Title: Improvements in or relating to carton or box making machines
IPC: B31B3/00
Filed: 1945-06-11
Abstract: 596,410. Making cartons. CHALMERS, J. W., and MOLINS MACHINE CO., Ltd. June 11, 1945, No. 14724. [Class 18] A machine for making cartons from blanks, such as are shown in Fig. 7, comprises means for applying adhesive to appropriate parts of a blank, mechanism for bending flaps connected to the bottom body panel at right angles to the panel b, so that they contact the applied adhesive, and mechanism for bending the bottom body panel at right angles to the back panel of the box, and guides or like devices for co-operating in the bending of the flaps to guide them inside the side panels of the box when the bottom panel is bent up. The adhesive may be applied either to the inside surfaces of the side panels c' or to the bottom panels b, in which case the flaps b<1> are hingedly secured to the side panels c'. The adhesive is supplied to the blank by wheels revolving in a bath 700. The invention is described in connection with the machine set out in Specification 508,466. In this machine the vertical side walls of the conveyer pockets 224, Fig. 4a, are modified to form short guiding extensions 708, so that when the blank is engaged by the plunger base plate 257, the flaps b<1> are turned up vertically with the panels c<1>. The panel b is then turned up vertically by an extension 709 of the folder 263. This action also tends to turn up panel a, but is checked by a rail 710 having an upturned end near the folder, which holds the panel a down so that the blank can pass beneath other parts of the machine. A small folder turns the panel a to its final position on the top of the inner member, and the remaining operations are as described in Specification 508,466. In a modification, Fig. 18, the guiding device for bending the flaps b' when the bottom panel b is turned up vertically consists of two plates 711 fixed to a rod 712 and reciprocated by a cam 713 geared to the conveyer drive. Specification 596,407 also is referred to.

Title: Treatment of diene elastomers with boron comopunds
Inventor: PAMPUS GOTTFRIED
IPC: C08C19/00
Filed: 1966-04-04
Abstract: The properties of diene elastomers e.g. cold-flow, are improved by heating a solution or dispersion of a diene elastomer in a liquid medium at temperatures of 10 DEG  to 170 DEG  C. while in contact with a compound containing at least one boron-hydrogen bond.  The boron compounds may have the formula BnHn + 4 or Bn\Hn + 6 in which n is 2 to 10, and are preferably addition products of boranes with amines. The diene polymers are suitably butadiene, isoprene, piperylene, and chloroprene polymers, and copolymers of these dienes with vinyl or vinylidene compounds e.g. styrene and acrylonitrile. Suitable solvents or dispersing agents are aromatic and aliphatic hydrocarbons and chlorohydrocarbons, and also, as the continuous dispersion phase, water, in which case the elastomers may be first dissolved in an organic solvent, and the solution dispersed in the aqueous phase. In the examples, (1) polybutadiene, prepared using TiCl4/I2/AlR3, in which R is an alkyl group, is treated with (C2H5)3N: BH3 in toluene; (2) polybutadiene, prepared using (C4H9O)TiT3/Al(i-C4H9)3, is treated with (C2H5)2NH: BH3 in benzene; and (3) polybutadiene, prepared as in (2), is treated with (C4\H3)3\N : BH3 in benzene.

Patent GB-488748-A (GB)
Title: An emergency brake for automobile vehicles
IPC: B60T1/14
Filed: 1937-05-29
Abstract: 488,748. Vehicle skid brakes. MENNET, G., AQUILLON, J. D., and AQUILLON, J. May 29, 1937, No. 14988. Convention date, May 29, 1936. [Class 103 (i)] In an emergency brake for motor vehicles comprising brake shoes carried by pivoted arms whereby they may be lowered to engage the track and raise the vehicle to a limited extent, the shoes are held in the raised position by a cable wound on a drum which can be released by a lever to permit the shoes to fall, further movement of the lever closing the circuit of a motor and engaging gearing to drive the drum for returning the shoes. Automatic breaking of the motor circuit and disengagement of the gearing is effected. Brake shoes 1 shaped as shown to permit engagement with the track are adjustably secured to arms 3 pivoted at 4, the arms having abutments 8 for engagement with a stop 9 on the wheel axle to limit the rearward movement of the arms and shoes. The arms of a number of shoes may be connected by a cross-bar 7. A cable 14 extends from the bar 7 to a drum 18 mounted in a casing 19. Rotation of the drum with the shoes in the raised position is prevented by the engagement with a notch in a disc 34 secured to the drum of a projection 33 on a lever 30. A lever 31 mounted on trunnions has a hollow part in which is mounted a worm 45 adapted to engage a worm-wheel 35 secured to the drum. A shaft 65 is connected by a cardan-joint to the worm shaft 53 and is geared by toothed wheels 63, 64 to an electric motor 62, Fig. 1. The lever 31 is normally locked in the position in which the worm is disengaged by a detent 48 on a lever 47 pivoted at 44 and held in position by the engagement of its end with a pin 46 on the lever 30. A lever 24 secured to the shaft 27 of a hand lever 23 has slotted link connections 25, 26 with the levers 30, 31. Movement of the lever 23 to the right from the position shown moves the lever 30 to unlock the drum and permit the shoes 1 to fall into engagement with the track. The detent. 48 is also disengaged from lever 31. To raise the shoes, the hand lever 23 is moved to the left, thus moving lever 31 to engage the worm, Fig. 6, and to close a switch for the motor so that the drum winds up the cable until the projection 33 on lever 30 re-engages the notch in disc 34 under the action of a spring 49. This movement of the lever 30 disengages through a link 41 a detent 42 pivoted at 44 thus permitting the return of the lever 31 to disengaged position under the action of a spring 58, the motor circuit being broken at the same time. After the lever has been moved to the left it is returned to the normal position to permit the subsequent return of the lever 31.

Title: Improved process for producing town gas with low content of carbon monoxide
IPC: C01B3/48
Filed: 1962-04-19
Abstract: In a process for producing a combustible gas, suitable for use as town gas, having a calorific value of at least 3000 K.cal./Nm3 and not containing more than 5% Co from gaseous or liquid hydrocarbons, the hydrocarbon mixed with steam or a steam and air mixture in an amount sufficient for the entire process is passed at a temperature between 600 and 1000 DEG  C. over a polyfunctional catalyst to gasify the hydrocarbon partially and the resultant gas mixture is cooled by heat-exchange with process steam to a temperature not below 350 DEG C. and led successively over a hydrogenating catalyst and a shift-reaction catalyst to produce the gas required, heat-exchangers being provided between the various stages to superheat the steam such that no further heat need be supplied to the process.  The steam-to-hydrocarbons weight ratio may be between 1.5 to 1 and 3 to 1 and the steam before being mixed with the hydrocarbons may be superheated to between 300 DEG  and 600 DEG  C. The poly-functional catalyst in the first stage promotes cracking and gasification of the hydrocarbon and the partial shift-conversion of CO. The first stage is preferably conducted at a temperature between 650 DEG  and 850 DEG C. and the second and third stages at temperatures between 430 DEG and 470 DEG  C. and 370 DEG  and 450 DEG  C. respectively.  When a very low CO-content is required, e.g. about 1%, a second shift-reaction stage at a temperature between 300 DEG  and 400 DEG C. and a reduced space velocity, may be included. Catalysts suitable for each stage are listed and apparatus for carrying out the process is described.  The hydrocarbon constituting the starting material may be subjected to a preliminary hydrogenating treatment to reduce the weight ratio C/H to 5.5 or less.  Alternatively the hydrocarbon may be fractionated to produce a head product having a weight ratio C/H of not more than 5.5.  Specification 980,259 is referred
