Patent DE-2208709-A1 (DE)
IPC: G10L13/06
Filed: 1972-02-24
Abstract: 1316204 Speech synthesizer INTERNATIONAL BUSINESS MACHINES CORP 2 March 1971 5739/71 Heading H4R Frequency spectrum generator, particularly for synthesizing speech, comprises a data store for storing digital samples of a periodic waveform taken at sampling intervals smaller than the waveform period, and a control device operable to read-out the samples at the original sampling intervals or multiples thereof. As described the data store 2, Fig. 3, stores in respective rows the digital values of samples of respective different frequency waveforms, each sample represented as the change in value with respect to the previous sample. The rows feed respective accumulators 8-15 to provide the output signal of the selected frequency according to the address stored in 5. The rate at which the signal samples are fed from store 2 is governed by the division table 1 under the control of address store 4. The division table 1 receives clock pulses from generator 19 and can then supply pulses at the original sampling rate of the samples in store 2, or at any one of a range of predetermined submultiples thereof, to address increment 7 to cause the reading out of samples from store 2 at the appropriate rate. In addition the amplitude of the signals fed out is controlled according to the information set into an address store 6 which, via an amplitude store 3 controls the accumulators 8 to 15 to provide the appropriate amplitude weighting. Phoneme counter 20 is provided to cause new information, in respect of the frequencies to be generated, to be fed into the address circuits 4, 5 and 6, after every 25 Msecs. Pitch counter 21 is used to provide smooth transitions between adjacent speech sounds by superimposing some components of one speech sound on the following speech sound by controlling the address circuits to read out both signals for a short time on transitions. A total of 5 frequencies may be generated simultaneously at any one time, three relating to a new speech sound and two relating to a previous speech sound to be superimposed on a new sound during the transition period between the two sounds. An alternative system, Fig. 4, uses a functional memory 32 which may be of the type of Specification 1,186,703 to perform the functions of division table (1 of Fig. 3), address incrementer (7), accumulators (8 to 15), combiner (16), amplitude store (3) and phoneme and pitch counters (20 and 21). The organization of the functional memory is described with respect to Fig. 5 (not shown).

Title: Resistor has resistance layer on cylinder dividing into two - with two helical grooves to give two externally-connectable resistance paths
Inventor: NERSTHEIMER KLAUS DIPL-ING
IPC: H01C17/24
Filed: 1973-08-22

Title: Ground coking coal storage system - prevents spontaneous combustion through oxygen access by pressuring bunker with inert gas
Inventor: MENDES MARIO DR ING
IPC: C10B31/00
Filed: 1974-11-16
Abstract: The access of oxygen to ground coking coal during transport and bunkering is prevented before it is passed to the preheating plant ready for charging in coke ovens. An excess pressure is produced in an intermediate storage bunker by admitting an inert gas through a pipe with a control valve. The feed rate of the admitted gas is controlled by servo valve which is adjusted as a function of the inside pressure. This reliably prevents spontaneous combustion of fine coal prior to drying and heating for charging into coke ovens.

Title: Moving fibre cakes for fibreboard - scattering fibres on transport belt, compressing them with thin film of adhesive to form fleece, and removing to main transport belt
Inventor: METS ALBERT DE
IPC: B27N3/20
Filed: 1974-12-10
Abstract: Regularly distributed fibres e.g. for making fibreboard consisting of two outer layers of fine fibres on opposite sides of a central layer of coarser fibres, are moved by scattering the fibres at three places on a first transport belt for transporting towards a main transport belt, the first transport belt passing over a blade-shaped plate at the place where the fibres are delivered onto the main transport belt. The fibres forming the lower outer layer are compressed under a thin film of adhesive material, in order to form a fleece which can be moved from the first transport belt onto the main transport belt, without risk of tearing or deforming.
Patent DE-2460502-A1 (DE)
Title: Quick make and brake coupling for hoses - requires only small coupling force, while coupling is carried out without spillage
Inventor: MOMBERG WOLFGANG
IPC: F16L37/46
Filed: 1974-12-20
Abstract: The coupling incorporates a locking sleeve which can be moved axially against spring force, and an internal valve which is closed when the coupling is undone. Pressure of the working medium acts against the valve, which can be opened by a second sleeve. To undo the coupling, it is first necessary to displace the locking sleeve axially. This sleeve cannot be moved when the valve with operating sleeves are in the open position. To open or close the valve, the second sleeve is rotated. Rotating movement of the sleeve is transformed into axial movement of the valve. The spring which acts on the locking sleeve, reacts on the valve operating sleeve in such a way that the valve is loaded into its closed position.

Title: Highly-stable table with legs of oval tubing - have main axes of tubes facing table centre providing rigidity in all directions
Inventor: SCHAFFITZEL HERMANN
IPC: A47B13/06
Filed: 1975-03-11
Abstract: The table is provided with legs (1, 2, 3, 4) of oval tubing wherein their cross-sections have a secondary axis and a larger main axis perpendicular thereto wherein the main axes of all the legs are aligned inclined to the centre of the table. In this way the table has the same relatively high rigidity in all directions and can be readily displaced over a carpeted floor since the resistance to displacement is surprisingly less than when all the legs are aligned in the same direction. The legs (1, 2) are preferably connected by transverse bars (6-9) whic adjoin the side faces (10) running parallel to the main axis and together form a frame. These transverse bars are preferably made of sections with such dimensions that the sectional planes in the case of sections parallel to the side faces of the legs do not ecess the flat area of the side faces. The transverse bars can thus be cut straight to length.

Title: Synchronising device for TV systems - uses synchronising pulses whose frequency fluctuates and has pulse generator
Inventor: HENLE MANFRED
IPC: H04N5/06
Filed: 1975-04-08
Abstract: The synchronising device for television systems uses synchronising pulses whose frequency fluctuates, and includes a pulse generator. The pulse generator generates, from clock pulses, all pulses necessary for the television system operation. Synchronisation pulses for line deflection are applied to a frequency multiplier which generates, from the synchronisation pulses, pulses of a frequency suitable for the pulse generator control. The multiplier output is connected to the pulse generator input and in case of a synchronisation pulse failure, the pulse generator is connected to an oscillator whose output frequency is equal to that necessary for the pulse generator control.

Title: Rubber sprung rail wheel - with prestressed rubber cylinders in matching semicircular recesses of tyre and rim
Inventor: NELKEN EWALD
IPC: B60B17/00
Filed: 1975-04-10
Abstract: Both the inner diameter of the tyre of a flanged wheel to run on rails and the outer dia. of its rim have semi-circular recesses. Cylindrical rubber elements fit into these recesses and have a central bore for a bolt to apply a prestress to them. Washers of an outside diameter greater than that of the rubber elements are provided at both ends. The rubber elements are inserted without any prestress before they are tightened so that no special tools are needed. The elements cannot shift in the peripheral direction so that they retain their functional reliability even in emergency braking conditions from a high speed. Both tyre and rim are securely located against lateral movements.
