Patent DE-2827375-A1 (DE)
Title: High rise building system - has flow from low to high and separate flow from high to low pressure used to move flow isolating piston
Inventor: RABIEN PETER
IPC: F04C11/00
Filed: 1978-06-22
Abstract: The arrangement is for a system in which there is flow from low pressure (7) to a high pressure (8) and a separate flow in the opposite direction such as in a heating or cooling installation in a high rise building. It comprises a piston (2) in a cylinder (1) which isolates the two flows, valves (5, 6) which alternately opened and closed and non-return valves (3, 4). Alternate operation of the valves (5, 6) causes the piston to reciprocate, causing flow from high to low pressure and separate flow from low to high pressure with minimum energy requirement.

Title: Isolated combined profile rail for doors, windows - has two metal profiles joined by synthetic strip and wedge
IPC: E06B3/263
Filed: 1978-06-29
Abstract: An insulated, combined profiled bar consists of two parallel metal profiles and has support arms and rabbets or latching catches to which a two-part insulating synthetic insert can be fixed securely. The metal profiles are dimensioned relatively to the synthetic profile such that the three pieces to be assembled can be slid along each other. In the metal profile and/or the synthetic profile adhesives are placed, and these are activated when the parallel side walls of the two-part synthetic profile are pressed by a synthetic tightening profile against the corresponding surfaces of the metal profile. This provides a relatively cheap profile bar connection requiring very little machining, and giving a much higher degree of rigidity when the adhesives are activated, so that the joint not only absorbs the forces working on it but transfers the transverse thrust and shear forces to the two metal profiles. The metal profiles can be mass produced together with the synthetic profile, to dimensions which do not have fine limits.

Title: Helical conveyor in hardening plant for small parts - where conveyor is made by bending, cutting and welding sheet metal blanks to produce helical gutter
Inventor: SCHWARZ WALTER
IPC: B65G33/12
Filed: 1978-07-28
Abstract: The conveyor is made starting from several flat ring blanks of sheet metal. Each blank is pressed to form a peripheral rim; and the blanks are welded together in pairs by butt welding their rims, thus forming ring-shaped gutters. Each gutter is then cut to a shape forming part of a helical gutter track; and all the parts are joined together to form a continuous helical gutter. The parts are pref. joined by welding and, for a helix with outside dia. (o.d.) of 500 mm, the dia. of the hole in the blank is pref. 300 mm. When the helix has an o.d. of 1500 mm, the dia. of the hole in the blank is pref. 1000 mm. The pressed rim on the blanks pref. has an internal radius of 25-50 mm for helices with o.d. 500-1500 mm. The conveyor has long life, but is inexpensive to make.

Patent DE-2840952-A1 (DE)
Inventor: ZEMANEK JOSEF DIPL ING
IPC: H04Q11/04
Filed: 1978-09-20
Abstract: A communication circuit arrangement for receiving digital intelligence signals as, for example, in a digital switching center of a PCM-time-division multiplex communication network wherein signals are transmitted on circuits connected to digital subscriber stations and the signals are in the form of intelligence signal blocks having at least one intelligence signal word and including a synchronizing word ahead of the intelligence signal word. So as to compensate for the fluctuating phase relationship occurring in the received signals, the first bit of the intelligent block is determined using a signal evaluation device and a clock pulse signal having a phase which is selected using a clock pulse selection circuit and wherein a synchronous counter is set to zero. The counter generates release signals for a plurality of registers for the individual portions of the intelligence block and a comparator test for the presence of a proper synchronizing word. Depending on the results of this comparison, the adjusting procedures are repeated upon the occurrence of the next block or alternatively the system continues to function with the incoming data. The determination of the first bit of an intelligence signal block allows the selection of a bit clock pulse sequence in proper phase and allows the setting of the synchronous counter which controls the acceptance of intelligence into the various registers.

