Title: Improvements in coin-freed vending apparatus
IPC: G07F11/06
Filed: 1934-01-31
Abstract: 414,302. Coin-freed article-delivery apparatus. HEILAND, A., Rangsdorf, Berlin. Jan. 31, 1934, No. 3290. [Class 27.] In a coin-freed vending-machine wherein a column of trays is supported so that the bottom tray may be released so as to descend and rock into an inclined position to deliver an article thereon, the trays are provided with lugs engaging in channel guides. As shown, trays 3, Figs. 2 and 3, supported on brackets 5 on a pair of slides 6, are provided with lugs 4 engaging in posts 1, 2, the bottom tray when released falling on to brackets 10, 11 where it is held inclined to deliver an article on to a shelf 12. The trays have notches 9 placed differently in alternate trays so that when the notches of the bottom tray are in register with the brackets 5 to release the said tray, the tray above will be supported until the next operation of the slides. These slides, inter-connected by a rod 8, Fig. 4, are reciprocated by a draw-bar 13 which is normally locked by a pawl 14 and released by a suitable coin-operated device. When the bar 13 is withdrawn with the slides 6 in the position shown in Fig. 4, a lever 16 on the bar is tilted by an abutment 17 thereon engaging a stop 20 on a latch 19 on one of the slides and engages the arm 15B of a lever 15, Fig. 5, connected by a pin 23 to the slide, to move the slide to the position shown in Fig. 6, the bar being retracted by a spring. On the next withdrawal of the bar 13, the lever 16, tilted by gravity, engages the arm 15<A> and returns the slide to the position shown in Fig. 4.

Title: Improvements in washing systems for milking equipment
Inventor: KINGSTON JONAS ARTHUR
Filed: 1951-02-10
Abstract: 696,507. Washing teat cups. GASCOIGNES (READING), Ltd. Feb. 11, 1952 [Feb. 10, 1951], No. 3309/51. Class 138 (i). [Also in Group XXVIII] Washing equipment for the teat-cup cluster and associated parts of a pneumatically-operated milking machine comprises a teat cup immersion vessel 13, a washing liquid reservoir 1 adapted to discharge liquid into the vessel 13, a shut-off valve 12 for regulating the discharge of liquid from the reservoir into the vessel, a teat-cup cluster 2 connected in circuit with the reservoir and adapted when the mouths of the teat-cups are below the liquid level in the vessel to complete a closed liquid circuit, the arrangement being such that the application of suction to the reservoir 1 causes the valve 12 to close and liquid to flow up through the teat cups into the reservoir until the suction therein is broken by reason of the liquid level dropping below the mouths of the teat-cups, whereupon the liquid accumulated in the reservoir opens the valve 12 to empty liquid into the vessel and thus restart the intermittent flow cycle of the liquid. The cluster 2 is connected by its associated tubing 3 to the reservoir 1, normally constituting the milk receiver of the milking machine and suspended from a weighing instrument 4. The reservoir is connected by a tube 5 and tap 7 to a vacuum line 6 and when the tap is in a position for disconnecting the tube 5 from the line 6 it allows air to enter the tube through a vent (not shown). The usual valve controlled tube for normally leading milk from the reservoir to a churn is replaced by a discharge pipe 10 provided with the valve 12 which is a flap valve normally spring urged to a closed position. The vessel 13 is divided by a partition 14 into chambers 15 and 16 interconnected by a siphon 17. When suction is applied to the reservoir the valve 12 is retained closed and liquid is drawn up through the teat cups from the chamber 15 until the suction is broken by the falling level therein. Liquid is then discharged from the reservoir into the chamber 16 and when the level therein reaches the bend of the siphon it is carried over itno the chamber 15. As soon as the cups are re-immersed in liquid the cycle recommences. Instead of the flap valve a piece of thinwalled rubber tubing may be provided which collapses to close when its interior is under suction.

IPC: D04H1/54
Filed: 1944-02-24
Abstract: 582,006. Fibrous batting. BRITISH CELAN ESE, Ltd., (Celanese Corporation of America). Feb. 24, 1944, No. 3452. [Class 140] A self-supporting batting is prepared by forming a skin on both sides of a sheet or layer of interlaced and matted staple fibres of which a substantial proportion are thermoplastic, by rendering adhesive the thermoplastic fibres at or near the surfaces so that the fibres there stick to one another. The thermoplastic fibres are rendered adhesive either by the application of heat and pressure or by the application of a solvent or softening liquid or by both methods in conjunction. The thermoplastic fibres are preferably of cellulose acetate but other substances such as cellulose esters, mixed esters, cellulose ethers, synthetic linear polyamide condensation products, polymeric vinyl halides or vinyl esters of organic acids or their copolymers and polymerized methacrylic acid esters may be used. Non-thermoplastic fibres of cotton, silk, wool, regenerated cellulose, jute, hemp and like materials may be added but preferably constitute only 20 per cent. or less of the total fibre although up to 75 per cent. may be used. Local application of heat and pressure to the batting may be given for a quilted effect rendering small areas of the fibres adhesive throughout the thickness and uniting the two skins. The apparatus comprises a blower 12 which draws the fibres through an intake port 17 and discharges the separated fibres as a loose whirling mass within the chamber 16. The fibres are consolidated on a moving foraminous belt 18 by the suction of air drawn through perforations 21 in a chamber 20 which is connected to a vacuum pump. The belt is driven by toothed rollers 24, 26 mounted in adjustable shafts and connected to a suitable source of power, the speed of the belt determining the thickness of the batting. A doctor blade 32 directs the batting to a guide member 33 and to heated rolls 34, 35 which are surfaced with paper, fabric or plastic material to prevent sticking. Alternatively, belts or blankets may pass between the rolls and the batting. The time of contact with the heated rolls, their temperatures and the proportion of thermoplastic fibres determine the thickness of the skin which is formed. In another form of the apparatus, (not shown), a doffer beater opens up the staple fibres and throws them into a chamber and on to the moving conveyer belt through which air is drawn by suction. The belt passes the batting between two heated calendar rolls each of which carries an endless blanket passing over other idler rollers to prevent the batting sticking to the heated rolls. The batting then passes on to another conveyer belt and to an impact moulding device in which it is subjected to pressure from hot projections to give it a quilted form.

