Title: Support frame for open ditch pipe installation - includes vertically adjustable pipe location cradles in box shaped chamber
Inventor: STUCKMANN DIETER
IPC: E02D17/08
Filed: 1975-05-27
Abstract: An installation frame (14) for pipe laying in an open ditch has a box-shaped support chamber (14-16) which locates the pipe section (10) about to be installed. The base plate (23) of the support frame carries pipe location cradles (41, 42) which are equipped with rollers. Hydraulic cylinders (44) located between the cradle frame and the base plane, are used to position the pipe sections (10) at the same level as the pipe previously installed. When the correct location is reached, hydraulic pusher cylinders apply an axial force on the pipe section so that the pipe moves on the roller cradle to its final position.

Title: Mobile crane load moment limitation equipment - has analogue computer with correcting unit taking account of jib weight
Inventor: KESSEL HEINRICH
IPC: B66C23/90
Filed: 1976-09-11
Abstract: The load moment limitation equipment is for a mobile crane having a slewing superstructure and a variable-length derricking jib, having an actual-value emitter for the moment acting on the crane, while a safe-value emitter using a radius-measuring device and a programme unit determines the maximum values for the different raddi. When the values coincide, a comparator emits a signal stopping any motion, particularly hoisting, tending to increase the moment. The programme unit has an electronic analogue computer with programming and correcting units, partic taking into account the moment acting on the crane due to the weight of the jib itself. The computer can incorporate modules comprising operation amplifiers and adjustable resistances and/or condensers, so as to represent any desired safe load curve.

Title: External window solar heat trap - has regulated vertical air circulation through space between transparent frame held layers
Inventor: ALGAIER ARTHUR J
IPC: E06B7/02
Filed: 1976-09-20
Abstract: The system is designed for reduction of loss of solar heat passing through external wall windows, esp. in cold and temperate climates, and applicable to old buildings and new ones.

Title: Programme selector locked to door opener of washing machine - for automatically dispensing liquid treating agent
Inventor: KORNFELD HEINRICH
IPC: D06F34/30
Filed: 1976-10-29
Abstract: Programme selector for automatically dispensing a liquid treating agent in a washing machine is locked to the door opener of the machine. At the end of each programme actuation of the door opening switch also causes cancelling of the pre-set fabric softener selection. The door opening switch and the selector switch can be in the form of push buttons which are connected to each other by a mechanical locking device so that, on actuation of the door opening switch, the selector switch for dispensing fabric softener springs into the "off' position. Arrangement prevents undesirable dispensation of the treating agent from occuring due to negligence of the user.

Title: Ground compactor for back-filling trenches - comprises tube with compacting foot and vibrator mounted in or outside tube
Inventor: FISCHER HEINZ
IPC: E02D3/054
Filed: 1976-11-19
Abstract: The tube has a depth-stop (7), a removable compacting foot (1') and handles (4) for manual operation. Horizontal vibrations in the tube are produced by a vibrator, which may be contained in the tube (2), mounted on top (5), or fitted outside the tube (2'). An additional vertical acting vibrator may be incorporated, or a high-speed ram may be mountted on the top of the tube. An advantage over conventional forms of compaction is that fine particles are not washed out of the loose granular filling material. The system is also well suited to operation in confined spaces, e.g for backfilling trenches.

Title: Mandrel trip mechanism can printer - has mandrel arms mounted on electronically controlled pivot arms resting against interposer blocks with recessed step
Inventor: SIRVET ENN
IPC: B41F17/14

Title: Sample enrichment for atomic absorption spectrometer - using carbon tube above crucible for secondary evaporation of sample
Inventor: HUBER BERNHARD WERNER
IPC: G01N1/40
Filed: 1977-03-22
Abstract: Enrichment of a particular component in a sample is achieved for use in atomic absorption spectrometers. It has the following steps, a) the sample is placed in a crucible and heated to a first temp at which the desired substance is volatile b) a graphite tube is held at a temp. below this c) an inert gas stream is passed through the crucible and then through the graphite tube, vapourised components being precipitated on the tube walls. The crucible is first heated to a temp. which is below the first but at which disturbing components are volatile. The graphite tube is then held at a temp which is greater than or equal to the specified third temp. Means of heating the crucible and the graphite tube are provided. For use with atomic absorption spectrometers whose certain components interface with measurements of the component required. The system overcomes this problem and allows sample enrichment.

Title: Signal receiver for telephone systems - with voltage of opposite polarities applied to loops in two steps and evaluation of currents
Inventor: FORMANEK KARL ING
IPC: H04Q1/38
Filed: 1977-04-28
Abstract: The receiver decodes code signals represented by adjustable current flow directions of one or several current loops, using currents generated by voltages of opposite polarities applied to the current loops in two steps, esp. for decoding key dialling signals. A decoder has in each loop an input for code signals obtained in the two steps. Input allocated to the first step is connected through an intermediate store, and the input allocated to the second step directly to the output of an optical coupler inserted into the respective loop through a full-wave rectifier, or to the output of an amplifier following such an optical coupler. A polarity changing circuit is used for application of the test voltages. It is controlled by a coincidence circuit monitoring corresp. inputs and outputs of the intermediate store.
