Title: Telegraph system with protection against errors due to transpositions
Inventor: DUUREN HENDRIK CORNELIS ANTHON
IPC: H04L1/00
Filed: 1962-05-15
Abstract: 977,211. Telegraphy. DE STAAT DER NEDERLANDEN TEN DEZE VERTEGENWOODIGD DOOR DE DIRECTEUR - GENERAAL DER POSTERIJEN TELEGRAFIE EN TELEFONIE. May 15, 1962 [May 15, 1961], No. 18618/62. Heading H4P. In an error-detecting telegraph system in which code characters are transmitted sequentially in blocks a parity check signal is derived from the characters prior to transmission and is sent with the block. The elements of each character are transmitted simultaneously and are distinguished by their frequency. Three embodiments are described: in the first of these, Fig. 1, the block comprises four characters plus the parity signal. Before transmission a vertical parity check is made on each element position of 5-unit code signals to provide a 5-unit check signal. These five signals are converted to constant ratio 7-unit code and are transmitted, each element position having a characteristic frequency. At the receiver, after conversion to 5- unit code, a parity check signal is derived and compared with that received. In the second embodiment, Fig. 2, the four code characters are first converted to 7-unit code, and a check signal is derived by a vertical parity check on the first six element positions of each character. The seventh element forms a horizontal parity check on the 6-unit check signal, the resultant 7-unit check signal being in constant ratio code. The third embodiment, Fig. 4, uses 8-unit signals. Of the three code characters in the block, the first element has the same polarity, elements 2 to 6 are the 5-unit signals, element 7 is a parity check on elements 1, 3, and 5, and element 8 is a check on elements 2, 4, and 6. The 8 unit parity signal is derived by checking for parity in the manner indicated by the broken lines. If adjacent elements are allotted adjacent frequencies, the parity check illustrated does not refer to adjacent frequencies. A five-to-seven unit code conversion table is given in Fig. 3 (not shown): the service signals I, idle α and idle # are so chosen that one is converted into another only in the case of double transpositions.

Title: Improvements in and relating to superheterodyne radio receivers
IPC: H03D7/10
Filed: 1952-07-25
Abstract: 710,616. Radio receiving circuits. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. July 25, 1952 [July 25, 1951], No. 18878/52. Class 40 (5) In a superheterodyne receiver the same valve is used as a multiplicative mixer on lower frequencies and as an additive, or combined additive and multiplicative, mixer on an ultra-high frequency band. With the switches S1, S2, Fig. 1, in position m, a triode-hexode is operated in the normal way, signals being applied to the inner grid c from input circuit EM, and local oscillations to the outer grid b, from triode section grid a. On ultra-short waves, the switches S1, S2 being in position u, the inner grid c is connected to the input circuit Eu and is also coupled over a condenser C to one end of the ultra-short wave oscillator circuit Ou. An inductive coupling may alternatively be provided. To prevent radiation, the condenser C may be connected to a tapping comprising a balance point on the circuit Ou: the additive mixing then occurs at the outer grid b. In an arrangement, Fig. 2 (not shown) utilizing a valve in which the grids a, b are brought out separately, the outer grid b is connected, via a grid-leak and condenser to the low frequency oscillator circuit Om, so that mixing on ultra-short waves is purely additive. In a modification of this circuit, Fig. 3, radiation is prevented by connecting condenser C to the balance point on the oscillator circuit Ou, and the inner and oscillator grids, c, a are connected together by switch S1 when in position u. Alternatively, the switches may be arranged so that additive mixing occurs at the outer grid b.

Abstract: 856,282. Foundry-plant. BADISCHE MASCHINENFABRIK A.G. June 14, 1957 [June 15, 1956], No. 18887/57. Class 83 (1). In a method of separating and separately feeding the parts of assembled, shaken-out, moulding-boxes to a moulding-machine, the cope is first lifted from the drag through a distance exceeding the length of the centring- pins connecting the parts together, whereafter the two parts are lifted together while maintaining said distance between them until the cope, by conveying means arranged above it, is moved on to a roller conveyer running to the moulding machine while the lifting movement is interrupted, whereupon the drag is then lifted until it is also fed to the roller conveyer leading to the moulding-machine, the operations being effected automatically. Assembled boxes O, U, are fed by a conveyer 1 leading from the shakeout station to a frame member 5, the copes being received on rollers 6 carried by the frame, and the drag being supported on a conveyer portion. 7 resting on fixed supports 8. The frame is carried by a lifting-table 4, and entry of a box into the frame member actuates a limit switch 5 to cause the table to be raised. The drag, being supported on the fixed supports 8, remains stationary until the table has risen a distance a, sufficient to extract the centring-pins 11 of the cope from the corresponding holes in the drag, whereafter the dragsupport 7 is engaged by the frame and moves upwardly with it. Actuation of a switch E2 by a cam 9 on the frame, halts the upward movement of the table, and an endless element 15 moves the cope from the frame 5 on to the conveyer 2 leading to the moulding-machine. At a predetermined distance from the frame, the cope actuates a limit-switch E3, causing the table to rise until the drag may be moved by the element 15 to the conveyer 2, the upward movement being halted by a stop in the cylinder 3. Operation of the limit-switch E3 by the drag then causes the table to return to its lower position for commencement of a new cycle of operations.
