Title: Composite profile window frame with flexible thermal insulation - is made by trapping flexible profile between profiles
Inventor: MEYER WILLI
IPC: E06B3/263
Filed: 1975-01-31
Abstract: The composite profile for window frames has an inner profile and an external profile which has two flanges projecting towards the inner profile. These two metal profiles are connected with a thermally insulating material profile so that it is no longer necessary to inject hardenable filler which will impair the flexible nature of the connecting insulating profile. One of the profiles has a projecting hollow rib (9) whose edges have beads (11). A flexible profile (3) is folded over this rib and held by beads. The other profile (1) has two ribs (4) with hooking edges (6) which hold and trap the flexible profile so that the two profiles cannot be separated.

Title: Formation of deposited metal screens - using former with elastic material in holes ground down at temp. below 0 deg.C.
Inventor: JAN WOLFGANG VAN ING GRAD
IPC: C25D1/10
Filed: 1975-02-22
Abstract: Process for producing a sieve type matrix for the electrolytic deposition of sieve like metal foils uses a body into which have been impressed the required pattern of holes or perforations. The depressions so formed are then filled with a material which is flexible and elastic at room temps. or higher, but which is firm and rigid when cooled to 0 degree C. or below. It can then be ground and polished at the reduced temp. The material may be a natural or synthetic rubber-like material. It should pref. be cooled to between -20 and -30 degrees C. Suitable for forming "rotex-sten ils" for printing, shaving screens, technical sieves, pressure switches and heating foils. Overcomes the problem associated with this process of removing the elastic material at normal temp. When removed at low temps. it becomes much more rigid and brittle and easy to grind off. At normal temps. it regains its elasticity.

Title: Gritting attachment for train wheels - with magnetic applicator to ensure correct spreading rate for driving and braking wheels
Inventor: RAPPENGLUECK WALTER
IPC: B61C15/10
Filed: 1975-06-20
Abstract: The locomotive is fitted with gritting attachments to cover the top of the rails with grit in front of the driving and braking wheels.

Title: Rotary guide frame for radial drilling machine - is held in bearing rings for swivel movement above lower frame
Inventor: MUELLER HELLMUT DIPL ING
IPC: B23Q1/28
Filed: 1975-07-14
Abstract: The radial drilling machine has a drilling column and a lower frame, with a column guide frame, acting as a rotary frame, installed between them to form a combines assembly with the column. The guide frame is rotatably fixed at its lower end to the lower machine frame, and is raised up from its bearing position to absorb bending and torsional forces. The bearing (1) for relative swivel movement between rotary frame (2) and lower frame (3) is disengaged from machine working pressure and clamping force arising from the fixture of the rotary frame (2) to the lower frame (3), since it (1) is directly or indirectly connected to the rotary frame (2) and via bearing rings (5, 6) to the lower frame (3). The rotary frame (3) has a stop (7), enabling it to be clamped (11) to the lower frame (3).

Title: Determination of oil density in aq. phase - by ultraviolet light irradiation of dried sample on gel with fluorescence indicator
IPC: G01N25/14
Filed: 1975-07-23
Abstract: The residual oil and/or the oil content in effluents of grease separators, metal cleaning liquor and other industrial wastes is checked by extracting a sample with a readily volatile solvent. The extract is freed from solvent at a temp. below the b. pt. of the solvent in a dish, lined with an optically and chemically inert non-hygroscopic gel and an added fluorescene indicator. The dried out mass is exposed to short-or long-wave ultraviolet light and compared against a reference sample for fluorescence intensity differences. This system is applicable to a very wide range from 0.1 to 1000 mg litre in aq. phase and is extremely rapid. The usual two days delay for conventional methods is saved.
Patent DE-2540001-A1 (DE)
Title: Rolling bearing for gear box shaft - has running flange on inner bearing race for gear revolving on shaft
Inventor: ASHAUER KARL
IPC: F16H63/30
Filed: 1975-09-09
Abstract: The rolling bearing has the end of the inner race which faces the rotating gear wheel provided with a collar or flange which forms a running surface for the end face of the gear wheel. Thus, a separate wear disc located between the bearing and the gear wheel can be eliminated. It is only necessary to grind the two mating surfaces of the inner race and the gear wheel; some mfg. operations can be eliminated and the number of dimensional tolerances involved is reduced. The race (4) is fitted with a collar (5), and the ground end surface of the collar (5) forms a running face for the end surface of gear (6), so it is now unnecessary to use a wear-ring between the bearing (3) and gear (6).
Patent DE-2545277-A1 (DE)
Title: Cutting an extruded tubular film along the edges - to obtain two accurately trimmed webs with minimal waste, for reeling up
Inventor: SCHMIDT HEINZ
IPC: B26D1/03
Filed: 1975-10-09
Abstract: An extruded, seamless, flattened, tubular, thermoplastics film is cut along its edges to give two congruent webs for reeling up, by marginally trimming it whilst scanning >=1 of the edges. The distance between edge guide and trimming knife is adjusted so tha the latter only just catches the web. The resulting cut webs are then conveyed perpendicularly to the winding-up station. Neatly and accurately trimmed slit webs are obtd. that require no post-trimming. Since the trimming knife slits the tubular film extremely narrowly along the margin there is a min. of waste.

Title: Still TV picture transmission with audio accompaniment - includes transmitter equipped with picture sequence store and audio signal store
Inventor: STREHL HERBERT DIPL ING
IPC: H04N1/00
Filed: 1975-12-09
Abstract: The still television picture transmission system, with audio accompaniment, transmits still pictures to subscribers via tv or video telephone channels using TDM methods. Still pictures are grouped into sequences and repeatedly transmitted over one channel. At the receiver these still pictures are stored and can be selected in any order. Each still is retained until the next still in the sequence can be stored and reproduced. The digitally converted audio signal is compressed for transmission with its picture and then expanded at the receiver. Hundreds of programs (eg news reports, market prices, sports results etc) may be transmitted over the same channel continuously throughout the day.
