Abstract: 589,792. Bed-settees. GILES, E. F. April 5, 1945, No. 8464. [Class 52 (ii)] A chair is convertible into a bed by the telescopic extension, in opposite directions from a middle seat-supporting part, of sides which in the retracted position form the arms of the chair, and comprises a folding three-sectioned mattress-supporting frame of which the end sections are hingedly connected to opposite sides of the middle section and are adapted to be folded inwardly in flat alternate overlapping relationship with the middle section or opened outwardly so as to provide with the middle section a continuous substantially coplanar mattress-supporting structure extending between the sides and across the middle seat-supporting part when the sides are extended to form a bed. As shown in Figs. 1 and 3 the arm rests 2, 3' of the chair are attached to guide bars 4, 6 slidable along slots in the front and rear members of the central portion 1 of the chair. The mattress-supporting frames are of angle iron and normally rest beneath a seat cushion 22, two other cushions which serve for the mattress being stowed in the arm rests. To convert the chair into a bed the arm rests are extended laterally, the extent of movement being limited by stop pins on the guide bars 4, 6 and the end sections 11, 12 of the supporting frame are swung clear of the centre section 10 to provide a flat frame for the reception of the cushions 22. The frame sections are each provided with a central ring 13 connected to the side members by chains and springs 14, 15, respectively. In the embodiment according to Fig. 4, the sections of the mattress and supporting frame are housed in the chair back 31, which is swung forwardly about pivots 32 and locked in position by member 40 to provide support for the centre section 10. In this form the three cushions 22 used as a mattress are normally housed in the centre portion of the chair.

Title: Improvements in repeating polyphase circuit interrupters
Inventor: RYAN ANTHONY VAN
IPC: H01H75/04
Filed: 1955-03-25
Abstract: 776,244. Automatic reclosing circuitbreakers; protective cut-out arrangements. McGRAW ELECTRIC CO. March 25, 1955, No. 8843/55. Class 38(5) An automatic reclosing polyphase circuit interrupter has overload responsive means and earth fault responsive means both with normally quick response and for controlling opening means, first and second time delay means for delaying response of the overload means and earth fault means respectively after a predetermined number of operations in rapid succession, and means for ensuring independent operation of both time delay means so that no opening operation can be delayed by more than one time delay period. The interrupter described is that of Specification 776,243 with the addition of the earth fault means.and the means for ensuring independent operation: The earth fault means has a coil 166 energized by the residual current from current transformers (not shown), associated with the respective phase conductors. When the coil is energized, a plunger 183 is drawn down against the bias of a spring 199 to compress a spring 185 interposed between the plunger and a shoulder 187 on a rod 184. The rod is then moved downwardly by the spring 185 at a speed independent of the magnitude of the earth fault current and turns a lever 201 to turn a latch 203 to release a spring biased toggle 204, 214. The toggle collapses, and turns a shaft 213 so that a lever (not shown), on the shaft moves the trip bar to cause the tripping of the interrupter. The toggle' 204, 214 is reset during the opening operation by a pin 222 on a switch operating lever 15 engaging a member 226 on the shaft 213. After a predetermined number of opening operations, the sequence bar 59 is moved sufficiently for a cam 206 to release a lever 208. A valve 194 is now closed by a spring 195 to prevent free communication between the parts of a cylinder 190 above and below a piston 189 secured to the rod 184. Any further action of the earth fault means is now delayed. When the toggle 204, 214 collapses, it moves a bar 217 so that a pin (not shown) carried by it prevents the interconnection of the first time delay means (i.e. that associated with the overload responsive means) with the trip bar so that after a delay imposed by the piston 189 (the second time delay means), no further delay can be imposed by the first time delay means when delayed tripping occurs under earth fault conditions. Also. as the lever on the shaft 213 (referred to above) merely engages a pin on the trip bar, the second time delay (due to piston 189) cannot be added to the first time delay when tripping occurs under overload conditions. In a modification, Figs. 38 and 39 (not shown)', the rod 185 may optionally be locked to the plunger 183 so as to make the time delay inversely dependent on the magnitude of the earth fault.

