摘要: A timer, especially for cardiopulmonary resuscitation, to generate multiple series of pulsating signals to be used by one or more rescuers to time different, but related, operations in reviving a victim whose heart and breathing have just stopped. The pulses of each series are repetitive at different rates, and the first pulse of each series starts after a certain number of pulses of a preceding series has been generated.

摘要: An apparatus for placement of electronic components on a fluxed hybrid circuit substrate. In accordance with an automated program, the apparatus at a single work station places with high precision a plurality of chips of various types and physical and electrical sizes on a single substrate. Components are successively placed by a pair of hollow pick and placement spindles operating alternately and having motion in the X-Y planes. Precise location of stored chips is not required; the apparatus orients and centers each chip after selection and prior to placement.
