Title: Bagging Apparatus
Inventor: MILLS JAMES CLAIBORNE
IPC: B65B5/04
Filed: 1967-03-03
Abstract: 1,188,351. Packaging articles in bags; endless conveyers. AMERICAN MACHINE & FOUNDRY CO. 4 March, 1968 [3 March, 1967; 7 June, 1967], Nos. 10201/67 and 26296/67. Headings B8A and B8C. Articlos received from an infeed conveyer 72 (Fig. 11) are supported and positioned for delivery to a bagging mechanism reciprocated across the end of the conveyer and of an outfeed conveyer 40, to which bagged articles are carried after removal from the bagging mechanism. The machine illustrated is a modification of that described in Specification 1,088,222. The support consists of a reciprocating plate 280 (shown in plan in Fig. 9), drawn rapidly from beneath the article, e.g. sheets, pillow cases &c., to position and retain it against a fixed adjustable comb 276 before it falls on to the bagging mechanism. The mechanism has scoops 124, 128 (Fig. 6), designed to pass around a stop 290 (Fig. 11) as it moves below plate 280, the scoops moving together to enter a plastics bag and quickly separating to grip the inside of the bag. As they recede, the stop 290 engages the end of the article, preventing it from receding with the carrier, and pushes it between the scoops into the bag. The stop is spring- loaded so that an arm (292), (Fig. 2, not shown) breaks a beam of a photo-cell (297) to stop the machine if the stop jams in the package. Ribs (298), (Fig. 4, not shown), projecting from the scoops facilitate the removal of the package which is finally pushed off the ends of the scoops to fall on to a set of tines 38. These pivot downwardly to pass between the slats (356), (Fig. 1, not shown), endless belts (354) engaging and taking the package away.

[Class 81 (ii)] [Also in Group XIV] In apparatus for administering intestinal baths, the flushing head piece 1 is provided with a removable rubber pad 4 in which is embedded, e.g. by vulcanization, a shaped plate which prevents deformation and ensures a tight fit between the head piece and the anal region of the patient. Further assistance is given by a thick weighted rubber pad 6. The carrying cables K for the head piece are preferably adjustable in length, and the rear carrier is provided with a soft rubber cushion 21. The excrement discharge tube 12 is provided with stiffening ribs 13 or with a helical wire insert. The foot-supporting ladder 15 is provided with weighted rungs covered with sheet rubber to prevent undue movement thereof. The rectal tube 8 is connected to the supply pipe by a moulded rubber knee piece 9, Fig. 4, to prevent irritation of the colon by undue rigidity, being held in position by suitable beading, and may be made of rubber, preferably with a helical wire insert. Blockage of the exit of the rectal tube is prevented by a suitable wire basket. A metal tube may also be used, part of which consists of a closely wound wire spiral. Fig. 5 shows a rectal tube provided with a conical valve 11 outside the rectum so that on contraction of the sphincter muscle, flushing water entrapped in the rectum is released by the lifting of tube 8, from its seating. The flushing operation is controlled by a three-way cock 22 affixed to the side of the bath, e.g. by a suction disc. By diversion of the water supply to a branch pipe 25 connected to the bottom of the outlet column 26, the discharge of the flushing water from the colon is increased by syphon action. A glass indicating vessel 28 is interposed in the supply pipe for the flushing water. Fig. 9 shows suitable forms having flat parallel front and back walls. The back wall is coloured and provided with a radial scale 30 to indicate the rate of flow of the water, while a vertical scale 31 indicating the water level shows the static pressure set up in the colon.

Patent GB-848470-A (GB)
Title: Improvements in or relating to basic chromic chlorides
IPC: C01G37/04
Filed: 1957-08-21
Abstract: Soluble basic chromic chlorides are prepared by reducing an aqueous solution of a hexavalent chromium compound with an organic reducing agent, in an amount at least sufficient to reduce all the hexavalent chromium, in which the reducing agent is added in two portions, the first being insufficient to cause the solution to gel, and the remainder being added with hydrochloric acid; the amount of hydrochloric acid added never exceeds the stoichiometric amount required to form chromic chloride.  The greater the desired degree of basicity of the product, the less hydrochloric acid employed.  The amount of reducing agent originally added is preferably less than 66% of that required to reduce the hexavalent chromium to trivalent chromium.  Suitable organic reducing agents are monoand polysaccherides, such as glucose, and some polyhydroxy compounds such as glycerine.  Suitable hexavalent chromium compounds are chromic acid and alkali-metal bichromates. The solution of basic chromic chloride may be dried by spray-drying.  The basic chromic chloride thus obtained is soluble in water and organic solvents, including methanol, ethanol, isopropanol, and acetone.  If sodium bichromate is employed as a starting material, sodium chloride can be eliminated from the product by concentrating the solution of basic chromic chloride formed, and adding acetone to precipitate the sodium chloride.