Title: Catalyst regeneration process
IPC: C10G11/00
Filed: 1975-03-04
Abstract: 1499682 Fluid catalytic cracking STANDARD OIL CO 4 March 1975 [4 March 1974] 8885/75 Heading C5E [Also in Division B1] In a cyclic catalytic hydrocarbon cracking process wherein deactivated catalyst is withdrawn from the reactor, stripped, regenerated and recycled to the reactor, the regeneration comprises (a) fluidizing the deactivated catalyst, in physical association with a carbon monoxide-oxidationpromoting catalyst of a metal of At No. of at least 20, with a molecular oxygen-containing gas so as to burn substantially all coke from the catalyst and convert substantially all of the carbon monoxide produced to carbon dioxide, most of the heat so produced being absorbed by the catalyst particles and the temperature being maintained at from 1000-1500‹ F.; and (b) withdrawing an effluent gas containing not more than 1À0 vol. per cent of carbon monoxide and regenerated cracking catalyst containing absorbed heat and having no more than 0À10 wt. per cent residual coke. The initial coke combustion and the carbon monoxide oxidation may be effected in a single dense phase bed or the former may be effected in a dense phase bed and the latter in a dilute phase bed. The oxidation catalyst may be metallic or oxidic and may contain Zn, Ce, U, Ti, Zr, Bi, Cr, Mo, W, Mn, Fe, platinum metals or heteropoly oxides. It may be present, either supported or unsupported, in physical admixture with the cracking catalyst or may be impregnated thereon. The cracking catalyst may be a crystalline aluminosilicate in a silicaalumina matrix. The cracking process may use a feed boiling above the gasoline boiling range, e.g. at 400-1200‹ F. such as light or heavy gas oils, wide-cut gas oils, vacuum gas oils, kerosenes, decanted oils, residual fractions, reduced crude oils or cycle oils derived from these or fractions from shale oil, tar sands processing, synthetic oils and coal hydrogenation. Suitably, cracking is effected exclusively in a 'riser' reactor at 950-1000‹ F. with a contact time of 3-10 secs., a throughput ratio of 1 to 2, and a catalyst to oil weight ratio of 2 to 10. Spent catalyst may be stripped at 850-1050‹ F. with steam, nitrogen or flue gas at 10-35 p.s.i.g.

Title: Liquid level gauging system
IPC: G01F23/44
Filed: 1953-04-01
Abstract: 741,181. Liquid level gauging device. JURS, A. E., sen., YOUNG, R. M., JURS. E. E., JURS, P. C., and JURS, jun., A. E., [trading as SHAND & JURS CO.]. April 1, 1953 [Sept. 2, 1952], No. 9056/53. Class 40(1) A system for producing indications at a reading station corresponding to the portion of an element of a remote measuring device, in which the latter comprises a member displaced an amount proportional to the displacement of the element, means for driving pulsing contacts and simultaneously displacing a second member from a starting position, means for energizing the driving means to initiate a number of pulses which is fed to means at the reading station to position an indicator in response to the number of pulses relative to that of the first member, and means for returning the second member to its base position. A switch S or equivalent relay or group of relays at the reading station may control the transmission of a starting signal to energize the driving means and also of signals to re-set the indicator and return the second member to its base position. A single line can be used for two measuring devices the senders being controlled by positive and negative starting impulses respectively Fig. 3 (not shown). Detailed operation. On the operation of switch S to the right a momentary circuit is made over contacts 1, 3 for a solenoid 28 at the remote station. This releases an arm 24 and operates a switch 44 Which starts a motor 29 which drives an impulse transmitter 38 connected to the driving magnet 71 of the indicator 62 until the arm 24, which is geared to the impulse transmitter reaches a stop 39 on an arm 23 geared to a float 12. A switch 43 is then operated and stops the motor. When switch S is moved to the left, a momentary circuit is again made over contacts 1, 3. This operates a solenoid 40 which retracts the stop member 39 from the path of arm 24 and starts motor 29 again. Arm 24 is thus driven to its normal position where it is held by latch 27 and operates switch 47 to stop the motor. Switch S also operates the release magnet 74 of the indicator. It is then restored to its mid position in which no circuits are closed. In a modification, Fig. 2 (not shown) a thermionic amplifier . is provided for the impulses received at the reading station.

Title: An improved instrument for the comparison of the intensities of light rays
IPC: G01J1/36
Filed: 1927-04-02
Abstract: 298,094. Neale, J. April 2, 1927. Photometric apparatus.-In apparatus utilizing a photo-electric cell for the comparison of the intensities of the light rays from two sources, intensities of the light rays from two sources, or from a single source through two media, one of which may be a standard, the rays are caused to fall alternately on the cell and the, corresponding and resultant currents are passed by means of a reversing current distributor through an indicator or recorde, such as a. galvanometer. For the comparison of densities light from a source A passes through apertures in a shield B and through lenses by which the beams are rendered parallel on to a rotated disc D having an aperture F. Mirrors G reflect the beams through the objects under test on stands L to the cell K. The disc D is rotated by the motor E on the shaft of which is a reversing current distributor N arranged so that the current from the cell K through the galvanometer is reversed at each half-revolution. No deflection results if the lighttransmission through the two objects is equal, but any difference is indicated by a deflection on the galvanometer M. In comparing colours the light reflected from the material impinges on the photo-electric cell.
