Abstract: 880,612. Vehicle power steering. ZAHNRADFABRIK FRIEDRICHSHAFEN A.G. Jan. 28, 1959 [Feb. 1, 1958], No. 3134/59. Addition to 819,559. Class 79(5). In a power assisted steering system for motor -vehicles according to the parent Specification in which a double acting power piston 2, Fig. 1, is controlled from an internal combined steering nut and control slide 3 actuated from a steering spindle 4 at one end of the piston 2, axial adjustment between the slide 3 and piston 2 is provided by an adjusting nut 41 so that in the neutral position of steering the pressures obtained on the unegual areas at opposite ends of the piston 2 are arranged to balance the forces on the piston. The adjusting nut 41 is yieldingly held in the centralised position by a reaction ring 47 and spring housing 48 engaged against stops 58, 59 on the piston 2 and nut 41 by interchangeable springs 49 and by supply pressure connected to the spring chamber through a passage 45. The springs 49 and supply pressure provide the required degree of steering feel and limited play between the reaction ring 47 and spring housing 48 provides for manual steering. The adjusting nut 41 is threaded at 42 on the steering nut 3 and is adjustable thereon by turning at grooves 63. After adjustment the nuts are relatively locked by caulking a narrow ring 44 into bores 30 of the steering nut.

Abstract: 1,202,622. Anti-vibration mountings; mounting bearings. WESTINGHOUSE ELECTRIC CORP. 22 Jan., 1968 [24 Feb., 1967], No. 3191/68. Headings F2A and F2S. [Also in Division H2] A resilient mounting ring for supporting a rotating machine on a base comprises an outer sleeve 16, Fig. 2, secured to the base and an inner sleeve 14 containing a hub 5, Fig. 1, which carries a bearing for the machine shaft, the sleeves being joined by a plurality of resilient corrugated members 22 which are each secured at their extremities to the inner sleeve and at an intermediate point to the outer sleeve. The intermediate points are secured to protuberances 28 on the outer sleeve and the extremities to blocks 25, 26 formed integrally with the inner sleeve, and protuberances 35 on the blocks 25 co-operate with protuberances 34 on the outer sleeve to limit the relative circumferential movement of the sleeves and hence limit the stress in the corrugated members. Raised portions 17, Fig. 3 (not shown), formed on the outer surface of the outer sleeve provide a groove (18) which contains a strap 9 by means of which the outer sleeve is fixed to a pedestal 8. A slot 19 and hinge 20 permit slight changes in the diameter of the outer sleeve as the strap 9 is tightened. The sleeves 14, 16 and corrugated members 22 may be made of plastics or elastomeric material.

[Also in Division G3] An indicator or calendar, for forward planning of e.g. cattle breeding operations, comprises a member 1 bearing a time-scale 20, a set of pointers 21 having fixed spaced relations to each other and movable in a body over the scale, and at least one multi-sided element 30 bearing an indication on each face corresponding to a separate step in the enterprise, and being adapted to be temporarily secured (e.g. by magnetic attraction) to the face of member 1. As described, scale 20 is circular and the elements 30 are cubes; each of the faces 41-46 of all the cubes is coloured to represent different stages in the breeding cycle, e.g. serving, calving whereas each cube has a different number 31 on all its faces representative of a particular cow. The pointers 10-15 are secured to a disc 7, stepwise rotation of which is ensured by a ratchet-and-pawl mechanism (6), (17), Fig. 3 (not shown). Pointer 10 is moved by hand day-by-day. As successive stages of a cow's cycle actually occur, the corresponding face of her cube 30 is turned up. Thus the markings on disc 7 between a pair of pointers indicate what step ought to be taken, e.g. service, and the time available; the cubes indicate whether that step actually has been taken. Other contemplated applications include manufacturing, building and debt collecting.

