Abstract: 1,230,926. Reciprocating motors. HORSTMANN CLIFFORD MAGNETICS Ltd. 28 May, 1969, No. 26969/69. Addition to 1,184,668. Heading H2A. [Also in Divisions G3 and H3] An electromechanical oscillator comprises a primary reed 13 or 14 and a secondary reed 15 or 16 of similar construction to each reed in the pair of reeds described in the parent Specification. A magnet on the secondary reed of the oscillator co-operates with a fixed coil in a driving circuit to maintain the vibration of the oscillator which may operate as a filter or which may provide a rotary output to drive a timepiece. The oscillator may also provide an alternating current having a frequency corresponding to that of the reed. As shown, two reeds 13, 15 and 14, 16 are formed in a nickel-iron alloy strip which is bent into a U-shape and has its centre portion 12 fixed to a support 23. Magnets 17, 19, fixed to the secondary reeds, co-operate with coils (not shown) mounted in bores 22 in blocks 20, 21 and connected in a driving circuit to maintain the vibrations of the reeds. Pins 28, 29 attached to the magnets co-operate with the wavy magnetic track 27 of a wheel 26 to rotate the wheel. In a modification, the driving coils are provided with magnetic cores and are mounted between the limbs of the U-shaped oscillator.

Abstract: 1,258,407. Utilizing energy of radiations. J. CLARK. 10 Dec., 1968 [11 Dec., 1967], No. 58757/68. Heading G6P. A radio-active coating is provided on the skin of aircraft in order to reduce aero-dynamic drag. The energy emission from the coating is controlled by adjustment of the electrical biasing potential. Both beta and alpha emitting coatings are employed and the energy emission from the coating to the air is effected by emission directly into the air or by the excitation of a crystal lattice at the air boundary. In some embodiments, the radio-active material is bonded to the aircraft skin and covered with alternate layers of P and N type semi-conductive layers which have an adjustable bias to control the energy of the alpha or beta emission. PN, NP, PNP, NPN and field-effect junctions may be used. Collimation of the emission is effected by a crystal lattice layer interposed between the radio-active coating and the semiconductive layers. In an alternative form, the radio-active material is alloyed with the semiconductor by ionic bombardment.

Abstract: 1306676 Making packets HAUNI-WERKE KORBER & CO KG 1 June 1970 [15 July 1969 11 Nov 1969] 35469/69 and 55195/69 Heading B5D [Also in Division B8] In a packaging machine comprising hollow mandrels 4 carried by a continuously rotating drum 3, the mandrels 4 are intermittently rotated about their respective axes 7 so as to fold wrapper material therearound to form packets. Tin foil 9 from a reel 11 is severed by a cutting device 12 and fed to a mandrel 4 by a suction drum 8 which initially rotates at a speed higher than the rotational speed of the mandrel 4 and which, after folding has commenced, rotates at the same speed as the mandrel 4. The mandrel 4 is carried on a carrier (41, Figs. 16, 17, not shown) which supports rollers (96, 97) engaging fixed cams (98, 99) so as to rotate the carrier (41) to a position where a toothed rack (68) on the carrier (41) engages a fixed toothed segment (69) and is constrained to rotate once thereby. The leading edge of the tin foil 9 is held on the mandrel 4 by heads 47, 48 carried by respective levers 44, 46 pivoted to the carrier (41) and carrying rollers 79, 86 spring- urged into contact with cams 81, 87. The cam 81 is formed on an arm 82 pivoted to the carrier (41) and spring-urged into contact with a cam 84. A further lever 52 having a suction head 54 which holds the trailing edge of the tin foil 9, is pivoted to the drum 3 and has a roller 88 spring-urged into contact with a cam 89. The rotation of the mandrel 4 starts at a position P 2  (see Fig. 1) and during this rotation the lever 44 is pivoted away from the mandrel 4 to allow the suction head 54 of the lever 52 to place the trailing edge of the foil 9 over the leading edge thereof. The drum 3 then rotates through positions P 3 , P 4  where the end of the foil 9 is folded to form the base of the packet. This folding is effected by a pair of cam-operated folders 118, 119 associated with the mandrel and which form side tucks in the foil 9, these tucks being pressed by a pair of resilient rollers 111, 112. The mandrel 4 then passes by a folder 129 carried by a pair of rotating wheels 127, 128 and operative to down-fold one flap at the packet-base, the other flap then being folded by a cam-operated folder 114. The drum 3 then passes through positions P 5  -P 10  where a paper blank 14 is fed to the mandrel 4 by a suction drum 13, the blank 14 being fed from a storage container 16 and being gummed by a gumming device 18. The blank 14 is folded around the tin foil 9 on the mandrel 4 in a manner analogous to that described above. (For Figs. 1 and 15. see next page.)

