Abstract: 699,319. Transformers. ARC MANUFACTURING CO., Ltd. Aug. 29, 1951, No.20426/51. Class 38 (ii). A transformer having a magnetic core in two separate parts one of which is fixed and the other movable has the movable part subdivided into two parts arranged for movement in a single plane, each movable part 12 comprising a carrier 33, parallel to this plane, with stacks of ferromagnetic laminations 34 secured thereto and having guide rails 26 arranged perpendicularly to the plane of the laminations of the fixed part 11 of the core to guide the movable core parts, the carrier 33 having associated therewith spring - loaded plungers 42 which engage with the guiderails 26 so as to prevent random movement of the movable core part. Rotation of a lead-screw 31 which has right and left handed threaded portions causes the two movable parts 12 of the core to move towards, or away from, the fixed part 11 simultaneously thereby to vary the degree of coupling between the primary windings 17, 18 and the secondary windings 21, 22, the laminations 34 acting as magnetic shunts. The laminations 34 also act as magnetic shielding pieces for the carriers 33 which do not therefore become heated due to presence of the magnetic field of the transformer. Slot 55 in the carrier 33 and associated bolts 56 are provided for adjustment for wear on the lead-screw 31. A member, calibrated in amperes, is operated by a linkage from a carrier 33 and is provided to give an indication of the relative positions of the fixed and movable core parts.

Abstract: 1275208 Controlling clutches MASCHINENFABRIK AUGSBURG-NURNBERG AG 28 April 1970 [29 April 1969] 20448/70 Heading F2L An electromagnetic positive dog clutch 21 between driving and driven shafts 1, 15 from a driving unit including an electric motor 22 and a printing unit 2, and a folding unit 20, is automatically disengaged when the torque acting on the driving shaft 1, sensed by an electrodynamic torque sensor 4, exceeds a predetermined adjustable value. The motor 22 is then automatically shut-off, and driving and driven shaft brakes, or indicating devices, automatically actuated. The sensor delivers a torque signal to an amplifier and indicator 14 which feeds the signal to a mean value forming integrator 8 to eliminate the effects of short duration changes. The signal from integrator 8 is then compared with a desired value signal from an adjustable emitter 9, and if it exceeds the desired value, the error signal exceeds the threshold value of a bi-stable circuit 10 which transmits a control signal to a second bi-stable circuit 11 controlling a thyristor 12a in a power stage 12 which switches on the current to the clutch disengaging coil. The stage 12 simultaneously switches a power stage 19 to stop the motor 22 and operate the brakes or indicating devices. Depression of a push-button 13 restores circuit 11 to its initial state and the clutch re-engages. To ensure that the clutch members 3, 6 re-engage in a specific angular position, wiper contacts 17, 18 driven by the shafts 1, 15 open an electric circuit to an electromechanical position comparator 16 which sends a signal to circuit 11 to permit the clutch to reengage.

Title: Manufacture of cheese
IPC: A23C19/06
Filed: 1964-05-22
Abstract: A highly flavoured cheese which may be used in making process cheese and process cheese products is obtained by adding a starter such as lactic acid to milk, setting with rennet, cutting and cooking he resultant curd, expelling whey therefrom, salting the curd when the whey acidity reaches at least 0.40, preferably so that the mass contains 1.1-1.3% wt. salt, and curing the curd in an airtight enclosure at 65-80 DEG F. until the pH of the curd is 5.00-5.40, thereby obtaining a cheese, which has the characteristic flavour of aged cheese, in a substantially reduced curing period.  The curing is preferably effected in an oxygen-deficient atmosphere, e.g. one of nitrogen or carbon dioxide.  Prior to curing the moisture content is preferably reduced to 31-36% wt.  Suitably the curd is placed in a drum with an acid resistant coating or lining e.g. of plastic, fitted with a lid having an annular array of 1/4 inch holes round the edge through which the moisture may drain.  Afterwards, the lid is replaced by an airtight lid, desirably after replacing the atmosphere by an atmosphere which will not sustain mold growth, and the curd is allowed to cure, normally for 5-7 weeks.
