IPC: F28C3/04
Filed: 1967-11-28
Abstract: 1,155,338. Heat exchangers. GEBR. BOHLER & CO. A.G. 29 Nov., 1967 [29 Nov., 1966], No. 54313/67. Headings F4K and F4S. A heat exchanger comprises an external pipe 5 reinforced with an inner, slit pipe 11 and a concentric and radially-spaced inner pipe 1 through which a hotter medium is conveyed to a mixing chamber 3 to which the cooler medium is admitted from an inlet 2 in the pipe 5. The mixture passes to an outlet 4 in countercurrent flow to the hotter medium over the outer surface of the pipe 1 which forms a thermally conductive wall. The wall is formed by at least two concentric pipes, each of which having a slit to absorb thermal expansion which may be longitudinal or helical and so positioned as to be out of register with each other. A coil spring 10 retains the sleeve 11 in the region of the outlet zone 9 of the mixing chamber 3 to protect the external pipe 5 from localized thermal shocks from the mixing process.

Title: Tubular pile driving system - has shoe forming annular internal and external chambers for filling with hardening material
IPC: E02D5/72
Filed: 1975-08-11
Abstract: The pile consists of a tube driven into the ground and enclosed in a hardened mass of filler material. An annular shoe is fitted to the bottom of the shoe, so that on driving the pile a chamber is formed for the material, which is delivered in the liquid state. The shoe (212) also protrudes radially on the inside of the tube (211), thus forming a further annular chamber (112) on the inside between the tube and the earth (11'), which is likewise filled with the hardening material. The latter can be delivered through pipes (213, 214) extending to points close to the shoe inside and outside the tube, or to one side only, holes being provided in the tube near the shoe through which it flows to the other side.

Abstract: The novel medicaments contain 5-fluoronicotinate esters of formula (I) and/or their salts (where R is Et, i-Pr, cyclohexyl, 3-pyridylmethyl, 2-(5-fluoronicotinyloxy)ethyl or 2-nicotinyloxyethyl). The cpds. give a 98-125% decrease in noradrenaline-induced free fatty acid levels at an oral dose of 100-200 mg (dog). The hypolipaemic effect is maintained at >=50% of this value for 100-170 min. or more. The toxicity of cpds. (I) is low (1-2 g/kg i.p.). In an example, a mixt. of 43.6 g 5-fluoronicotinic acid and 550 ml SOCl2 was refluxed for 4 hrs., the excess SO-Cl2 distd. off, and the residue slowly treated with 420 ml abs. EtOH at room temp. The mixt. was refluxed for 2.5 hrs., the excess EtOH distd. off, and the residue treated with excess NaHCO3 soln. and extracted with ether. The extract was dried, evapd. and distd. to give 40.9 g of (I; R=Et), b.p. 92-94 degrees C/13 mm Hg.

Patent NL-8001561-A (NL)
Title: Semiconductor etching preparation method - uses second UV exposure and thermal hardening to reduce blurring
IPC: G03F7/20
Filed: 1980-03-17
Abstract: When semiconductors are made by etching a substrate (1) through a film mask (2,6) the unwanted areas (5) of the mask are first removed by alkaline development after ultra-violet exposure (4). One problem with this method is that the etching agent also damages the edges of the mask resulting in poor definition or blurring. A second exposure to ultra-violet rays, with a wavelength of 330 to 450 nm, gives the remaining mask fine times the resistance to etching of a mask which has not received this second exposure. The substrate and mask are then put into a 125 deg.C. infra-red oven, for 5 minutes to provide further hardening of the film.

Title: Guy rope partic. for grounded metal mast - is of synthetic fibre with end potted in connector with corona discharge element
IPC: E04H12/20
Filed: 1981-06-10
Abstract: A rope is of dielectric synthetic fibre, pref. aromatic polyamide, with a terminal at one end for connection to the structure and including a head in which splayed fibres are encapsulated in potting material to attach the terminal to the rope. A corona discharge element is attached to the head and located annularly around the rope where it enters the head to minimise the danger of a discharge causing the rope to burn and part. The element may be a metal toroid connected to the head by an electrical conductor, or may be a bell-mouth extension of the head in which the inside arc of the mouth is optionally continued through 3/4 of a circle to create a collar around the head at the point where the fibres emerge. The rope is intended to support an elevated metal structure such as an antenna.

Title: Sealing device for exchangeable loading bodies
IPC: B65F3/00
Filed: 1993-06-11
Abstract: A sealing device for sealing a filling opening in an exchangeable loading body, in particular of a refuse- collection vehicle, comprises at least one closure element which can be placed in or in front of the filling opening in order to seal the filling opening. The closure element, which comprises a closure slide, when the filling opening is opened, is connected to a loading device which is coupled to the exchangeable loading body at the location of the filling opening, the closure slide being accommodated in a frame which is connected to the loading device in such a manner that it can pivot about an essentially vertical axis. The frame can rotate about this pivot axis between a first position, in which the frame is located alongside the loading device, and a second position, in which the frame is located parallel to the wall of the exchangeable loading body which has the filling opening. The sealing device furthermore comprises displacement means for, in the second position of the frame, sliding the closure slide out of the frame into or in front of the filling opening in the exchangeable loading body, after which the closure slide is connected to the exchangeable loading body, and vice versa. The sealing device can be used in a combination of an exchangeable loading body for collecting refuse and a loading device which can be uncoupled from the loading body.
Patent NL-9401765-A (NL)
Title: Rotation lock
Inventor: BAKKER HARM
IPC: F16B39/10
Filed: 1994-10-24
Abstract: The invention provides a device for locking at least two unround elements, for example at least two heads of bolts or screws, which lie at a fixed distance apart in a direction deviating from the axial directions, against rotation, which device comprises a rigid locking element which, with relative rotation locking, can be coupled to each of the unround elements by means of mating unround elements which are adapted so as to interact with the first unround elements. The invention is based on the insight that it is possible, by means of the abovementioned distance, for example a radial distance, and the relative rotation lock between the locking element and the unround element in question, to obtain an absolute rotational lock of both unround elements.
