A thermal storage space heater comprises an upper part 1 covered by insulant 11 containing a storage core 10 with embedded resistances 16 and a U-shaped heating duct 8, and a lower part 2 containing a tangential fan 3 and inlet and outlet apertures in a common external face. Inlet air passes through grid 13 and filter 14 along intake passage 9 to blower 3 to be delivered to region 17, wherefrom part flows through U-shaped duct 8 to be heated and the remainder, controlled by hinged flaps 7a, traverses by-pass duct 7 to mingle with the heated air in chamber 18 before being expelled through humidifier 15 and exit grid 12. The exit grid 12 has upwardly curved transverse slats to prevent heated air being drawn into the inlet. The air passage through the heater decreases in area from inlet to outlet.

A bed 9 carries the worktable 16, which is traversable and rotatable by a motor M, and the columns 26, 27 which can be adjusted on the bed by means of independent motors M<SP>2</SP> and rack and pinion drives. The cross-rail 30 is vertically adjustable on the columns by a reversible motor M' mounted on the arch and driving a splined shaft 31 geared to lead screws 125 and 126. To allow for movement of the columns the arch 60 is connected to them by dove-tail slides and the saddles 63, 64 have vertical slides connecting them to the cross-rail ; the saddles carry nuts 127, 128 engaged by the screws 125, 126.

A turning, boring and facing head 36 is mounted on the column 26 and another head 38, similar to the head 36 but having a swivel mounting, slides on the cross-rail. The cross-rail and the heads 35 and 36 are counterbalanced by weights connected to chains 49. The traverse of the heads 36 and 38 and the axial feed of their rams 45 and 48 are driven from the work-table motor M by shafts 90, 91, 92. By means of a pair of bevel gears 93, 94 loosely mounted on the shaft 92, a clutch 95, a shaft 96 and clutches 97 and 98, the head 36 can be traversed in either direction by rotating a nut 101 on a stationary lead screw 102 or its ram 45 can be fed axially in either direction by rack and pinion gearing 104, 106 ; for imparting rapid movement to the head and ram, a reversible motor M<SP>5</SP> may be connected to the drives by means of the clutches 97, 98. A similar arrangement of drives and clutches connected to the shaft 92, and a reversible motor M<SP>6</SP>, operate the head 38 and ram 48 by means of a rotating lead screw 118 and a splined shaft 117. Clamps are provided for locking the various parts in their adjusted positions and may be interconnected with the driving arrangements so that the latter cannot be operated while the clamps are engaged.

Title: Improvements in upgrading crude petroleum oils
IPC: B01J8/12
Filed: 1958-07-01
Abstract: A crude petroleum oil is hydrogenated by causing it to flow upwardly in the reaction zone countercurrently and in contact with a down-flowing solid hydrogenation catalyst in the form of beads of size 1/8 -\ba1/16 inch, feeding a hydrogen-containing gas to the reaction zone, maintaining a temperature, pressure and oil residence time sufficient to cause the desired hydrocracking reaction and recovering from an upper point in said reaction zone hydrocracked products, continuously withdrawing catalyst contaminated with carbonaceous and other deactivating deposits from a lower point in the reaction zone, charging the withdrawn catalyst into a stream of an oxygen-containing gas in which deactivating deposits are burned from the catalyst while the latter is maintained as a confined stream and returning the regenerated catalyst to an upper point in the reaction zone for re-use.  The catalyst may be cobalt molybdate, nickel, platinum or nickel-sulphidetungsten sulphide, all on alumina, may be used. In a preferred embodiment, a bachaquero crude oil was treated at 850 DEG  F., 800 p.s.i.g., a space velocity of 0.5 v/hour/v., and a hydrogen feed of 3000 S.C.F/barrel.  The product consists of a lower boiling oil 45% of which boils at 650-1000 DEG F. and of a reduced sulphur content.  The catalyst may be regenerated at 975-1100 DEG  F. at a pressure of 100-1000 p.s.i.g. and with a residence time in the generator of 1-30 seconds.

Abstract: 1,262,118. Triangular wave generators. EASTMAN KODAK CO. 24 April, 1969 [26 April, 1968], No. 21049/69. Heading H3T. [Also in Divisions G2-G3] A triangular wave generator comprises a flipflop 100 providing a positive or zero potential F which is fed to a summing junction of an operational amplifier 101 which has a large feedback capacitor C 1  and thus acts as an integrator. NPN transistors Q 1 , Q 2  serve as power amplifiers and inverters. The collector of transistor Q 1  is connected to an enabling input J of the flip-flop 100 so that when the voltage at input J reaches the triggering level, the next pulse from clock pulses applied to an input C causes the flip-flop to change state. The collector of transistor Q 2  is connected to a second enabling input K. Variation of the value of capacitor C 1  adjusts the frequency of the triangular wave produced at the output of the operational amplifier 101. The output may alternatively be taken from the collector of either Q 1  or Q 2 .

Abstract: 714,811. Transistor amplifying circuits. WESTERN ELECTRIC CO., Inc. Aug. 22, 1952 [Sept 13, 1951], No. 21127/52. Class 40 (6) An amplifier circuit comprises two transistors of opposite conductivity type having a first pair of like electrodes connected together and a direct-current source connected between a second pair of like electrodes, the input signal being applied between the second and third electrodes of one transistor and the output signal being taken from between the first and second electrodes of the same transistor. The transistors used may be of either the point type or junction type. Thus Fig. 1 shows two junction-type transistors of opposite conductivity type, i.e. the intermediate zone of transistor 10 is composed of N-type material while that of transistor 11 is composed of P-type material. The collectors of the two transistors are connected together while the transistors are biased by a battery 16 connected across the two emitters. The signal input is applied via a transformer 18 between the emitter and base of the transistor 11 and the output signal taken from the terminals 19. An auxiliary biasing source 17 is provided to ibias the base of the transistor 10 correctly. In a modification, Fig. :2 (not shown), employing point-type transistors the input signal is applied to the two base electrodes in parallel, blocking condensers and choke coils being used as required. In these embodiments each collector presents a high impedance to the other so that a high voltage gain is obtained. The currentamplification factor is preferably chosen to be close to unity so that a large change in collector current is obtained for a small change in base current. Fig. 3 shows a further embodiment having a low output impedance in which the emitters are connected together, the input signal being applied to the two bases in parallel and the output being taken from the terminals 19.
