Title: Milling head for cutting arcuate teeth
IPC: B23F21/22
Filed: 1976-03-02
Abstract: In a milling head composed of supporting body (2), milling cutters (5, 6) and clamping ring (3), the milling cutters are in each case arranged step-like in the radial direction as a milling-cutter pair in a common locating groove (4) and with head cutting edges overlapping one another. The milling cutters (5, 6) are constructed as bar-shaped cutting bodies formed over their entire axial length with rectilinear body surfaces and having a trapezoidal cross-section, in which arrangement the rake faces (10, 14) are each formed by a body surface area running rectilinearly over the entire milling-cutter length in both dimensions and enclose an angle ( psi ) of less than 90 DEG  relative to the body surface area running out into the flank cutting edge. This results in the possibility of accommodating more milling cutters in the milling head, of re-grinding the blunt milling cutters in a simpler manner and of reliably re-clamping them in an accurate position. Furthermore, less material is consumed during the re-grinding of the milling cutters. <IMAGE>
Patent GB-948645-A (GB)
Title: Improvements in or relating to reading circuit arrangements for use in magnetic coreinformation stores
IPC: G11C11/06
Filed: 1961-03-07
Abstract: 948,645. Magnetic storage matrices. PHILIPS ELECTRICAL INDUSTRIES Ltd. March 7, 1961 [March 7, 1960], No. 8275/61. Heading H3B. Automatic re-write in a magnetic core storage matrix, the cores of which are read one-by-one and row-by-row; is effected by causing the signal from a core registering a bit to switch an auxiliary core common to the matrix so that a common inhibit wire is deprived of current immediately following read-out and enables a permanently active re-write function to restore the bit in the core. As shown in Fig. 1, the rows A1 to A3 are given half read pulses followed by half write pulses on the single wires a<SP>1</SP> to a<SP>3</SP> shown, or on separate read and write wires. Each row stores a word which is read out by reading the cores in sequence, half read pulses being delivered by the stepping register Z1 to Z4 under command of pulse source S interleaved by half write pulses delivered by the stepping register Z1<SP>1</SP> to Z4<SP>1</SP> under command of pulse source S<SP>1</SP>. A common read winding d delivers output to an amplifier A which over a winding N1 switches an auxiliary core should the coincident half-read pulses switch a core of the matrix carrying a bit. Whenever halfwrite pulses are produced at command of source S<SP>1</SP>, an inhibit winding c is energized to give the equivalent of a half-read pulse to each core and thereby prevent any writing whatsoever. Since the inhibit winding includes a winding N2 of the auxiliary core, however, if a test has been read out of a matrix core the auxiliary core has been switched and the high impedance of winding N2 disconnects the inhibit wire c so that the half-write pulses restore the bit to the matrix core. To write ab initio in the matrix the auxiliary core is switched at the appropriate points of the reading cycle to enable the permanent writing circuits. Instead of using two separate stepping registers Z1 to Z4 and Z1<SP>1</SP> to Z4<SP>1</SP>, a single register of twice the length with stages connected alternately to read and write column wires and stepped at twice the rate, may be used. A suitable register is shown in Fig. 2 where the cores L0, L1, L2 &c. are connected to form a ring counter. A pulse from a source S commanding a half-read pulse in the sequence switches a transistor T1 to conduct and energizes all the core windings in series. One of the cores will be switched to provide its winding with high impedance and this core will be restored to the unswitched state, but at the same time causes a half-write pulse to be diverted to its associated column winding and causes an associated capacitor to be charged. At the end of the command pulse from S transistor T is cut off and the capacitor discharges to switch the next core of the register.

Abstract: 674,389. Endless conveyers. PANGBORN CORPORATION. April 4, 1950. No. 8416/50. Class 78 (i). [Also in Group XXIII] An endless conveyer 46 for a tumbling barrel consists of two chains driven in step by connected sprockets 54 to support overlapping slats 47 which are deflected by two drums 57 to form a work-receiving trough. A second pair of sprockets 55 allows the tension of the chains to be adjusted, while a third pair 56 is mounted on the ends of arms 71 secured to a shaft 72. During a tumbling operation, the arms occupy the position shown, but. when the work-pieces are to be discharged from the barrel, they are swung about the shaft 72 to a lower position by reversing the direction of travel of the conveyer to cause a displacement of the work. Adjustable stops limit the movement of the arms which are connected by cables 87 to counter-balance weights 94. These cables pass over sheaves 93 of tapered helical formation which decelerate the arms prior to engagement with the stops at each end of their travel. Hails 58 support the conveyer over the works carrying area, while rails 100 hold the chains taut when the arms 71. are in the lower position. To lock the arms in their upper and lower positions, the shaft 72 carries a ratchet wheel (not shown) with two sets of oppositely inclined teeth. One set of teeth co-operates with a pawl during upward movement of the arms. while the other set co-operates with a separate pawl during downward movement. The appropriate pawl is brought into operation manually.

Filed: 1974-02-27
Abstract: 1455077 Sewing machines; needle drive SINGER CO 27 Feb 1974 [14 Feb 1973] 8759/ 74 Heading DIG The needle bar of a zig-zag sewing machine is connected to the drive through a latching mechanism so that the needle bar may be disconnected from the drive and held at the top of its stroke by a spring until reconnected. A crank and link 58, 57 (Fig. 2) drive the stud 55 (Fig. 4) to reciprocate along the needle bar 23. When the latch 48 is engaged by pivoting it anticlockwise so that latch surface 51 engages the lower surface 62 of the driving stud, the latching mechanism 42 and hence the needle 'bar to which it is attached is reciprocated. When not latched, a spring 95 biases the latching mechanism and needle bar upwards against a rod 97. When a latch release member 84 (Fig. 5) is pushed upwards by hand (using its lower protruding end 105) it moves up and to the left due to diagonal caming slots 86, 88 through which screw 85, 87 project. This movement pushes it against a lever 81 which rotates about a post 75 causing the other end of the lever (78, Figure 4) to press a lug 79 on the latch 48 to rotate the latch clockwise and hence release it. When the presser bar lever 37 (Fig. 5) is raised it contacts a presser bar guide 34 and pushes it upwards. The block in turn contacts a lug 107 on the latch release member and raises it also, thus unlatching the needle bar.
