Title: Gas burner with low carbon mon:oxide production - has flat and domed wire fabric grids ensuring complete gas combustion
Inventor: HEINEMANN FRITZ
IPC: F23D14/04
Filed: 1977-06-08
Abstract: The gas burner, is similar to a Bunsen burner and is designed to keep the carbon monoxide content low in combustion products. The burner opening (2) is divided uniformly by a screen type wire fabric into several openings. The wire fabric is given a coarse structure by the individual wires in the opening and there is a wire fabric which is domed to form a hemisphere on the burner opening. The laminar gas mixture is finely distributed through the fabric openings and turbulence is caused by the grid structure of the domed wire fabric. This ensures complete combustion and toxic emissions are reduced.

Title: Chain conveyor load carriage drive - is provided by self locking action between chain follower and carriage pawl periphery
Inventor: GEFKEN WERNER ING GRAD
IPC: B61B10/02
Filed: 1978-12-27
Abstract: Moving followers mounted on a draw chain, are used in the drive process for a load carriage in a circulating chain conveyor system with movable pawls. The drive is effected solely by self-locking between a moving follower and the pawl outline. When the carriage is transferred to another draw chain, the original drive motion and new drive motion may simultaneously engage the same pawl. On a suitable conveyor carriage, the pawl runs out in a conical shape at the end, working in conjunction with the follower, with the excitation of the surface facing the follower. In this way switch point transistors are facilitated.

Title: Increasing working life of electric lamps - using module contg. triac and/or diac with C-R element to reduce temp. of filament
IPC: H05B37/02
Filed: 1979-05-26
Abstract: A commercially-available module is connected into the lamp leads so that the effective voltage supplied to the lamp is reduced to 60-80 per cent of the rated value. The module consists of a triac/diac with a capacitor and resistor. The lower working temp. of the filament increases the useful life of the lamp. To compensate for lower illumination a bulb of higher voltage is used, but the shift towards the red component of the spectrum and reduction of the blue by reduced voltage working can give the effect of brighter illumination in any case. The module can be held in a porcelain insulator with terminals.

Title: Temp. control for passenger compartment of bus - regulates air flow by altering ventilation fan speed and fresh-air inlet flap
Inventor: LIEROW ECKHARD
IPC: G05D23/19
Filed: 1979-07-12
Abstract: The temp. control has a sensor measuring the air flow in the air distribution channel. The channel's outlet holes are located in the passenger compartment. The sensor's output is connected to an air-flow regulator. The latter controls the speed of the fan in the channel and the drive that opens/closes the fresh-air inlet flap. The fan is on when the bus is stationary and its speed is gradually reduced as the bus's speed increases (increased flow of fresh air) until it is stopped altogether. The flap is then progressively closed as the speed increases further. The air flow is thereby kept constant irrespective of speed. A thermostat in the bus is coupled to the regulator so that the air flow can be increased when the temp. in the bus rises.
