Title: Improvements in and connected with trucks for handling loaded goods platforms
IPC: B62B1/14
Filed: 1921-08-17
Abstract: 184,067. Monro, D. L. Aug. 17, 1921. Hand-trucks.-A hand-truck for use in handling loaded platforms comprises an angle lever frame A, Fig. 1, provided with wheels B so mounted that the forward end D can be inserted beneath a standard platform F and used to lift the further end thereof, the frame having a ledge N, so that after the lifting has taken place, relative movement between platform and truck causes the near end of the platform to rest on the ledge when the handles are raised. The end D carries wheels, rollers, or the like E to facilitate the relative movement, and the platform may have runners beneath it along which the rollers run, while metal strips, rollers, or the like are provided on contacting surfaces of the truck. A second set of wheels O, Fig. 5, may be provided, which set may be detachable or mounted on a pivoted support.

Title: Improvements in or relating to the combustion chambers and valves of internal combustion engines
IPC: F01L7/08
Filed: 1939-07-28
Abstract: 532,713. Valve mechanism ; oil engines. BURNEY, Sir C. D., and BROADWAY AUTOMOTIVE PRODUCTS, Ltd. July 28; 1939, No. 21905. [Classes 7 (ii), 7 (iii) and 7 (vi)] In an engine having a rotary conical valve in the cylinder head forming the combustion chamber an annular projection within the valve forms the mouth of this chamber, which is closed by a cylindrical projection on the piston before the upper dead-centre is reached, a byepass being provided to connect the closed chamber to the cylinder space below the annular projection through a port in the valve. The valve 10 is shown with an internal projection 29 into which enters a projection 31 on the piston, the air or mixture remaining in the cylinder being forced into the combustion chamber with a whirling motion through a byepass 16, 17 and a port 28 in the valve. At the dead-centre position, the byepass is closed by a valve 30 actuated by a cam 34. Fuel may be injected into the combustion space, either in the same direction as the air entering at 16, or oppositely thereto. The valve 10 is oscillated, in a two-stroke engine, by a pair of cams 26 acting on a forked lever 24 which is formed with a toothed sector engaging a pinion 20 on the valve spindle. In petrol engines, the fuel injector is replaced by a sparkplug, which is then uncovered by the valve 10 for fixing. In four-stroke engines, the valve 10 may rotate continuously.

Title: Improvements in systems for reading magnetic tapes
IPC: G11B20/10
Filed: 1959-06-26
Abstract: 902,164. Skew correction. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 26, 1959 [June 30, 1958], No. 21956/59. Class 106 (1). Data characters are recorded in parallel by bit on tracks of a magnetic tape, each track having an associated read-in counter 16 which gates successive bits read from the track into successive positions of a skew buffer register 12: the counts in all the read-in counters 16 are compared with the count in a read-out counter 24 and when it is established that all the read-in counters store a greater count than the read-out counter a signal issues gating the contents of the position in the skew buffer registers corresponding to the count in the read-out counter to an output register. Thereafter, the read-out counter is advanced one count. The bits as they are read from the track control a variable frequency clock 10 (one to each track), pulses from which advance the read-in counter 12 and open a gate 11 (the trailing edge of each pulse advances the counter). The read-in in counter opens, according to its count, one of a set of gates 14 to the skew buffer 12. Both the read-in and read-out counters are duodecimal consisting of a set of four triggers T 1  to T 4  of which the outputs are combined with the outputs of triggers T A  to To (not shown) to give the count of twelve. Comparison of the counts of the read-in and read-out counters takes place in circuits 18, as shown in Fig. 5. Coincidence of an off signal from a trigger of the read-in counter and an on signal from the corresponding trigger of the read-out counter means that the required condition exists. If the read-in counter has passed its twelve-count it issues an overflow signal which is sufficient to indicate a higher count than the read-out counter since this signal is stopped only when the latter has itself counted beyond twelve. The outputs of the compare circuits 18 are applied to an and circuit 22, the output of which initiates the transfer of data from the skew buffer registers. The variable frequency clock is preferably that described in Specification 902,163.

Abstract: 301,103. Igranic Electric Co., Ltd., (Cutler-Hammer Manufacturing Co.). Aug. 24,1927. Drawings to Specification. Push-button control; reversing arrangements.- In a control arrangement for an electric motor working a skip hoist, limit switches closed at the upper and lower limits of travel automatically determine the setting of an electromagnet change-over switch in connection with a controlling push-button, in such a manner that repeated identical operations of the push-button effect alternate forward and backward runs of the hoist motor. An additional push-button is arranged to give reverse runs from intermediate stoppages. A group of resistances shunted across the motor-armature is automatically excluded at the beginning of each run, and is re-included at the end of the run in order to slow the motor down. A further group of resistances in series with the motor-armature is automatically excluded and re-included in sequence with the first group. In each group individual resistance sections are mutually in parallel and are put in and out by means of electromagnetic contactors subject to timing devices. Provision is made for transferring the control from the pushbuttons to a drum switch whereby the operator can give slow or fast runs at will in either direction.

Title: Improvements in electronic counting circuits
IPC: H03K23/82
Filed: 1947-08-12
Abstract: 632,411. Counting-apparatus. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and BAKER, G. T. Aug. 12, 1947, No. 22328. [Class 106 (i)] A cyclic electronic counter having a plurality of trigger stages each including a pair of thermionic valves, the stages being interconnected so that they are transposed in succession in response to successive impulses, comprises a circuit arrangement for indicating the count in which a plurality of gas discharge tubes equal in number to the capacity of the counter are provided, each tube being connected between the high-tension supply or a fixed potential derived therefrom and corresponding electrodes of each of two thermionic valves, the potentials on the electrodes being approximately equal on the count which the tube represents and of such value that the potential across the tube exceeds its striking voltage. In the described embodiments each pair of valves V1, V2, V3, V4, &c. is included in a common envelope, and the valves 'become conducting in the following order: V1, V3, V5, V7, V9, V2, V4, V6, V8, V10, V1, &c., at any given count five consecutive valves in this sequence conducting. Neon tubes N0, N1, N2 ... &c. are connected between the H.T. positive on the one hand and the anodes of two of the valves on the other hand (N0 to V1 and V9; N1 to V3 and V2; N2 to V5 and V4; &c.). Thus, for each of the ten stable conditions of the network there is one neon tube connected between the H.T. positive and the anodes of two valves which are conducting, and the values of the resistances are arranged so that, when this is so, the potential across the neon tube causes it to strike, thus providing an indication of the count. In the embodiment shown in Fig. 1, the pulses to be counted are applied, via a terminal 14, to the grid of a cathode follower valve V11, the resulting negative-going pulses across the cathode load resistance R17 being applied to the cathodes of all five pairs of valves V1, V2 .... The grids of the valves are each connected to the anodes of two other valves and the arrangement is such that at any time, regarding the five non-conducting valves, the grids of four are each connected to the anodes of two conducting valves and accordingly have a potential well below the cut-off point, whereas the grid of a fifth valve is connected to the anode of one non-conducting and one conducting valve respectively. In view of the higher potential on this grid, this valve alone responds to the cathode pulse and fires whilst the opposite valve is cut off and the grid to which its anode is connected is prepared to respond to the next pulse. In an alternative embodiment (Fig. 2, not shown), the pulses from the valve V11 are applied, via condensers, to the grids of the valves V1, V2 ... &c. and the neon tubes are connected to the valve cathodes instead of the H.T. positive.
