Title: Electronic tachometer - has angular speed signal derived from position and acceleration signals and with low-pass filter
IPC: G01P3/44
Filed: 1974-02-13
Abstract: The electronic tachometer gives a continuous speed output which results from the combination of discontinuous position and continuous acceleration signals. A differentiating and timing cct. receives the discontinuous position signal, generates timing signals from it and also generates a discontinuous position signal derived from the first signal in response to the timings. The discontinuous position signal thus obtained is an intermittent speed indication. A signal modifying cct. receives the derived discontinuous position signal, receives one of the timing signals from the previous cct. and also the continuous acceleration signal. The timing signal modifies the transfer function of the cct. at preset instant relative to the continuous position signal such as to combine the latter with the continuous acceleration and thus produce the continuous speed signal.

Title: Transfer device - for applying a transfer coating to a cloth piece, from a paper transfer sheet
IPC: B41F16/02
Filed: 1976-11-12
Abstract: The device comprises a number of working positions, associated with transporter elements such as support trays, with a view to the successive completion of a similar number of operations, returning each transporter element to the first position. The device comprises in the order of operations carried out, a first working position for loading, where a first support tray receives the garment piece for treatment, which may be removed to a second working position for the application of the transfer coating, and removed again to a third working position, for unloading of the treated piece. The process relieves the maker of the garment from sheets of release paper freed from their coating, which in repetition work, burdens the operator with problems of handling and storage. The transfer coating is applied to the cloth piece from a very long sheet of transfer paper wound on a feed bobbin, and transfer sheet and cloth piece are entered between the support tray and an upper heated plate. After transfer, the used sheet is rewound on to a collecting mandrel whose rotational movement is timed to each completed transfer operation.
