Title: Improvements in rotary machines for printing envelopes
IPC: B41F21/00
Filed: 1922-11-20
Abstract: 210,213. Post, C. L. Nov. 20, 1922. Rotary machines.-A machine for separating envelopes from a magazine, feeding them to a rotary printing-couple, and discharging them from the couple, comprises an adjustably mounted magazine M, Fig. 6, from which the envelopes are separated and fed to a printing-couple 21, 23 by an oscillating finger 12 which is moved across the bottom of the magazine to engage between the bottom flap and its envelope, the flaps normally projecting through an aperture in the bottom of the magazine. The finger 12 is carried by an arm 53 connected to a shaft 55, Fig. 4, which is oscillated by a cam 56, and the finger 12 is also given up- and-down movements about an axis at right angles to the axis of shaft 55 by a guide 59 which engages a roller on the arm 53. After the edge of the envelope has been forwarded by the finger 12, this finger is lowered to cause the flap to be engaged between a curved member 50, secured on the flat side of the D-shaped impression roller 23 and a corresponding segmental member 51 on the printing-roller 21. The feed of the envelope through the printing-couple is continued by adjustable rings 52 on the printing-roller which press the sides of the envelope against the blanket 47 on the impression roller. After being printed on, the flap of the envelope is pressed against the body to close the flap by means of a reciprocating rod 60 actuated by a cam 63. Inking-apparatus.-The printing-surface is inked by rollers 27, Fig. 1, mounted in journal boxes adjustable by screws 41. The rollers 27 are supplied by a roller 25 on which the ink is placed, and a distributing-roller 28. To make the supply of ink even, the roller 25 is reciprocated axially by a crank-pin on a disc 36, Fig. 4, driven by bevel gearing. The crank-pin engages a slot in a block 39 secured on the axle of the roller 25. Tripping-arrangements.-The shaft 22, Fig. 7. of the impression cylinder is mounted eccentrically in bearings fitted with a spring-controlled bail 81 which normally keeps the cylinder in printing position, and with an arm 82 which is rotated in a counterclockwise direction by a pin 89 mounted so as to be. slidable axially in a collar 87 carried by the printing roller. A bent arm 83 pivoted at 84 is adapted to move by gravity to the position shown in Fig. 7, when an envelope is not fed. This movement takes place when a lug 85 on a member 86 secured to the arm 83 enters a recess in the collar 87, and the member 86 then moves the pin 89 axially so as to cause it to act on the arm 82 to trip the impression cylinder. The pin 86 is returned automatically by a fixed cam.

Title: Improvements in or relating to change-over mechanism for liquid meters
IPC: G01F3/20
Filed: 1961-09-04
Abstract: 971,550. Liquid meters. KIENZLE APPARATE G.m.b.H. Sept. 4, 1961 [May 16, 1961], No. 31699/61. Heading F1A. A diaphragm type liquid meter has a valve slide 78 which is actuated by a rod 96 mounted in a pivoted stirrup 95. A switch-over lever 71 is connected to the stirrup 95 and is actuated by a rod 52 attached to a diaphragm 50 through a change-over mechanism. The lever 71 drives a counter 89 through a pawl 104, ratchet 106 and a gear train. Liquid enters through an aperture 100, causes the diaphragms 50, 111 to move outwardly expelling liquid from space 122, through a duct 123 into the space 120 and out through an aperture 102. The tumbler mechanism may be mounted above the diaphragm 50 (Fig. 1) or below (Fig. 2a). As shown in Fig. 2a upward movement of the rod 52 is transmitted to a slotted locking member 54 which pivots about an axis 55. A pin 63 abuts the lower end of the slot 57 in the member 54 thereby causing a rocking lever 64 to pivot about the axis 55 and an abutment 60 prevents the lever 71 operating the valve slide 78. A rod 65 pivots about the pin 63 and slides in a guide 68. When the rod 65 and lever 64 move beyond a position of axial alignment they snap upwards until the lever 64 contacts an abutment 81. The member 54 continues to pivot about the pin 55 until the abutment 60 slides off the arm 79 of the lever 71 which is freed to move the valve slide 78. Liquid then enters the space 120 and space 122 via the duct 123 moving the diaphragms 50, 112 towards each other and expelling the liquid therebetween through the aperture 102.

