Patent DE-1951338-A1 (DE)
Title: Production of chocolate articles by moulding
Inventor: VALENTIN ROGER
IPC: A23G1/22
Filed: 1969-10-11
Abstract: Chocolate objects are produced by moulding the hot chocolate in preformed moulds, the hot chocolate being poured into cavities constituted by a sheet of plastic material following the contours of a metallic mould, the chocolate then being cooled in situ in the cavities, whether removed or not from the mould. The moulds are produced by vacuum thermoforming on a metal matrix. The first plastic sheet may be covered by a second plastic sheet after the hot chocolate is poured, and the two sheets combined to form a hermetic container for the initial objects. The hot chocolate is pref. cooled with the mould in situ in the metallic matrix. The sheet of plastic material may be unrolled from a spool and led stepwise past a thermoforming station with the metal matrix, a pourer for hot chocolate, a tapping device, a cooling tunnel, and a cutter. The second sheet of plastic material may also be unwound from a spool, applied to the first sheet after the pouring of the chocolate, and thermally sealed to the first sheet.

Title: Saw-toothed cooling bed - takes various sizes of bar - and flats
IPC: B21B43/00
Filed: 1970-06-02
Abstract: Additional smaller teeth are arranged in between the main teeth of a saw-tooth cooling bed. A modified feeding arrangement allows rolled bars to be delivered to any one of five different pockets that are thus formed. The feeder consists of a stepped plate which may be raised to one of five different positions by means of a crank connected to a hydraulic cylinder.

Title: Automatic regulation of rotary kiln burner supplies - by throttles operated from external three-phase supply through slip rings
Inventor: LANGE WILHELM
IPC: C21B13/08
Filed: 1973-07-07
Abstract: A method of regulating the supply to burners distributed along a rotary kiln operates by throttle valves mounted on the rotary kiln wall. Each throttle valve, is fitted with an adjusting motor, supplied electrically in three-phase from three slip rings mounted on the drum wall. These rings in turn receive threir supply from a three-phase source by contact brushes. Each slip ring is subdivided into a number of segments equal to the number of throttle-adjusting motors to be operated. In addition, the drum possesses a single, undivided slip ring and further, subdivided slip rings for control; the setting of each throttle is indicated by variation in a resistance connected in circuit between, on the one hand the undivided slip ring for all throttle controls, and on the other hand segments of the other control slip rings. The resistances are measured by circuits passing from a control unit, through the control slip rings and undivided slip ring to each of the throttle indicating resistors; variation in the resistance indicated, operating through the control unit, causes a modification to the setting of the corresp. throttle adjusting motor, to be carried out from the three-phase supply.

Title: Neutron-gamma ray well logging - by inelastic scattering of fast neutrons
Inventor: CULVER RICHARD BOYD
IPC: G21H5/00
Filed: 1973-10-03
Abstract: The strata around a well are irradiated with high-energy neutrons; the gamma-rays derived from the inelastic scattering of fast neutrons are measured selectively and their spectral distribution is determined. To facilitate the spectral analysis within the brief neutron pulse, a first measurement is carried out with a pulsed neutron source and a sensor. This alternates with a second measurement with a neutron source with a constant level of emission. The difference between the results of the two measurements indicates the gamma-ray formation by inelastic scattering. The energy discrimination furnishes a spectral analysis and the C/O2 ratio and Si/Ca ratio can be determined.
