Filed: 1959-01-30
Abstract: In the drum malting of barley, the barley is placed in a drum or cylinder A having its circumferential wall 8 reticulated to expose the barley to the ambient air, the drum or cylinder is rotated to cause the barley to form an inclined top surface short of the axis 10 and down which the upper grains fall to cause a successive shifting of the barley which brings all parts to the surface at some time and exposes them to aeration and dissipation of heat by the ambient air passing naturally through the drum, and the barley in the lower part is caused periodically to pass through water or liquor in a steeping unit B so that the barley is alternately wetted and aerated. The steep tank is mounted on a wheeled frame 23 and is supported <PICT:0954973/C3/1> by screw jacks 22 (or hydraulic rams) to be raised into its operative position beneath the drum; water or steep liquor may also be sprayed over the barley from a perforated hollow axle of the drum.

Abstract: 651,457. Voice frequency signalling. STANDARD TELEPHONES & CABLES, Ltd. Feb. 7, 1947, No. 3712. [Class 40 (iv)] In a system incorporating a signal receiver SC, GC in the incoming pair of a four-wire circuit and subject to unwanted signals from the near end 2-4 wire termination (i.e. coming in over the OUTPUT terminals), the effect of these unwanted signals is minimized by the use of a high impedance valve V1 fed by the wanted incoming signals and whose output is fed jointly to the signal receiver and to the incoming side of the 2-4 wire termination which comprise conjugate arms of a hybrid transformer T2. The Specification shows mathematically how the use of the high impedance valve V1 inserts a large loss between the OUTPUT terminals and the signal receiver and this effect is further enhanced by the use of the hybrid transformer T2. Specification 501,028 is referred to.
