Title: Thermionic valve circuit
IPC: H02M1/10
Filed: 1933-02-13
Abstract: 412,337. Valve circuits. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, and KAPTEYN, P., 52, Steinstrasse, Steinst³cken, Neubabelsberg, both in Germany. Feb. 13, 1933, No. 4313. Convention date, Feb. 13, 1932. [Class 40 (v).] The operating potentials of a thermionic valve circuit are taken directly from either alternating or direct current mains without the use of a transformer, the heaters of all valves including the rectifier being connected in series. A voltage-dropping resistance 5 may be included in series with the heaters 1, 2, 3, and the cathode of the rectifier. The stage 2, which has a condenser in its input, is stated to be most effective in introducing hum, and its heater is therefore fed from the point of minimum hum. Such stages are avoided as far as possible, as by employing anode detection. Additional smoothing may be employed for the first two stages. Directly heated valves, screen grid valves, pentodes and multi-stage valves may be used. Should one heater require a lower current than the others, it may be shunted by a resistance. The first stage may have a higher amplification factor than succeeding stages.

Title: Improvements in or relating to devices for controlling temperatures in fluid heating apparatus
IPC: G05D23/185
Filed: 1934-02-10
Abstract: 433,149. Temperature regulators. BAUMANN, K., Lacey Oaks, Styal Road, Wilmslow, Cheshire, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Feb. 10, 1934, No. 4489. [Class 135] [See also Group XIII] In a fluid heater such as a steam generator or superheater, the temperature at the outlet is automatically controlled by a control member A, Fig. 2, at the outlet and by a control member C at an intermediate point in the fluid path, the effect of the member A being at least three times as great as the effect of the member C for equal changes in the temperatures at the two members. In a steam generator, .the members control the supply of heating medium or the supply of water through a byepass 3 to an intermediate point in the generator. In a superheater, the members control the supply of cooling fluid to a desuperheater in the path of the steam. Thermostats A, C, Fig. 6, control through jet regulators, the supply of pressure fluid to a piston 10 connected to a supply valve or damper 19 in the heater The escape of pressure fluid through a nozzle C<12> is controlled by a pad C<13> on a lever C<14> which is rocked upon movement of the expanding members of the regulators. The regulator A acts through bellows 20 in communication with a jet tube A<12> with a pad A<13> on a level A<14> which is rocked by the expanding member of the regulator. The position of the pivot C<15> of the lever C<14> may be further determined by the operating position of the valve 19, either by allowing the pressure below the piston 10 to act on another bellows carrying the pivot or by mechanical means. The primary control of the heater may be effected in response to the amount of fluid passing through the heater. Specifications 375,178, and 410,091, [Group XIII], are referred to.

Title: Improvements in Ploughs.
Inventor: MCLAREN JOHN
IPC: A01B3/68
Filed: 1918-03-15
Abstract: 124,059. McLaren, J., and McLaren, H. March 15, 1918. Ploughs.-To facilitate the tipping of an antibalance plough at the headlands, means are provided to cause positive movement of the axle centre of the travelling wheels equal to the movement of the centre on which the middle frame turns. In the form shown diagrammatically in Fig. 1, and in detail in Fig. 7, the plough frames A carry brackets a<6> in which the inclined slots a for the shaft b forming the bottom stretcher of the middle frame B carrying the axle c of the travelling wheels C are provided. The movement of the shaft b is controlled by toothed wheels b<6> engaging racks a<7>. The haulage ropes d<3>, d<4> are connected to one arm d<1> of a lever pivoted on the shaft b, the other arm d<2> of the lever being connected by chains, links, or the like d<5>, d<6> to the plough frames so that the plough frames take the haulage strain through the lever and the chains. Fig. 1 illustrates the position of the plough frames relative to the middle frame when the plough reaches the headland after travelling towards the right. To maintain the middle frame in the same angular relation to the plough frames until, by the haulage rope, on the reverse pull starting, acting on the stretcher b, the middle frame has been moved to the position shown in Fig. 7 in which the stretcher is at the middle point of the slots a, the upper part a<4>, a<5> of the middle frame is connected to stirrups e, e<1> passing round the stretcher b by ropes D, D<2> passing round pulleys a<2>, a<3> mounted as shown on the plough frame. These ropes cause the upper part of the frame B to move rigidly with the lower portion. In the position shown in Fig. 7, the centre of gravity of the plough frames lies to the right of the vertical plane passing through the axle c of the travelling wheels, and the raised end of the plough can readily be depressed and the plough moved horizontally to bring it into position for ploughing the next rows. Upon continuing the reverse pull of the haulage rope, the stretcher b is moved to the opposite end of the slots a with the middle frame B inclined backwardly from the stretcher and upon the links d<6> tightening the plough starts its reverse journey.

