Title: Continuous measurement of concentration of - solutions
Inventor: LUDVIK BORIVOJ
IPC: G01N7/14
Filed: 1969-04-21
Abstract: Solution which can be detected are those which give off gas when reacting with other substances. The liquid to be tested and a solution of the appropriate reagent are fed in a fixed, constant ratio and under consant conditions simultaneously and continuously from below into a vertical tube open at its upper end. The concn. of the substance to be determined is measured by a continuous measurement of the changes in physical characteristics of the resultant mixture e.g. the specific weight of electrical resistivity using either a U tube monometer with a scale that can be tilted or an electrode - bridge circuit.

Title: Stackable, thin-walled plastic covers
IPC: B65D43/02
Filed: 1970-02-21
Abstract: The plastic cover has a frusto-conical upper side.

Title: Cold stretch forming of very large sheets - from circular blanks
IPC: B21C37/02
Filed: 1970-09-05
Abstract: Very large pieces of sheet metal of >5 m dia. are produced by firstly cutting out of a circular blank of the largest possible dia. from sheet rolled to max. width. This is then cold projection stretch formed into a truncated cone, which is then roll pressed over a cylindrical former to yield a cylindrical sleeve, which is spread out by roll forming into a long cylinder, and subjected to a heat treatment.

Patent DE-2127994-A1 (DE)
Title: Gas analyser - with fluorescence source which improves selectivity, sensitivity and efficiency of appts
IPC: G01N21/3504
Filed: 1971-06-05
Abstract: The fluorescence source of the non dispersing gas analyser consists of a container filled with a gas to be detected in an unknown gas mixture and having walls permeable to infrared radiation for the excitement of the fluorescence. The source emits only radiation of the wave length characteristic to the filled gas which is passed through a test cel contng. an unknown gas or gas mixture. A detector measures the absorption of the fluorescence emission spectrum of the gas cpd. passing through the unknown mixture. Increased selectivity can be obtained by interposing a fluorescence filter between the test cell and the detector. Numerous variation in infrared radiation sources, fluorescence sources, detectors as well as analyser configuration are quoted. The instrument is insensible to optical losses.

Title: Thin tube extrusion nozzle - having radial extrusion gap of variable width
Inventor: ROSENBERG ALEXANDR JAKOWLEWITS
IPC: B29C48/09
Filed: 1972-07-13
Abstract: An extruding nozzle for thin-walled polymer tubes comprises an outer tubular casing constituting a frustoconical duct and an inner cylindrical component inside the frustoconical duct, so that mixing chambers and the shaping annular gap are formed between these components. The outer surface of the inner components is fitted with intermittent ribbed spacing annuli. The frustoconical duct widens in the direction of flow and the inner component has a flange-like shoulder at the mouth, extending outwards across the end of the outer casing to form the extrusion gap between them. The inner component is axially slidable, so that this gap can be varied in width. The widening portion immediately upstream of the gap constitutes a mixing chamber. The extrusion nozzle is esp. used for very thin sheets where high uniformity is required e.g. for sausage skins or artificial kidney membranes.

Patent DE-2336773-A1 (DE)
Title: Gear finishing machine with rotary brush - carriage has limit switches for interrupting brush to exchange workpieces
Inventor: RAUSCH HERBERT
IPC: B08B1/04
Filed: 1973-07-19
Abstract: The rotating brush is slidable together with a drive motor on a carriage which is connected to a compression cylinder. The limit switches of the carriage operate by halves to cause the reversal of the cylinder whilst at the end of one cycle, a stroke counter disengages one limit switch so that the rotating brush remains in a harmless end position as the workpiece is changed. The stroke of the carriage and thus the rotating tool is adapted to the work piece by means of adjustable end stops. The carriage can be swivelled by suitable engine so that different sized workpieces, e.g. gear wheels can be machined with the same tool and the carriage is displaceable vertically to its direction of movement on a bedplate.
Patent DE-2345557-A1 (DE)
Title: Machine for recording code characters on magnetic plate - has code wheels fixed on permanent magnet shaft first aligning print and then pressing plate to wheels
Inventor: SOEDERSTROEM GILL
IPC: G11B5/00
Filed: 1973-09-10
Abstract: The machine is for making magnetic plates with coded characters. The setting components are accessible from the outside and are synchronised with the code character wheels. There are several separate rotatable magnetic discs cut like gear wheels with each tooth forming a separate character. The wheels are fined to a permanent magnet shaft with a constant flux. In the first stage of the operation the required characters are assembled and aligned, the drive being tran-smitted by non magnetic gears. In the second stage the plate is brought into contact with the character surface made up by the code wheels.
Patent DE-2348270-A1 (DE)
Title: Cable clamp particularly for overhead cables - has clamping plate made from pressed material with channel which forms cable to wave shape
Inventor: BUECHELE NORBERT
IPC: F16G11/02
Filed: 1973-09-26
Abstract: The clamp has a shell shape and clamps the cable on all sides. As the clamp is pressed together at the different clamping positions, hollow sections of the plate are reduced in size. This has the effect of producing the wave shaping of the cable. The hollow sections are produced from a series of similar breaks in the clamping plate. In addition to the simple flat plate design, there are variations with two cable runs and hollow channels between the runs. In one design there is simply a narrow intervening wall between the cable fairleads. A further single cable design has a ridged top section for holding the clamp and the cable.
Patent DE-2348718-A1 (DE)
Title: Self-service unit with loosely stored bread roll - has coin-operated equipment for individual issue of goods
Inventor: EICHLER RUDOLF
IPC: G07F11/58
Filed: 1973-09-28
Abstract: The self-service unit has coin-operated devices for the individual issue of the goods, which may consist of individual bread rolls. A deflecting angle is arranged above a fork on a conveyor chain so that with each revolution of the fork the fork can pick up only one bread roll at a time. The deflecting angle is provided with slits. The deflecting angle prevents a second bread roll from being able to position itself on the first one on the fork. There is no need for complicated equipment to hold or push down from the fork any excess rolls.

The hub is located about the middle, vertical of the wheel while the top steering arm has its bearing near the inside wall of the wide section. The weight of the suspension is then taken through the middle of the bearing while the toe in angle can be shallow. The brake disc is also located about the middle vertical for max. stability and is bolted to the hub by a locating flange, with the brake callipers located under the wide section of the wheel rim.
Patent DE-2351435-A1 (DE)
Title: Safety mechanism for childs pram frame - has hand operated pram locking mechanism consisting of spikes locating in wheel recesses
Inventor: MUELLER PETER
IPC: B62B9/08
Filed: 1973-10-12
Abstract: The advantage claimed for the design are that the brake is more easily applied than the normal foot operated mechanism and that positive locking of the wheel is an improvement on a brake dependent on friction between the brake arm and pram wheel. The operating lever is fixed to the pushing handle of the pram frame. The spike for each wheel is spring loaded and locates in a shaped disc fitted to the wheel. The spikes are connected by a framework and are moved by a bowden cable. Insertion of the spikes is achieved by pivoting the locking framework on each side of the pram. The hinge mechanism runs parallel to the frame side members.
