Patent DE-2935154-A1 (DE)
Title: Recording and removing system for incompletely filled trays - uses reflected light from light source above tray to indicate absence or presence of product in tray (BE 2.3.81)
Inventor: GRUBE GERHARD
IPC: G01N33/00
Filed: 1979-08-31
Abstract: The system uses light reflected from the bottom of a tray to indicate the presence or absence of a product in the tray. (The tray is covered with a top foil by the packing machine). The light source is located above the optical receiver that detects the reflected light. The receiver area of the receiver is greater than the area occupied by the product in the tray and facing the receiver. The amplitude of the receiver's output signal is monitored and used as criteria for removing a tray (because it contains no product). A comparator is used to compare the output signal with a reference. The comparator initiates removal and also causes a digital counter to move on one digit. The counter counts the number of trays removed.

Title: Sleeve protecting thermoplastic pipe against fire - formed by ring sector strips of highly compressed thermally expandable material
Inventor: DOMNICK ARNO
IPC: F16L5/02
Filed: 1979-10-19
Abstract: Tightly compressed granular material is moulded into strips having the cross-section of ring sectors, and assembled to form sleeves of thermally expandable material giving thermoplastic pipes protection against fire. The ring sectors are closed at their circumferential side, and at least on their rear side they are embedded into backing plates. The sectors may be attached at their outsides so that they can be unrolled and laid flat. Flexible plates may be used to join the sectors. A sealing layer, possibly of crimp film may enclose the sectors. Smaller ring sectors may be assembled in groups with sector-form backplates. The rear plates of the sectors may have projections engaging with cutouts in the connecting plates. Forms a sleeve giving protection against fire hazards, which is robust and economic in transport and storage costs. The sectors can be manufactured in a simple and cheap manner. The details are easily assembled into sleeves, and may consist of ring-sector-form strips subtending an angle =5 degrees.

Title: Hydraulic damper mineral filling material - is electrically non-conductive powder with low hardness
Inventor: STOLBERG FRITZ DIPL ING
IPC: F16F9/00
Filed: 1979-12-28
Abstract: The mineral filling material is designed to operate as a damping medium in hydraulic dampers. It is electrically non-conductive, with a hardness corresponding to the three lowermost gradings of the Mohs scale.

Filed: 1980-06-26
Abstract: Process and apparatus for treating material by applying non-sinusoidal vibrations. In apparatus for separating solids from the liquid phase of a dispersion, non-sinusoidal vibration is applied by vibrating at least a portion of a wall of a receptacle for the dispersion or by a vibrating plate, a pair of vibrating plates or a hollow body in the receptacle. In a roller mill for crushing material one of the rollers is vibrated axially relative to the other. In a juice press a vibrating plate is provided at the bottom of the press cylinder. In a jaw crusher, one of the jaws is vibrated in a direction parallel to the face of the jaw. In a ball mill comprising a cylinder rotating on a horizontal axis, the cylinder is vibrated in an axial direction. Non-sinusoidal vibration is produced by a hydraulic servomotor fed with pulses of hydraulic pressure fluid by a rotary control valve.

Title: Additional telegraphic facility equipment in telephone exchange - has controlling changeover relay contacts responding to terminal input code
Inventor: BAER GERHARD ING GRAD
IPC: H04Q11/04
Filed: 1980-10-23
Abstract: The equipment enables special facilities, e.g. Prestel (RTM) to be accessed by telephone subscribers through a conventional telephone exchange without causing blocking and without expensive modification to the exchange. The special facility traffic is separated from conventional traffic and directed to input access points to the special facility selection equipment. The line current to telephone is closely controlled and the facility is accessed using a dialled code. Charging facilities are also provided. Normally the telephone is connected to the exchange via an exchange line through change-over contacts. To use the video-text facility the subscriber sends from a remote control via the TV receiver into the data modem causing change-over contacts to operate causing little current to be drawn so that the exchange circuitry does not operate. Tone recognition from the modem source causes change-over of the line contacts to connect the modem to the video-text computer lines.

Title: Drawing cross-hatching appts. - uses ruler movable along length axis of smooth guide rod and has check lever with control stop subject to directed force
Inventor: ROSENAU VIKTOR
IPC: B43L7/08
Filed: 1980-11-12
Abstract: The cross hatching appts. has a check lever-staging device. The ruler (5) along which the lines of the hatching are drawn using a pencil or pen is attached to a smooth rod (4) located on a fixed base section (base plate 1) and arranged to be movable along the length axis of the rod. It is moved by a check lever (7) up to a stop for this check lever (9) by a force acting along the length axis of the rod (4) such as finger pressure. The check lever (7) seated on the rod with some play is held on the rod by the fact that the force acts on the check lever (7) at some distance from the length axis of the rod (4) and on the point of contact of the tension of a spring acting in the opposite direction.

Filed: 1981-03-07
Abstract: In typewriters and similar machines with a motor which can be driven incrementally in order to position the printing unit (1), it is possible to position the printing unit in fine increments and thus to print characters outside the normal character spacing. Storing in a data memory (12) the fine-increment position in association with the respectively printed character permits the exact position of the character to be detected automatically when repositioning, for example for the purpose of deleting characters, and permits the printing unit also to be set exactly to characters which are printed outside the normal character spacing. <IMAGE>