IPC: B44C5/00
Filed: 1964-08-05
Abstract: 1,106,377. Moulding plastic substances. L. B. O. TUGWELL. 2 Aug., 1965 [5 Aug., 1964], No. 31788/64. Heading B5A. [Also in Division B6] Decorative bodies are produced by forming a settable liquid mixture containing unsaturated polyester resin and water, casting, moulding or otherwise shaping the mixture to a desired form and allowing the mixture to set, the setting of the resin generating sufficient heat to evaporate the water and thereby cause internal cracks in the set shape. The water may be added as water per se, or included as a water content of another material e.g. a colouring material. There may be added to the resin in the liquid state an accelerator e.g. a cobalt accelerator colouring material, water and a hardener e.g. a peroxide hardener; and the mixture poured into a mould to set. The decorative bodies may be of any form, size or shape, solid or hollow e.g. panels or screens such as fire screens, windows, tiles, table tops, table lamp standards, paperweights, or bodies of block, rod, bar form for subsequent manufacture into articles. Colouring materials mentioned include Indian ink, a translucent resin pigment. The examples relate to a tile, a table top, and lamp standard manufactured from polyester resin.

Patent GB-740299-A (GB)
Title: Improved process for the preparation of enzyme extracts from liver and extracts so produced
IPC: C12N9/08
Filed: 1953-11-17
Abstract: Enzyme extracts (particularly catalase, cathepsin and arginase) are obtained from enzymebearing mammalian liver tissue by treating them with water to obtain an aqueous enzyme extract and bringing the pH of the latter to 5.0-5.6 to precipitate impurities.  The tissues may be extracted at pH 6.0-7.0 and the extract then acidified, or both steps may be carried out at 5.0-5.6.  Preferred conditions are pH 6.3-6.7 for the extraction and 5.2-5.4 for the precipitation.  The liver material may, before extraction, be washed at below 0 DEG  C. with an aqueous organic solvent (lower primary alcohol or acetone) at a concentration of 30-70 per cent.  Preferably 40-50 per cent ethanol is used at - 3 DEG  to - 15 DEG  C.  The purified enzyme extract after treatment at pH 5.0-5.6 is fractionally precipitated (below 0 DEG  C.) with 15-60 per cent ethanol or methanol at pH 4.2-7.4, the ionic strength being below 0.2.  Preferred conditions for this step are pH 5.4-6.2, ionic strength below 0.1, temperature - 3 DEG  to - 15 DEG  C. and alcohol concentration 20-50 per cent.  The amorphous precipitate so obtained (containing catalase and cathepsin) is dissolved in water at pH above 5.8 (preferably buffered) and the pH then reduced to 5.1-6.3 to crystallize the catalase.  Cathepsin can be obtained from the supernatant liquor.  Examples are given of the production of catalase and cathepsin from comminuted beef and hog liver tissues.

The board is marked with two sets of parallel tracks a, b for ordinary racing and steeplechasing respectively, and the tracks are divided into unequal numbers of spaces. The tracks are marked with starting lines e and winning posts f the inner track being also crossed by broken lines g to represent hedges, ditches or other obstacles. The central space h is provided with numbered sockets i into which may be inserted slips j coloured to correspond with the various model horses &c. used in the game. Groups of squares k, are used for scoring. For determining the moves of the horses over the tracks the device shown in Fig. 2 is employed. This device comprise a disc n rotatable on a base plate m by means of a knob o. The disc is divided into unequal sectors by radial lines p and is also marked with coloured arrow heads q. An arrow r on the disc indicates that a horse is out of the race. Around the disc are a number of removable and interchangeable devices s corresponding in colour to the various horses and each carrying two pairs of pointers t, u, the pair u being adjustable about pivots v. The rotation of the disc may be stopped by a spring-operated brake w retracted by a handle z. In using the spinning device, the number of sectors on the disc embraced by the pointers u of a particular horse when the disc is brought to rest determines the move of the horse. The arrow heads q are used in the steeplechasing game to indicate refusals and falls and co-operate to give such indications with the fixed pointer t.

