Abstract: 642,753. Mounting electric motors. GENERAL ELECTRIC CO., Ltd., LEDGER, R., and PLATT, A. D. B. Oct. 31, 1947, No. 29117. [Class 79 (iii)] [Also in Group XXXIV] In a suspension arrangement for a geared electric traction motor 3, the motor being axle-hung and having a pinion 7 meshing with a gear wheel 8 on the axle 5 (shown in plan Fig. 1 applied to a rail vehicle), the bearings 1, 2 of the motor on the axle are made resilient by the interposition of a resilient bush between the axle and bearing housing, and means are provided for limiting relative movement between the motor and axle in the plane containing the axes of the pinion 7 and gear wheel 8. Each bearing comprises a cylindrical rubber bush 10 bonded to an inner bronze sleeve 11 having a white metal bearing surface 13 and an outer steel sleeve 12 which is clamped in the motor bearing housing. The relative movement between the motor and the axle in the plane containing the axes of the pinion and gear wheel is limited by two diametrically opposite projections 14 on the sleeve 11 which pass through the rubber 10 and lie close to the inside surface of the steel shell 12. For lubrication of the bearings 1, 2, each resilient bush 10, 11, 12 is slotted in the vicinity of wool packing 16 which is fed with oil from an oil chamber 15, Fig. 2.

Title: Improvements relating to the conditioning of wheat
IPC: B02B1/08
Filed: 1945-11-05
Abstract: Wheat with a suitable moisture content is conditioned by heating in a high frequency electric field and subsequently cooling, e.g. in cold water.  The desired moisture content is generally obtained by first treating the wheat by damping or drying and allowing it to lie for the moisture content to become uniform and then spraying to ensure higher moisture content in and immediately below the bran. Alternatively steam may be injected into a mass of wheat pre-dried if necessary.

Title: Improvements in or relating to sound recording and reproducing apparatus
IPC: G11B5/02
Filed: 1948-11-11
Abstract: 652,340. Recording and reproducing sound. FERRANTI, Ltd., and WILLIAMSON, D. T. N. Nov. 11, 1948, No. 29333. [Class 40 (ii)] A method of magnetically or optically recording and reproducing sound comprises separating the electrical sound signals by filter networks into two or more frequency bands not wider than the effective range of the recording medium, heterodyning the signal bands outside the said effective range to convert said bands into said effective range, and separately recording all said frequency bands on to the recording medium. In the embodiment described in which the effective range is considered to be 0-5,000 cycles, the sound may be separated into bands of 0-5,000 cycles, 5,000-10,000 cycles and 10,000-15,000 cycles. .The 0-5,000 cycle band is recorded direct, while the 5,000-10,000 and 10,000-15,000 cycle bands are heterodyned with oscillator frequencies of 10,000 and 15,000 cycles respectively so that the difference-frequencies resulting therefrom would produce signals with reduced and inverted frequencies within the range 5,000-0 cycles. To reproduce the sound, the primary band of 0-5,000 cycles is reproduced normally, but the other bands are subjected to reverse heterodyning steps by their being heterodyned with the appropriate oscillator frequencies and the original frequencies extracted and reproduced with the sound from the 0-5,000 cycle band. The frequency of the oscillator used in reproduction may be accurately adjusted to the frequency of the oscillator used during recording by means of frequency stabilizing means such as a tuning fork or crystal. Preferably, however, a synchronizing signal from the recording oscillator may be recorded on the medium and utilized to control the frequency of the reproducing oscillator. The reproducing oscillator may be dispensed with by using the synchronizing signals for heterodyning.

Blades 6 are held between ledges 8 and eccentric clamping-studs 10 within a chuck 4 in such a manner that the surfaces to be ground are slightly within a constant circle 7. The grinder 15, adapted to be lowered into the chuck by rack-and-pinion gearing 20, 21, is adjusted transversely by screws 28 so that at the operative part of its periphery it coincides with the circle 7, the chuck being given a relatively slow rotation by gearing 14, 13 and the grinder being driven relatively fast. In order to grind the other faces of the blades the razors are disconnected and then reinserted into the chuck from the opposite end, the chuck being reversely seated in the support 12. By using a constant circle of different radius the concavity of the blades is correspondingly varied.
