Title: Calcium cyanamide stabilization - by spraying with calcium nitrate soln
IPC: C01C3/18
Filed: 1970-12-30
Abstract: The storability of granular calcium cyanamide produced by nitrification of granulated calcium carbide is improved by (a) heating the granular calcium cyanamide to 100-150 degrees C, with constant agitation; (b) spraying with a hot calcium nitrate soln., opt. portionwise (the product being dried between the addn. of individual portions); and, after completion of the addn. of Ca(NO3)2 soln., (c) treating the product with air at =120 degrees C. Calcium cyanamide fines (particle size 0.2mm, 20-30 wt.% 30 mu) may be dusted on to the sprayed granules after each spraying (but before drying) when a portionwise spraying technique is used. The calcium cyanamide product is rendered insensitive to atmospheric moisture without adversely affecting its high cyanamide nitrogen content or its high resistance to abrasion.

Title: Data reckoner with window and sliding scale - shaped to give easy jam-free motion has bevelled edges which slide off edges of window
Inventor: DUELL HELMUT
IPC: G06G1/04
Filed: 1973-07-14
Abstract: A slide moving inside a rectangular envelope with windows has its narrow side edge shaped at an angle to avoid jamming against window edges. The narrow side of the slide has also a rounded concave shape so that the bevelled edge gradually passes the window thus avoiding jamming due to the whole length of the edge coming against the edge of the window at one time. The slide may thus be easily withdrawn and replaced. The reckoner may be an ordinary slide rule or a calculator working on some other principle.

Title: Continuous colorimetric analysis - where sample and test reagent are heated above boiling pt in capillary tube
Inventor: SIMATUPANG DR IR
IPC: G01N21/25
Filed: 1974-03-21
Abstract: Process for continuous colorimetric analysis at high temps. consists of pumping the continuously flowing liquid for analysis into a capillary tube together with the test reagent and heating to above the boiling pt. Subsequently, either before or after the colorimetric determination (M) it is cooled until no disturbing air bubbles are present. In chromatography, colourless outputs from a column can be detected by colorimetric methods with the aid of reagents to give coloured products. In general the effectiveness of such reactions is increased, the higher the temp. at which they are carried out. Methods currently available cannot exceed the boiling pt. of water. The method described permits temps. in excess of this to be used.

Title: Commutating supply for thyristors in motor drive - derived from separate source to ensure correct operation
Inventor: SCHADE WALTER DR
IPC: H02P23/28
Filed: 1974-07-08
Abstract: The application is to thyristor inverters, for example as used for variable speed induction motor or similar drives, where the individual paths have to be cyclically switched to establish and interrupt current in a regular sequence. As such drives also employ variable voltage a self supplied commutating circuit may be unreliable at low voltages and produce dangerously high current surges at high voltages. A separate commutating supply is therefore proposed which is independent of the main power supply. Typically one pole of this auxiliary supply is connected to one side of the main d.c. supply and the other pole to a separate auxiliary busbar.

Title: Hinge arrangement for skylight window - has bend in hinge plate for forming positive seal
IPC: E05D5/06
Filed: 1974-07-24
Abstract: The rotating window is rotated about a horizontal axis and the side member of the moving frame supports a hinge consisting of two brackets connected by a hinge pin. The penetration of moisture and draught forming gaps are prevented in the hinge region by a projecting U cross section engaging channel in both hinge plates. The moving frame carries a hinge plate (8) on a fixed frame bent near the hinge pin to form a U shaped cross section channel which projects sideways so that it contacts the similar upwards projecting side (16) of the channel in the hinge plate (7) on the moving frame. This hinge assembly is fitted at about mid length of the side members of the moving frame so that the ends of this frame are released from contact with the fixed frame.
