Title: Improvements in or relating to condensation products from hydrocarbons or derivatives thereof and carbohydrate-like materials
Inventor: LINN CARL BARNES
IPC: C07C59/48
Filed: 1955-10-28
Abstract: Condensation products are obtained by reacting a carbohydrate or a desoxy or o -carboxy derivative of a simple sugar, in the presence of a Friedel-Crafts catalyst, with a non-olefinic aromatic or halo-aromatic hydrocarbon.  Temperatures are about - 40 DEG  to + 150 DEG  C.  Pressure may be atmospheric up to 100 atmos. or more, suitably the autogenous pressure generated.  Mononuclear aromatic hydrocarbons are generally preferred but those with two or more aryl groups or condensed benzene rings are utilizable. The halo-hydrocarbons specified include those containing one or more F, Cl, Br, and I atoms.  Carbohydrates include simple and compound sugars which are fully exemplified.  The catalyst may be a metal halide or BF3, preferably AlCl3, AlBr3 or BF3, alone or modified with an alcohol, ether, nitro-hydrocarbon or other solvent.  Hydrogen halide may be present as a promoter.  The products are analogous with those of Specification 787,531 and may be sulphonated, sulphated or nitrated to give detergents or explosives.  Other uses of the products are as surface coatings, for producing resins, as gelling agents, and plasticizers.  Thus, a reaction product of toluene and fructose gels benzene and pentane.  In examples: (1) toluene, d-glucose, and AlCl3 are reacted at 0 DEG  C. while passing HCl, the products comprising diaryl hydrocarbons and 1,1-di-(p-tolyl)-desoxy-D-glucitol; (2) d-glucose and benzene similarly yield 1,1-diphenyl-desoxy-D-glucitol; (3) chlorbenzene gives 1,1-di-(4-chlorphenyl)-desoxy-D-glucitol.

Filed: 1919-12-12
Abstract: 164,777. Denne, M. T. Dec. 12, 1919. Pulling-over.-In a machine in which the stretching is effected by power, means are provided whereby the stretching force applied to the upper may be gradually increased from zero to a maximum and gradually decreased to zero by actuation of a control means proportionally to the stretching force required. As shown, the extent of movement of a clutch pedal 77, Fig. 3, determines the pressure of friction discs 132, 133 on each other and therefore the thrust given to a last support, comprising a tread rest 105 and toesupport 103, connected by a link 114, bell-crank lever 116, gear-segment 135 and bevel pinion 134 with the driven friction disc 132. The edges of the upper are, during the upward thrust of the last support, held by grippers 190. An adjustable hook 250 may limit the descent of the clutch pedal to limit the stretching force to a predetermined maximum. A pawl 120, placed in or out of operation by a handle 123, may retain the last-support in any position to which it has been raised. This pawl is automatically put out of action when thrust is no longer required by a slide 126 operated from the main cam-shaft. Each gripper comprises a fixed jaw 5, Fig. 2, and a pivoted jaw 9 having a tail cooperating with a roller 15 on a lever 14 oscillated by a rod 17 normally pressed upwards by a spring 18 to keep the jaws closed. At the lower end of the rod 17 is a block 19 having a link 33 automatically operated from the main cam-shaft to open the grippers after the completion of stretching, and two lugs 21, 22 adapted to be operated by pedal. This pedal is connected by a link and lever and a chain 28. to a slide 26 normally raised by a spring 27 and provided with a lug 29 adapted to engage the lug 22 and a spring-pressed pawl 30 adapted to engage the tail of a hook 24 co-operating with the lug 21.

Abstract: 939,459. Surge diverters. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. Aug. 14, 1962, No. 31129/62. Class 38 (4). A magnetic blow-out arc gap device having preionising means comprises electrodes 14, 15 which are shaped and spaced to form an ignition gap 16 and a preionising gap 17 containing an insulating insert 18 maintained in contact with electrodes 14, 15 by springs 28, 29 acting thereon. The response voltage of the device is determined by the thickness of the member 18 which projects laterally beyond electrodes 14, 15, Fig. 3 (not shown). The electrode leads 19, 20 are crossed-over to obtain a magnetic blow-out effect and are separated by an insulating member 21. The device has a two-part insulating housing 22, 23 (Fig. 5) which forms an arc chamber 30 and vent 33, the inner walls of parts 22, 23 having interengaging zig-zag corrugations 39, 40 for increased arc quenching. Magnetic induction in the arc zone may be increased by providing a second housing of two soft iron parts 41, 42 insulated from the parts 22, 23 by shells 44, and slotted to prevent the passage of induced currents, Fig. 6 (not shown). The preionising gap may be formed in a plane at right angles to that shown in Fig. 2 by shaping the electrodes as shown in Fig. 9 and superimposing them with the insulating member positioned at the point 53 to provide the preionising gap, Figs. 7 and 8 (not shown). Fig. 11 shows another modification of the electrode arrangement of Fig. 2 in which the limbs 58, 59 of a V-shaped electrode are disposed one on each side of an insulating plate 57 which is positioned between the electrodes 60, 61 in such a way that the length of the arc path is approximately doubled. In Fig. 12 the insulating housing of the device carries segments 78, 79 of voltage control resistance material provided at their upper and lower sides (together with adjacent parts of the housing) with metallic cladding 80 which is connected to an electrode lead 88. The other lead 89 is connected to cladding 90 formed as a semi-circular annulus, the loops of metallic cladding increasing the magnetic blast effect on the arc. A number of arc gap devices as shown in Fig. 12 may be arranged in the bores of current limiting resistances to form an excess voltage diverter as for example in the manner shown in Fig. 14, where the device 93 is connected in series (under fault conditions) with resistances 91, 92 through supports 94, 95 whose contacts 97, 98 engage the metal cladding of the device, insulating members 96, 99, 100, 101 being provided. Rotation of contacts 97, 98 is prevented by slots (not shown) in the device housing.
