Title: Improvements in the Lubrication of Milk Centrifugal and the like.
IPC: F16N7/18
Filed: 1917-11-09
Abstract: 111,662. Holte, H., and Aktieselskapet Separator. Nov. 28, 1916, [Convention date]. Lubricant conveyed by mechanical means.-To lubricate the upper spindle bearing of a milk centrifugad machine &c., oil raised from a base 14 by a slowly moving gear wheel 6 is removed by a scraper 7 and delivered to a trough 9, which communicates with a helical groove 11 in the bearing. The oil ascends the groove reaching an upper chamber 12 and returns by openings 13 to the trough 9, the overflow from which lubricates the gearing driving the spindle.

Title: Improvements in or relating to light metal pistons for internal combustion engines and compressors
IPC: F02F3/04
Filed: 1960-05-11
Abstract: 948,342. Pistons. KARL SCHMIDT G.m.b.H. May 11, 1960 [May 13, 1959], No. 16666/60. Heading F2T. A light-metal piston comprises reinforcing ribs d<SP>1</SP>, Figs. 1 and 2, extending upwardly and outwardly with respect to the axis of the piston from the gudgeon pin bosses c to the piston head a, expansion-control members e<SP>1</SP> cast or pressed into the piston skirt b adjacent the bosses and gaps n of greater cross-sectional depth than width separating the controlled skirt portion from the piston head and ribs in a peripheral zone extending from points g adjacent one boss to similar points adjacent the opposite boss. As shown the head a is separated from the skirt b by horizontal slots f<SP>1</SP> which extend between the points g and are at least as wide as they are deep, and the control members e<SP>1</SP> extend upwardly as far as the lowermost piston groove. Depending upon the angularity of each rib d<SP>1</SP>, it will obscure a greater or less extent of a slot f<SP>1</SP> and, over the arc so obscured the control member e<SP>1</SP> is separated from it by the gap n; separation between the piston head and skirt portion is therefore provided either by a combination of the slots f<SP>1</SP> and gaps n, or, if the ribs should completely obscure the slots, by gaps n only. The control member e shown in Fig. 4 has its peripheral portion extended outwardly from the bosses in a region k which extends as far as the lowermost piston groove and is arranged to provide the desired separation in the form of the slots f<SP>1</SP> and gaps n. In the arrangement shown in Fig. 3 there is provided an additional control member or band h which may be of wire mesh, have a lower coefficient of expansion than that of the material of the piston and be connected to the control member e<SP>1</SP>. This additional band need not extend so far downwardly so far as shown in the piston skirt but may be of rectangular or trapezoidal crosssection and disposed either inside or outside the control member.

Title: Improvements in or relating to electronic amplifiers
IPC: H03G11/00
Filed: 1945-06-30
Abstract: 601,171. Valve amplifying and limiting circuits. PARKER, E., and BUCKINGHAM, J. June 30, 1945, No. 16700. [Classes 40 (v) and 40 (vi)] In a video amplifier and limiter, the signal is fed to the grid of valve V1 coupled to valve V2 only by the cathode resistor R1, the output signal appearing across the anode load R2. The gain may be varied by altering the setting of potentiometer R1 which controls the degree of negative feed-back. The output is linearly related to the input until the grid of valve V2 is driven beyond cut-off, the output then remaining constant with increase in input signal.

Abstract: 697,265. Photo-electrically controlled tube closing machines. INDUSTRIE - WERKE KARLSRUHE AKT.-GES. July 18, 1951 [July 26, 1950], No. 16989/51. Class 40 (iii). Marks on the ends of tubes, e.g. toothpaste containers to be closed are detected photoelectrically so that the tubes are rotated to the correct position for closing. As shown, a lever 3 and stops 23 allow tubes 1 to fall one at a time into a conveyer 20 mounted on a turntable 6. A fixed stop 4 ensures that they enter the funnel 20 head end foremost. The tubes are then carried to a position beneath a head 7 which forces a die into them to ensure roundness. The tube then passes to a photoelectric scanning head 8 which contains two photo-electric cells and a light source. The edge of the tube carrier which is toothed engages a driven pinion 12 and is thereby rotated until the photo-cell detects the marks when the cells energize a solenoid 17 to withdrawn the pinion from engagement with the carrier. The tube is then in the correct angular position for closing.

Title: Improvement in Carbureters.
Inventor: MACKENZIE JOHN WILLIAM
IPC: F02M1/00
Filed: 1916-11-29
Abstract: 111,525. Mackenzie, J. W. (King Petroleum Power Co). Nov. 29, 1916. Spray carburettors.-In a carburettor employing two or more fuels, the air supply is controlled automatically by suction of the engine, and the mixture throttle is interconnected with the valve by which the selected fuel is admitted. The main air inlet is fitted with a pivoted disk valve 7 which stands vertically at full suction and tends to be closed by a weight 8. An inclined vane 14 on the side of the valve which ascends in opening, has a central slot to prevent the formation of a pocket of low pressure or an eddy in the air current. The valve 7 can be manually operated by a lever. A vertically moving disk 72 in the air current above the valve 7 controls, by means of link-work 75, 81, an auxiliary air valve in a passage 70 and also a choke valve 78 placed immediately above the mixture throttle 16. The air passes through a Venturi tube 2, to which fuel is supplied through nozzles 19<1>, 33 Fig. 5. At high suctions, a ring valve 5, sliding on the outside of the tube 2, rises to allow some of the air to pass abound the tube. The fuels are supplied to two similar float chambers through passages 28, Fig. 7. controlled by valves 29. The outlet from each chamber is through an annular space 32 surrounding the pipe 28. A rotary valve 24 connects either float chamber to the nozzles 19<1>, 33 through passages 23, 34, there being an intermediate position in which both passages are closed. The valve 24 and the throttle 16 are operated simultaneously by a single lever 58, Fig. 12, pivoted on an arm 57 projecting from a slotted sleeve 50, 52. Fig. 2, which actuates the throttle 16, the lever 58 having a pin 61 engaging an arm 62 to actuate the valve. The movement of the arms 57, 62 is limited by stops 63, 65, and the arms can be manipulated so as to. supply either fuel with the throttle open or closed or at any intermediate position.

The tapping roller is provided with insulated current collecting segments 3a, 3b, around its circumference. The turns of said winding are pitched to conform with the pitch of the segments, the evennumbered and odd-numbered segments respectively each being connected in a group and the two groups being interconnected by a current-limiting reactor 5 having a centre tap. The winding consists of flat, insulated wire wound edgewise 10 into a helical slot pitched to conform with the pitch of the segments. The turns may be held in rack-like or rake-like supporting bars extending in the direction of the winding axis. The tapping roller comprises two similar axially interfitting, cup-shaped halves (11) (Fig. 4, not shown) having deeply slotted sides in such a manner that the teeth (3a) between the slots (3b<SP>1</SP>) of one half engage the slots of the other half with the interposition of an insulation and form the current collecting segments. The transfer of current is effected by a multi-contact bush on the tapping roller to a pivot or half shaft received into said bush. Each segment is provided with a V-section trough 9. The tapping roller is loaded by at least one spring (17), (Fig. 3, not shown), which urges the roller against the turns. Current tapping equipment of this type may be used for a polyphase transformer or a polyphase reactance coil, in which a plurality of tapping rollers (2), (Fig. 7, not shown), are mounted in a common carrier on a slide which is movable parallel to the axes of the co-operating windings.
