Title: Improvements in adjusting means for rotary pumps
IPC: F04D15/00
Filed: 1928-09-24
Abstract: 316,052. Dehn, F. B., (Auto-Prime Pump Co.). Sept. 24, 1928. Casings; impellers having admission and discharge at periphery.-A centrifugal pump has, in an impelling chamber 2, relatively adjustable rings 8. 14 forming a pump channel 9 between them. The ring 8 and a part 10 of the ring 14 are a snug fit in the chamber 2 while the ring 14 slides in the part 10 and is adjusted by a screw 2 2engaging threads in an internal flange 11 of the part 10. In another modification, the screw 22 engaging threads in an internal flange and engages a web 25 as shown or by means of a head secured to the web by a gland so that it is only free to rotate therein. In another modification, the screw is threaded into the web 25 and has a flange to engage inside the flange 11, its outer end being fitted with a lock nut. When the screw passes through the cover it is provided with a packed gland 32. The screw 22 may have a hand wheel or notches 27, Fig. 1, for rotating and locking it. Keys 17 prevent undesired rotation of the rings. In setting up the pump, the parts are assembled with the impeller 6 free to move axially and a shim, equal to the two clearances 16 required, placed between the impeller and ring 14, the screw 22 is then rotated to press the ring firmly to the left, the cover plate 18 is then taken off and the shim removed and the parts replaced without disturbing the setting of the screw. The impeller is then rotated for a short time to allow it to assume a position half-way between the clearance surfaces and finally secured against axial movement.

Title: Dihydric phenols as modifiers for phenyl silicate
Inventor: BEANLAND ERIC
IPC: C09K5/10
Filed: 1957-08-30
Abstract: A heat transfer fluid, consisting essentially of a mixed aryl silicate in which a major proportion of the Si-bonded radicals are phenoxy radicals and a minor proportion of Si-bonded radicals are mono-oxyphenoxy radicals, may be made by heating phenyl silicate with a dihydric phenol, e.g. at 300 DEG  C for 1 to 2 hours, in an appratus in which the phenol formed by the transesterification is distilled off, any remaining free phenols being subsequently removed under vacuum.  The phenols, e.g. resorcinol, catechol and hydroquinone or any mixture thereof, are preferably used in amount of 5 to 20% by weight of the silicate.  The products are apparently equilibrium mixtures.ALSO:A heat transfer fluid is composed essentially of a mixed aryl silicate in which a major proportion of the Si-bonded radicals consists of phenoxy radicals and a minor proportion consists of mono-oxyphenoxy radicals.

Patent GB-766544-A (GB)
Title: Production of acetic acid
Inventor: ARMSTRONG GODFREY PAUL
Filed: 1953-10-07
Abstract: Acetic acid is produced by oxidizing paraffin hydrocarbons of 4-8 carbon atoms in the liquid phase at a temperature in the range 150-220 DEG  C. with molecular oxygen, continuously or intermittently withdrawing part of the reaction mixture, cooling it to a temperature below about 80 DEG  C. and separating it into an upper layer which is returned without treatment to the oxidation zone and a lower aqueous layer which is wholly or partly passed to a distillation zone, distilling said part to remove as distillate the material boiling in the presence of water up to 99 DEG  C., and returning this distillate with the fresh hydrocarbon feed to the oxidation zone, the throughput rates of the oxygen and the hydrocarbons being such that the ratio of the weight of oxygen taken up per hour to the weight of the fresh hydrocarbon fed plus the weight of distillate returned to the oxidation zone per hour is at least 0.5, and recovering acetic acid from the residues of the distillation.  Preferably also, the ratio of the weight of the distillate returned to the oxidation zone per hour to the weight of the lower aqueous layer passed to the distillation zone per hour is not greater than 0.55.  The preferred temperature range during oxidation is 160-220 DEG  C.  The other conditions used in the oxidation step are substantially those described in the parent Specification.  The acetic acid may be recovered by azeotropic drying of the wet acids followed by distillation.  Detailed examples are given of the oxidation of a straight-run gasoline fraction B.P. 10-95 DEG  C.

Oct. 5, 1932, No. 27602. [Class 27.] Articles stored in piles.-In a machine for vending articles, such as packets of ice-cream, that have to be kept cold, the bottom article 1 Fig. 1, of a pile in a magazine 2 is delivered by a reciprocating plunger 3 through a relatively long channel 4, the forward end of which is normally closed by an airtight door 11 pivoted at 12 and held closed by a spring 13. Normally the forward end of the plunger fills the channel 4 and is located immediately behind the door 11. After prepayment, a handle 5 is rotated through one revolution and by bevel gears 7, 8, crank 9, and connecting-rod 10 reciprocates the plunger which is first drawn back to allow the bottom article to fall into its path. The plunger then moves forward and pushes the article out, so that it opens the door and protrudes through a delivery opening to be grasped by the purchaser and removed. After removal of the article, the door automatically returns to its closed position. The plunger is provided with heat-insulating means 19, such as a slab of cork. In a modification, Fig. 6, the article, when pushed past the door 11, drops into a shoot 17 for removal through an orifice 18. In an alternative arrangement, the articles are arranged in circular formation on a gapped rail. Each time the plunger is actuated, the articles are pushed round so that they fall through the gap one at a time to a position in front of the plunger.

