Title: A Digital Frequency Synthesizer Eliminating High Speed Counters.
IPC: H03L7/23
Filed: 1968-07-11
Abstract: 1,172,650. Automatic frequency control. BENDIX CORP. 11 July, 1968 [24 Aug., 1967], No. 33062/68. Heading H3A. A digital frequency synthesizer comprises a first variable-frequency oscillator 10 responsive to a first error signal V 1  for generating a synthesizer output frequency f o , and second 12 and third 18 variable-frequency oscillators responsive to second V 2  and third V 3  error signals for generating second f 2  and third f 3  frequencies respectively. A first frequency spectrum generator 13 generates harmonics of the second frequency f 2 , means responsive to said harmonics and the synthesized output frequency f 0 , i.e. phase detector 15, generating the second error signal V 2 . A second frequency spectrum generator 25 responsive to the third frequency f 3  generates harmonics thereof; means responsive to the third frequency harmonics and the synthesized output frequency f 0 , i.e. mixer 26 generates a complex frequency spectrum from which a desired frequency is selected by filtering means 27, i.e. a low-pass filter. The output of a source of reference frequency 29, i.e. a crystal oscillator is compared with the selected frequency in means 28, i.e. a phase detector, to generate the first error signal V 1 . In the embodiment, the third error signal V 3  controlling the frequency of the third variable frequency oscillator 18 is generated by dividing the frequency f 2  by N in a first divider 20, which is ganged to a second divider 19 which divides the frequency f 3  by N - 1. Dividers 19, 20 comprise cascades of binary counters; the output of divider 19 is applied to a pulse and ramp type phase detector 21 comprising pulse former 21 - 1 to generate narrow pulses which open bilateral AND gate 21 - 3. The output of divider 20 is applied to pulse former 21 - 2 which comprises a ramp generator, the ramp voltage being applied to gate 21 - 3. During the intervals gate 21 - 3 is open a voltage sampled from the ramp voltage is fed to memory 21-4 which may comprise a low-loss capacitor whose discharge path is blocked when the gate is closed, to produce the third control voltage V 3  via filter 22 which removes undesired A.C. components. The first oscillator 10 may comprise a backward wave microwave oscillator, phase detector 28 may like detector 21 be of the pulse and ramp type, while phase detector 15 comprises a diode ring demodulator.

Abstract: 175,773. Miller, A., and Bartholomew, S. A. Nov. 26, 1920. Propelling and steering by vibrating plates; rudders.-In vibrating-plate propellers for boats, the plate is pivoted to the outer end of a frame carried by pintles at the stern and adapted to be oscillated by a tiller, the arrangement being such that the plate can be swung into the frame and act as a rudder. A frame d with integral tiller b is suspended on pintles c on the boat a, and at its outer end is pivoted a plate e. The plate pivot pins f have a handle g which enables the plate to be turned into the frame and be fixed thereto by the stop h, when it is to be used as a rudder. The amplitude of oscillation of the plate on its pivots is restricted. In a modification, the frame is attached to a rudder, which is cut away to receive it. To propel the boat astern, the plate may be connected to levers which permit it to be oscillated in and with the frame.

[Also in Divisions B3 and B5] A shot-gun cartridge case of synthetic resin with a metal reinforcement cap surrounding the head is made by inserting an axially bored core 1 of plastics in a metal cup 4 and placing the twopart slug in a die, Fig. 4, so that, when the plunger 30 is lowered, the plastic is driven upwardly into the annular space around the plunger to form the cartridge wall 48, Fig. 6. Simultaneously the plastic forces the metal into an annular space 86 within the die and so forms the cartridge rim 47. In the base of cup 4 is a primer-receiving aperture defined by tabs 46, which are pressed against the primer 40 by the plastic 49. After placing a skirted overpowder wad 42 over the propellant 41 and inserting the shot charge 43, the cartridge is closed by folding and crimping 45. A globule 50 of heat sealable plastic may be placed at the centre of the folds. The rim 47 may be partially formed before the core 1 and cup 4 are assembled. The synthetic resin may be a linear high-density polyethylene or polypropylene and is worked at a temperature below the crystalline melt temperature.

A railway wagon having small wheels and a low floor may be coupled to a wagon having larger wheels and a higher floor, Fig. 1, by providing vertically adjustable side buffers and draw gear on the first wagon. When both wagons have small wheels and low floors, Fig. 2, then their floors may be converted into a continuous surface for loading by providing hinged metal flaps 19 which bridge the gap between wagons. In another embodiment, Figs. 7, 8, the head stock 7 with the buffers and draw hook 5 may be released from brackets 22 by withdrawing pins 21 and pivoted down about hinge points 20 to provide an extension of the floor 4. A draw bar 23 is provided. In Fig. 1 the buffers and hook may be lowered by withdrawing locking pins from the holes 9 and brackets 8 and reinserting them in holes 10 when the headstock 7 has been pivoted down on links 12, 13. A weight compensating spring 11 is provided. In a modification, Figs. 3 and 4 (not shown), the locking pins are replaced by pin or shafts slidable in guide slots in the brackets 1a. In a further modification, Figs. 5 and 6 (not shown), the headstock 7 may be raised or lowered by a pivoted screw threaded shaft or shafts which may be rotated in a spindle nut pivotably connected to the bracket 8. In yet another embodiment, Figs. 9 and 10, the head stock is divided into two parts 7a, 7b which carry the hook 5 and the double-ended buffers 6a respectively. The part 7b is pivotable about hinge points 20, but the part 7a moves up and down in a motion guided by the co-operation of shafts 17a with slots 16a.
