Title: Continuous gas calorimeter and indicator - shows instantaneous calorific value against volume using variable drives
IPC: G01K17/06
Filed: 1975-06-26
Abstract: The gas calorimeter consists of a volume meter in the pipeline which gives a pulse output for a known gas volume. A stepping-motor rotates a shaft and operates a counter (9). A bevel gear rotates a truncated cone shaft and second counter via an electro-magnetic clutch controlled by a calorific analyser. a signal proportional to the calorific value of the gas controls the position of a sliding shaft (17)(18) on which is mounted a narrow roller (20) and bevel gear driving a third counter (27). The upper edge of the narrow roller, which is driven by the conical shaft, is visible in a scale window (22) calibrated in Kcal. By suitable choice of gear ratios, the instrument can be made to indicate a wide range of calorific values against gas volumes.

Title: Three phase unbalanced loading protection - involves making use of ripple components in rectified three phase current to produce unbalance current
Inventor: ROELLECKE HUBERT
IPC: H02H3/34
Filed: 1975-07-18
Abstract: The output of three current transformers, one in each phase feeding the load, is applied to a rectifier bridge whose output in turn energises the overload relay. The unbalanced load protection makes use of the voltage developed by this bridge across a loading resistor. The bridge voltage is applied via an integrator and potential divider to one input of an operational amplifier, whilst the other input is connected to the unsmoothed bridge voltage. The amplifier, which is connected in different mode, then gives an output dependant upon the a.c. component of the bridge voltage. In the case of unbalanced load the a.c. component will increase, and a level detector can be made to operate a trip when a predetermined level is reached.

Title: Amplitude modulated optically pumped solid state waveguide laser - has prismatic waveguide layer facing reflector, giving two coherent rays
Inventor: BAUES PETER DR
IPC: G02F1/313
Filed: 1976-05-13
Abstract: Laser has a laser-active waveguide solid layer (I), with one end formed as reflector. (I) forms a 90 degrees prism (P) opposite the reflector (9), the faces (P1,P2) of the prism including an angle of 45 degrees with the long axis (1000) of the laser perpendicular to the reflector. The laser is pumped optically by light sources placed symmetrically to this long axis. The light wave can be aplitude-modulated with little technical expenditure, since 2 coherent rays are produced, which are passed through a phase modulator and then to a 3 dB coupler. It is not necessary to use another 3 dB coupler before the phase modular, so that tolerance problems are avoided. (I) is a YAG:Nd3+ film grown epitaxially on a YAG crystal and 2 rows of luminescent diodes are used for pumping. E.g. a YAG substrate with a YAG:Nd3+ laser-active waveguide layer, pumped by 0.8 um light from 2 rows of GaAlAs luminescent diodes produced light of wavelength 1.06 mu m.