Title: Brining machines
IPC: A23B4/02
Filed: 1929-02-12
Abstract: 328,702. Fairweather, H. G. C., (Maritime Fish Corporation, Ltd.). Feb. 12, 1929. Apparatus fitted to machines for brining fish &c.-A machine for brining fish &c. comprises a frame 11 having a brining tank 12, a weighing scoop 14 pivotally attached along one edge to the frame, and a scoop 18 pivoted to the frame and adapted to fit into the tank 12 and to take the contents of the scoop 14 when it is discharged. The scoop 14 is hoisted by means operating automatically when it has been charged with a predetermined amount of fish to tip the contents into the scoop 18, which in turn is hoisted to discharge its contents by time-operated mechanism. In the construction described, the bottom of the weighing scoop 14 rests on the end 19 of a lever 20 pivotally mounted on the frame. A weight 22 slidable on lever 20 regulates the amount of fish in the scoop. The scoop 18 is attached along one edge 24 to the frame. The scoop 14 is raised by a rope 28 attached at its other end to a winding drum 26 rotatably mounted on a shaft 29 held in bearings 30 depending from the roof 31. The shaft 29 is continuously rotated through a worm wheel 37 and a worm 38 by a shaft 39. When the scoop is to be raised, the drum 26 is rotated by locking it upon the shaft 29 by a clutch comprising a toothed member 83 which rotates with shaft 29 and is displaced into or out of engagement with a toothed member 32 attached to the drum 26 by a pivoted lever 35 having a weight 36 at one end and engaging at the other end in a groove in member 33. The clutch is operated to rotate the drum 26 when the scoop 14 is filled with fish and, overcoming the resistance of the weighted lever 20, drops a few inches operating a trip rope 63 which is attached to the scoop at 64 and passes over pulleys 66 - - 70. A catch 71 on the rope 63 then engages the lever 35 to operate the raising mechanism. As the scoop rises the rope 63 is pulled until a catch 72 engages with lever 35 to disengage the clutch and allow the scoop to fall by gravity.

Title: Improvements in or relating to Telegraph Systems.
Inventor: DEARLOVE JOSEPH ARTHUR LOVEL
IPC: H04L25/20
Filed: 1917-04-02
Abstract: 114,467. Dearlove, J. A. L., Davidson, A., and Perryman, N. J. April 2, 1917 Receiving and repeating systems.-Block signals are broken up into their constituent elements by means of relays caused to vibrate automatically when signals are received. In the arrangement shown in Fig. 1, separate vibrating relays V, V<1> are used for dots and dashes, each relay being provided with differential windings 1, 2 connected respectively through a resistance R<1> and condenser K or inductance to a repeating-relay P and the middle point of a battery B, the ends of which are connected to the contacts 3, 4 of the relay tongue 5, which is connected through a resistance R<2> to the junction of the differential windings. Owing to the action of one winding being varied relatively to that of the other bv the condenser or inductance, the relays tend to vibrate automatically to indicate dots and dashes respectively, this vibration being prevented, except when dots and dashes are received, by controlling windings 7, the circuits of which are opened by a double relay D controlled by the cable relay A. If it is desired to work a perforator, it is necessary to distinguish between letter and word spacing, and for this purpose a spacing relay may be added which commences to vibrate directly the dots and dashes cease and is timed to give one impulse to the spacing key of the perforator for each centre hole of the transmitting- tape during which no signals are sent. Two arrangements for this purpose are described. Instead of providing auxiliary or controlling windings to stop the operation of the vibrating relays as required, the circuit through one or both of the operating windings of these relays may be broken. Instead of employing two separate vibrating relays for dots and dashes, a single vibrating relay may be used for causing two repeating relays to vibrate, a third relay det-ermining which of the repeating relays is connected in circuit. The Provisional Specification states that the invention may be used in quadruplex working in which it is necessary to distinguish between signals of varying amplitude and duration.

