Title: Arrangement comprising a mechanical memory for conveyoroperated storage and or sorting systems
IPC: B07C3/00
Filed: 1966-05-26
Abstract: 1,092,981. Endless conveyers. ELECTROLUX A.B. May 26, 1966 [May 26, 1965; Aug. 26, 1965], No. 23552/66. Heading B8A. A mechanical memory (18) (Fig. 1, not shown) for controlling the distribution of articles from a conveyer belt (10) to branch conveyer belts (11), (12), (13) . . . (14), comprises a drum 19, rotatable in synchronism with the conveyer belt 10, and having a number of axially spaced rows I, II, III . . . , of indentations 20. Each of the latter is adapted to convey a ball 21 along a channel 22 there being a respective one of the latter corresponding to each row I, II, III . . . . The balls collect in the channels 22 at a series of solenoid operated gates BU 01 , BU 02 , BU 03  ... respective to each channel. These gates are released according to the operation of keys (D 01 ), (D 02 ), (D 03 ) . . . (Figs. 10a, 10b, not shown) or alternatively depending on the setting of a switch (A8) by a punch card mechanism (A). The latter programmes the solenoid operated gates (BU 01 , &c.) automtically via relays (AO)-(AN). This permits a ball in the channel 23 concerned to fall until stopped by either a stop BM1-BM5 (there is one of each of these for each channel 23 (Figs. 6-8, not shown), or if the memory has not completed a previous programme, by a gate BM0. When the first article on the conveyer belt (10) reaches a micro switch (C6), the gate BM0 is withdrawn to permit the ball to proceed to a point in the associated channel 23 in which it can be entrained by a recess 20 of the drum 19. When the ball operates a switch B11S, B12S or B13S according to which branch conveyer (11), (12), or (13) the article in question has been programmed for, a stop (C9) on the conveyer belt (10) is raised and the article is allowed to proceed. The article then sequentially operates a series of micro-switches (C5)- (C0) The switches (C5)-(C1) operate to deenergize in succession solenoids of stops BM5- BM1, and switch (C0) operates a stepping switch (E) in a minus sense. The latter is operated in a plus sense by every signal originating either from the keys (D01) &c. or the punch card device (A). The stepping switch (E) activates the stops BM5-BM1 via a series of relays (E 1 )-(E 5 ). In this way a series of balls are collected by the stops BM1-BM5 in each of the channels 23 and this constitutes a memory of a programme as set manually on the keys (D01), (D09), &c. or by the punch card device (A). In a modification (Figs. 11, 12 not shown,) the rows of recesses 20 are replaced by a single spiral groove in the periphery of the drum 19. Each channel 23 is replaced by a channel (105) (one in respect of each branch conveyer belt) disposed axially of the drum 19. The branch conveyer belts (11), (12), (13) . . . may be replaced by discharge stations of the conveyer belt (10).

[Class 7 (ii)] In means for supplementing the normal fuel air mixture by a gas mixture of oxygen and hydrogen produced in an electrolytic gas generator connected-to the battery dynamo circuit of the engine the gas generator is incorporated in the battery which supplies the electrical equipment of the engine, and plates of electrolytically inert material are attached to the plates of the battery. As shown, perforated carbon plates b are attached to the plates of a battery a. It is stated that the current flowing through the battery will be divided between charging the battery and decomposing some of the water content of the electrolyte into oxygen and hydrogen. The oxygen and hydrogen are collected in a space d after passing a filter e and then pass either by a pipe h to a carburetter j on a pipe k direct to the engine induction pipe. Alcohol may be added to the electrolyte of the battery so that the mixture of oxygen and hydrogen will be enriched as it bubbles through the alcohol.