Title: Improvements in or relating to micrometer adjustment devices
IPC: G01B3/18
Filed: 1939-10-12
Abstract: 535,660. Linear-dimension gauges. KAPELLA, Ltd., REASON, R. E., and CLIFFORD, T. W. Oct. 12, 1939, Nos. 27735/39 and 14316/40. [Class 106 (ii)] . Relates to micrometer adjustment devices having a base B and carriage C adjustable thereon by means of a micrometer D mounted on one part and urged by a spring or springs into abutment with the other part, and consists in providing that the spring abuts between the carriage C and an auxiliary stop-member E adjustable relatively to a fixed abutment B<SP>2</SP> on the base so that a gauge block H can be inserted between the abutment B <SP>2</SP>and stop-member E so that if the block becomes dislodged the stopmember takes the shock and crashing of the micrometer against the abutment is avoided. The carriage C moves by wheels C<SP>1</SP> on rails C<SP>2</SP> on the base beneath a microscope carried by the base. A spring C<SP>3</SP> surrounds the tubular stopmember E and abuts between a washer E<SP>2</SP> bearing against a wall of the carriage at one end and a washer nut E<SP>3</SP> screwed on the other end and locked by a lock-nut, a flange F<SP>4</SP> on which engages over a reduced part of the micrometer spindle between its end collar D<SP>3</SP> so that a small relative movement may take place between the collar and micrometer. A thrust rod F extends between the micrometer collar D<SP>3</SP> and the abutment B<SP>2</SP> on the base. Fixed to the micrometer end of the rod F is a sleeve F<SP>1</SP> on which a collar F<SP>2</SP> screwed into the lock-nut slides. The tube E is slotted at the end at G and provided with notches G<SP>1</SP> so that the handle G<SP>2</SP> may be used to slide the tube and then turn it so that a pin B<SP>3</SP> carried by the base enters a notch to lock the tube. The spacing of the notches G<SP>1</SP> corresponds roughly to the dimensions of gauge blocks H which are placed between the abutment B<SP>2</SP> and the thrust rod F. If the block H becomes displaced the carriage and micrometer are moved only a small distance permitted by the play between F<SP>2</SP> and F<SP>1</SP>. In a modification, a tension spring is provided to tend to turn the stop E so that a notch engages the pin B<SP>3</SP>. In further modifications, the notches are widened at the entrance. In still further modifications, the abutment B<SP>2</SP> is on a slide which passes through a, lug on the base and may be locked thereto by a screw engaging one of several notches in the slide.

Oct. 6, 1931, No. 27741. Convention date, Oct. 18, 1930. [Class 55 (i).] Coal is distilled in a vertical retort which is h e a t e d internally by passage of an electric current through a resistor located in the mass of coal and through which a current is passed to coke the surrounding coal which is then used as a resistance element. The charge, which may heated externally by gas flues 12, is heated internally by an initial electrical resistor consisting of a metal tube 16 filled with coke, and extending between a n electrode 13 at the top and another 14 carried by the door 11. The coal adjacent the resistor becomes heated and coked to form a c o r e which forms a resistor and increases in diameter as the coking proceeds. In a modification, a continuously operated retort is heated in a similar way, and steam or gas is introduced at the lower end of the charge to assist the coking process.

Abstract: 960,250. Transistor circuits for radio reception; alternating current transmission systems. TELEFUNKEN A.G. Aug. 12, 1960 [Aug. 14, 1959], No. 27921/60. Headings H3T and H4R. The gain of an amplifier is automatically controlled by means of a preceding variable attenuator comprising a crystal diode D1 in series with the input to the amplifier. As shown, the amplifier 10 is a transistorized I.F. amplifier in a television receiver and signal is applied to the diode attenuator D1 over an I.F. transformer, the secondary of which comprises a centre-tapped winding L2, L3, the centre of which is earthed for I.F. and the capacity of the diode D1 is balanced out by means of a neutralizing condenser C2. The output of the amplifier 10 is rectified by a diode D2 and the D.C. control voltage across its load resistor R13 is amplified by means of a transistor D.C. amplifier T1 before application to the diode D1 over I.F. choke Dr. The standing cathode bias on diode D1 is obtained from battery B via potentiometer network R9-R12. Instead of neutralizing the capacity of diode D1, this capacity may be resonated out with a parallel inductance in series with a blocking condenser (Fig. 2, not shown). In a further modification (Fig. 5, not shown) there is interposed between the diode D2 and transistor D.C. amplifier T1 a second transistor acting as a base-controlled rectifier, its collector being fed with pulses from the line transformer.

Filed: 1932-10-07
Abstract: 399,653. Average-speed indicators. BAAGOE, A. J., 3, Rue Mathis, Paris. Oct. 7, 1932, No. 28008. [Class 106 (iii).] In an average-speed indicator in which a hand moving according to a logarithmic function of the time moves over a dial rotating according to a logarithmic function of the distance, the apparatus is zeroized by shifting a shaft axially to disconnect the elements of the apparatus and then rotating it to return the parts to their zero position. The dial driving mechanism comprises a worm shaft 30 connected to the transmission of the vehicle and meshing with a worm wheel 16, connected to a cam disc 1 engaging with a pin 5 connected to a sector 6 driving a spur wheel 7 mounted on the sleeve carrying the dial 8. The hand 9 is driven by similar mechanism operated by clockwork 15. Movement of the shaft 17 in the direction of the arrow C disengages the cam discs 1, 2 from their pins 5, 10, the shaft 30 from its worm wheel 16 and the clutch member 20 from the member 21 in the clockwork driving connection. Rotation of the shaft 17 causes its attached arms 37 to press on the heart-shaped cams 39 and zeroize the various parts. The clutch 20 may be disconnected without zeroizing whenever the vehicle is stationary, in order to obtain the average speed for the running item only.
