Title: Coupling means in a drilling machine
IPC: B25D17/08
Filed: 1975-01-06
Abstract: A drilling machine may include extension equipment comprising (a) drill rods, connected end-to-end, for transmission of impact force and (b) a system of tubular members, likewise connected end-to-end, surrounding the rods for transmission of rotary force. Such extension equipment may be coupled to the machine per se by means of a tubular adapter threadably connected, at one of its ends, to the tubular members system and, at its opposite end, connected to the machine through polygonal coupling means. Inserts or bushings of rubber or similar material may be provided on both sides of said splined connection which in association with such connection renders the extension equipment elastically connected to the drilling machine while also attaining a certain noise-suppressing effect.

Title: Heat exchanger and method for producing the distributing manifold thereof
Inventor: PENKERT RICHARD DIPL-ING
IPC: F28F9/18
Filed: 1982-08-10
Abstract: The invention relates to a heat exchanger, in particular a space heater, having at least one distributing manifold and having finned heat exchange tubes. The latter are connected juxtaposed by a cross-sectional surface in each case to branches of the distributing manifold which open out on the side of the circumference. The heat exchange tube has a guide tube for a heat exchange fluid, and a set of thermally conductive fins on the guide tube in the form of webs which form a front panel, which extends along one side of the guide tube, and a web arrangement which has a central web, which runs starting from the guide tube and extends at a right angle to the front panel, and at least one intermediate web which proceeds from the guide tube at right angles to the central web. In this arrangement, a joint, in particular a welded joint, is constructed between a fin of the respective heat exchanger and a projecting continuation of the distributing manifold which extends along the distributing manifold. At least one intermediate web of the respective heat exchange tube extends parallel to the continuation while overlapping therewith. According to the invention, the web arrangement is open towards the side of the guide tube opposite the front panel, and it is provided that the continuation (50) is joined to an intermediate web (28) of the respective heat exchange tube. It is preferred for the joint to be constructed as a rivet joint or spot weld (54). If the distributing manifold of the heat exchanger is constructed by extrusion accompanied by the integral formation of a continuous continuation extending along the distributing manifold, it is preferred in accordance with the invention for only a single continuation to be provided, and for the latter to be at least partially abraded in the region of the cross-sectional surfaces of the heat exchange tubes which are to be joined. <IMAGE>

Title: Method for the hermetic sealing of a cylindrical housing for a power source, preferably of a power source having alkaline electrolyte, and a device for carrying out this method
Inventor: NABIULLIN FAAT KHATOVICH
IPC: H01M2/04
Filed: 1976-05-04
Abstract: This device has an inner (31) and an outer stamp (30), which are arranged coaxially with respect to one another. An elastic buffer (42) is arranged between the inner stamp and the outer stamp. The outer stamp is provided with two conical recesses (32, 33). The first recess (32) is constructed directly on the end face of the outer stamp and is at an acute angle of 10+/-5 DEG . The second recess (33) is directly adjacent to the first recess and is at an acute angle of 60+/-5 DEG . Once the cover of the cell has been aligned by means of a hold-down device (35), the neck of the housing (3) is temporarily rolled in, by means of the outer stamp (30), as a result of this construction. Once the outer stamp has reached its limit position, the cell is finally sealed by displacement of the inner stamp (31). As a result of the splitting of the rolling process, it is possible to dispense with annealing of the deep-drawn housing. <IMAGE>

IPC: E03B3/28
Filed: 1976-07-15
Abstract: An apparatus for obtaining service water or drinking water from the air moisture in the vicinity of a body of water (1), in particular in the vicinity of the sea, has a U-shaped condenser (7) which dips into the body of water during operation. Above the body of water (1), said condenser is provided with a supply line (11), having an inlet opening (11d), and a discharge line (16) having an outlet opening (19a). In this arrangement, the outlet opening (19a) is situated at a higher level than the inlet opening (11d) and, between the condenser (7) and the outlet opening (19a), there is arranged a vertical discharge-line portion (17) which is sheathed by a layer (17a) which absorbs solar radiation. During operation, the vertical discharge-line portion (17) is heated up by solar radiation, with the result that a convection current is obtained and air, containing water vapour, from the surroundings is sucked through the condenser (7). The water vapour is then liquefied in the condenser (7) and pumped upwards by means of a pump (10). <IMAGE>

Title: Electronic diagnostic equipment - processes analogue signals, includes programming system
IPC: A61B5/024
Filed: 1973-05-09
Granted: 1974-12-06
Abstract: Signals registering blood pressure, temperatures of various parts of the body, cardiac and respiratory rhythms, are connected to a multiplexer circuit ad under automatic control. A selected signal is converted to digital form, stored in an input buffer, then routed into a controller to be inspected, displayed, and recorded on magneic tape. Suitable programming controls the input signals selected, the rate and duration of sampling, and threshold levels of the analogue signals. By varying these factors according to the nature of the signal concerned only relevant data are processed and thus a simpler cheaper system results.
