Title: Improvements in machines for conditioning cereal grain
IPC: F26B17/14
Filed: 1932-08-17
Abstract: 402,199. Conditioning grain. ROBINSON, W. N., and ROBINSON & SON, Ltd., T., Railway Works, Rochdale, Lancashire. Aug. 17, 1932, No. 23055. [Class 58.] A grain-conditioning column a of the type described in Specifications 238,375 and 312,852, [both in Class 58, Grain &c.], in which inverted troughs extend from an air inlet branch b at one side of the column to an air exhaustion branch c at the other side has a series of valve slides d, e, arranged in the air inlet and exhaustion conduits respectively to cover the alternate superposed rows of ports f, g, leading to the inverted troughs extending across the column. The slides at each side of the column are interconnected by bars h so that they move in unison and the slides at one side are connected to the slides at the other by ropes or bands i passing over pulleys j. A hydraulic ram k controlled by a rotary timing valve actuates the slides d, e. In operation hot air, passing in a circuit including a fan and a heater and, if desired, a dust separator, enters alternate rows of troughs from one side of the column and exhausts through the other rows of troughs on the other side ; after a period of time the valve admits fluid to the ram k which raises the valve plates at one side and lowers them at the other. The hot air then enters the column through the troughs which had previously been exhaustion troughs and escapes through the former inlet troughs. After a further short period the timing valve again operates to change over the inlet and outlet troughs.

Title: An electric striking and chiming apparatus, controlled by an electrically wound, spring-driven device
IPC: G04C21/10
Filed: 1922-08-25
Abstract: 202,516. Elam, A. G., and Sanders, M. Aug. 25, 1922. Striking-mechanism; chimes.-An electricallyoperated striking and chiming mechanism is controlled by a spring-driven train, the spring a of which is maintained in tension by an electromagnet r and lever and pawl d acting on the ratchet wheel b to which the spring is secured. The contact-arm ! l is rotated by the spindle c and springs a and closes by means of contacts in the disc p the various circuits for striking and chiming. The rotation of the spindle c is governed by the air-vane f and is started by pins i on the ratchet b raising and releasing the weighted spring j the vibrations of which free the pivoted catch h from projecting pins g on a wheel of the train. A star-wheel k re-engages the catch h and stops the movement at the appropriate times, i.e. after striking the quarters &c. A commutator disc n with two or more segments connects one or two or more of the hour-striking circuits by contact with the flexible terminals m through the first contact in the disc p as shown in Fig. 7. The commutator is rota.ted to add one more contact each hour and the circuits joined by the commutator successively operate the gong &c. z as the arm l rotates over the contacts on the plate p. A gap is left in the contact disc p between the third and fourth quarter chimes to ensure the correct timing of the. hour striking and to allow the mechanism to recover normal speed after the effort of operating the hour changing mechanism.

