Title: Dish washer with improved drying process - has small amounts of unheated air supplied in timer-controlled cycles
Inventor: WEIHING KURT
IPC: A47L15/48
Filed: 1974-02-01
Abstract: The programme-controlled dishwasher comprises at least one air inlet which opens into the interior of the machine containing the dishes as well. The air flows through this inlet into the inner chamber and then out through an air outlet which is also provided in the dish washer chamber. The supply of fresh air is controlled in cycles by a programme control mechanism and is kept relatively low which was found to produce the best drying results. The small volume of air leaving the inner chamber only carries along relatively small amounts of water which are not sufficient to adversely affect the machine or the atmosphere around the machine. The fresh air is only blown on in cycles which do not begin until halfway through the drying process. The amount of air supplied is preferably smaller than the inner volume of the container, preferably 0.4 to 0.6 times the inner volume.

Title: Distribution of recorded speech or music - whereby record stack is reversed for continuation
Inventor: DIETZSCH ROLF
IPC: G11B3/68
Filed: 1974-02-26
Abstract: Where a musical or other performance is recorded on gramophone records and the work is too long to be contained on one side of the record, a decision has to be made as to whether to continue on the reverse side or use some other system. Here the proposal is to continue the performance exclusively on single sides of other records, so facilitating reproduction on automatic record changers i.e. a performance of symphony A would be recorded consecutively on the upper sides of records 1, 2 and 3, while symphony B would be recorded consecutively on the reverse side of records 3, 2, and 1.

Title: Injection mould heated and cooled by cylindrical plugs - screwed into mould wall each having heating cartridges and cooling ducts
Inventor: HARTIG GUENTER ING GRAD
IPC: B29C45/73
Filed: 1974-08-21
Abstract: A device for modifying the temp. of the walls of a platics injection mould comprises a number of separate units each of which can be inserted into the wall of the mould, each unit consit of an outer tube or sleeve of highly thermally conducting material, and of an electrically heated cartridge mounted coaxially inside this sleeve, the space between this cartridge and the sleeve is occupied partly by coolant ducts permitting a coolant to be conducted inside the sleeve, and partl by thermal bridges conducting heat from the electrically heated cartridge to the sleeve. In a preferred embodiment the coolant inlet and outlet consist of stub-pipes projecting away frm the sleeve and each communicating with a generally axis-parallel duct on each side of the heating cartridge with a transverse communicating duct between the inner end of the cartridge and the closed end of the outer sleeve, so that the cooling fluid can flow axially along one side of the cartridge and return along the other side. The thermla bridges between teh cartridge and the surrounding sleeve are formed of material posessing good thermal conductivity, occupying the segmental shaped spaces between these two coolant ducts. In this preferred embodiment also, the sleeve has an external thread around an annular collar enabling it to be fitted in the wall of the mould and is closed at its inner end by a highly thermally conducting plug. This plug is separated by insulating layers from the sleeve and from the interior of the sleeve, a groove, in teh top of the plug, i.e. towards the wall of the mould, contains a temp. sensor, from which the leads continue along a groove in one side of the sleeve. The temp. sensor can be used to regulate the switching-on/off of the heating cartridge, a timing device being used to delay switching on of the coolant after the heater has been switched off. As compared with a more conventional arrangement, in which heating and cooling ducts are incorporated into the walls of the mould, the present system eliminates such ducts and requires only the forming of blind holes at a number of locations in the mould wall. The heating/cooling units are then simply screwed into these holes.
