Abstract: 459,401. Separating solid materials. BARKER, W. H., Etna Works, Fenton, Stoke-on-Trent. Nov. 11, 1935, No. 31121. [Class 117] In apparatus for separating-materials of different density, such as mixtures of coal and refuse, of the type in which the materials are stratified on a jigging table which may be pervious to a rising current of air, the settled materials are discharged laterally by shoots which are hinged to the deck at one end and at the other are hinged to a fixed support which may be adjustable. As shown in the drawings, the separating deck a is of air pervious material and is mounted in a box b to which air is supplied. The deck is slightly inclined from the feed to the discharge end and is jigged vertically by bell-crank levers and an eccentric rod. Near the discharge end, a bottom discharge slot c is provided and leads to a laterally inclined or ridged plate i. At one or both sides a shoot k is provided. This shoot is hinged to the deck at l and to standards m so as to partake of the igging movements of the deck. Preferably the standards m are adjustable as, by the turn-buckle device o, so as to regulate the rate of discharge.

Filed: 1976-07-27
Abstract: 1506689 Tip-up seats LORD CORP 27 July 1976 [6 Aug 1975] 31200/76 Heading A4B [Also in Division E2]  A hinge for securing a seat portion 22 of a seat structure to a side support 16 comprises two brackets 26, 28 at least partially spaced apart, and a member 54 of visco-elastic material disposed between and secured to the brackets 26, 28 to permit relative rotation of the brackets about a first axis 70 passing through the member 54, at least one of the brackets e.g. 26 including a stop device e.g. lug 36 engageable with the other bracket e.g. at a lug 44 to prevent relative rotation about the axis 70 in one direction beyond a predetermined relative orientation of the brackets (as in Fig. 4, which shows the seat in an "unoccupied" position) but then permitting relative rotation of the brackets about a second axis 72 spaced from the axis 70 and passing through a point of contact between the stop device 36 and other bracket 44. Such rotation occurs when the seat is pushed back from an "unoccupied" position, Fig. 4, to an "upright" position, Fig. 6. As shown, when the seat becomes "occupied" it moves to the position of Fig. 5 where engagement of lugs 38, 40 on bracket 26 with lugs 42, 44 on bracket 28 prevent further rotation. The member 54 is stressed in torsion during relative rotation between the Fig. 4 and 5 positions about the axis 70 and remains so at the position of Fig. 4, but further stress in moving to the Fig. 6 position is essentially in shear. A block of resilient material 50 is provided in the lug 44 to cushion engagement with lugs 36 or 40.

Title: Improvements in or relating to process and apparatus for recovery of ammonia from an ammonia-containing gas
IPC: C01C1/242
Filed: 1953-11-16
Abstract: <PICT:0735167/III/1> <PICT:0735167/III/2> In a primary saturator 10 a dilute sulphuric acid solution saturated with ammonium sulphate is sprayed into coke oven gas and the supersaturated solution passes through a main circuit line 22 to a crystallizer 24.  Following the deposit of crystals therein the desupersaturated solution is returned by a pump 28 to the saturator spray 20 through a high-pressure line 32.  Make-up acid is added in a tar skimmer 36 receiving a minor quantity of liquor from the saturator, this stream passing to another liquor storage tank 42, which also receives liquor drawn from the crystallizer by a pump 58 after removal of crystals in a separator 66; liquor from the tank is pumped to spray 50 in a secondary saturator 16.  A by-pass 72 from line 32 discharges through a reducing valve 74 into the low-pressure side of the main circuit, the upward flow in the crystallizer being varied by adjusting the valve setting.  In a modified plant, Fig. 3, in which the crystallizer is disposed to the high-pressure side of the main circuit the saturator 210 comprises a jacket around the crystallizer 206 from the upper part of which spray nozzles 274 project so as to direct the spray against the gas flow.  Solution withdrawn from the saturator through a pipe 260 is returned to the crystallizer by a pump 262 through a valved pipe 264.  An outlet pipe 278 at the top leads past pressure-reducing means to a dissolver 280 receiving steam through a perforated inlet 294 and make-up acid through a pipe 298.  Solution is returned to the saturator through an indirect steam heater 302. Crystal slurry withdrawn from the base of the crystallizer through a line 316 also with a pressure-reducing orifice and throttling valve passes through a settling cone 318 and overflow pipe 320 back to the saturator, deposited crystals being centrifuged and dried, the mother liquor collecting in a storage tank 334 which also receives liquor from a tar skimmer 352 supplied from an overflow 344 from the saturator through a U-shaped seal 348 to which make-up acid is introduced.  A pump 368 connected to the tank supplies a downwardly directed spray 372 in the gas riser from the saturator which leads to a mist separator 236 in the outlet pipe.  Specification 669,425 is referred to.