Patent GB-618189-A (GB)
Title: Improvements in or relating to dehydrohalogenation processes
IPC: C07C1/30
Filed: 1946-10-31
Abstract: Alkynes containing at least four carbon atoms in the molecule are produced by heating dihalogen-alkanes and monohalogen-alkenes with an excess of an alkali metal alcoholate of an alcohol boiling above 100 DEG  C. dissolved in alcohol boiling above 100 DEG  C. and monohalogen-alkenes by heating dihalogen-alkanes with an equimolar quantity of the same although not necessarily anhydrous reagent. The dihalogen-alkanes and monohalogen-alkenes contain at least four carbon atoms, in the former halogen is attached to the same or adjacent carbon atoms and in the latter to an unsaturated carbon atom.  Chlorine and bromine as halogens and sodium and potassium alcoholates are preferred.  Preferred alcohols both as solvents and for alcoholate production are mono-alkyl ethers of glycols, e.g. mono-methyl and mono-ethyl ethers of ethylene and diethylene glycols others specified being amyl, isoamyl, hexyl and isohexyl alcohols, ethylene and propylene glycols and mono- and di-methyl or ethyl ethers of glycerol.  The reaction with dihalogen-alkanes takes place in two stages, the first stage resulting in the elimination of one molecule of hydrogen halide to give a mixture of isomeric mono-halogen-alkenes which are then converted under preferably anhydrous conditions to alkynes by the removal of another molecule of hydrogen halide.  Thus, in the first stage a mixture containing 2-chloroalkenes-1 and cis-and trans-1-chloroalkenes-1 is obtained from 1,2-dichloroalkanes.  It is stated that butyne-1 is obtained from 1,1-dichlorobutane, 1,2-dibromobutane or 1 - bromobutene - 1; pentyne - 2 from 2,3-dibromopentane or 3-chloropentene-2; hexyne-2 from 2,3-dichlorohexane or 3-bromohexene-2; heptyne-3 from 3,4-dibromoheptane or 4-bromoheptane-3; heptyne-1 from 1,2-dibromoheptane, 1,1-dichloroheptane, 1 - bromo - heptene - 1 or 2 - chloroheptene - 1; hexyne - 1 from 1,2-dibromohexane or 1-bromohexene-1 and bromohexene-1 from 1,2-dibromohexane.  The anhydrous alcoholate is prepared by dissolving an alkali metal hydroxide in an alcohol, heating and removing water by an azeotropic distillation with, e.g. benzene, toluene or xylene, or by dissolving the free metal in the alcohol.  In each example, ethylene glycol mono-ethyl ether is used as a solvent and hexynes, hexyne-1 preponderating, are produced in (1) and (3) by treating mixed 1- and 2-chlorohexene-1 (obtained by heating 1,2-dichlorohexane with potassium hydroxide dissolved in ethylene glycol monoethyl ether) or dry 2-chlorohexene-1 with anhydrous sodium or potassium alcoholates of ethylene glycol mono-ethyl ether and in (2) from dry 1,2-dichlorohexane and the anhydrous potassium alcoholate of ethylene glycol mono-ethyl ether, in (4) heptynes, heptyne-1 is mentioned, are obtained by treating mixed monochloroheptenes, obtained by heating 1,2-dichloroheptane with sodium hydroxide dissolved in ethylene glycol mono-ethyl ether, with the sodium alcoholate of ethylene glycol mono-ethyl ether.