Inventor: MASSONNE JOACHIM
IPC: C07C17/10
Filed: 1965-06-23
Abstract: In the bromination of fluoro- and fluorochloro-hydrocarbons the reaction gases are treated to recover bromine from the hydrogen bromide formed by treating the reaction mixture at a temperature of 250-500 DEG  C. with oxygen or free-oxygen containing gases in the presence of an oxidation catalyst composed of a porous carrier steeped with salts of a metal, the gases leaving the catalyst are cooled to room temperature and passed through a selective bromine solvent and the bromine recovered by cooling and dissolution.  The catalyst may be an aluminium oxide carrier steeped with copper, rare-earths and/or alkali metals as the chlorides.  The catalyst may be activated at 450 DEG  C. 5-20% stoichiometric excess of oxygen may be used.  After oxidation the gases may be cooled to room temperature and the bromine separated. The gases may also be scrubbed with a solvent selective for bromine, e.g. dibromo-ethane, tetrabromo-ethane, bromo-benzene or alkali bromine solutions.  The bromine may be recycled.ALSO:In the bromination of fluoro- and fluoro-chloro-hydrocarbons the reaction gases are treated to recover bromine from the hydrogen bromide formed by treating the reaction mixture at a temperature of 250-500 DEG  C. with oxygen or free-oxygen containing gases in the presence of an oxidation catalyst composed of a porous carrier steeped with salts of a metal, the gases leaving the catalyst are cooled to room temperature and passed through a selective bromine solvent and the bromine recovered by cooling and dissolution.

Electric plant.-In lift systems of the kind provided with an auxiliary electric motor for bringing the lifts accurately and automatically to rest level with a floor, the auxiliary motor is used automatically to vary the effective length of the winding rope through auxiliary apparatus independently of the main winding drum and hoisting mechanism. In one construction the winding ropes 3, 4, Fig. 3, pass round stationary sheaves 5, 6 and over travelling sheaves 7, 8 to a winding drum 9. The sheaves 7, 8 are moved independently in directions to cause the lifts to approach the floors by small electric motors 10, Fig. 6, which drive screws 14 engaging travelling nuts attached to the bearings 12 in which the sheaves are mounted. These motors are switched in after the main hoisting motor has been cut out and are de-energized when the lifts reach the floor. They are again switched in and reversed if the lifts overrun the floors. The sheaves 7, 8 may be connected in such a way that they move in opposite directions and are actuated by a single motor. In another construction the winding rope passes from the main drum 9, Fig. 9, under a sheave 36 attached to the lift 37, and then back to a small auxiliary drum 38 driven by an auxiliary motor 10. In a further construction the auxiliary drum and motor are mounted on the lift.

Title: Improvements in or relating to beam-indexing picture display systems
Inventor: RUDD DENNIS ARTHUR
IPC: H04N9/24
Filed: 1959-08-05
Abstract: 897,982. Television. MULLARD Ltd. May 9, 1960 [Aug. 5, 1959], No. 26750/59. Class 40(3). In a colour television receiver utilizing a beam indexing technique at least two partial indexing signals which are all of the same frequency but phase displaced by equal amounts are produced. These are first brought into phase and then combined to form a single final indexing signal which is employed to control the application of colour signals to the (single) gun of the colour picture reproducing tube. With this arrangement the variation of the phase of the final indexing signal with variation in amplitude of the colour signals is much less than that produced in any of the partial indexing signals. The indexing stripes may consist of some or all of the colour triplet stripes themselves (Fig. 5) or, separate conductive indexing stripes may be associated with each of the former (Fig. 7). Alternatively, some of the colour stripes together with additional stripes producing U.V. light may be utilized for the production of the indexing signals. This latter arrangement is shown in Fig. 8 where the additional stripes U replace the "guard bands" between the red and green stripes. The direction of line scanning may be at right angles to the length of the stripes or parallel thereto with the addition of "spot wobble" by means of a saw-tooth wave. If the received signal is of the N.T.S.C. type this must first be converted (e.g. using a "Y" to "M" converter) into a form suitable for sequential display. Specifications 897,983 and 987,984 are referred to.

In a multi-page rotary printing press having a fountain roller 2, Fig. 2, an ink-retaining chamber is defined by the fountain roller 2, scraper blade assembly sections 13 and end plates 11 and the ink chamber is divided into a plurality of fluid-tight compartments A, B, C, D, Fig. 1a (Fig. 1b not shown), by a central divider 8 and sector dividers 12. Each compartment is provided with an individual scraper blade holder 23 supporting a scraper blade 14 and the holder is slidable in grooves 22 in the dividers to urge the scraper blade 14 into ink-sealed engagement with the clockwise rotatable fountain roller 2. Lock devices 15 are mounted on the sides of the dividers and end plates to secure the scraper holders 23 against surfaces 22a, 22b by operation of the handle 37. Each of the compartments receives ink from the main conduit 19 through individual outlet channels 40. The ink supply is regulated by a valve stem 34, mounted in the dividers, the valve stem being rotatable by a hand grip 35 and the ink enters the channel 40, Fig. 5, from the conduit 19 by a passageway 32 formed in one end of the stem 34 by removal of one-half of the end portion from shoulder 33. The amount of ink transferred by the fountain roller 2 is controlled by setting of a fountain blade 25 flexed by action of a fulcrum 27 through a blade control mechanism 26. When a page is to be blanked-off the associated scraper assembly 13 is moved out of contact with the fountain roller 2 and the ink drained into a trough 16, which collects also the ink overflowing from the compartments, the ink being filtered through a screen 28 before being drained through a pipe 17 and pumped back into the main conduit 19. In another embodiment in Fig. 7, the main conduit 19 may be positioned outside and well below the ink compartment. The outlet channel 40 is replaced by swivel feed spigot 42 terminating in a pipe 46. The ink supply is regulated by a valve 48 having a cylindrical gate 49. with removal section 50
