Abstract: 557,768. Applying wrappers to cakes or yarn packages. KIRKLEES, Ltd., and TONG, W. Aug. 26, 1942, No. 11986. [Class 120 (iii)] Wrappers are applied to cakes or similar yarn packages by a device comprising two relatively movable jaws which are moved to grip a cake placed on them by a hand-operated lever so that the operator is unable to move the jaws to grip the cake until the latter is in position and the operator's hands free. As shown the jaw A' is fixed to a box plate B and the other jaw A<SP>2</SP> is slidable thereon, a pin a projecting through a slot c in a bracket C secured to the table being connected by a link e<SP>1</SP> to a lever E pivoted in an extension c<SP>1</SP> of the bracket and by a pin e<SP>1</SP> and a pin and slot to the part g<SP>3</SP> of a hand-lever G having a vertical member extending through a slot b in the table. The part g<SP>3</SP> of the hand-lever is extended to form a cam g<SP>4</SP> which cooperates with a pawl f pivoted to the lever E and forced by a spring f when the cam g<SP>4</SP> is out of engagement with the pawl, into engagement with a rack F fixed to the bracket c. The jaws are hollowed out at the top and carry semicircular platforms a<SP>1</SP>, a<SP>2</SP>, the wrapper H being placed over the closed jaws as shown before the cake D is placed over the jaws onto the platforms a<SP>1</SP>, a<SP>2</SP>; when the cake is in position the depending parts h of the wrapper are folded up over the top of the cake and the operator can move the handle G in the clockwise direction to open the jaws to grip the cake, the pawl f being forced by its spring f<SP>1</SP> into engagement with the rack F to hold the jaws in position gripping the cake. The parts h<SP>1</SP> of the wrapper are now folded down over the folded parts h and the cake cannot be removed from the device until the operator has moved the handlever G in the anticlockwise direction to force the pawl out of engagement with the rack and then to close the jaws.

Title: Improvements in door-locks for vehicles
IPC: E05C1/16
Filed: 1920-05-05
Abstract: 142,841. Peltz & Kupke. Jan. 29, 1914, [Convention date]. Latches, sliding; locking latches operated by handles.-The parts of a carriage door fastening are arranged so as to prevent unintentional opening of the door. When the latch is in the locked position, the hook end of a rocker e, Fig. 2, on the handle spindle engages behind a lug b of the latch a. On rotating the handle, the thumb d of the rocker engages with the lug b, and forces the latch a inwards, the other end of the rocker moving downwards, allowing the lug b to bear against a spring-mounted block f and force it backwards. On releasing the handle, the latch, tending to move outwards, assumes an intermediate position, shown in full lines, when the inclined surface h of the rocker e, which now moves upwards, is stopped by the inclined surface of the block f. When the door is slammed, the latch is forced back so that the rocker e can swing upwards past the block f and the whole assumes the locked position. The latch a may be locked in the closed position by projecting the cross-bolt i into the notch n in the latch by rotation of the eccentric cam disk m by means of a key. The Specification as open to inspection under Sect. 91 (3) (a) of the Act includes the form of fastening shown in Fig. 4 (Cancelled), in which movement of the handle c<1> to the position shown in dotted lines disengages a sliding check-device f<1> from a groove e<1> in the latch a<1> and acts on a lug b<1> to withdraw the latch. On releasing the handle, the latch assumes the intermediate position shown in full lines, the guide f<1> engaging the groove d' in the latch. On slamming the door, the inclined surface g<1> of the groove d<1> forces the guide f<1> downwards, which allows the handle c<1> to be returned by its spring and the whole to assume the locked position. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to blade mounting for rotary wing aircraft
IPC: B64C27/32
Filed: 1948-05-06
Abstract: 658,985. Helicopters. UNITED AIRCRAFT CORPORATION. May 6, 1948, No. 12495. Convention date, May 20, 1947. [Class 4] A helicopter rotor control system comprises a swash-plate structure 108 mounted independently of the rotor drive shaft and operated through two cyclic pitch control rods 150, 164 and a collective pitch control rod 130, the arrangement being such that the rods 150, 164 move conjointly with the rod 130 upon operation of the pilot's collective pitch control lever 54 and independently thereof when the pilot's cyclic pitch or azimuth control lever 52 is operated. The rod 130 effects axial movement of the swash-plate 108 through a lever 112. The cyclic pitch control rod 150 is operated by fore-and-aft movement of the lever 52 through the rods 140, 146 and a torque shaft 148, and the rod 164 upon transverse movement of the lever through a rod 160 and torque shaft 162. Movement of the collective pitch control lever 54 is transmitted to the rod 130 through a rod 170 and torque shaft 172, and at the same time a compensating link 174 between the cyclic and collective pitch control mechanisms operates to move the rods 146, 160 so that the rods 150, 164 are moved to the same extent as the rod 130, and the cyclic pitch setting is not varied. Each of the rotor blades is carried by a cruciform member providing intersecting vertical and horizontal drag and flapping hinges 64, 66, the pitch control links 102 being connected to the blade horns 100 at points on the axes of the flap pivots 66, so that flapping has no effect on the pitch setting of the blades. Drag movements of the blades are controlled by dampers 90 and an abutment movable between limit stops 82. Blade drooping is prevented by stops 86 on the cruciform pivot members. The horizontal thrust of the tail torquereaction rotor is balanced by mounting the engine so that it is displaced laterally from the longitudinal axis of the machine to cause a slight heeling of the aircraft and a consequent tilting of the rotor blade tip path plane, Fig. 5 (not shown).

Abstract: 142,852. Bosch Akt.-Ges., R. March 15. 1915, [Convention date]. Addition to 142,837. Turning-gear.-The parent Specification describes an electric starting-motor in which the axial displacement of the armature a closes spring contacts s, u which cause full current to be sent to the armature. Initially, a main switch h is closed by means of a push k and coil i, and current is supplied to the field coils b through a conductor l, resistance w, one side of a switch n, and a conductor z<1>; a second conductor z supplies both the armature and the field coils. The resulting displacement of the armature closes the contact s and earths one end of a coil q, which draws down the switch n, cutting out the resistance w and the conductor z<1>, so that full current is supplied to the armature. According to the present invention, the movement of the switch n also earths the coil q by means of a spring-controlled lever 26 engaged by the insulated end 28 of a stem on the switch n; the lever 26 comes into contact with an earthed terminal 27. This arrangement avoids any disturbance of the switch n if oscillation of the armature a allows the contacts s, u to separate.

Abstract: 1307897 Photo-electric indication of flow-rate BENDIX CORP 16 March 1970 [17 March 1969] 12601/70 Heading G1A [Also in Divisions F1 and G4] In a rotary mass-flowmeter a "drag" turbine rotor 36 is driven by a "drive" turbine rotor 22 to which it is coupled by a spiral spring 38, the mass rate of flow being proportional to the product of the speed of rotation and the angle by which the rotor 36 lags the rotor 22. To facilitate determination of said product light reflecting and non- reflecting strips 54, 56, 58, 60 are attached to the outer surfaces of the rotor 36 and a tubular shroud 34, which is coupled directly to the rotor 22 to rotate therewith. A slot 52 is formed in the shroud to expose a proportion of the strips on the rotor 36. Light from a lamp 62 reflected by the strips is received by photo-cells 64 through a window 48. The light reflected or absorbed by the strips on the rotor through the slot varies in accordance with the lag angle. The photo-cells thus produce pulses the duration of each of which is proportional to said product.
