Title: Video disc player having unitary record-handling platform
IPC: G11B17/032
Filed: 1979-02-12
Abstract: Rails 38, 40 for guiding a sleeved record inserted through a slot 24 and for guiding a pick-up carriage 104 across the record are integral with a platform 34 which, in its raised position (illustrated), receives the record and transfers it to a turntable 26 when lowered. The sleeved record is guided by grooves 42, 44 in the rails and a record extracting mechanism 74 grasps and retains the record during subsequent withdrawal of the sleeve. The platform 34, pivoted on a road 36, supports the retained record before lowering it on to the turntable 26. A further set of grooves 100, 102 and driving racks 110, 112, on the rails guide the signal pickup carriage 104 along a path parallel to the direction of record entry. A translating apparatus 114, 116, 118 drives the pickup carriage along the platform rails at a speed correlated to the speed of rotation of the turntable during playback. The player uses a capacitance type playback system. <IMAGE>

Title: Keyboards for pre-set tuning
IPC: H03J5/14
Filed: 1979-09-24
Abstract: In a keyboard for presetting tuning in e.g. an automobile radio a pivoted bracket 27 is mechanically connected to a tuning system of the radio for programming a memory plunger 14 of each key 10. Horizontal sections 33 (33', Fig. 2) of the bracket 27 are arranged over opposite faces of a fixed support plate 1 so as to engage with plungers 14 of two series of keys 10 one above the other.

Title: Trenching Machine
IPC: E02F5/02
Filed: 1981-10-01
Abstract: The invention relates to a trenching machine in which an endless conveyor type digging assembly is operable to dig a trench. According to the invention, the digging assembly comprises an adjustable parallelogram frame for enabling the operator to maintain a constant digging angle at variable digging depths. One corner of the frame is pivotally connected at (14) to a tractor (10), and a powered digging chain (18) is entrained around its periphery. An hydraulic cylinder (32) is connected between sections (22, 24) of the frame (12) for adjusting the orientation of the parallelogram sections (20, 22, 24, 26). With the digging angle of the frame (12) maintained substantially constant, the digging depth can be increased by collapsing the parallelogram frame (12) with the cylinder (32) and lowering the digging end of the frame (12). After the parallelogram frame (12) is initially positioned into the ground at the desired digging angle, the vertical and horizontal forces generated by the digging end and side sections tend to hold the frame at the desired digging angle, regardless of the ground contour encountered. A control device (38, 40) may also be provided for controlling extension and retraction of the hydraulic cylinder (32) when it is desired that the bottom of the trench (36) remains on a substantially straight line. <IMAGE>

Title: An ultrasonic transducer array
Inventor: GREEN IAN MACDONALD
IPC: G01S7/52
Filed: 1982-01-29
Abstract: An ultrasonic transducer array comprises a plurality (9) of transducer elements in a substantially linear phased array formation, each pair of consecutive elements being connected in series to transmit in- phase and anti-phase signals, so as to substantially suppress at least the main lobe which would otherwise be associated with the array. If the elements have substantially equal impedances, the series connection ensures that substantially equal and opposite voltages, V<+> and V<->, are applied to the two halves of each pair. Additionally, if one half of the array is omitted and a plane reflector (10) is disposed at right angles to the plane of half (9) of the array, a reflected image (11) thereof is produced, thus channelling substantially all energy from the first half of the lobe pattern into the second half of the pattern. <IMAGE>

Abstract: Push bar fittings which extend in longitudinal grooves of the frames of windows, doors, or the like, are provided with holding means by which ribs projecting from the side walls of the groove are engaged from below, with the push bar being mounted for displacement above the ribs. To provide as wide a range as possible for cutting the push bar to length, and, on the other hand, to obtain a good guidance of the push bar ends in spite of that, the push bar is provided at the level of the ribs with a portion correspondingly sloping toward the groove bottom. Consequently, the free end of the push bar then extends in the groove portion below the ribs and is thus prevented from moving out of the longitudinal groove.
