Title: Sodium tripolyphosphate production using a two-stage operation - in which orthophosphate solution is sprayed onto an orthophosphate granulate fraction and the granulate is calcined by indirect heating
Inventor: BELTING KARL-WILHELM ING GRAD
IPC: F26B11/04
Filed: 1976-01-28
Abstract: The production of Na tripolyphosphate in two stages comprises (a) drying orthophosphate soln. in one unit and recycling a fraction of the resultant orthophosphate granulate onto which is sprayed the orthophosphate soln., and (b) calcining the granulate by an indirect heat treatment. The calcining unit, which is indirectly heated and rotated, is constructed of several concentrically arranged tubes, each welded to a cylinder at one end and encased in a housing, baffle plates being located between the outside of the tubes and inside wall of the housing so as to effect a cross current of the hot gases. The distance between the tubes, and the tubes and the housing, is such that the flow rates of the hot gases are approx. the same. At inlet and outlet sides there are connections for feeding, and in the centre for taking off by suction. Process allows the production of Na tripolyphosphate of low or high bulk density, as required, and with a minimum of waste gas losses, and does not need a large scale dust removal plant.

In nitration mixt wt. ratio (HNO3 + H2O): organic components depends on concn. of HNO3 present and is >=3 in presence of 70% HNO3 and >=8 in presence of 100% HNO3. Nitration mixt. is worked up in a rectifying column. In the rectifying column wt. ratio (HNO3 + H2O): organic components is >=3 (in presence of either 70% HNO3 and mono-nuclear aromatic cpds. or of 78; HNO3 and polynuclear aromatic cpds.) to >=8 (in presence of 100% HNO3 and mono- or poly-nuclear aromatic cpds. The nitration mixt. is charged to a rectifying zone. Conc. HNO3 is removed overhead as present in nitration mixt. In sump, in working up nitration mixts. from nitration of reactive aromatic cpds., HNO3 concn. is 66-70 wt.% and in working up nitration mixts. from nitration of less reactive aromatic cpds. HNO3 concn. is 60-85 wt.%, but always lower than concn. in nitration mixt. Aromatic mono-nitro cpds. are sepd. from the sump outlet of rectifying column. Prods. are used as intermediates in dyestuff prodn. Process requires no specific safety measures, despite the use of conc. HNO3. Nitration mixt. can be worked up in a simple rectifying column. Energy consumption is reduced, as HNO3 for nitration can be recovered direction from nitration mixt. without dilution. Small HNO3 vols. are used.

Title: Heat pump for space heating and hot water system - uses refrigerant operated injection pump to compress working refrigerant and condenser with separate function stages
Inventor: GHALAMFARSA S M CHAHPAR MOSTOF
IPC: F25B1/06
Filed: 1976-06-30
Abstract: Refrigerant passes from the evaporator to an injection pump in which its pressure is raised by a driving stream of hot refrigerant vapour. It flows from the pump through a two stage condenser. The first stage is a calorifier in which domestic hot water is heated and the second stage a heater serving a space heating system. The bulk of the condensed refrigerant flows through an expansion valve to the evaporator. A portion of refrigerant is drawn off after the condenser and delivered by a pump through a heater in a boiler to the injection pump as the driving stream. The pump raises its pressure and the heater evaporates it. The use of the injection pump reduces the capital cost.

Title: Ionising radiation measurement circuit - has counting tubes in probe connected by cable to remote control system which produces operating voltage from tubes
Inventor: MAHNAU HEINRICH
IPC: G01T1/18
Filed: 1976-08-05
Abstract: A coaxial cable is used to transmit the amplified pulses to a distant measuring instrument and to transmit the operating voltage for the counting tubes and/or operating voltage for the pulse amplifier. A voltage-dependent electrical switching device is remotely controllable from the locality of the measuring instrument by changing the value of an operating voltage to be transmitted via the cable. This switch serves to switch on and off and to reverse the counting tubes and/or the probes. The operating voltage of the pulse amplifier which is variable within a certain range can be used a control voltage for the voltage-dependent switch.

Title: Retractable furniture caster - with roller on spring-loaded pivoting fork inside housing controlled by rotary body
Inventor: LESSAU KURT
IPC: B60B33/06
Filed: 1976-12-20
Abstract: Furniture caster comprises two housing halves, a swivel pin, two ball bearings, a roller, a roller fork, a rotary body, a flat spring, a pressure spring and a clamping sleeve. When a vertical load is exerted on the swivel pin sufficient to overcome the pressure spring, the ball end of the pin causes the fork to pivot about an axis, until the fork arm bears against the rotary body. Thus dependent on the rotary body position the roller on the outer end of the fork is either inside or extends outside the housing. Caster is retractable when unloaded, so the load can be distributed more evenly on the carpet, floor, etc.