Abstract: 791,408. Automatic gramophones. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Nov. 7, 1955 [Nov. 10, 1954], No. 31779/55. Class 40 (2). In a record changer, a centre spindle for records having a large centre hole, comprises a housing having a pair of main supports for the stack bevelled on the under sides and a pair of separator supports all of which are operated by a pin journalled in the spindle, characterized in that the main supports are provided with an aperture constituting an abutment for an operating pin provided on a lever pivoted in the housing and having a second pin engaging a plate-like body connected to the control pin. In the embodiment described with reference to Fig. 1, main supports 12 and separator supports 10 are separated by a plate 7 having apertures 19 which engage pins 18 of levers 15 pivoted on pins 20 in the housing. The levers 15 have pins 17 engaging apertures in plates 10 which are thereby pushed out or retracted when the plate 7 is moved transversely by the central control pin 5. The supports 12, however, have enlarged apertures 23, whereby the pins 16 on levers 15 are only positively effective to retract the supports 12, the return motion being effected by springs 14. Thus an element of lost motion is produced whereby records may be withdrawn from the spindle when the supports 12 are caused to be retracted by pressure of the record against the bevelled surfaces of the said supports 12.

Title: Production of organosilicon compounds
Inventor: KELLY PATRICK MCAVOY
IPC: C08G77/06
Filed: 1964-08-05
Abstract: Novel complexes of a platinous halide with a silicon compound contain at least one Sibonded allyl or vinyl group, and are prepared by direct reaction of the components, or by olefin interchange after having first prepared a complex of a platinous halide with another olefinic compound.  Suitable halides are the bromide, chloride and iodide.  The silicon compound of the complex may contain other organo groups, such as methyl, phenyl or cyclohexyl.  In addition, copolymers consisting essentially of dimethylsiloxanyl and methyl-vinylsiloxanyl units are eminently suitable.  A use of such complexes is in the process of preparing organosilicon compounds which comprises reacting together an unsaturated organic compound and a silicon compound having at least one and not more than two silicon-bonded hydrogen atoms, in the presence of such a complex as catalyst.  By "unsaturated compound" is meant any compound having at least one pair of C atoms linked by a multiple bond, with the exception of aliphatic amines, aldehydic compounds, and compounds having a CN group directly attached to an unsaturated C atom.  The Si-H group and the carbon unsaturation may be embodied in one compound. The Si-H compound may be mono- or polymeric, and includes halogenosilanes, organohalogenosilanes, polysilanes, polysiloxanes and polysilcarbanes.  The organo groups in such compounds may be alkyl, cycloalkyl, aryl, aralkyl, alkaryl, alkenyl, cycloalkenyl or haloaryl; they are preferably methyl or phenyl. Preferred compounds have the formula RaSiHbX4- ab where R is a hydrocarbon group, X is halogen, alkoxy or aryloxy; a is 0, 1 or 2; b is 1 or 2 and a + b does nor exceed 4.  Hydrolysis products of the above sieanes may also be used. The unsaturated compound may be purely organic, or may be organometallic (e.g. organosilicon). They include hydrocarbons, preferably with 24 or less C atoms, esters of unsaturated acids or alcohols, and mono- and polymeric organosilicon compounds.  The catalyst is used in an amount between 10- 2-10- 8, preferably 10- 4-10- 6 moles per mole of unsaturated reagent. Reaction temperature is not critical; and reaction time varies. Pressure may be atmospheric or above.

Title: Improvements in or relating to television receiver line oscillators
IPC: H04N5/12
Filed: 1960-09-16
Abstract: 967,546. Automatic frequency and phase control systems. BLAUPUNKT-WERKE G.m.b.H. Sept. 16, 1960 [Sept. 17, 1969], No. 31894/60. Heading H3A. The frequency of a line oscillator in a television receiver is controlled automatically by a voltage fed via a resistance-capacitance combination having two capacitors of different value which may be selectively connected by switch means operated automatically in accordance with the lack of synchronism to alter the time constant of the resistance-capacitance combination. As shown, the frequency of a line oscillator 1 is controlled by a valve 2 fed from a phase comparison circuit 5 to 9 via a R.C. circuit 3, 4. The phase comparison circuit receives line synchronizing pulses from a pulse separator 10 and via resistor 12 a portion of the output of the oscillator 1. The capacitor 4 has a low value in order to give a large operating range. A further capacitor 13 of much higher value may be connected across the capacitor 4 through a diode switch 14 controlled by a rectifier 19 receiving a positive bias via potentiometer 24, 25, 26 and terminal 27, and positive pulses 28 via a winding 29 on a transformer of the line oscillator. The anode of the rectifier 19 is fed with positive pulses 21 from the pulse separator 10 and the arrangement is such that when the pulses 21, 28, coincide no rectification takes place in the rectifier 19 and the diode 14 conducts to connect the capacitor 13 across the capacitor 4. When the pulses 21, 28 do not coincide, rectification takes place at 19 and the resulting negative potential blocks the diode 14.
