Patent GB-870771-A (GB)
Title: An automatic machine for the continuous packaging of articles such as vials and the like in corrugated bands
IPC: B65B15/04
Filed: 1959-04-08
Abstract: 870,771. Packaging. BREVETTI C. E. A. S.p.A. April 8, 1959 [April 22, 1958], No. 11808/59. Class 94(1). A machine for packing vials &c, in the compartments of a corrugated strip 18 comprises a sloping table down which the vials slide to enter grooves in a guide member, a ram pushing successive batches of vials into the strip. The filled strip is cut into lentghs at regular intervals. Vials 15 are massed on the table 13, supported on their lower ends, and the foremost row, the length of which is adjustable by moving a guide 11 and integral side wall 17, enters grooves in a plate 14a. The grooves diverge upwards to correspond at their exits to the strip compartment spacing. A ram 25 carried on a reciprocating member 24 forces the first row into the strip, the following row being restrained by a rail 21. Movement of the member 24 causes lever and slideway means 30-33, 35, 36, to operate knife members 35a, 40 to cut off a previously filled length of strip. Movement of the member 35a rotates a cylindrical pinion 42 to advance a gripper 45 attached to a rack 44, the gripper having pins 46 which engage in a strip compartment. The gripper is then shifted longitudinally by a cam operated lever 54 to advance the strip for the next filling operation. The stroke of the lever, and thus the strip advance, is adjustable. The plate 14a may be interchangeable for different size vials.
Patent GB-1036172-A (GB)
Title: Sewage disposal system
IPC: C02F3/30
Filed: 1964-03-20
Abstract: <PICT:1036172/C1/1> Sewage enters chimney 16 and circulates in lower chamber 12, where anaerobic digestion occurs and then passes at 20 into upper chamber 11 where aerobic digestion occurs. Aspirator-circulator 30 (Fig. 2, not shown) comprises cylinders 32a, 32, in the upper and lower chambers respectively, which rotate with a hollow shaft 33. Radial passages (45), (46) and external lugs (Fig. 3, not shown) on the cylinders induce a flow of air down shaft 33 and into the sewage as the shaft is rotated by motor 35 (at 1750 r.p.m.). About 90% of the air is bubbled into upper chamber 11, the remainder into chamber 12.  In addition, cylinder 32 rotates in a sleeve(s) fixed to the dividing floor 13, and has a helical external groove (47), whereby rotation pumps a little sewage from chamber 11 back to chamber 12, "facultative digestion" occurring in chamber 12 around where the sewage from chamber 11 and the air enter.  Another aspirator unit 44 aerates the sewage in chamber 53, and the almost entirely liquid effluent leaves at 70. A heater 41 is used only after solids have accumulated in chamber 12 for several years, and maintains the sewage at 90 DEG  F.  "Facultative digestion" is stated to occur in a largely anaerobic environment containing small quantities of oxygen.

Title: Improvements in self-adjusting brakes for vehicle wheels
IPC: F16D65/52
Filed: 1931-04-23
Abstract: 386,960. Adjusting brake shoes for wear. TURRINELLI, G., 2, Via Berchet, Milan, Italy.-(Assignee of Barzano & Zanardo; 6, Via Gesu, Milan, Italy.) April 23, 1931, No. 12080. Convention date, May 20, 1930. Void [Published under Sect. 91 of the Acts]. [Class 103 (i).] An automaticallyadjustable stop device for brake shoes to maintain the normal clearance from the drum is independent of wear of the friction surfaces comprises a lever M<1> on a fixed pivot A provided with a slot at F through which passes a pin on the brake shoe M. A fixed bolt H passing through a second slot in the lever serves to tighten friction washers against the sides of this slot so that the return spring N is unable to move the lever. If, due to wear, the shoe moves during application an amount greater than that permitted by the slot at F, the lever is moved and the excess of play is taken up. The application to a brake shoe carried by a lever and applied to a vehicle wheel is also shown. In the case of a hydraulic brake system provided with the above device a reservoir is provided to supply the additional liquid to the system due to the increase of capacity of the brake cylinder as wear occurs. In a hand-applied brake the hand-lever drives the brake shaft through a ratchet and pawl, the pawl slipping a tooth on the return stroke as wear is taken up by the above-described device, so that the stroke of the hand-lever is maintained substantially constant.

Filed: 1947-05-06
Abstract: 627,644. Generating combustion products under pressure. MORDELL, D. L. May 6, 1947, No. 12265. [Class 51 (i)] [Also in Group XXVI] In an annular combustion chamber of a gas turbine plant the air and fuel are given a swirling motion in radial planes about an axis which is a circle concentric with and lying within the combustion chamber. Air from the delivery 5 of the main compressor is conducted by pipes 13 to the eye of a centrifugal compressor 10. Fuel is injected into this air either at the inlet eye or, as shown, from pipes 14 into the pump outlet. The air-fuel mixture is deflected upstream by an annular baffle 15 and the circular crosssection 9a of the end of the chamber supports an annular eddy. Secondary air admitted at ports 16 is guided tangential to the eddy. Part of the delivery of the compressor 10 may be divided off by the inner part 15a of the baffle and directed to the space between the walls, 7, 9b. In an alternative form, the delivery of the compressor 10 may traverse the combustion chamber and be deflected upstream by a baffle on the outer wall of the combustion chamber. According to the Provisional Specification the air and gas mixture is directed across the combustion chamber by spaced segmental guides. Also in a plant with a reheating combustion chamber between the turbine stages, the primary air may be taken from the highpressure compressor delivery.

Title: Data communications system and its method of operation

Abstract: 1470883 Data transmission; error correction TEXAS INSTRUMENTS Inc 22 March 1974 [2 April 1973] 12864/74 Heading H4P In a communication system a transmitting station 10 or 11, Figs. 1 and 2, transmits blocks of data including an identification code for each block of data to a receiving station 11 or 10 without waiting for acknowledgements of preceding blocks from the receiving station, and the receiving station stores the identification codes of those blocks of received data which contain an error and transmits to the transmitting station a message including the identification code of each block of received data and a response portion to indicate whether the block was received correctly or contained an error. The transmitting station is then responsive to the identification codes received from the receiving station to retransmit to the receiving station only those blocks of data which contained errors. Each station 10 or 11 includes both a transmitter and a receiver unit 15 to provide duplex operation over lines 22. The transmit-receive unit 15 includes a data concentrator and computer interface unit (20, Fig. 4, not shown) which is disclosed in detail (Figs. 5 and 6, not shown) and includes a parity check function (51) and a transmitter receiver (21) which is also disclosed in detail (Figs. 7 and 8A, 8B, not shown). Each station 10, 11 has a computer 12 which includes a central processor 17, a memory unit 18 and a direct memory access 19. The received blocks of data at the receiving station are checked to determine blocks containing errors. This checking is performed by a cyclic redundancy comparison of the data with a cyclic redundancy code transmitted by the transmitting station. Logic circuits including shift registers (101 Figs. 9A and 9B, not shown) are used in the transmitter and receiver respectively to perform the cyclic redundancy check. In checking the received data the numeric binary value of the data block is divided by a constant and the remainder of the division is compared with a remainder provided by the transmitting station for the same block of data. At the transmitting station the numeric binary value of each data block is divided by a constant and a code representative of the remainder of such a division is transmitted to the receiving station. If the number of retransmissions of the incorrectly received block exceeds a preset value such as three an equipment failure is indicated.