Abstract: 1308641 Punching SHOREHAM PRECISION TOOLS Ltd 26 April 1971 [27 Jan 1970] 3844/70 Heading B3W A punch press comprises a fixed tool carrier 20, a movable tool carrier 3, a hold down or stripper 41 slidably mounted in one carrier, an ejector 43 slidably mounted in the other carrier and an electric circuit, for starting and stopping the movable carrier, which includes three switches, switches A and B which are actuated by retraction of the hold down/stripper and ejector into their respective tool carriers and switch C which is actuated by the movable tool carrier during a working stroke, the arrangement being such that actuation of switch C either first or last of the three switches during one working stroke stopping the movable tool carrier. The switches are adjustable and before operation of the press the punch 43 is lowered until it first touches a workpiece and the switch C is adjusted until it just operates. It is then adjusted to correspond to the workpiece thickness minus five thousandths of an inch. In operation of the press the hold down 41 engages the workpiece and is pushed into the toolcarrier against the pressure of fluid in a chamber 17, until it actuates the switch A. The switch C is actuated just before, and the switch B just after, the punch reaches the workpiece. If there is no workpiece between the punch 40 and die 42, switch C will operate first and the press will stop. If there are two workpieces or some other abnormal thickness between the punch and die, switch C will operate after both switches A and B and again the press will stop. At the start of a punching stroke a buffer piston 12 is forced away from a piston 11, with which the hold-down is connected, by low pressure fluid supplied to chamber 44; the pressure is reduced to nil during the actual punching and raised to a high level during the return stroke of the punch for returning the hold down. Chamber 45 is used in the same way for the ejector. The die may be mounted on the movable carrier and the punch on the fixed carrier, the roles of the hold down and the ejector being reversed. The switches A and B can be over-ridden to allow the punch to be inched clear of an obstruction. A solenoid valve (35), Fig. 2 not shown, controls hydraulic operation of the ram 1 carrying the tool carrier 3. If the valve spool jams in the ON position, the electric circuits are coupled to the ram stop circuits as a further stop mechanism.

The throttle valve has a movable valve member 21 which, when actuated, throttles or closes off the re-circulating flow path whereupon the pressure of the pumped fluid increases and the pressurized fluid is supplied to the brake motor for braking. Should a wheel tend to skid the pressure of the fluid pumped will drop and the brakes will be released or partly released. A cross-over valve comprising a valve member having a piston 61 is superimposed on the throttling valve so that if the pumping means fails hydraulic fluid which normally actuates the throttle valve and which is provided by the rear section 11 of a master cylinder flows through the circuit to the brake motor. In the construction shown two pairs of brake motors 56, 57; 30, 31 for the front and rear wheels respectively of the vehicle are provided, a proportioning valve 44 or 76 being interposed between the pairs. A further cross-over valve is provided in the circuit of the front wheel brake motors so that the front brakes may be actuated by fluid from the forward section 10 of the master cylinder if the pumping means fails. An accumulator 48 is incorporated in the circuit for power assistance of the master cylinder if required. Suitable lights or signals 58 are provided to indicate the presence or otherwise of fluid pressure in the circuit.
