Title: Cutting device for use in a sewing apparatus
IPC: D05B23/00
Filed: 1973-08-16
Abstract: 1402668 Sewing machines; work cutting DURKOPPWERKE GmbH 16 Aug 1973 [21 Aug 1972] 38657/73 Heading DIG [Also in Division B4] Cutters Z used for cutting V-shaped slits at each end of a pocket opening in a garment, each comprise two blades 27, 28 set at an angle to each other. They are raised to penetrate and cut the material from underneath, by equal amounts if both limbs of the "V" are equal, or by different amounts if they are to be unequal. In addition the support for the blades is rotated when the cuts are to be unequal. A vertical rod 21 is raised by springs 32, 32' when air is released from a cylinder 25 in which the rod 21 slides, and two further rods 22, 23 attached to the first rod by springs 34, 35 are thus also raised. The blades are mounted on these two rods. Two stop-plates 38, 39 each have a stepped profile and determine how far the blades are raised. If the V slit is to have equal length limbs stop-bars 40, 41 carried on The rods 22, 23 respectively abut the same step d, d' respectively on the stopplates. For different length slits the rods, blades etc pivot through e.g. an angle # (Fig 5) and the stop-bars 43, 41 abut different steps (e.g. a g' Fig 7) thus permitting the blades to be raised to different heights. To limit the rotation of the rods, blades, etc, bolts 51, 57, 58 are provided (Fig 5). One of these is raised into its respective bore 52, 59, 60 in a plate 20 which pivots with the rods. If none is raised a bolt 55 in its bore 56 limits the rotation of the plate. Using a piston and cylinder arrangement 54 the plate can be pivoted clockwise or anti clockwise from its centre position to allow unequal cuts to be made first in one side of a garment, then in the other,

Abstract: 1,194,565. Automatic temperature control systems. HONEYWELL Inc. Aug.23, 1967 [Oct. 5, 1966], No.38916/67. Heading G3R. An air heater 14 is variably energized under the control of a sensor 63 and additional heaters 15, 20 are switched into circuit successively as the heating requirement increases, the heater 14 current being decreased when another heater 15 or 20 is switched in. The heater 14 is controlled by a relay 22 whose mark space ratio is varied by a transistor 52 fed from a relaxation oscillator 55 through transistors 54, 53, the bias on the latter being varied with measured temperature by a transistor 61 controlled by a temperature sensitive resistor arrangement 63, transistor 61 being stabilized against ambient temperature variations. When heater 14 is energized at a high level, a circuit 72 is energized which closes switches 24, 40, the latter modifying the potential on a line 64 which reduces the output of heater 14 to a low level. Similarly when the heater 14 is again fully energized switches 25, 41 are closed, further modifying the potential on line 64. The heaters 14, 15, 20 may have unequal ratings, i.e. the heater 14 may have a higher rating e.g. 7À5 K W compared with 5À0 UW for heaters 15, 20.

Title: Fabrication of very thin transistor and other solid state devices

IPC: H01L27/00
Filed: 1967-08-29
Abstract: 1,206,636. Semi-conductor devices. TRW Inc. 29 Aug., 1967 [26 Aug., 1966], No. 39545/67 Heading H1K. A P-type region 40 is formed by diffusion into a shallow N-type pocket of monocrystalline semi-conductor through a hole in a masking layer 58, the diffusion front advancing under edge 61 of the hole. A much thinner masking layer is formed in the semi-conductor surface within the hole. At least part of this layer is etched away to reopen the hole, the mask used being so placed that the part of the original mask adjacent edge 61 is also exposed to the etch out. The etching time is chosen such that all of the exposed thin masking layer is removed but that the exposed part of the original masking layer though thinned is still effective as a diffusion mask. Thus when N-type impurities are introduced to form the region 12 diffusion commences from the same edge 61 as did the first diffusion; this means that the desired close spacing of the two diffusion fronts may be achieved by control of diffusion times. The embodiment described is a transistor with emitter 12, base 40, and collector 36, 38. The emitter (22) and collector (26) metallizations are extended on to the insulation overlying adjacent pockets as are the two base metallizations (24) which contact enlarged portions (14) of the base region (Fig. 1, not shown). (The base metallizations are connected to a single lead.) The structure may be formed from a single monocrystalline silicon wafer which is grooved at its surface, coated with oxide, provided with a polycrystalline substrate 10, and lapped to separate the monocrystalline silicon into isolated pockets. Many transistors may be formed in the one structure and then separated. Reference has been directed by the Comptroller to Specification 1,069,467.

A continuous casting machine of the type in which a co-operating pair of endless sets of articulated mould blocks are driven at the same speed so that over a portion of their run they are in engagement one with the other and define between them a moving mould cavity, has a casing 10 positioned away from the casting and opening towards the mould blocks 11, the casing 10 containing a number of spraying nozzles which are arranged to direct a spray of cooling liquid against the mould blocks 11, and means for providing a reduced pressure within the casing. The mould blocks are cooled during their upward idle run, the casing 10 containing a number of horizontal spraying pipes 13, each having a number of spraying nozzles, each pipe being caused by a deflector 15 to deflect water pouring down the faces of the mould blocks. Air is sucked out of the casing 10 through a pipe 18 and the resulting inrush of air through the space between the mould blocks and the edge of the casing prevents loss of coolant through this space. Water is removed from the casing 10 through a pipe 17. For cooling the mould blocks of horizontal casting machines, the casing 10 is divided into upper and lower chambers, Fig. 5 (not shown), the lower chamber containing the spraying nozzles and the upper chamber the coolant discharge pipe, the two chambers being connected by tubes sealed to and extending through the partition.

Abstract: 1,192,706. Staircase wave generators, tuning radio receivers. C.I.T. COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS. 29 Aug., 1968 [4 Sept., 1967], No. 41288/68. Headings H3P and H3Q. [Also in Division G4] A circuit for generating a voltage variable stepwise to selectable values comprises means for producing a preselected number of pulses, each pulse occupying a time period ito in a pulse repetition period Nto, where i has a maximum value of N, means for averaging the pulses so as to produce a smooth D.C. output signal of value proportional to i and means for changing the integer i so as to vary stepwise the output signal. High frequency pulses from 21 step-up a counter 13 (of capacity N) until it reaches the value i set into a similar counter 11 whereupon a coincidence detector 12 produces a pulse which switches over a bi-stable circuit 16 to terminate the output at its upper terminal and via its lower terminal to close the gate 22. A similar counter 14 of capacity N operating in parallel with 13 continues to count and when it is full its output resets counter 13 and bi-stable 16 so that the gate 22 reopens and the count in 13 restarts. The pulses thus produced at the upper output of the bi-stable circuit have a width proportional to the count i set in counter 11. Averaging at 17 the output provides a D.C. output having an amplitude proportional to i. The output of counter 14 steps up a further counter 15 and when this counter is full it produces a pulse which steps on the reference counter 11 by one. Accordingly the pulse width and D.C. output increase correspondingly in steps. This continues, producing a staircase output wave at 18, until counter 11 is full whereupon a circuit 24 discharges the averaging circuit and the staircase wave returns to zero and restarts. By applying appropriate voltages to A the output wave can be held at any step and voltage at B can cause the counter to reverse so that the output steps downwards. The voltage may be applied to a varicap diode tuning an oscillator so as to cause the frequency to vary stepwise.
