Title: Improvements in sewing machines for stitching leather cases
Inventor: HEGGIE JAMES
IPC: D05B15/00
Filed: 1952-11-17
Abstract: 742,478. Sewing machines. SINGER MANUFACTURING CO., Ltd. Feb. 16, 1954 [Nov. 17, 1952], No. 28904/52. Class 112. In a sewing machine of the type in which the needle meets the work at an acute angle, as in stitching diagonally through the abutting sides of leather cases, a needle-guiding member is adapted to be moved towards the point at which the needle will penetrate the work before the needle penetrates the work and to be retracted after the needle has entered the work. The work 5 is pressed against an abutment 4 by a clamp arm 6. The needle-guiding member 7 is in the form of a plunger slidable in guideways 8 and biased away from the work by a spring 9. The needle-bar 3A carries a cam 15 in the form of a bar parallel to the needle 3 and tapered at its upper end. One arm 10 of a double-armed lever pivoted at 12 is engageable with the cam. The other arm 11 of the lever is adjustably engaged with the needle-guide by means of a screw 13. When the needle-bar is raised, the cam engages the cam follower to rock the lever and thereby move the needle-guide towards the work. When the needle descends, the needleguide prevents deflection of the needle as the point of the latter enters the work. Continued descent of the needle brings the tapered portion of the cam opposite the cam follower to allow spring 9 to move the needle-guide away from the work by rocking the lever. A pin 16 carried by arm 10 is arranged to engage the parallel portion of the cam for stopping the movement of the needle-guide when the latter is clear of the needle. Specification 636,728 is referred to.

Title: Discriminating circuits
IPC: H03D1/18
Filed: 1966-06-29
Abstract: 1,104,832. Detecting speech signals in noise. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 29, 1966 [July 1, 1965], No. 29151/66. Heading G1U. [Also in Divisions H3 and H4] In an arrangement for detecting a signal in the presence of noise, or for measuring signal to average noise level, the input signal is full wave rectified and the resulting signal is averaged and stored and compared with the instantaneous input signal, a signal being indicated when the instantaneous level exceeds the average level by a predetermined amount. The indication of signal presence is used to prevent that portion of the input signal being averaged. In the Fig. the signal and noise from terminal 12 is full wave rectified in detection 14, and applied via a non linear circuit 15 having a logarithmic characteristic and a low pass filter 16 to a switch 26 which, when closed, feeds the signal to an averaging circuit comprising resistor 24 and capacitor 25. The averaged signal is fed via a high input impedance unity gain amplifier 27 to one input of a difference amplifier 17 where the averaged signal is compared with the output of the low pass filter 16, to produce a quantized binary output on 13 when the input signal exceeds the average signal by a predetermined amount. The output is also applied as a control voltage to the switch 26 which comprises a symmetrical transistor 40 controlled between its conducting and non-conducting state by a differential amplifier comprising transistors 44 and 45. A clamp circuit including diode 50 provides that the base of transistor 45 never rises above the potential of the base of transistor 44 and that therefore the total current through the pair is maintained constant. The Zener diode 55 is provided to maintain the current drain through the input line 41 constant irrespective of the state of the switch. The amplifier 27 includes a transistor 65 to provide positive feedback to keep the base collector potential of transistor 60 constant and to make the input impedance of transistor 60 high. If an indication of signal to average noise level is required an additional difference amplifier may be connected to lines 18 and 20 to give an analogue output rather than a binary quantized output.

Abstract: 292,952. Reckhard, J. June 27, 1927, [Convention date]. Hatching-appliances.-Eggs are placed in elliptical openings o in trays h provided with runners or rollers n. The trays are placed on projections e extending from pairs of conveying bands s passing over rollers r so driven that each cooperating pair of bands s moves in the opposite direction from the next pair. The trays are thus carried up to the top of a hatching chamber where, in turn, they are moved on to the next descending conveyer, each tray during such movement passing over an adjustable felt or cloth covered ledge i so causing the eggs to be turned. The continuous upward and downward movement of the trays causes the eggs to move through the complete range of temperature in the chamber, egg-turning being accomplished at each shift from one carriage to the next. When the eggs are ready for hatching covers and boxes are secured to the trays which are then inserted in conveyers having sufficiently wide intervals between their tray-supporting members.

Title: Improvements in or relating to the production of metal oxides and other compounds ofmetals
IPC: C22B19/34
Filed: 1919-11-24
Abstract: In the production of oxides such as zinc oxide or of compounds such as basic lead sulphate by the Wetherill process in which the bed fuel or the ore or the reducing agent is briquetted, as described in Specification 137,513, the bulk of the total fuel, for instance 75-85 per cent, is employed as a fuel bed of considerable thickness such as 5 or 6 inches, and the remainder is used with the ore and may be briquetted with it, the layer of ore being, for instance, 4 or 5 inches thick.  By suitably controlling the admission of air to the fuel bed, the addition of reducing-agent to the ore layer may be dispensed with.  When the furnacing operation is finished, the ore briquettes which have retained their form may be readily separated from the sintered fuel ash or clinker in the fuel bed for further treatment if desired, for instance for the production of spiegeleisen.
