Title: Electrolytic process for producing aluminium and aluminium alloys
IPC: C22C1/02
Filed: 1925-10-05
Abstract: 242,958. Haglund, T. R. Nov. 15, 1924, [Convention date]. Aluminium and alloys, obtaining.-Aluminium and its alloys are obtained by electrolysis of a molten electrolyte compounded of crystalline aluminium oxide of high specific gravity, such as that formed by crystallization from a melt, e.g. corundum, and amorphous aluminium oxide of lower specific gravity, e.g. such as is obtained by calcination of the hydrate or salts of aluminium. The crystalline oxide must be of sufficient purity to be used for the production of aluminium of common commercial quality when subjected to electrolysis in the presence of a molten electrolyte. The use of the mixture is stated to minimize the formation of a solid crust on the molten bath and prevents blowing away of the amorphous alumina. A proportion of 10 to 40 per cent of amorphous oxide to the whole is suitable. The oxides may be mixed before charging or added separately. In the latter case, the amorphous oxide should be added immediately after the crystalline oxide. Specification 232,189 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) refers to Specification 232,549, [Class 1 (iii), Oxides &c., Metallic]. This reference does not appear in the Specification as accepted.

Title: Improvements in liquid level indicators
IPC: G01F23/16
Filed: 1927-09-22
Abstract: 304,704. Lewis, W W., and Economic Car Light, Ltd. Sept. 22, 1927. Indicators actuated by pressure of head of liquid.-In a liquid-level indicator applicable to fuel tanks of motor vehicles, of the kind in which the air pressure in an open ended pipe dipping into the liquid is measured, a block A of ebonite is provided with a chamber B containing mercury, into which projects an iron pipe C communicating through a. passage D with the dip pipe. A bell E dips into the mercury and by means of a rack E<1> on its stem actuates a spindle F<1> carrying an indicating pointer. The top of the bell carries a cap H which is pressed upwards by a loose ring I and spring J. A transverse spindle M, actuated by an external handle, carries cams N engaging the cap H, N<1> engaging the ring I, and N<2> engaging a depending arm L‹ attached to a spring L carrying a pad L<1> closing the top of a pipe K. To take a reading, the spindle M is turned to depress the bell and expel air from the dip pipe, and a further rotation disengages the cam N from the cap H while the cam N<1> keeps the ring I depressed and allows the bell to move freely under the influence of pressure within. To renew the air in the system when required, the spindle M is turned to raise the arm L‹, spring L, and pad L<1> by the cam N<2>, while the ring I is also released and the bell raised to its hightest point by the spring J, the whole system being open to atmosphere through pipe K. Further rotation of the spindle M enables a reading to be taken as before. The scale reading is adjustable by a spindle P screwing into an auxiliary mercury reservoir O.

Title: Data receiving apparatus
IPC: H04L7/00
Filed: 1975-06-11
Abstract: 1517181 Data receiving apparatus WESTERN ELECTRIC CO Inc 11 June 1975 [17 June 1974] 24950/75 Heading H4L  Apparatus for receiving from first and second transmission paths a data word comprising a predetermined number N of bits, includes means for providing for utilisation the complete data word from one of the paths if the difference between N and the number of bits received from the other path is greater than a predetermined value D or, if the difference is equal to or less than D, for providing for utilization both complete data words after reception of the complete word from the other path. As described, identical data is transmitted along two data links A, B (A being 200m longer than B), data arriving via A 1À2 msec later than via B, equivalent to 3 bits in the embodiment described. Here N = 27 bits and D = 6 bits. The receivers for A and B are shown in Figs. 2 and 3. Data is received at modem MA (MB) and entered in shift register DSRA (DSRB) under the control of clock AIA (BIB) which synchronously enters 1's in "counter" registers CAI (CBI). Flip-flop FFA (FFB) detects when a complete word has been received, gate 210 (346) provides a signal PC22A=0 (PC22B=0) when the 22nd bit has been received, and gates 350-377 (301-327) gate the data word out of the register. (1) A-word more than 6 bits behind B- word. LBRFFB = 1 and PC22A = 1 so gate 41, Fig. 4 enabled to provide a signal DWGB which enables gates 301-327 for the complete word in DSRB. (2) A-word within 6 bits of B-word. Now PC22A=0, so gate 41 not enabled. When DSRA contains all 27 bits, LBRFFA = 1 to enable gate 42. Now gate 43 or 44 is enabled according as the second received bit was 1 or 0 (signal OEBIT). A signal GAAM or GBAM causes a differentiator 340 or 328, Figs. 7-8 (not shown) to set a flip-flop 341 or 329 to allow a clock A2A or B2B to read out the contents of DSRA, DSRB for bitwise comparison in an XOR gate 366, Fig. 3. If the two words are identical, FF337 is not set and gates 301-327 or 350-377 are enabled (gates 345. or 339). (3) "UNITARY" mode. Switch 45 provides a signal SMPX which enables gate 46 or 47 when a register contains a complete word, which is then gated out without comparison by means of signal DWGA or DWGB. (4) When the first bit of a succeeding word is received (bit 1 is a 0 which sets a FF 21 or 32) while a current word is in a register, that word is immediately gated out: gate 260 (380) provides a signal FBNWDA (FBNWDB) which, with signal LBRFFA or LBRFFB, enables gate 411 or 49 to provide signal DWGA or DWGB. (5) Discontinuity in transmission: if, e.g. the first bit of the A-word is received before the first bit of the B-word, while the 27th bit of the B-word has been received and the 27th bit of the A-word has not, then the complete received word is immediately gated out. XOR gates 261, 382 detect the presence of the 1st bit and the absence of the 2nd bit (signals PCIA, PCIB) and set FF414 or 415; the outputs from 414, 415 and signals LBRFFA, LBRFFB enable gate 416 or 417 to provide signal DWGA or DWGB.

Pallets 16, each carrying three stacks of trays 17, are fed into the apparatus by dogs 24 on an endless chain 19 which passes over a driving sprocket 21 on a shaft 20, over idler sprockets 22 and is guided on its upper run between rails 19a. The pallets 16 are supported on rollers 15 and and guided by edgings 18. The shaft 20 is coupled to a shaft 26 driven from the unstacking mechanism 12 over gearing, including an electrically operated singlerevolution clutch controlled by two switches 26c, 26e in series, one of which senses that the last tray 17 of a stack has been removed from the pallet 16, while the other senses that the last tray 17 is out of the way of the next stack (being deposited on a conveyer 11). When both switches 26c, 26e are closed the clutch is engaged and the conveyer 19 advances a new stack into unstacking position, thereby opening both switches and disengaging the clutch. The empty pallets 16 are conveyed through the apparatus to the stacking mechanism 13 by a pair of endless conveyers 27. An endless chain conveyer 119 is actuated in a similar manner to the conveyer 19 to advance the pallets 16 a distance corresponding to the desired spacing of the stacks under the control of another two sensing switches 126c, 126e.
