Abstract: 1293135 Engine mountings; balancing ROVER CO Ltd 19 Dec 1969 [7 Dec 1968] 58256/68 Heading F1M The invetion relates to a multi-cylinder inline internal combustion piston engine 10 having an odd number of cylinders and in which the number and spacial distribution of the cylinders and coacting pistons together with any balance weights which are rotatable in fixed relationship to a crank-shaft of the engine is such that there is applied to the engine a pure couple or torque whose magnitude in a plane including the crankshaft axis and the axes of the cylinders varies cyclically in time. The engine includes a resilient means 44 disposed on at least one side of the engine and arranged to support the engine from a supporting structure therefor, the resilient means being positioned substantially on or adjacent an axis through the centre of gravity of the engine normal to the plane including the crank-shaft axis. The resilient means is torsionally flexible about the axis through the centre of gravity and has a greater stiffness in one direction normal to the axis than in another direction normal to the axis whereby to provide adequate attenuation of the rotational oscillation of the engine about the axis which is transmitted to the supporting structure. A separate resilient means may be arranged on each side of the engine. A modified resilient means comprising a sleeve of rubber like material within a metal sleeve is described.

Title: Video signal reproducing apparatus
IPC: H04N5/95
Filed: 1971-12-17
Abstract: 1376449 Automatic tension control SONY CORP 17 Dec 1971 [19 Dec 1970] 58683/71 Heading G3R  In video recording apparatus having video signals recorded on magnetic tape using oblique tracks, the tape tension is controlled according to a measured time interval between the passage of the end of one track and the start of a subsequent track. As shown, the signals are scanned by magnetic heads 2, 3 on a rotary assembly 1, and pass through a mixer 16 and demodulator 17 to terminal 19 via output circuit 18, and to separators 20, 21. From separator 21, horizontal synchronizing pulses are counted by counter 22, which gives an output pulse after a predetermined number, and which is reset at the start of a subsequent track by a vertical synchronizing pulse from separator 20. The output of counter 22 triggers monostable multivibrator 23, whose output is integrated and passes to gate 25, which is opened by vertical synchronizing pulses via monostable multivibrator 26, to give an output proportional to the period between adjacent tracks. Alternate pulses of this output are fed via gate 27 and associated trigger 28 to controller 29 to control the tape tension either using the supply reel motor 30 or the drive to the capstan 8. In an alternative Fig. 3 (not shown) the multivibrator is bi-stable, trigger 28 omitted and gate 25 is only opened by alternate vertical synchronizing signals. A known control system, to synchronize the position and speed of the magnetic heads relative to the oblique tracks on the tape, compares a tape speed signal, measured by a fixed magnetic head from signals recorded on the tape, and a signal indicative of the speed and phase of the rotary magnetic heads, as measured by detector 11, to control the rotary head assembly drive motor 4.

Title: Process for selectively removing adipose tissue from the human body.
IPC: A61K8/41
Filed: 1978-08-24
Abstract: A process of selective slimming comprises local vasodilation by application of a suitable preparation to the parts of the body where weight loss or size reduction is most required, at a time when the condition of the blood is such that it is taking up components stored in the adipose tissues. Such a condition may be brought about within one half to two hours after a low carbohydrate high protein meal. Vaso constrictors may be applied to parts of the body where weight or size loss is particularly not required at the same time as a vasodilator preparation is applied to the areas where weight loss is required.

Patent GB-2029171-A (GB)
Title: Reading magnetic records
IPC: G11B20/14
Filed: 1979-07-09
Abstract: The boundaries of each bit and the clock information are denoted on a magnetic record by regular boundary transition of, e.g. N-N polarity. The binary values are denoted by the phase positions of interior transitions int, e.g. S-S, relative to the boundaries. The interior transitions have phases of for example 120 DEG  or 240 DEG  relative to the boundary transitions. To decode the record, a counter measures the time interval between the boundary transitions Bnd of a bit. A further counter measures the time interval between the interior transition of the bit and one of its boundary transitions. A comparator compares a count corresponding to 180 DEG  of phase with the count corresponding to 120 DEG  or 240 DEG  of phase to determine whether the interior transition has a phase of more or less than 180 DEG  and thus the binary value of that bit. <IMAGE>

Title: Method of and apparatus for testing laminated magnetic cores
IPC: G01R31/02
Filed: 1979-08-31
Abstract: A laminated magnetic core, e.g. the stator core 10 of an electric rotating machine, is tested for hot spots by inducing in the core an alternating flux parallel to the laminations. Flux in a certain direction and at a selected location on the surface of the core is then detected and the component in phase quadrature with the mean leakage flux is indicated to identify the presence of a hot spot. Apparatus for performing the method has an excitation winding for inducing the alternating flux, a reference coil for detecting the mean leakage flux and a pair of pick up coils which are connected together in series opposition to sense the spacial gradient of the detected flux. The pick up coils are traversed along successive pairs of the teeth 12 on the inside surface of the core to locate hot spots. The voltage developed across the pick up coils is amplified and fed to the signal input of a phase sensitive detector to the reference input of which is applied the integrated voltage developed across the reference coil. <IMAGE>

Title: Improvements in or Relating to Positive Displacement Pump Systems
IPC: F04C14/26
Filed: 1979-12-04
Abstract: A positive displacement pump system has first and second delivery passages 11, 12 for the pumped fluid and a main discharge passage 15. A control valve 20 operating in dependence on the pressure drop across an orifice 17 in the discharge passage diverts through overspill porting 14 a proportion of the flow through the second delivery passage 12, the remainder added to the flow from the first delivery passage 11 and passed to the discharge passage. The control valve also regulates the by- passing of a proportion of the flow from the first delivery passage to the overspill porting. For a given movement of the valve member, the increase of effective area of communication between the second delivery passage and the overspill porting is greater than that between the first delivery passage and the overspill porting. <IMAGE>