Optimum output is produced when the total positive charges of strontium, lithium and the activator elements equal the total positive charges of germanium i.e. when 2u + 1w + 3z ­ 4y, when for the above preferred composition u = 1.29; w = 1; z = 0.108 and y = 1. 254 n.m.U.V excitation produces line emission output of 550 nm. and 620 nm. for Tb and Eu activated phosphors respectively and similar green and red emissions by electron excitation allowing use in fluorescent lamps and colour TV.  In a method of preparation, the raw mix is fired at a temperature from 900 DEG  C. to 1250 DEG  C. preferably 1150 DEG C., 1000 DEG  C. and 950 DEG  C. for lithium concentrations of 0.2, 0.6, and 1.0 respectively, for from 1 to 3 hours, preferably 2 hours.

The light source may be stepped up in intensity by insertion of the note to increase the blue content. The outputs of bridge connected photocells PC1-6 are connected to the input of a temperature compensated long-tailed-pair TR1 TR The sensitivity of which is greater for an excess photo-cell output than for a deficiency to apply a "0" or a "1" output over line 44 to digital circuitry controlling motor driven rollers for feeding forward the note. The individual photocell bridges are calibrated by inserting a genuine note and balancing resistors VR1-6. The arrangement may be arranged to shut down for lack of change in a change machine or in the case of store overfill. Additional photo-cells are provided to monitor the presence of the note at various stages to prevent fraudulent operation, and shutters operated by the leading edge of the note for such purposes may be included. Digital operating circuitry is described with reference to Figs. 4 and 5 (not shwon).

Abstract: 764,374. Making transformers. GENERAL ELECTRIC CO. Feb. 9, 1955 [Feb. 10, 1954], No. 3896/65. Class 83 (2). [Also in Group XXXV] A wound transformer core is made by winding magnetic strip into a loop, preferably unwinding the turns and forming them into a polygon of fewer turns such as is shown in Fig. 2, cutting the polygon at a number of places, e.g. 5, 6, to form groups of turns, e.g. 11, 12 of different mean lengths and successively superimposing strips from each group alternately to form a core. The cuts may slope relative to a plane at right angles to the general direction of the laminations at the cut, being made by cutting the turns at right-angles after gripping them tightly to one side of the cut, Fig. 3 (not shown). Thus when the original ring is rectangular, the two groups form near rectangles, Figs. 4, 5, the strip lengths being respectively shorter and longer than required for an exact rectangle, and such that the group ends 28, 14 slope in different directions. When assembled the end of one strip butts against the beginning of the next, and the joints 19, 20, 22 are staggered. The original ring may be annealed in an inert gas before cutting, and the core finally assembled around one or more coils, Fig. 7 (not shown). The polygon of Fig. 2 may be made with a number of sides other than eight, and more cuts than two made, it then being possible to assemble the core around the coils with less bending of the strips.

Apparatus for recording and playing back a sound track in the form of a closed spiral path 20 on a magnetic sheet 64, comprises a casing, 1, pressure means 59 for holding the magnetic sheet on the casing, and a turntable 2 carrying a transducer 9 which is moved radially during rotation of the turntable by means of a stationary guide plate 11 having an endless spiral groove 12 therein. The turntable is driven by batteries 17 and motor 15 in driving engagement with a stationary ring 13. An abutment 25 on the edge of the turntable 2 rotates a counter indicator 24 step by step each revolution, readings of the indicator being visible through a transparent dial 26. When the transducer returns to the outer convolution of the spiral, circuit is broken by the engagement of a button switch 18 with a member 21. Starting is reestablished by manual pressure on a button 22 which temporarily disengages the member 21 from the button switch 18. The pressure means comprises a transparent plate 57, an opaque hard plate 58 and a resilient plate 59 hinged at 60 to a sprung member 62 so that a stack of blank sheets may be pressed against the turntable and the lowest readily removed when recorded. Where it is necessary to view the upper face of a record when tranducing, the plates 58, 59 may be hinged out of the way and pressure applied by the plate 57, although this pressure will be less uniform than when using the resilient plate 59. The record, described in the divided Specification 930,978, may carry two independent overlapped tracks (Fig 7, not shown) and the coating particles may be circularly oriented (see Specification 930,978 as abridged in Group XXXV).
