Abstract: Arrangement for a mortar in an armored vehicle having a gun laying device. A ball bearing support is provided for the mortar in a traverse on the vehicle and allows for the axial displacement of the mortar to facilitate breech-loading of munitions having different sizes while protecting the interior of the vehicle.

Abstract: An optoelectronic proximity sensor having an emitter which directs optical pulses towards a surface as well as a receiver which is oriented toward the point at which the emitted optical pulses impinge on the surface so as to receive a portion of the optical pulses which are scattered back from the surface. The emitter is connected to a pulse generator which causes the emitter to emit the optical pulses at a given pulse repetition frequency. The pulses received by the receiver are evaluated, this being done by a highpass filter which is connected to the receiver and which itself has a limit frequency that is at least approximately equal to the pulse repetition frequency of the pulse generator. A memory circuit is connected to the output of the highpass filter for storing a series of pulses received by the receiver, the arrangement of the parts being such that the memory circuit is rendered capable of receiving the pulses at the beat of the pulse repetition frequency.

Abstract: A digital clock device includes data storage units and produces switching signals in response to the data stored in accordance with predetermined functions, such as time of day and lapse of time. Switching signals responsive to quantities not related to time can also be produced. Data being stored is displayed as it is being entered into the device. In a disclosed embodiment, the device is used for the control of an electric range. Start of cooking time and duration of cooking for the oven and the individual heating plates can be controlled. Programmed control of oven temperature is also possible.

Abstract: In an electronic digital display control device, a pulse generator is actuated to produce pulses which are fed into a counter to control the setting on the display. A discriminator detects whether the frequency of the pulses exceeds a predetermined frequency limit. If the limit is exceeded, the discriminator connects to the counter a second pulse generator which provides pulses at a freqency higher than the predetermined frequency limit. By so doing, the counter receives a substantially greater number of control pulses per unit of time and sets the digital display very rapidly.

Abstract: A switching arrangement for the control of an adjustable member such as a valve includes a light sensitive switch. Detection of a particular light value enables a frequency divider to transmit an opening pulse to a valve control circuit a predetermined delay period after the detection of such light value. The frequency of an output signal of a pulse generator is varied in response to the opening pulse and the frequency divider transmits a closing pulse to the control circuit after a second predetermined time period of different duration from the delay period. In one disclosed embodiment, control of the frequency divider is responsive to moisture content of soil as well as ambient light level for application in automatic sprinkler systems.

Abstract: An input mechanism includes a plurality of input factor storage units for storing and coding pulses representative of input data. The stored data is transmitted to a data processor and to a decoder for subsequent display. Preferably, the number of storage units equals the number of display terminals on the display device. A selection device directs the pulses produced by a manually controllable pulse generator to one of the plurality of storage units.

Abstract: A timer clock of the type having a time-of-day recording mechanism, a switch electrically connectible to an electric device, an adjustable timer wheel for controlling the switch, and a power source operably connected to drive said time-of-day recording mechanism and the timer wheel. The wheel has a first set of teeth defining a second timing period which is more extended than the first timing period. The power source includes a motor and a drive shaft driven by the motor. The drive shaft carries a first gear adjacent one end thereof for actuating the second set of teeth. The first gear is engageable with the second set of teeth to drive the timer wheel during the second timing period. The timer wheel carries gearing for actuating the switch at the end of a timing cycle. The drive shaft carries a pinion engageable with a second gear, the latter comprising part of the time-of-day recording mechanism.

Abstract: An adjusting mechanism is disclosed for adjusting a digital indicator of an electronic mechanism, such as a timepiece, which includes a first pulse generating mechanism for normally operating the digital display indicator. A second pulse generator includes a pulse former connected electrically to the digital indicator for supplying electrical adjusting pulses thereto. A sensor is operably connected to the pulse former to deliver activating signals thereto for the production of an adjusting pulse. A pulse control member is operably associated with the sensor to control the delivery of activating signals to the pulse former. Either the sensor or the pulse control member is rotatable relative to the other such that activating signals are generated in response to such relative rotation and are generated at a rate which is proportional to the rotational speed of the pulse control member.
