Title: Colour fringing in lamps suppression method - uses mask between light source and projector lens to define cutoff in projected beam
Inventor: GOULD ALLAN VICTOR STEWART
IPC: F21V5/00
Filed: 1976-08-11
Abstract: Lamp has an optical system comprising a light source, a projection lens, a mask disposed between the light source and the projection lens to define a cut-off in the projected beam and an optical element forming an image of the light source at or near the mask. The mask comprises a mask element which is further from the projection lens. The optical element forms a light source image between the mask elements. The projection lens has first and second parts which correspond with the masked and unmasked areas of the light source image. The nearer mask element is between the projection lens and the focus of the first part, whereby the first part produces a virtual erect mask image and the focus of the second part is between the projection lens and the further mask element, whereby the second part produces a real inverted mask image.

Patent DE-2652697-A1 (DE)
Title: Ventilation control with failure alarm - having airflow deflected by pivoted blade controlling reed switch
Inventor: BONGNI ALFRED
IPC: F04D27/00
Filed: 1976-11-19
Abstract: The control regulates the air-flow of a ventilation system and raises an alarm when the flow is interrupted. The air from a fan draws air past a pivoted blade resulting in a turning of its axis so that an attached magnet is drawn towards a reed switch, closing a contact. Any stopage or serious speed reduction of the fan causes the blade to swing, the reed switch contact to open, and an alarm to be sounded. The balance of the pivoted blade is adjusted by a counterweight so that the sensitivity of the device can varied.

Title: Petroleum recovery, esp. from tar sand deposits - by hot air injection after pretreatment with cold air
Inventor: ALLEN JOSEPH COLUMBUS
IPC: E21B43/243
Filed: 1977-03-05
Abstract: Recovery of viscous petroleum from subterranean formations (esp. bitumen from tar sand deposits) is carried out by injecting an O2-contg. gas through an injection well, heating the formation to initiate combustion, injecting more O2-contg. gas to displace the combustion zone through the formation, and recovering petroleum via a producing well. The improvement comprises injecting O2-contg. gas to pretreat the petroleum in the formation for >20 (esp. 50-100) days before initiating combustion. The pretreatment greatly increase petroleum recovery (to 78-85% in field tests and by a factor of >2 in laboratory tests). Laboratory tests indicate that a more uniform temp. gradient through the formation is obtd. after pretreatment.

Title: Multiple power operated vertical venetian blind central control - has overall angle swing activated when guide blind reaches start position preparatory to movement
Inventor: TIPPMANN HEINRICH
IPC: E06B9/36
Filed: 1977-07-27
Abstract: The central control is for swivelling a series of motor-driven venetian blinds which have vertically set slats displaceable horizontally and able to swivel together about their common axis, with drive set alternately for horizontal movement and for swivelling. Slat swivelling for all the blinds is set in motion only when a guiding blind has attained the start position for such a movement. This may be effected by a switch unit activated at the onset of sideways displacement, with an adjustable delay mechanism. The guiding blind may have its own drive with relatively reduced speed of displacement. This facilitates synchronous swivelling, with evenly distributed screening and angle setting according to intensity of light outside.

Patent DE-2740437-A1 (DE)
Inventor: STIEFEL MAX
IPC: B01F1/00
Filed: 1977-09-08
Abstract: Large amounts of a solution consisting of salt and water are required in the case, in particular, of the commissioning of nuclear power stations. In order to prevent the salts from crystallizing out even before the solution is used, it is necessary to produce the solution as near as possible to its place of use. For the purpose of quick and economic production of such a solution, water conveyed by the pump (1) is preheated in the recuperative heat exchanger (3) and brought to the desired temperature in the through-flow heater (4). The water supply line (23) splits downstream of the through-flow heater (4) into a main flow line (39) and a subsidiary flow line (12). With the aid of a jet pump (5) installed in the subsidiary flow line (12), the salt is sucked from a container (7) and guided through a mixer column (11) together with the flow of water which has been guided together again downstream of the jet pump (5). Undissolved salts and contaminants are precipitated in a hydrocyclone (14). The still warm solution is led by way of the line (40) through the recuperative heat exchanger (3) and releases a portion of its heat to the cold water flowing in the water supply line (23). The solution finally passes to be used into the plant through the discharge line (24). <IMAGE>

Title: Long-lasting, odour-suppressing litter for small animals - comprising mixed wood chips and powdered, burned argillaceous earth
Inventor: RAITH ADOLF
IPC: A01K1/015
Filed: 1977-10-31
Abstract: A litter for all types of small animals, esp. cats, mice, cavies, etc. has the advantage not only of being highly absorbent for fluids but also prevents the build up of unpleasant odours, for a relatively long period. It consists of a mixt. of 75-80 wt. % wood chips and 20-25 wt. % of argillaceous earth, burned and bleached pref. at 800 degrees C. This is much cheaper than a litter formed by 100% argillaceous earth burned and bleached at 1400 degrees C and has the further advantage that the granules formed at 800 degrees C fall into powder and so cannot harm small animals with delicate feet.
