Title: A Method of and Apparatus for Driving Posts Mounted on Adhesive Tape into a Panel or into Holes in a Panel
IPC: H01R43/20
Filed: 1969-01-10
Abstract: 1,187,747. Assembling electrical posts on panels. AMP Inc. 10 Jan., 1969 [15 Feb., 1968], No. 1723/69. Headings B3A and B3U. Posts P adhered to one side of an adhesive tape T are driven into a panel PA by forming a bight in the tape around an abutment 20 and moving the tape axially to cause the first post P<SP>1</SP> to be stripped from the tape and moved against a second abutment 5 against which it is pressed by the next adjacent post P<SP>11</SP>, after which the post P<SP>1</SP> is driven axially through the panel PA. The post P<SP>1</SP> is applied against a flat surface 5 of a hammer 2 slidable in a member 9 to which is fixed the post feed block 12. When a ram 1, mounting the hammer 2, is driven downwards the block 12 engages the panel PA after which the hammer 2 is moved relative to the member 9 against the action of a spring 10 to cause the electrical post P<SP>1</SP> to be force fitted into the insulating panel PA by a hammer head 6. The extent of penetration is limited by a mouth 46 of an anvil 42. The post P<SP>1</SP> is guided towards the panel by a recess 15 in a reduced cross-sectional portion 13 of the hammer 2. A member 28 adjacent the surface 5 is pivotable to facilitate threading the tape around the abutment 20 and on to a roll 40. The latter is rotated to axially move the tape. Alternatively, the tape may be moved by attaching a weight to its one end.

Title: Method of preparing lead titanate ferroelectric ceramics
IPC: C04B35/51
Filed: 1964-01-15
Abstract: A ferro-electric composition of the lead titanate type is fired in an oxygen-deficient atmosphere.  The composition may contain lead zirconate or lead zirconate and lead stannate.  Suitable compositions are those described in Specifications 780,673, 818,710 and 867,039. Some of these contain minor proportions of chromium, uranium, strontium, calcium and barium.  Hafnium may occur as an impurity in the zirconium constituent.  In one example, a lead zirconate-titanate composition contains from 0.3% to 1.0% by weight of Cr2O3, the preferred amount being 0.7%.  After a preliminary filling in air, the composition is re-fired in an atmosphere of nitrogen or argon at 1100 DEG  C. to 1260 DEG  C. for one hour.  In order to ensure no excess of oxygen, lead is used in the form PbO for the initial mixture.  In a second example the same firing process is applied to a composition containing strontium.

Abstract: 1,021,713. Protective arrangements. RADIO CORPORATION OF AMERICA. Jan. 18, 1965 [Feb. 5, 1964], No. 2144/65. Heading H2H. [Also in Division H3] A current limiting device having a high speed of response to overloads comprises a transistor 10 in series with an input terminal 14 and an output terminal 16, the transistor 10 and a resistor 12 having two circuits in parallel therewith, the first having a transistor 24 and a resistor 30 whilst the second is in the form of a potential divider 32, 34. When the current in the load connected to terminal 16 reaches a maximum value the volt drop between terminals 14, 16 is such that the potential at a point 33 in the divider 32, 34 is such as to render the transistor 24 conductive. Conduction of this transistor increases the volt drop across resistor 30, thus the transistor 10 is cut off in a regenerative manner to reduce the current in the load. To restore the device to its normal condition the supply at terminal 14 must be temporarily removed. A further embodiment shows an arrangement including two such devices used to control a single-ended push-pull transistor stage operating in Class B or C when the arrangement is self-resetting.