Title: A process for the manufacture of 6, 10-dimethyl-undecanone-(2)
IPC: C07C29/42
Filed: 1955-02-18
Abstract: 6 : 10 - Dimethyl - undecanone - 2 is prepared by the catalytic hydrogenation of geranylacetone or tetra-hydro pseudoionone.  A nickel or palladium catalyst may be used.  The starting materials may be prepared by reacting 6-methyl-hepten-5-one-2 or 6-methyl-heptanone-2 with an alkali metal derivative of acetylene in liquid ammonia solution, treating the product with a non-alkaline hydrolysing agent, for example, water, a dilute aqueous acid or a nonalkaline ammonium salt as such or in aqueous solution, partially hydrogenating the resulting acetylenic carbinol in the presence of a palladium or nickel catalyst which selectively catalyses reduction of a triple bond to a double bond, reacting the ethylenic carbinol so formed with diketene and decarboxylating the resulting linalyl or di-hydro-linalyl acetoacetate by heating with elimination of carbon dioxide.  The reaction with diketene is preferably effected in the presence of a weakly-acid agent such as a mixture of pyridine or choline and acetic acid; a solvent may be present.  In examples: (1) a toluene solution of 6-methyl-hepten-5-one-2 is added dropwise to a liquid ammonia solution of sodium acetylide and the product is then stripped of the ammonia and treated with aqueous sulphuric acid; the resulting dehydrolinalool is hydrogenated in petroleum ether solution using a lead-poisoned palladium calcium carbonate catalyst to form linalool which is treated in toluene solution with diketene in the presence of some pyridine and acetic acid; the resulting linalyl acetoacetate is decarboxylated at 140-165 DEG  C. to yield geranyl acetone; the latter is then hydrogenated at 95-100 DEG  C. under 500 lb. hydrogen pressure using the above mentioned palladium catalyst yielding the desired 6 : 10-dimethyl undecanone-2; (2) using the same operations, 6-methyl-heptanone-2 is converted to the desired dimethyl undecanone.  Specifications 788,302 and 788,303 are referred to.

Title: Improvements in and relating to clutches
IPC: F16D41/08
Filed: 1927-02-21
Abstract: 290,747. Farley, J. Feb. 21. 1927. Clutches, friction; facilitating changing speed. -A friction clutch comprising wedging members such as rollers cr balls adapted to be disengaged by pins which register with a control cage and specially applicable to facilitating changing speed as described in Specification 274,571 is modified in construction. Rollers A, B when free to do so will jam in either direction between flats on a polygonal boss 4 and a cylindrical friction surface 3 within a gear 2 loose on a shaft 1. The cage which supports the rollers is divided by a plane at right angles to the clutch axis into two parts 6A, 6B. The part 6A is shown in Fig. 4 divided on a diametral line for assembling. The cage part 6A supports or carries alternate rollers A while the cage part 6B, Fig. 3, supports the intervening rollers B. The parts 6A, 6B are supported on central webs 7A, 7B projecting into an annular recess 11, Fig. 2, in the boss 4. The clutch is shown in Fig. 6 engaged, the cage parts 6A, 6B being angularly displaced in opposite directions by spring 13<a>. The rollers A, B are prevented from being thrust too far by lugs C, E respectively. To disengage the clutch, the cage parts 6A, 6B are forced to and held in a middle position. For this purpose, taper register pins 10, Fig. 2, which turn with the boss 4, are thrust into holes 8A, 8B, Fig. 6, in the cage webs. The cage parts are thus brought to the position shown in Figs. 1 and 5. The pins 10 are carried by a ring 9 operated by a control fork. The rollers A, B are retained by flanges 17, Figs. 3 and 4. To engage the rollers quickly after the pins 10 have been withdrawn, the rollers may be pressed upon exteriorly by a resilient band 18, Fig. 7, disposed within the cylindrical friction member 3, the action being assisted by springs 21. This clutch is adapted to be disengaged in variable-speed gearing to free gear members to facilitate changing speed. The application is described to the variable-speed gear described in Specification 221,323, in which the clutch is for the pinion on the driving-shaft. An arrangement is described in which the improved clutch is on the countershaft of the speed gear, and is operated in unison with its engine clutch.