Title: Improvements in or relating to synthetic lubricants
IPC: C10M169/00
Filed: 1952-09-18
Abstract: The invention comprises diesters of the general formula <FORM:0718225/IV (b)/1> in which R is an alkyl or an alkoxyalkyl radical containing from 1 to 8 carbon atoms and R1 and R11 are straight or branched chain alkyl radicals containing from 3 to 9 carbon atoms. These esters are useful as lubricants.  The esters are prepared by standard esterification processes with or without a catalyst.  The diesters may be prepared from propionic acid, butyric acids, valeric acids, caproic acid, 2-ethylbutyric acid, n-heptylic acid, caprylic acid, 2-ethyl hexanoic acid, pelargonic acid, capric acid or Oxo or Fischer-Tropsch acids containing from 4 to 10 carbon atoms.  R in the formula above is preferably an alkyl radical but may also be an alkoxyalkyl radical such as butoxyethyl, butoxy ethoxy ethyl or methoxy-isopropyl.  The alkoxyglycols from which the esters are derived and having the general formula <FORM:0718225/IV (b)/2> in which R is an alkyl or alkoxyalkyl radical containing from 1 to 8 carbon atoms, may be prepared by condensing methacrolein with an alcohol or an ether alcohol in the presence of small quantities of an alkali to give a di-aldehyde which is in turn reduced to the glycol. In the examples: (a) 2-ethoxymethyl-2,4-dimethyl pentanediol-1,5 and 2-ethyl hexanoic acid are heated in the presence of xylene and p-toluene sulphonic acid as a catalyst to give 2-ethoxy-methyl-2,4 - dimethylpentanediol - 1,5 - di - 2 - ethyl-hexanoate; and (b) 2-ethoxymethyl-2,4-dimethylpentanediol-1,5 and caproic acid are heated together in the presence of toluene and sodium bisulphate as catalyst to give the dicaproic acid ester of 2-ethoxymethyl-2,4-di-methylpentanediol-1,5.ALSO:The invention comprises synthetic lubricants of general formula <FORM:0718225/III/1> in which R is an alkyl or an alkoxyalkyl radical containing from 1 to 8 carbon atoms and R1 and R11 are straight or branched chain alkyl radicals containing from 3 to 9 carbon atoms. They may be used alone or blended with other lubricants such as mineral oils or other synthetic lubricants.  Viscosity index improvers, pour point depressants, oxidation inhibitors, detergents, corrosion resisting agents and the like may be added to the esters.

Abstract: 1,137,373. Semi-conductor devices. SIEMENS A.G. 22 May, 1967 [23 May, 1966], No. 23602/67. Heading H1K. The emitter region of a transistor is formed in a diffused or epitaxial base region 3 by depositing on the surface of the base region 3, e.g. by vacuum deposition, a metal layer 4 comprising or containing the emitter dopant, protecting the required portion of the layer 4 with an etch-resistant mask, e.g. of photovarnish, etching away the remainder of the layer 4, and then alloying or diffusing the emitter dopant from the layer 4 to form the emitter region. After etching away the unwanted part of the metal layer 4, a fresh photo-resist mask 7 may be applied and a metal layer 9 may be vacuum deposited and diffused into the base region 3 simultaneously with the emitter dopant, to produce the base electrode. The surface of the base region 3 may be heated in vacuo prior to deposition of the metal layer 4. The collector region of the Si or Ge structure shown comprises an epitaxial P-type layer 2 on a P-type substrate 1 having a surface close to a (111) plane. The N-type diffused base dopant is Sb or As, while the layer 4 of emitter dopant material is of Al or a 2 : 1 Al/Au alloy. The layer 9 forming the base electrode is a mixture of Au/Sb covered with an Ag/Sb mixture. The emitter diffusion and base contact diffusion stages may be carried out separately. The techniques disclosed in co-pending Specifications 1,113,489 and 1,137,372 may be used in carrying out the present invention.

Abstract: 171,755. Lawder, E. F., Wright, A. C., and Burnip, W. May 17, 1921. Working-fluid supply; radial flow (bladed) type.- In internal combustion turbines, the combustion products are cooled by the admixture of water and additional air before passing to the turbine. The apparatus for this purpose comprises a choke tube flared at both ends, which ignites the fuel and over which cooling-air flows. At the flared end the cooling-air is discharged so as to mix with the combustion products and injected water in a mixing - chamber. Fuel issuing in a jet from a valve-controlled nozzle in a fuel supply tube mixes with combustion air supplied through parts S<2> and is fired by impinging on a heated choke tube k flared at both ends. The combustion products are cooled by injection of water through parts q<1> into a mixing-chamber i and by the admixture of additional air admitted through the passage k<2> and directed over the choke tube k by helical fins k<1> to the mixing chamber i. The cooled air is then led by passages i<1>, i<2> to a radial-flow turbine with a rotor b bladed on both sides and expands to the exhaust r. Ignition is started by a plug o with an electrically-heated disc which is inserted in the combustion chamber, the fuel tube being withdrawn a little way through a stuffing-box n, when the choke tube k is sufficiently heated, the plug o is withdrawn and the fuel tube returned.
