Title: An improved process for distilling and cracking hydrocarbon oils
IPC: C10G9/00
Filed: 1921-02-08
Abstract: 179,644. Gartlan, S. L., and Gooderham, A. E. Feb. 8, 1921. Hydrocarbons, distilling; hydrocarbons, cracking. - In distilling and cracking hydrocarbon oils bv vaporizing the oil at about atmospheric pressure, and compressing and condensing the vapours under pressure, the pressure is increased during the course of the distillation so that the heavier vapours coming off at the later stages are cracked by the heat generated by the compression and a uniform distillate is obtained. The still a, heated by burners l, is supplied with oil through a tube c from a vessel b in which it is mixed with steam from a generator d by a rotary stirrer e<1> to heat the oil to about 40‹ C. The vapours generated in the still are withdrawn by a compressor f and are passed through a condenser h and receiver still under pressure. Uncondensed gases pass by a pipe k to the burners. When the evolution of vapour in the still ceases and the pressure falls below atmospheric, the temperature of the still is raised step by step and is maintained after each rise until evolution of vapour ceases. When the oil has reached a cracking temperature (about 300‹ C.), steam, superheated by passage through a heated tube o, is passed into the still. The compressor is operated so as to maintain a pressure of about 125 lb. per sq. in. in the receiver until a temperature in the still reaches 300‹ C., and the pressure in the receiving tank is raised about 25 lb. per sq. in for each subsequent increase of 100‹ C. in the still.

Patent GB-647194-A (GB)
Title: Improvements in or relating to record card controlled calculating machines
IPC: G06F7/44
Filed: 1947-02-17
Abstract: 647,194. Statistical apparatus. BRITISH TABULATING MACHINE CO., Ltd., and BAILLIE, G. H. Feb. 17, 1947, No. 4602. [Class 106 (i)] A record card controlled machine in which relays are operated by impulses derived from the sensing of a record card is characterized by a circuit arrangement in which the impulse resulting from the sensing of a record in a given position on a card operates so as to set up a predetermined value on one or more value registering relays, and in which the impulses derived from the sensing of records in other, subsequently sensed, positions in the same column of the card are adapted to vary the circuit so that one of at least three different arbitrary values of which one value at least is multi-denominational, is set up in the value registering relays, the value finally registered being read out to control a recording, adding or multiplying device. A commutator brush 7 moves over a common bar 6 and individual contacts 8 in synchronism with the passage of a card between a reading brush 2 and conducting roller 1. Thus, if there is a perforation in the " 9 " position, a circuit is completed from positive line 4, through a contact breaker 5, common brush 3, roller 1, brush 2, bar 6, contact 9, relay R1 to negative. Relay R1 closes contacts R1b to establish a holding circuit, and contacts R1a which complete a circuit through contacts R3c, R2c to two relays representing the arbitrary amount 1s, 2d. If a second hole is sensed in position " 8 " in the card, relay R2 becomes energized and so changes the circuit that relays representing the arbitrary amount 2s, 4d become energized instead of those previously operative. Similarly the sensing of a hole in the " 7 " position causes the amount registered to be changed to 2s, Od, while a fourth perforation in the " 6 " position registers the original amount 1s, 2d. A hole in the " 5 " position, causing energization of a relay R7, may control the addition of an arbitrary amount to the amount registered. Further commutators 11, 12 (shillings) and 13, 14 (pence) read out the amount registered in the relays and, through magnets R5, R6 control printing or punching devices, or a multiplying, relay controlled network such as that described in Specification 599,767.

Title: Process of brewing
IPC: C12C7/28
Filed: 1966-02-02
Abstract: 1,132,251. Reconstituting wort concentrate. JOS. SCHLITZ BREWING CO. Feb. 2, 1966 [Feb. 8, 1965], No.4665/66. Heading C6E. Wort concentrate is reconstituted by continuously flowing a stream of concentrated wort having a solids content above 78% e.g. 80%, through a closed system at a substantially uniform rate and continuously mixing a stream of water with the concentrated wort to reconstitute the wort. Any slight adjustment of the specific gravity of the reconstituted wort may be made in the fermenting tank. In a preferred procedure, the stream of water is mixed with the wort concentrate by continuously introducing a first stream of water (de-ionized water or filtered mains water) into the flow path of the wort at a substantially constant flow-rate to partially reconstitute the wort, and subsequently continuously introducing a second stream of water into the partially reconstituted wort to completely reconstitute it. The flow-rate of the first stream of water is typically 6 to 8 times that of the second stream of water. The flow of the second stream of water is regulated in accordance with a measurement of the density of the reconstituted wort to ensure a uniform density of the reconstituted wort. The wort concentrate is at a temperature below 120‹ F. and the first and second streams of water are at temperatures within range 150‹-210‹F. The reconstituted wort is maintained at a temperature above 140‹ F. for a period of time sufficient for pasteurization and is then immediately chilled to a temperature below 75‹ F. by flowing it in heat exchange relation with chilled water; the heated water is further heated, by heat exchange with steam, to a temperature within the range 150‹- 210‹ F. and subsequently is utilized for the first and second streams. Air is introduced into the reconstituted wort in accordance with a measurement of its oxygen content in order to maintain a substantially uniform oxygen content in the reconstituted wort and hop bittering constitutents are added to obtain a desired bitterness level. An allmalt, unhopped or lightly hopped wort concentrate may be blended with a concentrate or syrup or adjuncts prior to the reconstitution with water. Provision may be made for the system to be automatically flushed clean, should the density or temperature of the reconstituted wort vary beyond predetermined limits.
