Title: Improvements in feedstuffs for young mammals
Inventor: PORTER JOSEPH WILLIAM GEOFFREY
IPC: A23K1/165
Filed: 1957-05-01
Abstract: A feedstuff for young mammals capable of utilising starch degradation products only as glucose comprises raw or dextrinised vegetable starch and a minor proportion of an added enzyme system which can degrade the vegetable starch to glucose in the gut of the mammals. The enzyme system preferably constitutes less than 1% of the dry weight of a balanced protein and fat containing feedstuff and is employed in sufficient concentration to degrade the whole of the vegetable starch to glucose in the gut of the mammals within 1 1/2 hours.  There may be employed a crude enzyme concentrate from broth in which Aspergillus niger has been cultured or an amylase enzyme capable of degrading starch to maltose and a maltase enzyme capable of degrading maltose to glucose.  Vegetable starches include wheat or maize starch, oat or wheat flour, rolled oats and flaked maize. According to an example, one day's diet for a young 100 lb. calf comprised one gallon of an aqueous dispersion of 5 lb. liquid white milk, 0,5 lb. skim milk powder, 0,45 lb. maize starch and 40 gm. of a crude extract prepared from Aspergillus niger fermentation broth.

Abstract: 1498674 Variable resistors HITACHI Ltd 9 April 1975 [10 April 1974] 14616/75 Heading H1S In a variable resistor comprising an insulating base 21, e.g. of ceramic, carrying cermet tracks 25, 29 which are respectively resistive and conductive and are engaged by corresponding wiper portions of a slider 51, at least one end of the resistive track 25 being connected to a further conductive cermet layer such as a strip 22 or 24, cermet resistance layers are formed over the conductive material wherever it is wiped by the slider to prevent the adhesion of solder. As described conductive cermet material, e.g. of silver-palladium is printed on the base to form strips 22-24 and the inner wiper track 29. The resistive material containing ruthenium or silver-palladium compounds is then printed on so as to form the track 25, which overlies the ends of strips 22 and 24, and an area 28 over the inner wiper track. The base is then fired, and may also have been fired between the two printing operations, and the overlaid areas acquire glassy surfaces to which solder will not adhere when tags 57-59 are flow soldered to the strips 22-24. Wiper 51 is fixed to a disc 48, the rotation of which is limited by a lug 49 engaging an ear 45 on metal case 41. Wiper arms 52 engage the resistive track 25 and arms 53 engage layer 28 over the track 29, the extra resistance due to the overlying material being negligible.

Tapping.-A multiple-spindle nut-tapping machine, designed to stop working after tapping a predetermined number of blanks, has the tapspindles lifted by fluid pressure and fed by gravity. The tap-spindle B of each unit is driven by ordinary toothed gearing and moves axially with the rod H<1> of a piston operating in the cylinder G. A slide-valve for admission and exhaust of working-fluid is mounted in a chest I and is controlled either manually by actuation of the lever 20, or automatically by a bar 26, Fig. 2, mounted on the piston-rod. A mutilated toothed wheel J carried by the bar 26, has as many teeth as there are blanks to be tapped in each period of working, and is adapted to lift the valve for exhaust b one of its teeth engaging a pin 36 on the valve spindle. The wheel is rotated one tooth at the end of each downward stroke of the tap, by a fixed spring-pressed pawl 34, and is retained from retrograde movement by a second pawl 38. The valve is moved to cut off exhaust and open to admission by the bar 26 engaging a nut 25 on a valve-operating spindle 24. Operation proceeds in this sequence till failure of the valve to open to exhaust occurs owing to the pressure of a space on the wheel J. The blank-feeding mechanism forming the subject-matter of Specification 183,785 is shown on the drawings.
