 and a vacuum produced by the engine induction pipe is formed beneath a diaphragm 72 which causes atmospheric air pressure to act through an aperture 74 upon the diaphragm, which is thus caused to bear on the bellows 80. The degree of vacuum is limited by a check valve 84. In a further modification a bellows is used in place of the diaphragm 72.
