Title: Improvements in or relating to stacking hay or the like
IPC: A01D87/12
Filed: 1927-06-01
Abstract: 294,335. Kirkwood, W. June 1, 1927. Hay bodies.-A rick of hay d in the field is fitted with a pair of brackets a to which tackles are attached by which rick is pulled over on its side and then drawn across the field to a bogie m on to which it is hauled by horses pulling on other tackles, the bogie carrying the rick to the place where the final stack is to be built. The bogie may be brought up to the rick and the rick tipped directly on to it. The brackets a have cross pieces b at their bases formed with claws c to grip the rick; hooks or blocks j, k being fitted to which the ropes of the tackles are attached. The upper ends of the brackets are provided with a series of holes h in which other hooks or blocks, e, f are adjustably attached. In attaching the tackles, a loop 10 on the end of one rope 11 is attached to the hook f at the top of a bracket, carried round the back of the rick and engaged with the hook f of the further bracket being then carried on towards a master tree t near which it is attached to a. rope 12 by a hook 13. Similarly, a rope 15 is attached to the other bracket, carried round the front of the rick and connected to a rope 17 near the master tree. The rope 17 passes round a pulley w on the tree and is carried back to the hook e on the one bracket passing thence to the hook j at the bottom of the bracket and then round the front of the rick to the hook k on the bottom of the other bracket. The rope 12 is similarly fitted at the other side. Horses are attached to the trees u to pull the rick over and to draw it, top foremost, on its side to the bogie. The bogie has its floor m preferably nearly in line with the shafts n and is so arranged that its rear edge is normally about 9 inches off the ground. A two-part purchase r, y, 21, is secured by its block r to each side of the front of the bogie, the rear blocks f being connected bv a rope z that. is passed round the rick after the other tackles have been removed. The falls 22 of the purchases are attached to the tree t when it is desired to pull the rick on to the bogie and the horses attached. To prevent the bogie moving holes x are dug for the wheels. A winch may be substituted for the purchases on the bogie, and a jack may be used at the fore end of the bogie for causing the rear end to be lowered. When the rick is tipped over directly on to the bogie, ropes passing through at the fore end of the bogie are hooked into the bracket ropes, the other end of the bogie ropes being secured to the tree.

Title: Improvements in or relating to electrostatic printing systems
IPC: H01J31/06
Filed: 1958-05-09
Abstract: 871,194. Local copying. DICK CO., A. B. May 9, 1958 [May 10, 1957], No. 14965/58. Class 40(3) [Also in Group XL(a)] Electrostatic recording on a dielectric medium 22, such as paper, is effected by means of a cathode-ray tube 16 having a target formed of a column of wires which extend to the outside of the envelope and are supported in the face plate 38 so that they are insulated from each other. An earthed conducting rod 40 extends parallel to the column outside the tube, and the recording medium is pulled past the wire tips between the tube and rod. In operation, the tube may be controlled by signals derived by scanning an original image in horizontal and vertical directions in the conventional manner. The deflection of the cathode-ray beam along the column of wires is effected in synchronism with the horizontal scan of the original, whilst video signals derived as a result of the scanning are applied to modulate the beam intensity. The movement of medium 22 is synchronized with the vertical scanning of the original. When the cathode-ray beam impinges a wire, the potential of the wire increases negatively towards cathode potential until a discharge occurs between the wire tip and earthed rod 40. The discharge passes through medium 22 leaving an electrostatic charge over an area substantially the same as that of the wire tip. The resulting pattern of charges is rendered visible in a known manner by dusting with powder which is fused to the medium by heat pressure or other means. The medium is preferably made conductive on the face engaging rod 40 and is spaced away from the wire tips by a small distance so as to prevent the medium becoming charged by friction. Reference is made to the use of both camera tubes and mechanical scanning apparatus to scan the original, in the latter case the motor employed for driving the scanning apparatus may also be employed to move medium 22. Details of the target construction of the tube are described with reference to Figs. 3 and 4, not shown (see Group XL(a)).

Title: Integrated Electronic Circuit
IPC: H03K3/356
Filed: 1966-04-06
Abstract: 1,152,367. Transistor amplifier and pulse circuits. SOC. SUISSE POUR L'INDUSTRIE HORLOGERE S.A. 6 April, 1966 [9 April, 1965], No. 15431/66. Addition to 1,098,468. Heading H3T. [Also in Division H1]  The only circuit elements used in the elementary voltage amplifying circuit of Fig. 1 and more complex circuits embodying it, -are IGFETS of the same conductivity type and capacitors all formed in one face of a semiconductor body. With the control voltage V e  at zero an input voltage pulse V 0  gives rise to a corresponding voltage V 1  to render transistor T 2  conductive. C 2  which is smaller than C 1  will thus be charged to a voltage the maximum value of which corresponds to the difference between V 0  and the threshold value of transistor T 2 . At this stage transistor T 2  becomes blocked. On reducing voltage V 0  it remains blocked to prevent discharge of C 2 . If an input voltage with a value > #AC 1 /K 1 , where A is the rate of rise of voltage V 0  and K<SP>1</SP> a constant of transistor T 1 , is applied, transistors T 1  and T 2  become conductive causing C 2  to discharge. A bi-stable setreset circuit (Fig. 6, not shown) comprises a pair of such circuits supplied from a common source and cross-coupled, with a third transistor, through which a control voltage is supplied, connected across each transistor T 1 . In a modification of this one of the elementary circuits is replaced by a capacitor and IGFET connected in series across the source, with a further IGFET through which a control signal is applied shunted across the IGFET. This circuit is used as a memory in a dividing circuit. In the frequency divider shown in Fig. 8, circuit elements T 2 , T 3  and C 2  constitute the elementary circuit. Assuming the input capacitance Cp of T 4  to be charged to render T 4  conductive and T 1  blocked an input pulse V 0  causes Cp to discharge, thus rendering T 2  and T 3  conductive. Since T 2  has a transconductance small relative to that of T 4  discharge will take longer than the rise time of the pulse so that no voltage appears at output 17 before the next input pulse arrives. This pulse will appear at the output to unblock T 1  and block T 2  to allow capacitor Cp to recharge, and thus the cycle is repeated. Two other types of frequency divider stage utilizing different combinations of the Fig. 1 circuit and series combinations of IGFET and capacitor are also described, together with a multistage frequency divider utilizing stages of the various types described.
