Title: Heating and cooling pasteuriser vessel for liq. food prods. - has exterior cooling coil of rectangular tube inside heater jacket
IPC: A23G9/30
Filed: 1976-03-26
Abstract: The coil is made of tube of rectangular cross-section in material which conducts heat efficiently. The inner flat face of the rectangular cross-section contacts the wall of the vessel continuously as it winds around it. The ends of the coil are connected in a circuit with a refrigerating system. The outer flat face of the rectangular cross-section tube is surrounded by a heating jacket, pref. in the form of electric elements in contact with the tube and forming a jacket around the coil. The coil is pref. made as a multi-start helix with inlets and outlets connected into a single inlet manifold and a single outlet manifold. A pasteruriser to liq. and creamy foodstuffs esp. prods. made from milk and fresh cream is produced. When the pasteuriser had a cooling coil of circular cross-section, embedded in thermally conductive cement to improve heat transfer to the vessel, heat application was limited to 100 degrees C by immersion in hot water. The coil and cement required constant maintenance and heating was inefficient due to only line contact between coil and vessel. These problems are now overcome.

Title: Numerical positioning of work-table on machine tool - uses pulses from motor counted off with reference to limit switch defining origin of coordinates
IPC: B23Q15/24
Filed: 1976-05-07
Abstract: The numerical control positioning system consists of a keyboard connected to the control unit. A clock unit emits pulses through two AND-gates and a pulse counter to a binary encoder. The exits from the encoder are taken via amplifiers to the windings of the motor which turns the leadscrew controlling the position of the worktable. The motor has a pole armature with 8 field poles wound in alternate senses. A limit switch connected to the NOR gate and the AND gate to the pulse counter defines the origin of the coordinates. To set the worktable the control unit sends out the required number of pulses from the clock and stops the motor when it has returned the same number of pulses.
