Patent ES-439574-A1 (ES)
Title: Liquid fuel injection pumping apparatus
IPC: F02M41/14
Filed: 1975-07-19
Abstract: A liquid fuel injection pumping apparatus includes an injection pump to which fuel is supplied by a feed pump by way of a throttle which includes an axially movable member. The pressure of fuel upstream of the throttle is controlled by a valve so that its pressure varies in accordance with the law RN2. The apparatus also includes a further valve which provides a substantially constant pressure and this pressure is applied to a piston by way of a further orifice the size of which depends upon the setting of the throttle. The further piston influences the timing of injection of fuel by the apparatus and in addition a pressure which is proportional to the square of the speed at which the apparatus is driven, is generated and is also used to influence the timing of delivery of fuel.

Title: Space stage in a PCM-exchange
IPC: H04Q3/52
Filed: 1977-04-29
Abstract: PCM words transmitted on a number of incoming and outgoing links during time slots according to a time division multiplex system are space interchanged by utilizing a circulating shift register wherein at the beginning of their allotted time slots, each of incoming PCM words is registered each in an associated shift register stage. The circulating shift register is stepped by a clock pulse so fast that each PCM word is stepped through all shift register stages during the respective time slot. Control words, each associated with one of the time slots and with one of the outgoing links, determine during which clock pulse an outgoing link is connected to the output of its associated shift register stage. A buffer memory arranged between the circulating shift register and the outgoing links re-establishes the correct time division multiplex system for the outgoing PCM words.

Title: Trash incinerating oven
IPC: F23G5/44
Filed: 1977-11-29
Abstract: The combustion chamber of the oven is bounded at the top by a lid which can be swung open and at the bottom by a grating. The grating has one or more sections which pivot about an axis to dump slag. A hollow interior of the grating forms a section of the exhaust gas system.
