Title: Universal batch processor
IPC: A23G3/02
Filed: 1981-03-09
Abstract: A universal processor (10) for batch processing of food products and other liquid or semisolid materials has a hollow-walled cylindrical heat transfer drum (30) adapted to be immersed within a kettle (18) of material for heating or cooling thereof. A rotatable scraper (16) has sets of scraper blades (70, 72) in wiping contact with the inner and outer sidewalls of the drum (30) and is rotated during processing to preclude material build-up on the drum (30). In preferred forms, a drive rotates the drum (30) in a direction opposite to the rotation of the scraper (16). Spiral flighting (74, 76) on the scraper (16) adjacent the sidewalls serves to agitate the material in a predetermined manner for enhanced heat transfer between the drum (30) and material, and for improved blending of ingredients in compounded materials. The drum (30) is particularly dimensioned relative to the kettle (18) for more uniform heat transfer throughout the batch of material. <IMAGE>

Patent GB-2129631-A (GB)
Title: Power control apparatus
Inventor: ALDER JOHN
IPC: H02M3/157
Filed: 1983-09-01
Abstract: A power control arrangement for controlling load power comprises counting means ICI arranged to be driven by clock pulses from the load ac power supply LPS when power is required to be supplied to the load so that said counting means provides a continuously changing coded count output and comparator means IC2 which compares the coded count output from the counting means IC1 with a pre-set or variable correspondingly coded output from power level control means PLC whereby according to whether the count output from the counting means IC1 is greater,equal or less than the coded output from the power level control means PLC the comparator output causes switching means in the load power circuit to be rendered conducting or non-conducting for a number of cycles at the power supply dependent upon the difference between the coded outputs. Thus, in each counting cycle, the switching means is inhibited until the counting means output reaches the preset output of the control means PLC, at which time the switching means is triggered to pass complete supply cycles until the end of the counting cycle. <IMAGE>

Title: Storage heater control apparatus
Inventor: MCINTYRE DR DONALD ALISTAIR
IPC: G05D23/19
Filed: 1984-01-12
Abstract: Relates to an apparatus controlling the supply of heat charge to storage heaters. A storage heater (6) located within a room includes a thermostat (2) responsive to the room temperature. The thermostat has a switch (3) operable at pre-selected higher temperatures, which can be set back to lower temperatures on activation of heater (4). A power control (1) connects power to the storage heater (6) under control of clock (13). During a first period the output of a ramp generator (12) is compared with the output of an outside temperature sensor (11) and is arranged by gates (9) and (8) to activate set back heater (4) until they are equal when, provided the room is cold, the switch (3) opens to cause closing of a circuit breaker (5) connected between the power control (1) and storage heater (6). During a second period clock 13 continuously energises the set back heater (4) and the supply of power to the storage heater (6) is under the control of thermostat (2). Consequently, the storage heater charging is responsive in the first period to outside temperature and responsive in the second period to room temperature. <IMAGE>

Title: A door for load space of a lorry
Inventor: ALANEN ILKKA
IPC: B60J5/04
Filed: 1982-07-28
Abstract: The door of the load space of the lorry, particularly the door of the closed load space which consists of two horizontally on the wall of the load space hinged door halves (2, 3). The door halves have been joined through the lever (9) fitted at least in the other end of the load space, in which case one end of the lever moves along the edging (6) of the higher door half (2) while the door is opened and the other end has been joined for instance with the wire cable (12) to the edging (7) of the lower door half (3). In that case in the opening of the door the rotation of the lower door half (3) downwards can be mediated to the opening of the higher half (2), in other words, to the rotation upwards and correspondingly in the shutting of the door the rotation of the higher door half (2) downwards can be mediated to help in the shutting of the lower door half (3). In that case the handling of the door fitted in the whole wall of the enclosed body is relatively easy by hand power, too.
