Patent DE-2163572-A1 (DE)
Title: Moil removal - from hollow glass bodies
Inventor: LUSH JOHN S
IPC: C03B33/085
Filed: 1971-12-21
Abstract: Apparatus for cracking off moil from hollow glass articles is arranged to receive rows of moulded glass articles as they leave a lehr and transfer them into a single line conveyor, which feeds them to a rotating turret on a crack-off machine using a feed screw and transfer wheel which presents the articles in turn to a crack off device and then to edge polishing nozzles. The articles are then fed into an annealing machine, and are rotated on the crack off chucks on which they are heated on the rotating turret. The crack-off device comprises a heating flame directed at the articles along a predetermined line at the top edge of the required position, a rotating cutting knife to strike the heated part, operated by an air blast, and a cushioned drive. The apparatus is especially for use with thin glass tumblers which require no mechanical finishing or polishing and is adapted to fast efficient throughput.

Title: Precast concrete stacking and hardening - in racks with vertical displacement mechanism
Inventor: RIKER RUDOLF
IPC: B28B11/24
Filed: 1973-03-10
Abstract: Large area, horizontally cast, flat concrete components are hardened out using minimum floor space by use of a system requiring no external lifting tackle, in which the pallets with the components are automatically introduced into a stacking rack in which they are discontinuously raised whilst being heated. There are then either taken off at the top or transferred by a horizontal transfer mechanism to another stacking rack in which they travel intermittently downwards whilst being cooled. The lifting is affected by a hydraulic jack in the bottom which raises the pallets onto pins of racks which are moved by pinions successive pallets having legs acting as spacers. The system saves floor space and is used in pre-cast concrete manufacture.

Inventor: SACHS WOLFGANG
IPC: F27B1/16
Filed: 1973-04-05
Abstract: Vertival shaft cupola furnace is fitted with groups of tuyeres at >= two different levels. A primary first gp. is below the melting zone and blows in 50-85% of the blasting air, whilst a sec. gp. opens into the shaft at or above melting zone level and introduces 15-50% of the total blasting air vol. Each set has its separate wind box and equal vols. of air per unit time are introduced through all tuyeres of a given gp. Each wind box may have its own blower or they may have a common blower in which latter case adjustment valves etc. are required in the system. The systems allows a redn. in the quality and quantity of coke used in the cupolas and gives rise to faster melting and carbon take-up rates. The cupola is used for cast iron and especially Meehanite (R.T.M.) C.I. melting.

Title: Adhering meat removal off bones - by compressed air jets in rotatable wire mesh drum
Inventor: KOENIGER HELMUT
IPC: A22C17/04
Filed: 1973-04-26
Abstract: Adhering meat remnants are removed from bones in a wire mesh drum which can be rotatable around a vertical axis. A number of pointed compressed air jets are directed slightly upwards and semi-tangentially into the drum so that the bones are stirred up, the drum is rotated and the meat is separated from the bones which remain inside the drum. This saves the manual labour required to clean up bones if excessive losses of edible meat are to be avoided.

Title: Electrocardiogram signal processor - has discriminator threshold adjuster operating for given time interval
Inventor: MAAS MICHAEL
IPC: A61B5/04
Filed: 1973-12-13
Abstract: Electrocardiogram receiver or processor has an adjustable damping unit with high damping when the signal amplitudes exceed the threshold of a discriminator. A measurement element is connected in the signal path before the damping unit, and detects presence of signal fractions with excessive amplitudes w.r.t. the normal case, to raise the threshold discriminator's threshold, via a threshold regulator, for a preset time interval above the normal level. Loss of signal amplitudes which may be of interest for processing, owing to occurrence of abnormally high signal amplitudes, is prevented. The threshold regulator includes a transistor and a charge reversing capacitor.

Title: Temperature control for an electrically heated incandescent igniter - the incandescent filament is incorporated in a spark monitoring system
Inventor: BARTELS WILLY
IPC: F23Q7/10
Filed: 1974-02-19
Abstract: The electrically heated incandescent filament is used for igniting air and fuel mixtures in the cylinder of motor vehicles. The igniting process is, monitored by this system and the control system ensures that the resistance element is not burnt out owing to the heat supplied by electricity which is augmented by the flame within the cylinder. The incandescent resistor is fitted into a bridge circuit and the current supply is controlled by means of a control circuit so that the resistor is held at a certain temperature or at a certain resistance value. The control circuit controls the amplitude of the current supply and it can also control the pulse length of the current supplied. The current flowing through the resistor is used also as a control signal for the monitoring arrangement for the flame of the fuel and air mixture. The ignition system does not generate sparks which could generate signals which interfere with wireless reception in the vehicle.

Title: Electromagnetic recording and playback unit - has tape tensioning motors and switching arrangement to control motors
Inventor: APPEL ADOLF
IPC: G11B15/43
Filed: 1974-05-10

Controllable rectifiers in the power supply can be used to feed power to the control stages of the tape tensioning motors. In the switching arrangement controlling one or more of the motors, a control-value transmitter produces according to the position of tape tension sensors a control signal which controls the power supply to the motors and is given negative or positive polarity by switching elements.

Inventor: JAKOB PETER MICHAEL
IPC: B29C45/46
Filed: 1974-06-10
Abstract: In injection moulding the fused material is injected under pressure into a cavity and when a set pressure is reached in the cavity it is subjected to a reduced pressure; when the cavity is full the material adjacent to it is partly diverted into a side chamber, so as to speed up the changeover from the full to the reduced pressure. A simple and precise method of speeding up drop in pressure is provided.
Patent DE-2436995-A1 (DE)
Title: Remote adjusted wing mirror - with integral electric motor and eccentric coupling driven via gears
Inventor: ZILLNER GUENTER
IPC: B60R1/072
Filed: 1974-08-01
Abstract: The wing mirror has the mirror (1) mounted on a support plate which is mounted on a universal joint. The mirror fitting is linked to the housing by a flexible membrane to prevent ingress of dirt and water. A small electric motor is mounted behind the mirror and drives the mirror mounting via a reduction gearing and a special eccentric coupling. This increases the eccentricity with each sweep of the mirror so that when the electric motor is operated from inside the car the mirror 'sweeps' different field of view until the driver is satisfied with the adjustment. The mirror is fitted to any vehicle without requiring complicated cable and lever linkages.
Patent DE-2437414-A1 (DE)
Title: Capacitance and dissipation factor measuring bridge - collects test voltage through high resistance directly from the tested capacitor
Inventor: BENZ OTTO
IPC: G01R27/26
Filed: 1974-08-02
Abstract: The collected test voltage is applied to a reference capacitor (CN) with a measurement circuit at its low voltage side; this circuit has a balancing point at an amplifier input, at which inverted current proportional to the current through the tested capacitor (CX), and two reference currents whose phases differ by 90 deg., are added; this sum is reduced to zero by the amplifier through a negative feed-back resistor; when the balance is not perfect, amplifier output voltage operates control elements for the capacitor and dissipation factor. All amplifiers are so designed, that a virtual zero potential exists at their inverting input; current flowing through the capacitor is applied directly or through resistors to the zero potential point of an amplifier (V1); its output voltage is applied through a resistor (R10) to the balancing point (AP); the balance is achieved by adjustment of currents (iCN, iRN).
