Title: Smokeless type combustion funnel assembly - has strips over outlet inducing inward air flow to assist combustion
Inventor: REED ROBERT DEHART
IPC: F23G7/08
Filed: 1974-03-27
Abstract: The funnel is for the smokeless combustion of hydrocarbon gases, having a vertical cylindrical chimney in which a rising column of gas is produced. One or more flat strips extend horizontally over part of the chimney outlet from the outside, so as to divide the rising gas column. This produces a lower pressure above the strip and thus draws in air assisting combustion from outside the chimney along the top edge of the strip and into the rising gas columns. The strip can be in the form of a triangular bar, with the apex to the top, or it can comprise a number of radial components secured to a central one. A steam jet can be directed inwards along the top of each strip.

Title: Bolt-setting gun - has safety devices preventing use of wrong cartridges or inadvertent firing
Inventor: PETERS RUDOLF
IPC: B25C1/14
Filed: 1974-05-16
Abstract: The barrel is equipped with safety devices preventing the use of a cartridge of the wrong length, inadvertent firing, or the cocking of the firing pin when the recocking slide is engaged with the driving piston. A recess can be provided at the breech end to accommodate a cartridge of the correct length, working in conjunction with a fixed stop pin on the housing.

Title: Sewage neutralization /detoxification treatment - with parallel collector basin absorbing inflow temporarily when purificn. limits exceeded
Inventor: SALZER RICHARD
IPC: C02F9/00
Filed: 1974-09-25
Abstract: Industrial effluents are continuously neutralised and detoxified in a treatment stage which is continuously monitored by a measurement of the ion concn. or the redox potential. If the signals produced indicate that the neutralisation and/or detoxification degree is outside the desired limits, the inflow and outflow is automatically interrupted and the waste water inflow is collected in a stage parallel to the treatment stage. On reaching the desired value the collected waste water is again admitted to the treatment stage at an infinitely variable rate. Absorbs fluctuations beyond the normal capacity of the treatment stage. The system is simple, reliable and inexpensive; it can be added to existing plants.

Title: Thread cutting control of numerically controlled machine - has transducer driven by main spindle
Inventor: TIETZE ECKART DIPL ING
IPC: G05B19/18
Filed: 1974-11-15

Title: Thermostatic control for domestic oven - enables temperature to be raised above set point during heating up period
Inventor: OSSWALD MANFRED
IPC: G05D23/275
Filed: 1974-11-23
Abstract: The oven has heater elements which are supplied through a seven stage step thermostat which has on/off contacts for each stage. Manual switches open the live supply to contacts above the one selected so restricting control to the selected one. A supply is still left to the next higher stage and when this reaches temperature it energises a relay through its off contact. The relay opens the supply to this stage thus returning control to the selected stage. The relay has a self maintaining contact so that this condition is maintained until the oven is switched off again. The circuit increases the oven air temperature during the time before the food has reached equilibrium with the air in the oven.
