Title: Improvements in and relating to machines for moulding plastic material such as dough
IPC: A21C11/00
Filed: 1935-07-26
Abstract: 465,096. Moulding dough by rolling- machines. KREMMLING, J. July 26, 1935, No. 21332. Convention date, July 27, 1934. [Class 87 (ii)] In a machine for moulding plastic material such as dough of the kind comprising a rotary drum having peripheral mould recesses into which the dough is forced by means of a pressure or feeding roll and from which the dough shapes are extracted by an endless discharge band or conveyer, the adjacent surfaces of the drum and roll are spaced apart and a knife or scraping device having a portion transverse to the direction of the movement of the dough is positioned between the roll and the drum, the device together with the adjacent surfaces of the roll and drum forming a compression chamber for the dough. As shown in Fig. 1, a moulding drum 2 and a pressure roll 3 adjustable in slots 4 are mounted beneath a dough hopper 1, a blunt-ended knife or scraper 5 being adjustably mounted between the drum and the roll. The knife 5 bears with one of its edges against the drum 2 and may be provided with a recess 25 adjacent this edge to prevent the accumulation of dough. The roll 3 may be provided with longitudinal ribs or corrugations, the edge of the knife which bears against or is adjacent to the roll being bevelled to provide a surface parallel with the surface of the roll. The moulded shapes are removed from the recesses in the drum 2 by a conveyer 6 driven by rollers 7, 8 and travelling over an adjustable knife edge 9, these parts being carried by side plates 12 and removable from the machine as a unit. The shapes are fed from the conveyer 6 to a wire mesh delivery conveyer 14 by a small driven roller 19 situated between the conveyers. In a modification, in addition to the pressure roll 28, Fig. 4, moulding drum 20, and scraper 31, a counter feed roll 29 is provided, the space between the roll 29 and drum 30 being closed by a plate 38.

Title: Improvements relating to filters for liquids
IPC: B01D29/48
Filed: 1937-08-03
Abstract: 505,271. Filters. RIMELIN,B. Aug.3, 1937, No. 21342. Void. Convention date, Aug. 3, 1936. [Class 46] A filter element 4, Fig. 1, is formed of a metal band wound spirally, its inner end being attached to a sleeve 5, which slides on a central shaft 6, and its outer end attached to a fixed ring 2. The liquid enters the casing 8 through a connection 18 and passes upward through the element, filtrate being discharged through passages 21. Normally, the element aasumes a conical shape, as shown on the left of the Figure, a spring 7 forcing the sleeve 6 agninst a collar on the shaft. If the pressure below the element rises, the inner portion of the element is raised and the convolutions of the band rub against one another so as to detach collected impurities. If the pressure is sufficient to cause the element to assume the flat form shown on the right of the Figure, liquid can pass through an opening 14 into a hollow portion 15 of the shaft and thence to the outlet. The consequent reduction in pressure below the element allows the spring to force the sleeve down again into its original position. As shown in Fig. 3, two elements 27, 28, with their ends attached to a ring 25 and to sleeves 29, 30 are arranged about a horizontal shaft so that liquid supplied to the casing 24 through a connection 39 can litter through either element into the space between them which is in communication with a filtrate outlet 37. Rise of pressure causes the elements to move from the normal positions shown in the upper part of the Figure to the positions shown in the lower part, and allow liquid to pass through apertures 35 and 36 in the shaft to the outlet 37. On the consequent reduction of pressure outside the elements, a spring 32 returns the elements to their normal position. In a further modification, Fig. 4, the element is formed of metal band which is perforated so that liquid entering the element from both sides can collect in a channel 45 in the outer ring 47, which channel is in communication with the filtrate outlet 44. The sleeve 51 is reciprocated to detach impurities from the element by a crank 55 on a shaft 54 rotated by a pedal or the like 52 and a ratchet 53.

Abstract: 777,536. Starting fuel-injection engines. BOSCH GES., R. July 25, 1955 [July 29, 1954], No. 21393/55. Class 7 (3). [Also in Group XXVIII] A fuel injection pump comprises a piston 4 that operates in a closed cylinder 25 and is pressed by a spring 27 against a distributer member 3 of different diameter that is rotated and also reciprocated by a cam which engages stationary members. Suction takes place through ports 41 in the distributer which cooperate with a port 40 in the casing and the delivery is varied by an axially adjustable sleeve 21 which co-operates with a spill port 24. The fuel is delivered through a valve 17, which prevents drip at the injection nozzles, to a port 33 which connects to a number of outlets 34 in sequence. The piston 4 and cylinder 25 may be replaced by other units having pistons of different cross sectional areas. In the arrangement shown in Fig. 2, the sleeve 21 is fixed in an adjusted position by a pin 51 to give a maximum normal fuel delivery and a throttle valve 50 in the pump suction 40 varies the delivery within this range. To permit extra fuel for starting, the outlet 62 of the spill chamber 20 is closed by a valve 56 until the pressure of the feed pump 36 moves the valve against the spring 61.

Title: Device for the Programmed Recording of Data
Inventor: KUTSCHBACH ERNST
IPC: G06F3/06
Filed: 1967-05-10
Abstract: 1,187,780. Programmed data recording. BUCHUNGSMASCHINENWERK KARLMARX-STADT VEB. 10 May, 1967, No. 21658/67. Heading G4A. Recording of data on a first data carrier is controlled by a programme recorded on a second data carrier which may contain groups of instructions only and groups of instructions alternating with data, the groups being distinguished, and instructions having different parity from data. A change-over instruction occurs when a change from one type of group to the other type of group occurs, to reset two bistables set by arrival of instructions in the two types of groups respectively. Setting of the bi-stable for the instructions only groups switches a further bi-stable so that when the first data carrier is ready to receive data, the instruction is decoded to interrogate a matrix store in an office machine to supply data for recording, after coding, on the first carrier. Setting of the bi-stable for the instructions plus data groups (a) switches a further bistable to control a parity checker receiving the instructions and data from the second carrier, the parity for instructions being different from that for data as mentioned, and (b) allows a further bi-stable to be switched if the instruction agrees with one set up on the office machine. This last bi-stable then sets another to pass data from the second carrier to be recorded on the first, whereupon the recorder resets these last two bi-stables. The parity checker enables release of the office machine when its carriage is at a position specified by a stop instruction from the second data carrier, when such an instruction is present. Programme jumps dependent on the second data carrier and the office machine may be executed, but are not described in detail. Signs can be reversed prior to recording on the first carrier, under control of the second carrier and keys on the office machine. The second carrier can be copied straight on to the first, on actuation of a key. The second carrier is advanced step by step as the system is ready.
