Patent DE-3411943-A1 (DE)
Title: Flow-control apparatus
Inventor: SULLIVAN MICHAEL PAUL
IPC: A61M39/22
Filed: 1984-03-30
Abstract: An apparatus having a valve mechanism can be operated manually. The apparatus comprises a housing (10) which surrounds an elastically resilient block of material (42). The housing (10) may be squeezed in order to compress and deform the elastically resilient block (42). Passage ways (50, 60) extend through the elastically resilient block (52) in order to pass a liquid through them. A first passage (50) comprises a solid valve (52) arranged therein. Compression of the elastically resilient block (42) interrupts the seal around the valve (52) by deformation of the passage way (50), so that flow through it is possible. A second passage (60) comprises a capillary tube (62) in order to permit a continuously small volume flow which is not controlled by the operator. This apparatus can be used in connection with intravenous catheters. <IMAGE>

Title: Suspension and filing system for securing pictures or similar articles in an annular container
Inventor: KEERIS PETRUS LEONARDUS MARTIN
IPC: B42F11/00
Filed: 1984-08-14
Abstract: A suspension and filing system is proposed for securing pictures or similar articles by means of a flat securing strip in an annular container which is held open by an elongate slot. The surface of a flexible elongate narrow securing strip is, in this arrangement, provided on at least one side with a self-adhesive securing means and thus serves the purpose of fixing to the front and/or back of a picture or the like. The securing strip contains a recess, on one longitudinal side, which extends approximately to the opposite longitudinal side, which latter longitudinal side is, in each case, retained by its outer ends and by the part which forms the deepest part of the recess, following lateral insertion into the interior of an annular container which only slightly exceeds the length of the securing strip. This securing strip is formed by a fairly rigid flat strip, bent to form an open ring, which is formed in the manner of a frame from two narrower longitudinal parts and two shorter transverse parts connected to the ends thereof, with an elongate recess in between which is separated by a narrower transverse connection. Each flexible securing strip is suspended by being pushed into the slot which is open, or to be kept open at times, and is consequently retained in the annular container, as soon as a picture outside the container ... on the surface which is additionally to be provided with suitable securing means ...

Patent DE-3446660-A1 (DE)
Title: Broadband amplifier, in particular measuring amplifier
Inventor: JANATA EBERHARD DR ING
IPC: H03F1/48
Filed: 1984-12-18
Abstract: A broadband amplifier, in particular measuring amplifier is intended to be produced, with separate, parallel-connected low-frequency and high-frequency amplifiers and a summation amplifier without frequency filters. For this purpose, the invention provides that the high-frequency amplifier A1, the low-frequency amplifier A2 and the summation amplifier A4 are connected in such a way that the low-frequency amplifier A1 compensates for the amplification drop of the high-frequency amplifier A1 at low frequencies, the amplification of the entire amplifier being constant up to the upper limit frequency of the high-frequency amplifier A1. In the concrete embodiment, the low-frequency amplifier A2 is an operational amplifier, and the output of the summation amplifier A4 is connected via an attenuator A3 to the inverting input. An amplifier is thus obtained in simple fashion which, along with the high-frequency characteristics, such as broadband characteristics, also has the excellent DC voltage characteristics, such as zero-line stability and low input current, of an operational amplifier. <IMAGE>

Patent DE-3508129-A1 (DE)
Title: Compressed-air hose appliance
Inventor: VOGLIANO GERMAN
IPC: A62B7/12
Filed: 1985-03-07

Patent DE-3515673-A1 (DE)
Title: Feeding device for a roller press
Inventor: BLECKMANN HUGO DR
IPC: B30B15/30
Filed: 1985-05-02
Abstract: The invention relates to a feeding device for a roller press, comprising a rectangular feeding chute having side walls and partitions which are arranged transversely to the longitudinal direction of the nip and almost project into the nip. Known feeding devices have the disadvantage that when quantities of material to be fed for pressing are changed rapidly, pressed pieces and/or shells are produced with greatly varying and/or inadequate mechanical strength properties. According to the invention, these disadvantages are eliminated and a self-regulating production of pressed pieces of uniform mechanical strength is achieved by giving the partitions (5) different heights in the feeding chute (2), above which a feed device (6) which is laterally offset from the centre of the feeding chute (2) in the longitudinal direction of the nip is arranged for the material to be pressed. <IMAGE>

Title: Scrubbing water treatment for simultaneous SO2 and NOx gas purification with conversion of dithionates and salts of sulphonic acid
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/68
Filed: 1985-07-27
Abstract: The main application P 3519681.5 relates to water treatment for simultaneous SO2/NOx gas purification. In this process, a part-stream of the scrubbing water circulation (1) reacts in a vessel (3) with hydrated lime (2). In order to further improve this process, according to the invention, a short-lived dispersing agent (28) based on a polycarboxylic acid is added to the part-stream of the scrubbing water circulation (1), in order to increase the settling of CaSO3 . 1/2H2O - CaSO4 . 2H2O - and FeII/FeIII hydroxide solids, without interfering with the downstream reactions for scrubbing water treatment. In a further embodiment, the acidic waste water (filtrate) from the EDTA precipitation is not treated in an evaporation plant or spray-drying plant, but in a digestion plant composed of a heat exchanger, through-flow heater, circulation and conveying lines and a pollutant return line to the untreated gas upstream of the scrubber, where, to convert dithionates and salts of sulphonic acid such as HON(SO3Na)2, NH(SO3Na)2, N(SO3Na)3 into sulphate and sulphite, strongly acidified solutions of such salts, with or without the application of pressure, are heated for a defined time via heat exchangers and decompose in the course of this (Figure 1). <IMAGE>

Title: Appliance for suppressing one's own snoring during sleep
Inventor: ANDJULOVICI ALEXEI DIPL ING
IPC: A61F5/56
Filed: 1985-08-21
Abstract: The invention relates to an appliance for suppressing one's own snoring during sleep. The appliance functions as follows: a small microphone attached somewhere on the head of the person (using sticking tape) receives the snoring noises of the snoring person and passes them to an electronic pocket device with battery, placed in the pyjama pocket. This device receives the noises coming from the microphone and processes them only when they reach a certain volume. The correspondingly louder snoring noises, which as electrical signals have exceeded the sensitivity threshold of the device, are electrically amplified, distorted and sent through an amplitude limiter to an earpiece fitted in the ear. The sensitivity, volume and amplitude limiter of the device can be preset according to the requirements of the user. The connection between the microphone, the device and the earpiece is made by means of a flexible, thin, insulated lead. The drawing represents the appliance on the sleeping person, where:     1 is the microphone,   2 is the electronic device,   8 is the earpiece,   10 are the connecting leads.   <IMAGE>

Title: Locking device for a motor vehicle seat
Inventor: THILL ALBERT
IPC: B60N2/30
Filed: 1985-11-15
Abstract: A seat cushion (1), which can be swivelled up about its front edge (7), of a motor vehicle seat is locked in its normal position against undesired pivoting up by means of a holding component which is attached to the seat cushion, has a stop, is constructed as a spring and is in an operative connection with a counterstop fixed to the vehicle body. Even when the seat cushion (1') is in an upright position, the locking device is to lie outside the head-impact area of a vehicle occupant located next to the upright seat cushion. This measure is achieved in that the spring (15) is constructed as a leg spring, one leg (18) of which is permanently connected to the seat cushion (1) and the other leg (19) of which constitutes the holding component which is assigned a hook (11) as counterstop, which hook (11) is fixed to the vehicle and engages in the locked position behind the other leg (19). <IMAGE>
