Title: Method of and means for signalling meter readings electrically
IPC: G01R21/00
Filed: 1927-07-14
Abstract: 274,484. Siemens & Halske Akt.- Ges. July 15, 1926, fConvention date]. Tell-tale apparatus.-The readings of a number of measuring or like instruments are electrically transmitted to a distant station by allotting alternating currents of different frequency to each instrument and by modulating or interrupting each alternating current at a rate corresponding to the reading of the particular instrument.. The alternating currents may be sent over a line or used to modulate a carrier wave which is radiated and received by wireless. In the Figure, the system is shown applied to an installation for drawing water for waterworks, the several wells B<1> - - B<3> being equipped with rotary water meters, the speed of which varies with the quantity of water passing. Each meter comprises a rotary contact wheel r making intermittent contact with a spring f. The springs j are connected through condensers to a line Ltg, whilst the contact wheels r are earthed or connected to a return line. An alternating-current generator Mg, of dynamo-electric or valve type, is connected between the line and earth and is arranged to generate voltages of various frequencies, which are applied across a coil J. When one or more of the contact devices r are closed, a tuned circuit or circuits are formed by the coil J and the particular condensers in circuit, and current of the selected frequency or frequencies passes to the amplifier V and modulates a radio transmitter S. The alternating currents supplied by the generator Mg are interruped at a frequency corresponding to the output of the particular well or wells, so that the radiated waves have a double modulation. At the receiving station the received waves are amplified and detected, and the resulting mixture of alternating currents are sorted or separated by trap circuits or by tuned relays. Each of these alternating currents is interrupted in a given rhythm by the corresponding water meter contact, and the frequency of these interruptions indicates the quantity of water passing from the corresponding well. The interruption frequency may be indicated by frequency meters in local circuits controlled by the tuned relays, or rendered visible or audible by other means. A single frequency meter may be used for all the indications, and may be switched in turn into the desired circuit.

Title: Improvements in process of producing lactic and acetic acids
IPC: C12P7/56
Filed: 1929-06-20
Abstract: 335,596. Triggs, W. W., (Wisconsin Alumni Research Foundation). June 20, 1929. Lactic and acetic acids are produced by the fermentation of pentoses and hexoses by means of a described micro-organism having an incubation temperature of 28‹ C., obtained from fermenting plant material such as silage or sauerkraut. The pentoses and hexoses are obtained from wood, sawdust, straw, corncobs or equivalent plant material by hydrolysis with dilute mineral acids, and the resultant sugar solution, which is most conveniently of from 2 to 4 per cent strength, is neutralized with milk of lime or calcium carbonate and suitable nitrogenous nutrients such as malt sprouts or other protein containing material are added. The alkaline reagent is used in excess to neutralize the lactic and acetic acids as they are formed. The inoculum is obtained by seeding a small quantity of the alkaline sugar solution with the bacteria and allowing them to grow for 24 hours before use. The micro-organism ferments either pentoses or hexoses separately or a mixture of both.

Abstract: 170,070. Du Plessis, D. J., and Verster, J. D. H. July 7, 1920. Thrashing-machines for harvesting and stripping maize cobs from the growing plants comprise a frame 1, 3, 4 supported on rollers 15, 16 and carrying one or more pairs of cob-detaching chains. The chains, which are driven from the rollers 16 through a clutch 22, chain 28, shaft 30, bevelgear 39 and sprockets 41, are arranged to diverge slightly from the front to the rear of the machine and are carried on frames 10, 11, 12, 13 pivoted on the axle 5 of the rollers and adjustable to varv their inclination to the ground, the rear end of the chains being maintained much higher than the front end. The chains pass at the front round sprockets 44 on brackets 45 which are adiustable to permit the distance between the two members of each pair of chains to be varied. Each chain consists of a number of links, each link being constructed in one piece with an outstanding finger 50, The fingers are preferably bevelled off to form a cutting-edge to cut through any cobs that might be gripped too tightly between the fingers. The fingers penetrate between the stalks and as the machine moves on pass upwards along the stems, stripping the cobs and carrying them rearwardly along a tray 53 to a container 55, the plant stems being held and crushed downwards by the rollers 16. The stems are guided to the rollers and chains by guides 51 which converge from the front of the machine, run parallel to each other for a short distance and then diverge, these guides also serving to support the fingers 50. Guards 57 which cover the sprockets 41 and 44 are provided with inner vertical edges which hold the cobs on the fingers. The driving-chain 28 may be maintained under tension by a heavy roller 58 bearing on the chain and carried by links 59.

Abstract: 1,114,217. Feeding sheets. TAGERS G.m.b.H. 2 May, 1966 [15 Jan., 1966], No. 19270/66. Heading B6B. Sheets of metal are removed from a pile by the combination of an escapement means, which bends the sheets to separate them, a magnetic field which spaces the separated sheets, and a conveyer means. A pile 2 of tinned steel sheets 1 is housed in a frame 5, and supported on two opposed sides by two shafts 6 which are rotated in synchronism in the directions E, F. Each shaft 6 has two spaced longitudinal grooves 7 therein, whereby the edges of the bottom sheet (or sheets) 1 are engaged by the grooves, the sheet is bowed transversely and separated from the pile, and falls on to two similar rotatable shafts 6a. Two or more sheets 1 may be separated together by the shafts 6 due to the weight of the pile, but single sheets are separated by the shafts 6a. The single separated sheets 1a fall into a magnetic field created by opposed magnets 3, this field having horizontal lines of force to keep the several falling sheets at a distance b from each other. As the sheets fall further to position 1c, each is engaged at opposed edges by the flights of a pair of vertical worms 9 which are constantly rotating to feed the sheets downwardly on to an endless conveyer belt device 10. The pitch of the worms 9 increases from top to bottom, whereby the sheets are more widely separated from each other. The conveyer 10 may comprise a magnetic belt, and transports the sheets to a processing apparatus.