Title: Processes for preparing tetrazoles
IPC: C07D257/06
Filed: 1928-02-03
Abstract: 285,080. Boehringer, A., (trading as Boehringer Sohn, C. H.). Feb. 11, 1927, [Convention date]. Addition to 280,529. Samples furnished. Tetrazoles.-C-Amino-tetrazoles are obtained by treating esters of amidoximes, particularly the sulphonic esters or so-called Beckmann transformation products thereof, with azides or free hydrazoic acid: or by treating the amidoximes in the presence of hydrazoic acid with substances, such as thionvl chloride and phosphorus oxy- or penta-chloride, which form esters with the amidoximes, the esters then undergoing the Beckmann transformation. The reaction takes place with at least an equimolecular proportion of the azide and in the presence of water or an organic solvent, to which a basic substance may be added. According to the examples, (1) 1-benzyl-5-amino 1:2:3:4- tetrazole is produced by esterifying phenylaceticamidoxime with benzenesulphonic acid and heating the product with alcoholic sodium azide, (2) 1-phenyl-5-amino-1:2:3:4-tetrazole results when benzenyl-amidoxime is first esterified with benzenesulphonic chloride in caustic soda solution and the ester then boiled with alcoholic sodium azide. The Specification as open to infection under Sect. 91 (3) (a) states also that ethers of C-oxvtetrazoles are obtained in the same way from hydroxamic acid esters. This subject-matter does not appear in the Specification as accepted.

Abstract: 796,438. Treating sewage and waste effluents. NEDERLANDSE ORGANISATIE VOOR TOEGEPASTNATUURWETENSCHAPPELIJK ONDERZOEK TEN BEHOEVE VAN DE VOLKSGEZONDHEID. Feb. 3, 1956 [Feb. 7, 1955], No. 3492/56. Class 111. Sewage or the like is supplied at 3 through a sieve 4 to a ring-shaped reservoir 1, Fig. 1, and circulated in the direction of the arrow, and at the same time aerated, by a rotating brush 2. Purified effluent is discharged to open surface water 5. When sewage is supplied discontinuously, openings 11 in a dam wall 6, Fig. 2, are provided, allowing so much water to pass through continuously that no water is discharged over the upper edge of the dam on introducing a fresh charge of sewage into the circuit. The rotating brush 2 may be stopped during such introduction to prevent the discharge of unpurified sewage. An automatic switch device may be provided which periodically stops the rotating brush so that sludge is deposited, subsequently effects discharge of a certain quantity of purified effluent, and then effects supply of an equal quantity of sewage. The last two steps may be modified in that the switch device effects the supply of sewage, by which an equal quantity of purified effluent is discharged. The sludge has a mineral content of at least 30 per cent. Preferably the oxygen content (free and as nitrate) of the mixture in the apparatus is maintained at not less than 3 mg per litre, the sludge (both supplied and formed) is substantially decomposed in a detention time of at least 40 hours, and the BOD (5) reduction is from 90 to 95 per cent. The surface dimensions of the apparatus are such that at least three inhabitant-equivalents of sewage are treated per square metre per day and the capacity is not less than one-and-a-half times the daily supply of sewage.

Title: Improvements in printer format control system
IPC: G06K15/06
Filed: 1958-02-04
Abstract: 849,026. Selective printing. GENERAL ELECTRIC CO. Feb. 4, 1958 [Feb. 5, 1957], No. 3602/58. Class 100(4). An output printer associated with e.g. a statistical machine has a format control system comprising a plurality of storage registers 40, 42, 44, each of which is assigned to hold items for printing at different portions of a line so that data received from a source 20 read from a magnetic tape or drum can be printed on a sheet in specified positions. As shown in Fig. 1 data on a magnetic tape comprises different items e.g. name, debit, credit, and item count, each being preceded by an identifying code #, -, +, and I respectively and these codes determine the position the data is printed on a sheet Fig. 2 by the effect of that identifying code on a symbol senser 22 and the control system. In printing out the information it can be arranged that certain format rules are complied with viz. the name shall occupy a line on its own, there shall not be more than two debits on one line, there shall not be more than three items per line, there shall not be more than one credit per line, and that there shall be only one item count on a line. The recognised identifying code is applied by the symbol senser 22 to a data routing circuit 24 and to a format-matrix control 26 which has relays that establish predetermined connections in a format matrix 28 to partly control operation of the output printer in a manner which complies with the printing format shown in Fig. 2. The manner of printing is also controlled by the data routing circuit 24 in conjunction with the input signals. The output from 24 is applied to AND gates 30, 32, 34, the particular opened gate, applying data to one of the registers 40, 42, 44, and these allocate the data to the beginning, middle or the end of a line. The printer is of the kind having a rotating cylinder which has type columns on its periphery, and a series of hammers actuated by solenoids when a particular character is in printing position. The position of the characters on the cylinder is identified by information on the type drum itself or an auxiliary code wheel device 48, and this is connected to a comparator 50 so that printing of correct characters occurs. Specifications 767,431 and 769,908 are referred to.