Title: Electronic alarm timepiece with alarm repetition button - uses voltage supplied to alarm buzzer to activate repetition circuit
IPC: G04G13/00
Filed: 1978-10-23
Abstract: A repetition button allows the alarm signal to be repeated after a defined interval, with integrated circuit element of the timepiece incorporating the repetition circuit and the alarm circuit. The input terminal for the repetition circuit and the output terminal of the alarm circuit are electrically connected to one another via the repetition switch, with the output voltage across the alarm circuit being greater or equal to the threshold voltage of the repetition circuit. Pref. the acoustic alarm signal is provided by a buzzer coupled to the output terminal of the alarm circuit. The repetition button closes the repetition switch between the output of the alarm circuit and the input of the repetition circuit, so that a pulse can be supplied from the alarm circuit to the repetition circuit, so that the latter is activated when the first alarm signal is given. This means that a separate pulse circuit for the repetition circuit is not required.

Title: Nickel catalyst protection against oxidn. - by sorption of fat from soln. on internal surface to maintain hydrogenation activity during transport and storage
Inventor: CZERNY THOMAS
IPC: B01J33/00
Filed: 1978-11-23
Abstract: Protection of Ni catalyst (I) against oxidn. by atmos. O2 is achieved by chemi- and physisorption of an at least monomol. layer of fat from a soln. on the internal surface of (I), without completely filling the pores. An unsatd. soln. of the fat in a solvent is prepd. at a temp. T1, pref. above the m.pt. of the fat (mixt.), then the powdered catalyst is stirred into the soln., the suspension is cooled by 10-50 K and the solvent is pumped away. If the surface requirement is ca. 75 x 10-20 m2/fat mol., a 10-20 mol. layer with a thickness of (1-2) x 10-8 m is formed. The catalyst is pelleted under a pressure of 3-7 MPa, using a solid additive, which passes into the gaseous state below the operating temp. of the reactor in which the catalyst is used, or a hard fat. Catalyst retains its full hydrogenation activity during transport and storage. It is useful in hydrogenation, e.g. of fats.
Patent DE-2851152-A1 (DE)
Inventor: LAURENT FRANCOIS
IPC: G03B17/08
Filed: 1978-11-25
Abstract: A correction lens (C), which is installed in a housing, and a negative auxiliary lens (PMA) are positioned in front of a basic lens (GO). The basic lens is focused at the distance m. The light beam is displaced in parallel by the correction lens, with the result that the focal point shifts to Fa. The position and focal length of the auxiliary lens (PMA) are chosen such that its anterior focal point coincides with the point Fa. If, now, the entire system is immersed in water, the air in front of the correction lens (C) is forced out by the water. Due to the water, the refractive power of the auxiliary lens is reduced and the focal length increases from Fa to Fe. At the same time, however, the focal point Fa is also likewise displaced towards Fe due to the change in the refractive conditions at the correction lens, with the result that the retrofocal setting is maintained even with the system immersed in water. <IMAGE>

Title: Adsorption drier - with alternating drying and regeneration cycles responsive to actual gas flow through appts.
Inventor: KRUEGER CHRISTOPH ING GRAD
IPC: B01D53/047
Filed: 1979-06-05
Abstract: In a compressed gas drier with two adsorbers each continuously switching from drying to regeneration in response to pneumatic valves which send unpressurised dry gas through a previously used adsorber to regenerate it, with a timer controlling valve operations, the pneumatic reversing valves at the adsorber inlets are preceded by gas meters. These meters measure the gas sent through the drying adsorber and vary the operating times or through-puts of both adsorbers so that the amt. of gas supplied to the regenerating adsorber is not unnecessarily high. The change fromone adsorber to the other is dependent on the quantity of gas actually treated, which is not necessarily the set max. possible in a given period, whereas with known devices the change-over was dependent on timing only, which meant an excessive amt. of dry gas could often be used, with waste of gas and energy.
Patent DE-2927565-A1 (DE)
Title: Weft-knit fabric for space-dyeing - using two yarns which regularly alternate between outside and inside of tubular fabric
Inventor: TRENDL FRANZ ING GRAD
IPC: D04B9/34
Filed: 1979-07-07
Abstract: A knitted tubular fabric for space-dyeing is produced by knitting simultaneously two yarns of relatively low count, which are fed to the knitting point one above the other. To ensure a uniform space-dyeing effect on both yarns, they are constantly rotated around each other in alternate directions, whereby they alternate regularly between lying on the inside and the outside of the knitted tube. The alternation is effected at least once, and pref. several times during each rotation of the machine. This method allows fine yarns to be space-dyed on equipment designed for coarser yarns without decreasing the production rate, and with controlled dye-variation which is suitable for use in micro-space tufted products.
